从理论上分析了润滑脂的失效机理及影响因素，指出温度、转速、载荷与填脂量是影响轴承润滑脂寿命的主要因素，通过模拟特定工况对某全合成锂皂润滑脂的润滑寿命进行了试验。结果表明：温度升高20℃，润滑脂的50％可靠度寿命降低约60％；转速增加50％，润滑脂可靠度寿命降低40％以上。
從理論上分析瞭潤滑脂的失效機理及影響因素，指齣溫度、轉速、載荷與填脂量是影響軸承潤滑脂壽命的主要因素，通過模擬特定工況對某全閤成鋰皂潤滑脂的潤滑壽命進行瞭試驗。結果錶明：溫度升高20℃，潤滑脂的50％可靠度壽命降低約60％；轉速增加50％，潤滑脂可靠度壽命降低40％以上。

The failure mechanism and influencing factors of grease are analyzed theoretically,it is pointed out that the temperature,rotational speed,load and filling grease amount is main factors affecting lubricating life of bearing grease. The test is carried out for lubricating life of synthetic complex lithium soap grease by simulating special working condi-tion.The results show that the 50% reliability life of lubricating grease reduces by about 60% when temperature rises by 20 ℃,and the life of lubricating grease reduces by more than 40% when rotational speed rises by 50%.
