一种新型螺旋锥齿轮研齿在线自动侧隙调整方法

摘要

Based on the lapping principle of spiral bevel gears and hypoid gears, this paper focuses on a new automatic backlash adjustment method for lapping process of spiral bevel gears, which includes on-line detection and measurement of backlash, automatic backlash control and software etc. The experimental results show that this on-line automatic backlash control method is efficient and stable in lapping process of spiral bevel gears and can improve gear surface finishing and reduce transmission noise apparently.%在螺旋锥齿轮数控研齿原理基础上,通过对双齿侧接触对滚的过程分析,推导了侧隙的计算以及侧隙调整公式,提出了一种新型的螺旋锥齿轮研齿在线自动侧隙检测和调整方法;设计开发了一套在线自动侧隙检测和调整研磨软件,通过线性插补可以进行各研磨点对应路径的侧隙在线自动调整.在数控研齿机YK2560上进行螺旋锥齿轮的研齿实验说明了该方法及其软件能高效、稳定地实现研齿加工,研齿后的螺旋锥齿轮副传动噪声大幅降低,研齿效果良好.
