1) Description of Spiral Bevel Gears
Spiral Bevel gears are conical gears with helical teeth. The most important application of this transmission
is in applications, similar to the differential of a car, where the drive angle is shifted by 90 degrees. The spiral
design 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.
