Bearing test method - bearing knowledge both at home and abroad

At present, the main bearing test method, there are four: first, friction and wear test, (2) test bench test, (3) laboratory ( Proving ground) Simulation test, four operation test, the actual working condition. Overseas for the above several test methods were used, but different application purpose, for example, to develop a new product, must first do friction and wear test. But if the friction wear form without much change, only change product size, loading conditions, are only do the bench, or actual operation simulation test. Overseas for some of the key parts of the new product ( Such as car wheel hub bearing, etc. ) Practice test, the inspection is very strict, must to be allowed. Swedish SKF bearing, Japan NTN bearing new research bearing simulation test, simulation technology, only alternative test bench or experiments, so as to shorten the time of product design, speed up the progress of product development, but from the actual operation situation and the gap. Now, China's bearing industry has to carry out the friction and wear test, only a luoyang bearing research institute; Has carried out bearing test bench, the shaft developed by luoyang bearing research institute, Shanghai, hangzhou bearing test center and wafangdian, Harbin and so on more than 20 bearing state-owned enterprises; Can expand the simulation test of luoyang bearing research institute, hangzhou bearing test center and luoyang, shaft, and other enterprises. Rather than the actual test, only in the aspect of supporting the host enterprises put forward the bearing production enterprises shall, when required, such as wheel bearings of railway passenger cars and car wheel hub bearing, etc. All in all, the domestic in the aspect of simulation and practical operation tests is not wide, should further expand the host range or scope of actual working condition, simulation test for the early schedule ready for the full hardware and software.
