摘要
主要介绍了工作基准面与水平面成一定倾斜角度的大中型绕线式电机,在电机非轴伸端增加背靠背安装的角接触球轴承,用于承受电机倾斜产生的径向力,并对转子轴向定位,从而保证滑动轴承的正常运行。
This paper chiefly introduces large- and medium-sized wound-rotor motor with a certain tilt angle between working base plane and horizontal plane. The angular contact ball bearing installed back-to-back is added on non-shaft extension end of motor to bear radial force caused by motor tilt and axially fix rotor. It can ensure normal operation of sleeve bearing.
