三相异步电机装配轴承异音分析

Research on Assembly of Three-Phase Asynchronous Motor and Abnormal Noise of Bearing

针对三相异步电机装配过程中出现的轴承异音现象,提出了一种辅助卧式装配的工艺方法。该方法通过固定转子与端盖的平衡度,控制传动端滚柱轴承与轴承内圈的相对倾斜运动,可有效避免轴承异音的产生,从而提高电机装配合格率,降低检修时长,节约生产成本。

Aiming at the phenomenon of abnormal noise of bearing in the assembly process of three-phase asynchronous motors,this paper puts forward a horizontal auxiliary assembly process method.By fixing the balance between the rotor and the end cover,the relative tilt motion between the rolling bearing at the transmission end and the inner ring of the bearing is controlled,so as to effectively avoid bearing abnormal sound,that is,the process can effectively improve the motor assembly qualification rate,reduce the maintenance time and save production cost.
