滚动轴承的损伤,表现为磨耗、烧损以及轴承材料的疲劳,滚动面的润滑状态也将对其产生一定影响。本文根据在正常脂润滑状况下材料疲劳的轴承寿命近况以及由于疲劳而发生损伤时的特征,包括过去的一些实验事例,进一步介绍日本产电动机用滚动轴承寿命的进展情况。 Rolling bearing damage, manifested as wear and tear, as well as bearing material fatigue, rolling surface lubrication state will also have some impact. In this paper, based on the status of the bearing life of the material under normal grease lubrication, as well as the characteristics of the damage due to fatigue, including some experimental cases in the past, the progress of the life of the Japanese-made motor rolling bearing is further introduced.
