This study aims to uncover the influencing mechanism of the tilt angles of the cage pocket walls of the high-speed cylindrical roller bearing on the bearing skidding.,A novel cylindrical roller bearing with the beveled cage pockets was proposed. Using the Hertz contact theory and the elastohydrodynamic and hydrodynamic lubrication formulas, the contact models of the bearing were built. Using the multibody kinematics and the Newton–Euler dynamics theory, a dynamics model of the bearing was established. Using the Runge–Kutta integration method, the dynamics simulations and analysis of the bearing were performed.,The simulation results show that the effects of the tilt angles of the front and rear walls of the pocket on the bearing skidding are remarkable. Under a 5° tilt angle of the front wall of the pocket and a 10° tilt angle of the rear wall, the bearing skidding can be effectively decreased in the rotational speed range of 10,000-70,000 r/min.,In this paper, a novel cylindrical roller bearing with the beveled cage pockets was proposed; a dynamics model of the bearing was established; the influence mechanism of the tilt angles of the front and rear walls of the pocket on the bearing skidding was investigated, which can provide fundamental theory basis for optimizing the pocket.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-01-2020-0035/

带斜面保持架兜孔的高速圆柱滚子轴承打滑研究

本研究旨在揭示高速圆柱滚子轴承保持架兜孔壁倾角对轴承打滑的影响机制。提出一种新型带斜角保持架兜孔的圆柱滚子轴承。利用赫兹接触理论和弹性流体动力和流体动力润滑公式，建立了轴承的接触模型。利用多体运动学和牛顿-欧拉动力学理论，建立了轴承的动力学模型。采用Runge-Kutta积分法对轴承进行动力学仿真和分析，仿真结果表明，凹槽前后壁倾角对轴承打滑的影响显着。在口袋前壁5°倾斜角和后壁10°倾斜角下，在10,000-70,000 r/min的转速范围内可以有效减少轴承打滑。建立了轴承的动力学模型；研究了型腔前后壁倾斜角度对轴承打滑的影响机理，可为优化型腔提供基础理论依据，本文同行评议历史见：https:// publons.com/publon/10.1108/ILT-01-2020-0035/
