Spiral Bevel Gears
Ok..so is no secret, I have a thing for anything that spins and is round..especially if it has gears =)
What are spiral bevel gears?
A 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 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth.
This animation shows spur gears morphing into bevel gears, then into spiral bevel gears, then into helical gears, and finally back into spur gears again. Oh well, I could stare at this forever ;)
