摘要

RV减速器摆线针轮副的啮合间隙大小是影响其传动性能的关键因素,目前国内的研究多采用公式法来计算摆线针轮的初始啮合间隙,未考虑传动过程中节点位置的变化,导致理论结果与实际啮合间隙存在差异。提出将实际齿廓公法线方向的齿廓间距离作为精确啮合间隙,通过对传统初始啮合间隙计算方法的深入分析,建立摆线针轮齿面接触模型,计算出任意转角下精确啮合间隙的大小,为RV减速器摆线针轮副啮合间隙的计算和分析提供理论基础。

Abstract

The meshing backlash of cycloidal-pin wheel drive in RV reducer is the key factor that affects the transmission performance. At present,the formula method is adopted mainly to calculate the initial meshing backlash of cycloidal-pin wheel. But there are some differences between the theoretical result and the actual value because the formula method did not consider the change of node position in the process of drive. Taking the distance between the profiles in the direction of the common normal as the accurate meshing backlash is proposed. The traditional initial meshing backlash calculation method is analyzed and the tooth contact model of cycloidal-pin wheel is established,then the accurate meshing backlash at any angle is obtained. A theoretical basis for calculating and analyzing the exact meshing backlash of cycloidal-pin wheel drive in RV reducer is provided.
