Variation rule of wear-resistance property and coefficient of friction were investigated by testing for wear mass loss and moment of friction under different parameter condition. 通過測(cè)定失重量和摩擦力矩的波動(dòng)情況，得出了在不同的工藝參數(shù)條件下試樣的抗磨損性和摩擦因數(shù)的變化規(guī)律。
The moment of friction of high-speed grease-lubricated rolling bearing determines its power consumption and heat output, and the heat output has a direct effect on its temperature rise. 在高速脂潤滑滾動(dòng)軸承中，摩擦力矩的大小決定了軸承的功率消耗和發(fā)熱量的大小，發(fā)熱量的大小直接影響軸承的溫升失效。
Friction moment of rolling bearings belongs to a poor information system where both probability distribution and trend are unknown, with having uncertain change of fluctuating and trend. 滾動(dòng)軸承摩擦力矩具有不確定的波動(dòng)和趨勢(shì)變化，屬于概率分布與趨勢(shì)規(guī)律都未知的乏信息系統(tǒng)。
