Adjusting bearing fitting allowance to improve assembly quality of electric machines
Mian Zhang · Guangdong Electric Power · 2000
The fitting precision of motor bearing is one of the main factors influencing the assembly quality of motors. On evaluating the original design of bearing housing and bearing retainer and analyzing the actual processing, the modification on dimensional tolerance of bearing housing and shaft bearing retainer is proposed to acquire ideal end-play. The effectiveness of the proposed method in improving the fitting precision and diminishing the noise of motors is validated in practice.
