Abstract
Based on the meshing theory of spiral bevel gears, the Transmission error (TE)curves of two different pairs of spiral bevel gears (one pair is modified spiral bevel gears, another one is general spiral bevel gears) are achieved. According to the characteristic of theoretical TE curve, the spiral bevel gear transmission error measurement system is designed, and the comparative experiment for the two pairs of gears were carried out on the system under different loads. The real TE of the two pair of gears has acquired. The experimental results show that modified spiral bevel gear pair is better than the general one in the dynamic behavior, which was verified the new method that modifies tooth face with modified tools is useful and effective to reduce gear vibration and noise.
