The clutch plate, release lever synchronous operation with the engine crankshaft, while the clutch release fork along the output shaft can move axially to dial directly release fork lever is clearly not isolated, separated by separating the bearing allows the clutch lever while rotating an edge axial movement of the output shaft, thereby ensuring smooth clutch engagement can be separated and soft, reduce wear and extend clutch life and the entire drive train.

Clutch release bearing element.

 Automobile clutch release Bearing test machine are one of the more important parts, if poor maintenance failure, will not only cause economic losses, but a rather cumbersome disassembly, need to spend a lot of hours. Therefore, to ascertain the clutch release bearing failure causes, and in the use of reasonable care and maintenance of the extended release bearing life, improve labor productivity, and achieve better economic efficiency are important.
Automobile clutch release bearings and units, the important components for the automotive, its main function is to move axially through the bearing, automotive engine and transmission to achieve the combination between or disconnected, thus making the car a smooth start, shift, parking, and automotive driveline overload protective effect. These bearings are self-lubricating, low vibration, smooth clutch, long service life, for automotive clutch release bearings best choice. Bearings with inner and outer rotation, self-aligning bearing units can push, pull-axial displacement seat with seat and without other structural. Bearing assembly is simple, adjustable axial gap, the need to fully consider the use of the axial load. Clutch release bearing and its units under action principle, structure type and work performance following categories: automobile clutch release bearings and bearing units and units push pull Bearing unit bearing units non-aligning bearing units automatically aligning bearing units non-aligning bearing units with rotating outer ring non-rotating inner ring bearing units Spherical self-aligning bearing units.

Low impact energy

  This standard yaw, pitch wheel bearing rings cryogenic impact energy requirements: -20 ℃ Akv not less than 27J, cold condition Akv value can be determined in consultation with the user. Wind turbines may operate in very cold areas, the ambient temperature as low as about -40 bar, the bearing operating temperature of about -20 ~ C, bearing in low temperature conditions must be able to withstand large impact load, therefore, requires the bearing rings The material must be done after quenching temperature impact test, take part on the bearing rings made of sample or with the same performance and the same rings under the sample heat treatment conditions, at -20 ~ C environment to make impact function tests.
Bearing ring
 As the wind clutch bearing transmission accuracy is not high, but relatively large diameter ring gear, gear modulus is relatively large, therefore, the general level of accuracy required by GB/T10095.2---2001 gear in the 9 or 10. However, due to operating conditions between the pinion and ring gear bearing has an impact, therefore, the bearing ring gear tooth surface to be hardened pinion tooth surface hardness generally 60HRC, taking into account other life design, hardened gear tooth surface hardness requirements of not less than 45HRC.
Clearance
 Yaw, pitch bearings have special clearance requirements. Relative to the yaw bearing, pitch bearing the impact load is relatively large, the wind to shake the leaves are large, so they requested the pitch bearing clearance should be zero or slightly negative clearance clearance values, so that the vibration situation bearing can be reduced under fretting.
Requirements for the small yaw bearing clearance values, ie 0-501 ~ m. Further, since the wind turbine yaw and pitch rotation of the bearing by the drive motor, the bearing clearance in the negative state or a small clearance in order to drive the motor can be driven, Therefore, the bearing assembly is required after the starting frictional load measurement torque, specific torque values ​​differ according to the host of the drive system are not the same.
 Preservative treatment
Work in the field of wind turbine equipment, and yaw, pitch Bearing manufacturer the exposed part will be subject to atmospheric pollution and high humidity environments may cause corrosion of the bearing base, so the exposed yaw and pitch bearings the site requirements for surface corrosion treatment, commonly used galvanized. If necessary, outside zinc coating paint protection treatment

Technical Requirements

  A material This standard specifies the yaw, pitchBearing test machine ring material selection 42CrMo, heat treatment with the overall quenching, after quenching hardness 229HB-269HB, part adopts raceway surface hardening, quenching hardness 55HRC-62HRC. As the wind turbine yaw, pitch bearing the force complex and bearings withstand shock and vibration is relatively large, therefore, requires both bearings to withstand impact, but also bear a greater load. Wind turbine host life requirements for 20 years, bearing the cost of installing a larger, thus requiring yaw, pitch bearing life have reached 20 years. Such matrix hardness of the bearing rings 229HB-269HB, able to withstand impact without plastically deformed portion while the raceway surface hardening hardness 55HRC-62HRC, contact fatigue life increases, so that the bearing long life requirements.

