摘要

提出了一种新型齿轮——双向弧线圆柱齿轮,该齿轮齿线为圆弧,增加了齿轮的抗弯强度,消除了齿轮传动的轴向力;齿轮在啮合过程中,其接触为凸曲面与凹曲面的接触传动,增加了齿轮的承载能力,降低了齿面的磨损,提高了齿轮的寿命。重点对该齿轮副的啮合特性进行研究,推导出了其轮廓曲线方程、齿面方程和传动比。得出该齿轮副具有传动比恒定、传动平稳的优点。

Abstract

A new type of gear bi- directional arc cylindrical gear is proposed,the tooth trace of the gear is arc,the bending resistance strength of the gear can be increased and the axial force of the gear transmission can be eliminated. In the processes of gear transmission meshing,it is convex surface and concave surface contact transmission,the carrying capacity of the gear is increased,the wear of the tooth surface is decreased,the service life of the gear is improved. The gear pair meshing character is researched and its contour curve equation,meshing line equation and transmission ratio are derived. reach A conclusion that the gear pair possess the advantages of constant transmission ratio and stable transmission is obtained.
