Spray) apart from bearing seal surface 70mm, injection direction is vertical with test bearing end face or in 45 °, jet hole diameter 3mm, spray
After amount of jet 3.5L/min, test bearing empty wagons 0.5h, direct-injection 1h, then tiltedly spray 1h, carry out circulation 3 times, go round and begin again by set
Test on ground；
(4) resist and wipe the mud that test bearing sample surfaces adhere to totally with the lubricating grease spilt after splashing performance test,
And by bearing samples weighing, vibration measuring is dynamic, surveys end-play, running accuracy, staring torque, with specific purpose tool by test bearing sample
Sealing ring dismantle, uniformly take lubricating grease sample from its both ends respectively；
(5) detected from the lubricating grease of step (4) sampling, judge test bearing meets which following feature：
A, any feature entered without mud；
B, color with oil color or density have slight change because entering mud；
C, color with oil color or density have obvious change because entering mud；
D, there is sign existing for small mud, and there is color with oil color or density to have slight change because entering mud；
E, with the presence of big drop mud or substantial amounts of moisture, and color with oil color or density have slight change because entering mud.
Further, the balance range of weighing and precision that the step (1) uses should be able to meet test requirements document, measurement accuracy
For 0.01g, and periodic verification, and test bearing sample claims its to try fore bearing sample quality before upper machine is tested.
Further, the anti-performance aircraft that splashes of step (3) middle (center) bearing should meet the anti-requirement for splashing performance test parameter,
Anti- performance test parameter of splashing splashes performance test rotating speed and test load including anti-.
Further, the test bearing peeling area of step (5) detection is less than 5mm2, sealing ring remain to keep sealing
Function, without noticeable wear and deformation, and mud is qualified bearing into compliance with a and b two.
Compared with prior art, have the advantages that：
The present invention can detect the performance and outward appearance holding capacity of bearing resistance liquid medium, and the problem of existing to bearing can
To understand in time, production technology can be adjusted in time, preferably ensure the quality of bearing.