Three new standards introduced wind turbine bearings

   Wind turbine bearings can be roughly divided into three categories, namely: yaw bearings, pitch bearings, transmission bearings (main shaft and gearbox bearings). Yaw bearing mounted on a tower and a connecting portion cockpit, the pitch bearing mounted on the root of each blade connected to the hub portion. Each wind turbine equipment with a yaw bearing and three pitch bearing (part-megawatt wind turbines for the following non-adjustable blade, can not pitch bearing).
A code method
  Wind turbine yaw, pitch bearing code method employs JB/T10471-2004 turntable bearing the code in the method, but in the wind turbine yaw, pitch bearings appeared double four point contact ball slewing bearing, and this structure bearing the code is not provided in JB/T10471-2004, therefore, increase the standard double four-point contact ball slewing Precision bearing the code. Since single-row four point contact ball slewing bearing structure type code with 01 that, while the structure type code 02 indicates the double ball slewing bearing structure, provides 03 indicate double four point contact ball slewing bearing structure.

Luo axis wind turbine bearings borne through the GB national standard prequalification committee

  June 28, hosted by the Los axis wind turbine wheel bearing prepared "Rolling wind turbine yaw, pitch bearings", "wind turbine bearing spindle bearings" two national standards, through the National Standards Committee bearing pre.

Since 2007, hosted by the Los axis compiled Republic of China Machinery Industry Standard JB / T 10705-2007 "Rolling wind turbine bearings" since the promulgation, for our wind turbine bearings in the design, manufacture, testing, inspection, and wind turbine bearings in the series, specialization, standardization, generalization has played a positive role. However, due to the standard required in terms of wind turbine bearings general and not specific, operational, and normative execution is not strong, limiting the rapid development of wind power industry. Therefore, in order to meet the wind power companies higher demands on bearing performance, the company according to the National Standards Committee and the China Machinery Industry Federation arrangements undertaken the preparation of national standards which two tasks.

In the pre-trial conference, Director of the National Standard Authority bearing Yang Wei, State Power, CRE and other users of the expert review group composed of representatives of detail listened Luo axis of the wind turbine bearing two standard preparation instructions cum draft standard reports and combined with the actual wind power industry these two standards presented a detailed revisions. Eventually the two standard pre-trial through the National Standards Commission.

We are business units of wind power bearing and thus the development of industrialization,

the lack of common technology platform. For multidisciplinary wind power bearing, the light relies on the strength of a single enterprise is difficult to thoroughly master the relevant technologies. Moreover, in the face hot market, companies are rush into battle, the wind power bearing conditions, technical requirements and the lack of in-depth study process. We believe that the field of wind power bearing into the enterprise, between them both competitors and should seek in the wind power bearing common technology aspects of strategic cooperation. If several wind power bearing companies to unite and to absorb universities, research institutes join, joint research, and to seek the government's policy slewing ring for wind power bearing common technology research and development, will greatly enhance our design and manufacture of wind power bearing technology. This is a very difficult but must be addressed.

