摘要

提出了一种非对称纯滚动齿轮的计算机化设计方法和利用横向齿廓内旋转主动设计传动误差卸载函数的新方法。建立了非对称纯滚动圆柱齿轮齿面参数化方程。对比分析了法向压力角和螺旋角的不同设计组合，重点分析了接触模式、传动误差、最大接触应力和弯曲应力。确定了最优的设计组合，并与不同法向压力角的对称纯滚动齿轮进行了比较，结果表明该齿轮具有较好的啮合特性和力学性能。此外，该方法基于横向齿廓的内旋转，可以实现传动误差卸载函数的抛物线曲线。通过样机的实验运动学试验，验证了非对称纯滚动齿轮设计的有效性。

Computerized design of asymmetric pure rolling gears with a method for predesigning the desired function of unloaded transmission errors

A computerized design method for asymmetric pure rolling gears and a novel approach for actively design the unloaded function of transmission errors using the internal rotation of the transverse tooth profiles are proposed. Parameterized equations for the tooth surfaces of asymmetric pure rolling cylindrical gears are developed. A comparative analysis of various design combinations of normal pressure angles and helix angles is conducted, focusing on contact patterns, transmission errors, and maximum contact and bending stresses. The optimal design combination is identified and compared to symmetric pure rolling gears with varying normal pressure angles, demonstrating superior meshing characteristics and mechanical performance. Additionally, the proposed method, based on the internal rotation of the transverse tooth profiles, enables the achievement of a parabolic curve for the unloaded function of transmission errors. The effectiveness of the asymmetric pure rolling gear design is validated through an experimental kinematic test of the prototype.
