Rolling - Structure

Rolling wheel bearing type, structure, size and accuracy class and so forth with the code represents. No special requirements for normal bearings, Chinese code with four Arabic numerals. The front one is a type code, followed by the diameter of the series code, the last two digits for the diameter size code. The bearings have the same diameter of several different diameter, of special light, light, medium and heavy series, respectively, with 1,2,3,4 expressed. Special light series, minimum diameter, heavy series OD Max. 20 to 459 mm diameter bearings, bore size code is bearing diameter by 5. For example 6308:6 represents angular contact ball bearings, three representatives of the series, 08 on behalf of the bearing inner diameter of 08 × 5 = 40 mm.
Bearing load and life of any one element appears before contact fatigue wear running total number of revolutions at a certain speed or the total number of hours worked, called the bearing life. Greatly varied life of rolling bearings, bearing the same batch of operating under the same conditions, its life can vary several times or even several times. Bearing the same batch of 90 percent before the fatigue spalling can meet or exceed the total number of revolutions (or working hours) when referred to the rated life L. Rated life of 1 million revolutions can bear the load of dynamic load rating C. Withstand the maximum load of the rolling element and raceway contact points and the amount of plastic deformation of the rolling element diameter reaches ten thousandth, can bear the load of static load rating C0. Rated load greater load bearing capacity of the stronger. Radial bearings rated load is a pure radial load, thrust bearing load is a pure axial load. Actual load bearing condition often associated with different rated load shall be converted into the equivalent load. In the equivalent dynamic load P under the action of bearing life and the actual life of the same load conditions. In the equivalent static load P0 under the action of the maximum load of the rolling element and raceway contact points with the total amount of plastic deformation under the actual load conditions the same. Bearing rating life, dynamic load and dynamic load equivalent relationship between

Toperfect Snyder help you analyze 'bearing common faults and their

Bearing, if no error can be properly selected to use, it can be used for a long time; the right choice of the proper use of the case, the damage state is releasable. On the other hand, there are accidental injuries and unable to withstand the early use of early damage; early as the cause of the damage, there is not enough to consider the use of lubrication, there is foreign invasion, and thus have bearing installation errors and shaft deflection, on the shaft and housing accuracy, materials research is not enough and so on. It can be said that these reasons overlap each situation is more common.
Roller wheel bearing fault phenomenon is generally expressed as two, one bearing installation site temperature, and second bearing operation in noise.
1, the bearing temperature
Running on the host, install the bearing parts allow a certain temperature, when stroking host shell, you should not feel hot to normal, otherwise indicates that the bearing temperature.
Bearing temperature causes are: oil quality does not meet the requirements or deterioration, lubricant viscosity is too high; Host assembly too tight (lack of space): Bearing assembly too tight; bearing ring on the shaft or housing rotating load is too large; bearing cage or rolling fragmentation.
2, the bearing noise
Rolling in the work allow slight noise, if the noise is too large or unusual noise or crash thump sound, it indicates that the bearing has failed.
Rolling noise is more complex reasons, one is the bearing inner and outer supporting surface wear. And such wear, damage to the bearings and the housing, the bearing and shaft supporting relationship, resulting in an axis deviation from the correct position, the bearing running when a load generation of abnormal noise. When the bearing fatigue, the surface metal flake; also make the bearing radial clearance increased abnormal sound. In addition, the lack of bearing lubrication, the formation of dry friction, and bearing broken, etc. will have an unusual sound. After Songkuang bearing wear, loose cage damaged, will produce abnormal noise.
The method of the fault
(1) replacement of bearings, to carefully examine the new bearings, while the shaft and bearing bore and the rotor careful examination;
(2) assembly and disassembly of the bearing, the strict implementation of the maintenance process, serious operation, to avoid bearing damage due to improper assembly and disassembly;
(3) time and fuel oil, ensure the bearing working conditions is always in good condition;
(4) the operation carefully checked and found hidden faults, timely elimination.
