Timely maintenance of linear vibrating screen bearings to avoid heat damage
Linear vibrating screen is to use centrifugal force to drive the screen surface produce a certain frequency and amplitude of the movement, prompting the screen surface material for continuous, uniform jumps in constant contact with the screen to achieve coarse grained material grading screening effect. In linear vibrating screen work, there will be wind turbine earing shaker speed slows down, bearing the phenomenon of excessive temperature rise, promptly after the discovery of downtime caused by equipment failure that could cause investigation, repair, ensuring stable operation vibrating screen efficient.
Linear shaker exciter driven eccentric block symmetric structure of high-speed operation, when the device after prolonged use eccentric block off or eccentric block size is inconsistent, it will cause the device to speed exception. This time to the timely replacement of eccentric structure to ensure that the two biased linear vibrating screen blocks the same size, running balance. Linear vibrating screen bearings abnormal speed after prone to friction and temperature rise. When linear vibrating screen bearings lack of lubrication agent or lubricant agent added does not meet the equipment needs, resulting in linear shaker labyrinth seal device gridlock, the cause of bearing structure temperature exceeds the specified range values, this time to promptly inspect equipment lubrication system to ensure adequate cleaning lubricant agent, if found clogging will have to remove the bearing thorough cleaning; ring if damaged or worn bearings after fracture phenomena, to timely replace seals and bearings, re-adjust the line shaker again. Vibration sieve. New beginning screening material grading work.

TIMKEN bearing quality for temperature and vibration
Kunshan Bearing: Under normal circumstances, are factory brand TIMKEN bearings have their own dedicated designer of external packaging design, production conditions and arrangements for making the production of the factory clearance, so in terms of packaging lines to color are very clear, unambiguous, some brands of accessories package also devoted to the protection of their intellectual property unique design.
The bearing body will be printed with the brand words, labels and so on. Font is very small, but most are factory produced using Seal technology, but without the heat-treatment is carried out before the word pressure, so the font was small, but a deep concave, very clear. The font counterfeit products not only blurred, because the rough printing technology, fonts floating on the surface, and some can even be easily wiped off by hand.
Left hand holding the bearing sleeve bearing the body, right hand to rotate toggle coat, listen to whether there is a hybrid ring. As most of the counterfeit products behind the production conditions, completely hand-mill operation in the production process will inevitably distracted sand a class of impurities, TIMKEN bearings hidden in the body, so the rotation will be issued when hybrid ring. This is strictly enforced and production standards, and with the machine operation is the biggest difference between brands.
Bearing this in the purchase should pay special attention. Because of the current anti-rust technology is not particularly home, so the bearing body rust treatment can easily leave traces of oil thick, sticky thick stick in your hand, while the foreign original wind turbine earing almost invisible rust oil traces, it touches especially careful expert said bearing smells kind of taste, is certainly under anti-rust oil, but do not see it.
TIMKEN bearings called chamfer, which is horizontal plane and the vertical plane of the junction, counterfeit bearings due to production technical limitations in these corners of the site handled unsatisfactory.
Vibration of the bearing damage can be quite sensitive, peeling, creasing, corrosion, cracks, wear, etc. will be in the bearing vibration measurement reflected. So, by using a special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, frequency points can not be inferred abnormal circumstances. The measured values due to the conditions of use or the bearing sensor mounting location is different, so each machine needs prior to analysis and comparison of the measured values determined criteria.
