1) Description of Spiral Bevel Gears

Spiral Bevel gears are conical gears with helical teeth.

The most important application of this transmissionis in applications, similar to the differential of a car, where the drive angle is shifted by 90 degrees.

The spiraldesign produces less vibration and noise than conventional straight model or straight cut gear with straight teeth.

2) Features of Spiral Bevel Gear 

A spiral bevel gear has teeth cut in helical form with the pitch surface being conical.

This results in a reduction in noise and vibration through the gradual engagement of spiral teeth with the

contact starting at one end of a gear tooth and progressively spreading across the whole tooth flank.
