The measurement of transmission error of power transmission gears is a useful tool by developing quieter gear units. Precise measurement using the conventional system with rotary encoders is, however, considerably difficult, because of elastic deformation of the measuring apparatus and connecting members between gears and encoders. In order to solve this problem a new measuring system using laser optical units, which measure the peripheral speed flutters of the rotation of the pinion and gear or their chucking bodies, has been developed. Transmission errors are calculated by integrating the difference between the speed flutter of the pinion and that of the gear. During the basic performance test of this measuring setup, in which both optical units were installed on the peripheral surface of a single rotor, an excellent noise level of 0. 002% speed flutter was confirmed. In the application test for hypoid gears, the measured values of transmission error in the tooth mesh and its higher harmonic frequency components correspond sufficiently to the values obtained using the traditional vibration tester and to those using the single flank tester of rotary encoder type.
