The performance data of lubricating grease in the embodiment of the present invention 1~3 of table 1
Wherein, the method for testing of wear extent is as follows：
Lubricating grease SRV (face contact) wear extent method of testing
Method：See the lubricating grease friction and wear behavior test method(s)s of SH/T 0721 (high frequency linearity vibration rig method)；
Condition：Normal temperature, 10h, 50Hz, 1.0mm, 400N, face contact；
Testpieces specification：Test board：See SH/T 0,721 7.2；
Proving ring：52100 steel, hardness RC are 60 ± 2, and roughness is identical with test board, external diameter 20mm, internal diameter 17mm, high Spend 5.5mm.
Method is summarized：1. by the requirement of SH/T0721 methods by test board and proving ring wiped clean, and dried with dry silk, Weigh；
2nd, friction test is carried out after testpieces being smeared into lubricating grease by the experimental conditions of SH/T 0721 and step；
3rd, after off-test, lubricating grease unnecessary on testpieces is washed with solvent, and is dried with dry silk, is weighed.
4th, the difference of former and later two testpieces weight and as wear extent are tested.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
