近几年来,十分重视滚动轴承振动的研究。文献〔1〕中通过对1176724Б2球轴承保持架振动频率的理论研究和试验分析,对谐振时轴承的应力进行测定,证明了为保证轴承工作可靠,必须排除保持架的谐振或者限制其振幅,并断定:低振动频率(f=155Hz时)最危险,保持架中的应力可达到200MPa。为减小应力,建议缩小游隙。文献〔2〕中研究了径向止推球轴承1176724Б2、1176724Б3保持架的振动,证明了保持架的自振频率在其工作频率范围之内。所以谐振
In recent years, great attention has been paid to the research of rolling bearing vibration. The literature [1] in the 1176724Б2 ball bearing cage vibration frequency through theoretical research and experimental analysis of the resonance bearing stress measured to prove that in order to ensure the bearing work reliably, you must rule out the cage resonance or limit the amplitude and Determine: the most dangerous low vibration frequency (f = 155Hz), the cage can reach the stress of 200MPa. To reduce the stress, it is recommended to reduce clearance. The literature [2] studied the radial thrust ball bearings 1176724Б2, 1176724 B3 cage vibration, proved that the natural frequency of the cage within its operating frequency range. So resonant
