Differential Gears
Differential gears connect two shafts with a covering, forcing the total of the rotational angles of the shafts to be the same as the rotational angles of the covering. Arrangement of the whole system is done in such a way that one axle turns faster than the other. These differential gears are used to convert the lengthwise flow of the power from the engine through the clutches, transmissions, and propeller shafts into a right-angle direction. This change permits the engine power to turn the wheels. When the differential gear is meshed with the other gear then the highly efficient torque is applied from the differential side gears to the axle shaft. When torque level decreases then the gear separating forces also decreases permitting the axle shaft to rotate independently. Differential gears can elegantly add or subtract the movement of two inputs.
There are mainly two types of the Differential Gears- Spiral Differential gears and Hypoid Gears. In the spiral type, the pinion gear contacts the ring gear at its centerline. While in the Hypoid differential gears, the pinion contacts the ring gear below the centerline. The size of pinion gear in hypoid differential is much smaller and the contact ratio is high, comparatively hypoid differential is much stronger than the spiral differential. Differential gears are widely used in the automobiles.