High-altitude wind turbine operation in the field of wind power bearing poor working conditions

 temperature, humidity, load changes, to withstand impact loads and overturning moment. Wind power bearings, requires the use of 20-year maintenance-free, thus requiring wind power bearing long life, high reliability. At present, the domestic wind power bearing volume use only two or three years, bearing life and reliability has not yet been tested. It can be said, for bearing manufacturers, for their manufacture bearing life and reliability of the heart has no bottom, the user is not assured. Especially gearbox bearings, a gear box production lines of business CEOs, said: "Bearing delivery can not guarantee that we very much hope that wind power gearbox bearings can domestically, so as not to be controlled by others, but until now, no one bearing enterprises able to produce their own gearbox bearing life and reliability of offerings to ensure that can meet the requirements. "Faced with this situation, we have to break the hard research, development and application of wind power bearing reliability design technology, manufacturing technology and reliability reliability test technology to powerful, compelling software and hardware, so that our own production of wind power bearing life and reliability of their own heart bottom, but also allows users to rest assured.
(Four) that we should aim at the world wind energy industry forefront of technological development, followed by wind power equipment trends, synchronous or advanced research and development of wind power Bearing manufacturer  With the blower unit capacity is increasing, from land to offshore wind farm development, wind turbine technology has been increasing. We can not wait for the launch of the new host, only to develop supporting bearings. To work with the wind turbine equipment manufacturing companies formed a strategic alliance with the host synchronous development, even ahead of the research supporting bearings. For some cutting-edge technologies, such as yaw, pitch bearing, some multinational underway to replace the cross roller slewing bearing Four point contact ball slewing bearing research and development work. Again, Japan NSK Bearings manufactured gearbox selection of its self-developed STF (Super-TF) steel and HTF (Hi-TF) steels. Both the residual austenite content of steel to the optimal design can alleviate the stress concentration caused by the indentation, so that the bearing in the gearbox lubrication conditions such as pollution, but also to achieve long life. Another example is the German Laobo anti-wind power company based on bearing lubrication and failure analysis of in-depth research, are being made to GE's entire lubrication program, etc., must be highly sensitive, rapid follow-up. In addition, wind power bearings are now universal bearing, part of which is to develop into a special bearing, this is a trend. We must individually designed well ahead of the research work.

China's wind turbine bearings supporting the development and industrialization issues to be addressed

(A) the wind power industry has a huge real market and broad market prospects, but the wind power industry is capital-intensive and technology-intensive high-risk industries. The face of the wind power industry, the rapid development of the situation and the huge market demand, China's bearing industry formed a wind power bearing investment. However, in stock and investment boom behind the lack of market for wind power bearing depth analysis of the market for wind power bearing huge investment risk, market risk and technical risks underestimated. In this regard, we have a further bearing industry enterprises issued a warning to prevent the emergence of wind power bearing irrational investment. Bearing enterprises in the wind power Bearing test machine for big investment, be sure to the world and China's wind power industry total size, actual and potential domestic and foreign wind power bearing market, competitors may occupy the market share, the companies have much market competitive space, through the efforts of the enterprise can enter the advantages of wind power equipment manufacturing enterprises of the industry chain, etc., for serious and sober analysis. Those who lack technical reserves, there is no strong technical support for enterprises, involved in wind power bearing market, we must be careful.
(Two) Currently, wind power bearing R & D and industrialization is very uneven. Since yaw bearings and pitch bearings single set of sales in high value-added, technology is relatively easy to enter the field of wind power bearing the manufacturers are concentrating on the beginning of the yaw bearings and pitch bearings,bearing manufacturer major domestic manufacturers has formed the production capacity of the planning objectives and a rough estimate of about 40,000 units, has far exceeded the needs of the domestic market. However, spindle bearings, generator bearings and gearbox bearings in the development and industrialization of inadequate attention. Especially gearbox bearings, bearings made now almost none to enter this field. Only a few samples of competitive enterprises started business in the host or components installed for testing. Wind power equipment manufacturers in order to host and component manufacturing organization conducive to the production and quality control, the need to Taiwan allotments bearing manufacturers supply bearings. Therefore, interested in market share in the wind power bearing a place of business, not only to the development, production yaw, pitch bearings, but also to the development, production gearbox bearings, spindle bearings and generator bearings, and strive to become Taiwan allotments available, into the wind power equipment OEMs and parts plant (generator factory accelerator manufacturer) industrial chain.

