圆柱蜗轮副的承载能力与蜗轮副齿面的失配方式和失配量密切相关。本文给出了失配蜗轮副齿面接触特性的计算方法,并在此基础上制定了控制齿面接触特性及对蜗轮滚刀的设计和安装参数进行优化综合的计算方法.按照本文所述方法设计的滚刀,不仅可以完全无除修磨蜗杆这一费工费时的旧工艺,得到具有良好的啮合特性和很低的误差敏感性的蜗轮副,还可以使滚刀在允许的重磨范围内使用时,除了接触区的宽度略有变化外,蜗轮副的运动平稳性和接触区位置基本保持不变.由于不修磨蜗杆,蜗轮副可以完全互换.
The bearing capacity of the cylindrical worm gear is closely related to the mismatch pattern and mismatch of the worm gear tooth flanks. In this paper, the mismatch calculation method of tooth contact surface of worm gear is given, and based on which, the contact characteristics of tooth surface control and the calculation method of optimizing and integrating the design and installation parameters of worm gear are developed. According to the method The design of the hob not only eliminates the laborious old process of grinding the worm, but also provides a worm gear with good meshing properties and low error sensitivity. It also allows the hob to move within the permitted resharpening range In use, except the width of the contact area changes slightly, the smooth movement of the worm gear and the position of the contact area remain basically unchanged, and the worm gear pair can be completely interchanged due to not grinding the worm.
