A single flank gear-testing machine with two rotary encoders is developed and high precision measurement of transmission errors of gears under load is achieved. The developed measurement system has enough accuracy to investigate transmission errors of helical gears. Besides, two methods of wave removal are proposed and the influence of the accuracy of encoders on the transmission errors is investigated. It is found that the moving average method is effective to remove waviness including pitch errors. Measurement accuracy depends on the number of slits, that is to say the slit pitches, of the encoders by estimating the maximum quantization error. Moreover, absolute transmission errors of spur and helical gears are measured and amplitude changes of transmission errors on the applied load are discussed.
