    想知道滑动轴承选用吗 想知道滑动轴承选用吗


        Sliding bearing radial load ability is considerably more than the calculated value, but allow rotation speed, and the speed of the motor are few actual, caused the bearing can not reach the rated service life. But import medium motor load side bearings are generally choose larger "light ball bearing", and is no-load side chooses load side of the small than "light roller bearings", such not only ensure the bearing carrying capacity, and bearing allows speed considerably more than the actual motor speed, so can reach or exceed the service life of sliding bearings. According to our motor sliding bearing of the analysis and calculation think, sliding bearing fault and the selection of sliding bearings has the very big relations. From our own motor to import of motor is to see, domestic medium-sized motor bearing load side, the general is to choose "medium roller bearings".


        滑动轴承的径向承载能力是大大超过了计算值,但是允许转速则与电机实际的转速相差很少,造成了轴承达不到额定的使用寿命。但是进口中型电动机负荷侧的轴承一般是选用较大的“轻型滚珠轴承”,而空载侧则是选用比负荷侧小的“轻型滚子轴承”,这样不但保证了轴承的承载能力,而且轴承的允许转速大大超过了电机的实际转速,所以能达到或超过滑动轴承的使用寿命。根据我们对电机滑动轴承的分析和计算认为,滑动轴承的故障与滑动轴承的选用有着很大的关系。从我国的电机与进口的电机比较来看,国产中型电动机的负荷侧轴承,一般是选用“中型滚子轴承”。