The key technology of wind power bearing

Wind power bearing manufacturing, to meet the technical requirements on the basis of the above, with special focus on the following key technology research and application -

Generator bearing manufacturer  and cylindrical roller bearings deep groove ball bearings. By these two bearing structure design, processing methods to improve the production process controls and related components cleanliness preferable to lower the vibration noise of the bearing, the bearing

Gearbox mountings

Gearbox bearings in many types, mainly by gearbox gear oil lubrication. More metal particles in lubricating the bearing life is greatly shortened, therefore required to adopt a special heat treatment process, so there raceway surface compressive stress, reduce particulate impurities raceway on the degree of sensitivity, improved bearing life. At the same time according to the working conditions of the bearing, the bearing slewing ring further optimized design, improved bearing processing method, and further improve bearing performance.

Blade spindle bearings (24044CC)

Blade spindle by two spherical roller Precision bearing. As Blade spindle bear the load is very large, and very long shaft, easily deformed, therefore, requires the bearing must have good self-aligning performance.
Determining internal bearing and cage structure parameters of the structure, the bearing has good performance and long life.

LYC Bearing Adds newcomer wind power products

Among them, the 3 MW wind power spindle bearings development process, independent research and development efforts to increase R & D team, in a certain part of the raw materials, the structural design of the formation of the core technology, to seize the market for the products has laid a good foundation. Meanwhile, in the product processing, large bearing plants and holding companies Luo axis wind bearing manufacturing department also overcomes product accuracy requirements, processing difficulty and other difficulties, strict process control each process to ensure that the products comply with the set of all subsequent Technical indicators have reached the technical requirements. The successful development of these two slewing ringto fill in gaps on such products will become LYC wind power products group and a new economic growth point.

TIMKEN bearings how to carry out regular maintenance

In order to give full play TIMKEN bearings and long maintained its proper performance, you must do a good job of regular maintenance (periodic inspection).
By appropriate periodic inspection, so that early detection of failure to prevent accidents in the first place, to improve the productivity and economic importance.
1, cleaning
The angular contact ball bearings removed for inspection, photography and other methods to do first with the appearance of records. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings.
a, bearing cleaning of rough wash and sperm washing and can be placed in the bottom of the container used metal grid.
b, coarse wash, brush, etc. used in the oil or grease removal adhesive material. If turning point in the oil TIMKEN bearings, attention and other damage due to foreign objects rolling surface.
c, sperm washing, in the oil slowly rotating bearings should be carried out carefully.
Commonly used cleaning agents for the neutral water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent filter should always be kept clean.
After cleaning, immediately TIMKEN bearings coated rust grease oil or rust.
2, check with the judge
In order to determine the angular contact ball bearings removed can re-use, to focus on checking the accuracy of its size, rotation accuracy, internal clearance and the mating surface raceway, cage and ring.
On the inspection results, may be used to bearing or bearings were judged proficient.
Determine the mechanical properties and the criteria according to the degree of importance and checking cycles vary. If the following injury, the bearings must not be reused and must be replaced.
1) bearing parts breakage and defects.
2) rolling surface raceway material peeling.
After installation of the bearing, if not carefully for alignment, alignment may lead to angular contact ball bearings subjected to additional load, friction and vibration. These may accelerate fatigue and reduce bearing life, and may damage other machine parts lifespan. In addition, the increased vibration and friction may significantly increase energy consumption and risk of premature failure.
3, the basic condition monitoring
During use, often the basic operation of TIMKEN bearings for monitoring external conditions, such as temperature, vibration and noise measurements, and so on. These regular inspections will identify potential problems and prevent unexpected machine stop, so that production plans are realized, to improve plant productivity and efficiency.
4, re-lubrication
During operation, the bearing requires a correct re-lubrication, perfect its performance. Bearing lubrication methods, divided into grease and oil lubrication. In order to play well bearing function, first, to select suitable conditions, the use method for the purpose of lubrication. Only consider lubrication, oil lubrication dominant. But there can be simplified grease around the bearing structure of expertise.
5, Remove
When the bearing will reach its final use period of time, it should be replaced. Although bearings can no longer be used, but the right to remove the original angular contact ball bearings, and timely replacement of new bearings, new TIMKEN bearings for extended life can play a good role in promoting. First, remove the appropriate use of methodological tools will help prevent damage to other components of the machine, and the second, incorrect clutch bearing be removed operator hazard.

