The loading device for an oversize rotating disk bearing performance testing machine can apply radial force to the bearing so as to simulate applied disturbing moment.
Description
Technical field
The utility model relates to a kind of bearing performance testing machine, and particularly a kind of bearing outside diameter is that the super-huge turntable bearing performance aircraft of φ 1600-φ 3500mm is used charger.
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, bigger with the external product gap.Along with the aggravation of wind energy market competition, reliability of products is required all the more strictness, main engine plants have proposed more and more stricter requirement to wind energy Production of bearing merchant, do not have research technique, with the approval and the market access that are difficult to obtain the user.Even we have solved 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.And product in case in the user uses, lost efficacy will give manufacturer in reputation with bring about great losses economically, and this risk is that any Production of bearing factory is difficult to accept.For the test of extra large size bearing, because the external main manufacturing enterprise of the importance of bearing all quite payes attention to, in order to guarantee reliability of products, the huge fund of all not stinting is carried out simulation test through the whole bag of tricks to its product.Through test well designed, improvement technology, make its product reach quite high technical merit and reliability.But because such testing machine belongs to the crucial specialized equipment of super-huge turntable bearing development, external bearing producer is to this testing machine blockade on new techniques, and domestic production producer lacks corresponding test condition.Because especially big property bearing tester complex structure, the investment bigger; Domestic also do not have a Related product, has only some producers to make some brief test devices, owing to can not simulate the bearing operating mode; The detection of turning quality can only be done, checking effect can't be played product.The device that in testing machine, test bearing is applied radial force is very important device.Through oil cylinder maximum to a certain amount of radial force is added on the loading arm, thus the disturbing moment that simulation applies.
Summary of the invention
The purpose of the utility model provides a kind of super-huge turntable bearing performance aircraft and uses charger, applies radial force through it to bearing, thus the disturbing moment that simulation applies.
The purpose of the utility model can realize through following technical scheme; Described charger comprises transition disc, loading arm, self-aligning roller bearing and load cylinder; Transition disc is connected with the left end of loading arm; Through bolted on connection, test bearing encloses surely through bolt and work top and connects between transition disc and the test bearing moving-coil, and self-aligning roller bearing is arranged on the right-hand member of loading arm; The self-aligning roller bearing bottom links to each other with load cylinder, and the pressurization oil cylinder is connected with hydraulic loaded control device on the testing machine.Through oil cylinder maximum to a certain amount of radial force is added on the loading arm, thus the disturbing moment that simulation applies.
[0005]The utility model is through applying radial force to bearing, thus the disturbing moment that simulation applies.Adopt self-aligning roller bearing to make loading arm under the situation of pressurizing and deformation, can adjust automatically.The amount of overcoming that acts on the test bearing when lengthening makes applied voltage test as far as possible owing to loading arm reduces, and reduces the influence of the moment of friction of test bearing generation to test findings as far as possible.Adopt computing machine complete monitoring and image data, with the dual output of mode of numeral and figure, the test process automation degree is high.Data through computer acquisition, processing are accurate, reliable, avoided the influence of artificial factor, and the loading curve of output and moment of friction curve are quite directly perceived.
After loading radial force, can measure by the starting friction moment and the spin friction moment values of examination bearing through torque sensor, and can detect real-time current value.Process is to the test of the various working of bearing; Draw a series of test figure; Need make measured axis after test finishes and tear the cover detection open; Thereby can draw after the actual loaded axial force influence, thereby certain test figure is provided, reference frame effectively is provided the design and the manufacturing of bearing to raceway, retainer, roller.
