헬리컬 기어의 전달오차의 측정

The object of this work is to develop the measurement method of the transmission error of the helical gears. For this purpose, experimental set up is designed by 3D CAD software. It consists of the motor, inverter, powdered brake equipment, torque sensor and helical gearbox. In this study, tangential linear accelerometers were used as the methods for the transmission error measurement. the acceleration signals are transmitted to the signal conditioners through the slip rings and the transmission errors are obtained by a specially designed circuit board. The transmission errors are analyzed in the time domain and the frequency domain. As a result, The periodicity of the transmission error is con finned in the mesh frequency and its harmonics. Transmissin error increases as the rotational speed and torque increase.
