Abstract

This paper delves into the generation of helical face gears using a grinding worm. It investigates the computerized generation process and explores the inherent geometric constraints associated with the application of a grinding worm for helical face gears. An approximate grinding method, tailored for helical face gears featuring large helix angles, is proposed, with an evaluation of the resulting theoretical deviations. Furthermore, a novel rapid computational approach for determining the bearing contact of helical face gear pairs is introduced and validated through Finite Element Analysis (FEA). The subsequent analysis comprehensively examines the effects of the machine tool positioning errors on tooth flank deviations, bearing contact, and transmission errors. A sensitivity matrix is developed to elucidate the relationship between machine tool positioning errors and the tooth flank deviations, leading to the proposition of a correction method for theoretical generating deviations. Finally, the paper introduces a tooth flank modification method for helical face gears and the meshing performance is highly improved.

螺旋齿面齿轮的计算机生成、偏差修正和快速齿面接触分析

本文深入探讨了使用磨削蜗杆生成斜面齿轮的问题。它研究了计算机生成过程，并探讨了与螺旋面齿轮磨削蜗杆应用相关的固有几何限制。针对螺旋角较大的斜面齿轮提出了一种近似磨削方法，并对由此产生的理论偏差进行了评估。此外，还介绍了一种新的快速计算方法，用于确定斜面齿轮对的轴承接触情况，并通过有限元分析（FEA）进行了验证。随后的分析全面考察了机床定位误差对齿面偏差、轴承接触和传动误差的影响。通过灵敏度矩阵阐明了机床定位误差与齿面偏差之间的关系，从而提出了理论偏差的修正方法。最后，论文介绍了斜面齿轮的齿面修正方法，啮合性能得到极大改善。
