概述现有的圆弧齿轮强度计算,接触强度常常沿用赫芝公式再按实践经验修正某些参数;弯曲强度则按无限宽的悬梁受集中力为基础,再计入曲率半径的影响系数。本文根据瞬时接触区宽度(它由当量曲率半径
The existing strength calculation of arc gear is summarized. The contact strength is often modified according to the Hechi formula and then some parameters are corrected according to practical experience. The bending strength is based on the concentration force of the beam with infinite width, then the influence coefficient of curvature radius is taken into account. This article is based on the instantaneous contact area width (which is defined by the equivalent radius of curvature
