GEAR PUMP WORKING PRINCIPLE

The gear pump working animation video below describes the working principle of the spur type gear pump, which is more common. In the gear pump, one of the rotors receives drive from an external source and directly transmits the drive to the other rotor. Since the rotors make direct contact they are not preferred for pumping suspended solids.

Differential gear Box

Principle of differential-If a vehicle travels in a straight line, the two rear wheels turn exactly at the same speed, and there is no relative movement between them. But when the vehicle takes a turn the outer wheel travels a longer radius than the inner wheel i.e. there is relative movement between the two rear wheels. The outer wheel turns faster and covers a …

Gears

Thinking of gears as levers shows exactly how they work. Suppose you turn the axle at point (1). The bar connecting points (1) and (2) moves faster and with less force at point (2) because it's working as a lever. If you can't see this, suppose the red bar were a spanner and you pushed at point (2) to undo a nut at point (1) in the center.
