随动控制系统下的齿轮螺旋线拟合方法研究

Research of the gear spiral fitting method under the servo control system

设计了随动控制型齿轮测量系统齿轮误差计算模型。利用随动控制系统作为测量齿轮螺旋线偏差的控制方式,以被测齿轮的螺旋线偏差为研究对象;对被测齿轮的实际螺旋线建立分析模型,对其跟踪轨迹进行螺旋线拟合,并实现螺旋线偏差的计算。本模型能够在简化系统运动控制方式和结构情况下,有效地测量齿轮螺旋线误差,并对建立的分析模型的准确性进行了验证。

Designed servo-controlled gear measuring system of calculate gear error model. Use the servo control system to measure gear spiral deviation as the control method, and study the spiral deviation of the measured gear, establish model on the actual measured gear spiral, fitting the tracking trajectory. It can simplify the structure of motion control and the circumstances, effectively measure the gear helix error and the accuracy of established model was verified
