摘要

提出了一种新型的渐开线离散球齿轮传动机构,该机构能实现在空间中的俯仰、偏摆及回转运动的传动,同时避免了现有离散球齿轮存在的传动原理误差。使用ANSYS仿真软件对分度圆直径为512 mm的渐开线离散球齿轮于不同啮合状态的齿面接触特性进行分析,发现在定转矩下渐开线离散球齿轮啮合传动的齿面接触面积与啮合角的变化成反比;且当啮合角变大时,最大接触应力作用点将移向齿顶,同时最大接触应力也随之增大,可达2.059 3×10,6,MPa,通过该种齿轮传动特性的研究为空间传动机构、机械臂等研究提供应用依据。

Abstract

A new kind of the discrete involute spherical gear transmission mechanism is presented,this gear transmission mechanism can realize the transmission of the pitch motion,partial pendulum movement and rotary motion in the space and avoid the transmission principle error of the existing discrete spherical gear. By using the ANSYS simulation software,the tooth surface contact characteristic analysis of the discrete involute spherical gear with dividing circle diameter is 512 mm under different meshing states is carried out. It is found that,the tooth surface contact area of the discrete involute spherical gear transmission is inversely proportional with the change of meshing angle under the condition of fixed torque. And along with the meshing angle increases,the maximum contact stress action point will move toward the tip,and the maximum contact stress will increase（ up to 2. 059 3 × 10,6,MPa）. Through studying the transmission characteristics of this kind of gear,the basis of application for the study of spatial mechanism and mechanical arm is provided.
