Types of Differential Gears

differential gearsTypes of Differential Gears :

There are two designs of differential gears, hypoid and spiral.

Spiral Differential:
In spiral differential the pinion gears contacts the ring gears at its centerline .

Hypoid Gear:
In the hypoid the pinion gear 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.
