Abstract

The roller profile shape can change the fatigue life and vibrations for planet roller bearing (PRB), as well as the impact between the rollers and cage. In this study, an analytical study of the dynamic forces and vibrations of a PRB considering the roller profile. To avoid the stress concentration at the roller ends, the roller modification method is proposed to improve the dynamic forces. The contact stiffness and load-deformation exponent of the roller-race interaction for four different roller modification types are achieved. A PRB dynamic model is established to discuss the effects of roller modification types on the dynamic forces and vibrations for PRB. Computation results of those four roller modification types are compared to the results of the PRB with the cylindrical roller type. It includes that the roller profile shape can greatly change the contact forces between the rollers and races, as well as the impact forces between the rollers and cage. The roller profile shapes can also influence the vibrations of PRBs.

考虑滚子齿形的行星齿轮滚子轴承动力与振动仿真方法

行星滚子轴承(PRB)的滚子轮廓形状可以改变其疲劳寿命和振动，以及滚子与保持架之间的冲击。在这项研究中，分析了考虑滚子轮廓的PRB的动力和振动。为避免滚轮端部应力集中，提出了改进滚轮的方法来提高动态力。得到了四种不同修形方式下滚子-滚道相互作用的接触刚度和载荷-变形指数。建立了PRB的动力学模型，讨论了轧辊修改类型对PRB动力和振动的影响。将这四种辊型的计算结果与圆柱辊型PRB的计算结果进行了比较。它包括滚子轮廓形状可以极大地改变滚子与套圈之间的接触力，以及滚子与保持架之间的冲击力。辊型形状也会影响PRBs的振动。

期刊介绍： The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice. "Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications."
