平面包络环面蜗杆精度的非接触光电检测方法

Research on the Non-contact Measurement Method of the Planar Enveloping Annular Worm

目前,对平面包络环面蜗杆通常采用传统的接触式测量方法,该方法的测量精度不高,容易造成测量元件和被测齿面的磨损或划伤。为了提高平面包络环面蜗杆的精度,根据其成形原理提出了基于CCD的平面包络环面蜗杆精度的非接触光电测量的检测方法,通过对实测螺旋齿面方程和理论螺旋齿面方程的比较得到平面包络环面蜗杆的制造误差。

The traditional contact measurement method of the planar enveloping worm has low measurement precision and it usual- ly wears or scratches the measuring components and the measured tooth surface. In order to improve the processing quality of planar enveloping annular worm, according to the principle of processing, a non-contact measurement method of the planar enveloping annu- lar worm was put forward based on CCD. By comparing the measured spiral tooth surface and standards spiral tooth surface, the manufacturing error of planar enveloping annular worm was calculated.
