What is the function of spider gear in a differential?
The spider gears design allows for different rotational speeds between tires. This allows for a much easier time when turning the vehicle in front wheel drive, rear wheel drive, and four wheel drive. Whenever a vehicle negotiates a turn, the outside wheel must travel farther (turn faster) than the inside wheel.
How does rear differential work?
In rear-wheel drive cars, the differential converts rotational motion of the transmission shaft which lies parallel to the car’s motion to rotational motion of the half-shafts (on the ends of which are the wheels), which lie perpendicular to the car’s motion.
Where do the spider gears in a differential go?
The spider gears transmit the force from the differential cage through the pinion shaft (goes across the case with the spider gears at each end) to the side gears, but they don’t rotate on the center pinion shaft.
How does a differential gear work in a car?
In principle, this spider gear is nothing else than a planet gear as it is known from planetary gears. And indeed, the differential gear can be seen as a special form of a planetary gearbox (more on this later). The drive of the spider gear is of course not done by hand but by the engine.
Why do you need to change spider gears?
Spider gears are responsible for the rear wheels of a vehicle to turn at different speeds, which allows for making turns smooth instead of in a jerking motion. The gears are part of the differential which is attached to the drive shaft of the vehicle. There are many signs of a spider gear beginning to age and requiring replacement.
When do side gears and ring gear turn together?
Example: A regular, open, rear differential. When both wheels are going straight on the ground and neither slips, the wheels, side gears, differential case and ring gear all turn together.
What are spider gears?
Spider gears are small gears mounted on a shaft which is pinned to the differential case. They are usually found in a set of two to four gears, meshing with the bevel gears and driving them.
What is a spider differential?
The differential Spider is a premium rock guard that protects your PCP Aluminum Cover – A superior design – all of our Spidersare built with a full 3/8 inch thick CNC Plasma cut steel flange.
What is a spider gear?
by Jennifer Rose. Spider gears are a part of your car’s gear set allowing its rear wheels to turn at different speeds when necessary without affecting the movement of the car as a whole.
What is differential gear?
differential gear. n. An arrangement of gears in an epicyclic train permitting the rotation of two shafts at different speeds, used on the rear axle of automotive vehicles to allow different rates of wheel rotation on curves.
