为了降低中小型电机的整机的振动和噪声,必须严格控制所使用的滚动轴承的质量。实践证明,选用低噪声的滚动轴承可明显地降低整机的噪声水平。本市电机行业中一般用大连市生产的S 0910轴承测试仪来测试滚动轴承的振动分贝值,从而判断轴承的质量。但该机只能测试内径φ60mm以内的向心推力球轴承。我厂有相当批量的电机采用内径φ60mm以上的滚动轴承,其中有部分还是滚柱轴 In order to reduce the vibration and noise of the small and medium-sized motor, the quality of the rolling bearing used must be strictly controlled. Practice has proved that the choice of low-noise rolling bearings can significantly reduce the noise level of the machine. The city of motor industry in general use of S0910 bearing tester produced in Dalian to test the vibration decibel rolling bearing values ​​to determine the quality of bearings. But the machine can only test the inner diameter φ60mm to the thrust ball bearings. I have a considerable amount of motor plant with a diameter φ60mm above the rolling bearings, some of which are roller axis
