1) Description of spiral bevel gear
Spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential.
Where the direction of drive from the drive shaft must be turned 90° to drive the wheels. The helical design
produces less vibration and noise than conventional straigh-cut or spur-cut gear with straight teeth.

replaced together.
