1) Applications of spiral bevel gear Shaft

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.

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.

Typical gear ratios are 1:1 to 5:1.

The axes of a spiral bevel system are on the same plane.
