GEARS | SPIDER GEARS - What are spider gears and what do they do?

Accepted Answer

Spider gears are also known as satellite gears, they rotate around the side gears in the differential carrier. Side gears may also be referred to as axle gears or planetary gears. The spider gears are the ones with the cross-pin shaft going through them. This array of spider and side gears take the rotational energy from the driveshaft and help redirect it outwards to the axles and on to the wheels. They also play a key role in allowing the wheels to rotate at different speeds when the vehicle is turning.
