Reduction of Spiral Bevel Gear Noise in 4-Wheel Drive Vehicle Transfer System 922109

Mitsubishi Motors Corporation uses spiral bevel gears in the transfer system for 4-wheel drive passenger cars modified from the front wheel drive configuration. This transfer gear ratio is near 1:1, and gears have uniform depth teeth cutting by the continuous generating method of OERLIKON cutting machine. In this method, the cutter and the work rotations are timed together to accomplish continuous indexing and cutting in order to enable high productivity.

In general, it is difficult to reduce the meshing noise of spiral bevel gears and control its quality. The authors established the tooth surface coordinates, to reduce the meshing noise, by studying the influence of tooth surface coordinates on the meshing transmission error (MTE).
