基于响应面法的齿轮容差设计方法研究

随着附件传动系统不断向高速、重载方向发展,齿面接触可靠性问题越来越受关注.为提高齿轮可靠性,分析了齿轮传动系统常见误差类型及影响,开展了齿轮容差设计初步探讨.根据齿轮制造、加工及系统动态误差的产生原理和作用方式,基于齿轮接触应力仿真结果,确定了影响齿轮接触应力随机性的5种主要误差形式及其特征量分布规律,提出了基于响应面法的齿轮容差设计方法,给出了齿轮系统公差设计的改进方向:在进行齿轮公差设计时,重点控制H、V方向的轴向平行度公差.

Methods of Tolerance Design for Gears Based on Response Surface Methodology

With the accessory driving system takes the way towards the high speed and heavy load, the contact reliability of aviation gears make more sense. In order to improve the design reliability, the common error types and effects of gear driving system were analyzed, and the study of tolerance design was proposed. According to gear processing and manufacturing, the principle and action-mode of the systematic dynamic error, five main error types and their characteristics of the random error of the contact stress of the gear were determined on the basis of the simulation results. Moreover, a method of gear tolerance design based on response surface was proposed and the improvement direction of tolerance design of gear system was given: the tolerance for the direction of H and V should be mainly controlled during the tolerance design.
