摘要
滚动轴承是电动机的易损件,针对各种影响其使用寿命的因素,根据滚动轴承的配置情况,并考虑摩擦力矩和轴的热膨胀影响,提出延长电动机滚动轴承使用寿命的措施,并加以论证。
Rolling bearing is a wearing part of motor.This paper presents and proves the measures to extend service life of rolling bearing of motor based on various factors which influence its service life such as bearing configuration,friction torque and thermal expansion of shaft.
