Abstract

Abstract. Based on the space curve meshing equation, a novel helical gear mechanism with improved geometry is presented. First, equations of the theoretical contact curves were derived based on the space curve meshing theory. Then, tooth surfaces with a concave–convex meshing form were constructed, depending on the contact curves. The tooth profiles were improved as the theoretical contact curves were corrected by predestining the designed transmission errors. The effect of the center distance error on the transmission errors was studied, and the effects of gear modifications on transmission errors and maximum contact stresses were also investigated. The results show that the transmission error curves of the improved gear drive become much smoother. Maximum contact stresses of the improved gear drive are decreased synchronously.

一种改进了平行轴传动几何形状的新型斜齿轮机构的齿形设计

摘要基于空间曲线啮合方程，提出了一种改进几何形状的新型斜齿轮机构。首先，基于空间曲线啮合理论推导了理论接触曲线方程;然后，根据接触曲线，构建凹凸啮合形式的齿面;通过确定设计传动误差，修正理论接触曲线，改进齿形。研究了中心距误差对传动误差的影响，以及修齿对传动误差和最大接触应力的影响。结果表明，改进后的齿轮传动的传动误差曲线更加平滑。改进后的齿轮传动的最大接触应力同步降低。

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
