本文介绍了面齿轮轮齿在分布载荷作用下的应力分析。通过几何分析，从啮合齿面之间的初始失配确定分布载荷。采用一种新的整体局部有限元法进行分析。在全局局部有限元法中，分析域被分成两部分;全局域和局部域，在全局域中，场由源自经典弹性理论的分析解定义，在局部域中，场由有限元解定义。此外，齿面膜单元，使齿面上的边界条件，以容易地表示，作为整体域。计算是针对具有各种不对中的面齿轮副进行的。对平面齿轮进行了沿着导程的凸度修形，并讨论了修形对面齿轮轮齿应力分布的影响。因此，接触应力和弯曲应力都不是很大。当有一些错位，只有接触应力增加。然而，小齿轮齿上的冠部对减小接触应力是有效的。此外，具有线性轮廓的面齿轮;即，近似的轮廓，也进行了讨论。然后，确认该轮廓是良好的近似。版权所有© 2003，ASME
The present paper describes a stress analysis of a face gear tooth subject to a distributed load. The distributed load was determined from an initial mismatch between meshing tooth flanks through geometrical analysis. A new global local finite element method was used for the analysis. In the global local finite element method, an analytical domain is divided into two parts; a global domain in which fields are defined by an analytical solution derived from a classical elastic theory, and a local domain in which fields defined by a finite element solution. Furthermore, tooth flank film elements, which enable boundary conditions on tooth flanks to be easily represented, are taken as the global domain. The calculations were performed for face gear pairs with various misalignments. Crowning modifications along lead were given to pinions, and the effect of the modifications on tooth stress distribution in a face gear tooth was discussed. As a result, both contact and bending stresses were not so large. When there are some misalignments, only contact stress increased. However, the crowning on a pinion tooth was effective for the reduction of the contact stress. Furthermore, face gear with linear profiles; i.e., approximated profiles, were also discussed. Then, it was confirmed that this profile is good approximation.Copyright © 2003 by ASME
