摘　　要：针对高速圆柱滚子轴承保持架在引导方式选用上存在分歧的问题,基于Adore建立了高速圆柱滚子轴承的仿真模型,分析了保持架在外引导和内引导方式下,滚子数量、径向游隙、保持架引导间隙和兜孔间隙对保持架打滑及运转稳定性的影响,并通过高速轴承打滑试验验证了仿真模型的可靠性。结果表明,在内圈旋转的情况下,内引导方式比外引导方式更有利于防止保持架打滑;内引导方式下,采用较小的轴承径向游隙和引导间隙可以降低保持架的打滑率,并提高其运转稳定性;兜孔间隙对保持架打滑几乎没有影响,但是随着兜孔间隙的增大,保持架运转稳定性变差。Aiming at the divergences in the selection of the guidance mode of the high-speed cylindrical roller bearing cage,a simulation model of the high-speed cylindrical roller bearing is established based on Adore.The effects of the number of rollers,radial clearance,cage guidance clearance and pocket hole clearance on cage slip rate and running stability are analyzed under the outer guidance mode and inner guidance mode,and the reliability of the simulation model is verified by the high-speed bearing slip test.The results show that when the inner ring rotates,the inner guidance mode is more beneficial than the outer guidance in preventing the cage from slipping.In the inner guidance mode,the smaller radial bearing clearance and guiding clearance can reduce the cage slip rate and improve the running stability.The pocket hole clearance has almost no effect on cage slip,but as the pocket hole clearance increases,the running stability of the cage becomes worse.