Install accuracy calibration method

The angular contact ball bearing into the shaft, the mounting accuracy calibration sequence is as follows (in order of shaft diameter of 60 100mm lathe for example):
(A) measuring the shaft and the bearing hole slewing ring with precision bearings, with the requirements are as follows [1]:
Take the inner ring and the shaft interference fit, the amount of interference 0 ~ +4 μm (at light load, high precision is 0); take the outer ring and the bearing bore clearance fit, clearance volume 0 ~ +6 μm (but at the free end of the bearing use angular contact ball bearings, also increase the gap); shaft and housing bore surface roundness error in 2μm or less, used in the bearing spacer parallelism in 2μm or less, the inner face of external shaft shoulder end of the beating in the 2μm the following; shoulder block bearing bore axis of the beating in the 4μm for the following; inner end face of the spindle axis of the front cover of the beating in the 4μm less.
(2) fixed end mounted on the shaft front bearing
Cleaning the bearing with clean kerosene thoroughly cleaned, for grease lubrication, the first containing 3% to 5% of the grease into the bearing organic solvent for degreasing, then the grease gun to the grease filled in the bearing quantitative (representing bearing space volume of 10% to 15%); heating bearings make heating 20 ~ 30 ℃, oil presses the bearing onto the shaft; tight sets will be pressed on the shaft and in the appropriate pressure against the bearing face axially positioning; would spring balance tape volumes in the bearing outer ring, with the measurement method of starting torque required preload check whether there is a significant change (even if the bearings are correct, but due to the deformation of the cage match or pre-load is also may change).
(3) the bearing shaft assembly into the housing bore
Heated seat hole so that heating 20 ~ 30 ℃, with a continuous gentle pressure on the bearing? Shaft assembly into the housing bore; adjust the front cover, the front cover of the fastening amount of 0.02 ~ 0.05μm, the outer end face of the bearing seat benchmark, the dial gauge header conflict in the journal surface of the shaft rotation measure its beating, requires the following error 10μm; positioning a dial indicator on the shaft hole header conflict with the rear surface of the shaft rotation to measure the bearing front and rear seat hole concentricity.
(4) the free end of the bearing may be selectively placed in a position offset bias, after installing the bearing housing supporting position, offset each other as much as possible the roundness and concentricity deviation of bias.

ways to improve fit

In order to improve the bearing manufacturer precision the actual installation, you must not make use of the bearing deformation measurement methods and measuring tools, bearings and cylindrical bore size of the mating surfaces of the actual precision measurement can be measured on the inner and outer diameters All items to be measured, and the measured data to make a comprehensive analysis of this as far and precision worthy of shaft and housing bore bearing mounting portion size. In actual measurements made ​​with the respective shaft and housing bore size and geometry should be the same with the measuring bearing temperature conditions.
To ensure the effect of a higher actual mating shaft and the bearing bore to match the surface, the roughness should be as small as possible.
In making these measurements, should be cylindrical and the bearing bore, the housing bore and the shaft, and a corresponding surface of the chamfered sides near the assembly, respectively, showing the maximum deviation to make the direction of two marks, so that in actual assembly, the mating alignment of both the maximum deviation of the same position, so that after assembly, the two sides can be partially offset by the deviation.
Directional signs made ​​two aims can compensate for deviations into account, even if both sides supporting each rotation accuracy improved, but also between the two bearing seat hole and both ends of the journal concentricity error partially eliminated . Surface hardening on the mating surfaces to implement measures, such as sandblasting, with a diameter slightly larger than the precision plunger plug holes, once inside, there is help to improve the fitting accuracy
