Description
Technical field
The invention belongs to a kind of bearing performance test machine, the oversize rotating disk bearing performance testing machine that particularly a kind of bearing outside diameter is φ 1600-φ 3500mm.
Background technology
Adjustment along with China's energy structure, wind-power electricity generation occupies more and more important share as a kind of clean energy resource, huge the increasing in wind energy bearing market as large-scale turntable bearing, but because domestic production producer lacks corresponding test condition, can't do further improvement and raising to bearing performance, larger with the external product gap.Along with the aggravation of wind energy market competition, all the more strict to the reliability requirement of product, main engine plants have proposed more and more stricter requirement to wind energy Production of bearing business, there is no research technique, will be difficult to obtain user's approval and the market access.Even we have solved the problems such as product design, process equipment, processing technology measurement, the user also is difficult to accept not pass through the product of verification experimental verification.Once and product in the user uses, lost efficacy will be to manufacturer in reputation with bring about great losses economically, this risk is that any Production of bearing factory is difficult to acceptance.For the test of extra large size bearing, due to the importance of bearing, external main manufacturing enterprise all quite payes attention to, and in order to guarantee the reliability of product, the huge fund of all not stinting is carried out simulation test by the whole bag of tricks to its product.By the test well designed, improve technique, its product is reached quite high technical merit and reliability.But because such testing machine belongs to the crucial specialized equipment that super-huge turntable bearing is developed, abroad bearing producer is to this testing machine blockade on new techniques, and domestic production producer lacks corresponding test condition.Due to especially big property bearing tester complex structure, the investment larger, domestic also do not have a Related product, only has some producers to manufacture some brief test devices, owing to can not the bearing operating mode being simulated, the detection of turning quality can only be done, the checking effect to product can't be played.
summary of the invention
The purpose of this invention is to provide a kind of oversize rotating disk bearing performance testing machine, instant moment of friction value in the time of can measuring the starting friction moment of tested bearing after loading radial pressure and rotation status by the hydraulic loaded mode, and the stationarity of the running of observation bearing in loading procedure.
