This paper presents a new method to measure tootherror of small module gears.
进行测量，提出了一种在视觉三坐标测量机上测量小模数齿轮齿形误差的新方法。

High frequency noise of gears is mainly from tootherror and base pitch, and low frequency noise from accumulated errors of tooth spacing.
齿轮高频噪声产生的主要原因是齿形误差和基节偏差；低频噪声产生的主要原因是齿距积累误差。

Of all the gear frequency errors, the non-linear dynamic characteristics of gear tootherror, pressure angle error and sprial fluctuation error are compared with the results of the linear system.
