The spiral bevel gears, which have little noise, are suitable for high speed running. These gears are widely used for automobiles, helicopters, etc. Recently, as the precision of this gear required become more and more high standard, the process of three-dimensional tooth surface correction by an NC lapping machine is carried out after heat treatment. On the other hands, gear noise is evaluated by various measuring method, and generally the value at mesh frequency is paid attention. However, recently the sideband wave of the mesh frequency have been beginning to be evaluated to confirm an accuracy dispersion of each tooth in a gear. But there are few papers dealing with the sideband wave. Then, we pay attention to the side bands of mesh frequency, such as the Oerlikon-type which has been considered the high of the cutting efficiency. Then, the mechanism of side bands was clarified by supposing that was generated amplitude modulation and frequency modulation. On the other hands, a simplified measurement method of pitch errors was proposed. And relation sideband wave of rotational vibration of gear and pitch error of gear was also investigated.
