Experimental Study on the Anti-wear Performance of Lubricating Greases
In the paper,the anti-wear performance of lubricating greases was investigated using the four-ball method,taking into consideration the current application of lubricating greases in vehicle driving.With reference to SH/T 0204,the anti-wear performance of four types of lubricating greases was studied by controlling the parameters of external load,tem-perature,time,and rotational speed tests.The test results showed that the diameter of the wear scar of lubricating greases was positively correlated with load,temperature and time,while it showed no significant variation with rotational speed(normal driving),low-speed and high-load(climbing),and high-speed low-load(high-speed operating conditions).
