摘要

提出了一种新型多圆弧齿廓齿轮的几何设计方案

该设计解决了公切线式双圆弧齿轮非工作面接触问题。并且这种新型齿廓较双圆弧齿廓增加了一个啮合点。根据此方案

设计出法面相切式四圆弧齿轮基本齿廓

给出相切式四圆弧基本齿廓参数的计算方法。提出了公切线式双圆弧齿廓以及相切式四圆弧齿廓非工作面间隙的近似计算方法

同时提出了非工作面不发生接触的判别标准

并加以验证。与分阶式设计相比

公切线式设计方案由于齿廓上不存在尖点因而适于数控成形硬齿面磨削。

Abstract

The design of basic rack tooth profile of tangent quadruple circular-arc gear means to the problem that non-working surface of tangent double-arc gear contact is proposed.Moreover

the tangent quadruple circular-arc gear has one simultaneous meshing point more than double-arc gear.Based on the geometrical analysis of the design

the parameters of basic rack tooth profile of tangent quadruple-arc gear are calculated.Then

the way to calculate the gap of the non-working surface of tangent calculate double-arc gear or of tangent quadruple circular-arc gear and the criterion whether non-working surface contacts are proposed and proven.Without cusp

the design of basic rack tooth profile of tangent quadruple circular-arc gear adapt to being processed by CNC gear form grinding tool.
