中心高160及以上的4、6、8极Y系列电机轴伸端用短圆柱滚子轴承时,电机的轴向振动问题没有用球轴承时那样突出,但柱轴承多伴有“咕噜”异常声,当填加润滑脂后,这种异常声消失,6、8极电机甚至有相当多规格的大多数电机可以达到噪声的1级水平。由于装配过程中柱轴承的外圈是可以分离的,正常装配时轴承的滚子及沟道之间不会受到撞击力,损伤的机会要少得多,而球轴承则不然,装配时沟道、钢球处于受力状
Center high 160 and above 4,6,8 pole Y series motor shaft end with short cylindrical roller bearings, the motor axial vibration problem is not as prominent with the ball bearings, but more with the cylinder bearing “grunt” abnormalities Sound, when filled with grease, this anomalous sound disappeared, 6,8 pole motor even a considerable number of specifications of most motors can reach level 1 noise. Since the outer ring of the column bearing can be separated during the assembly process, the roller and the channel of the bearing are not affected by the impact force during normal assembly, the chances of damage are much less and the ball bearings are not. , The ball is in force
