Spiral bevel gears are used in situations where the axis of rotation of a shaft must change direction.
An example of this is a car differential where the rotating prop shaft is turned through 90° to drive the wheels.
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.
Typical gear ratios are 1:1 to 5:1.
The axes of a spiral bevel system are on the same plane.
