Over current and earth fault protection
It is customary to have two elements of over current and one element of earth fault protection system in the most elementary form of protection of three phase feeders. Different…
Differential Introduction
A differential is a device, usually, but not necessarily, employing gears, capable of transmitting torque and rotation through three shafts, almost always used in one of two ways: in one way, it receives…
Fluid Coupling
It is a device for transmitting rotation between shafts by means of the acceleration and deceleration of a hydraulic fluid (such as oil). Also known as hydraulic coupling. Structurally, a…
Different Types of Clutch
Friction Clutch Friction clutches are the most commonly used clutch mechanisms. They are used to transmit torque by using the surface friction between two faces of the clutch. Dog Clutch…
Requirements of a Good Clutch
1. Torque Transmission 2. Gradual Engagement 3. Good Heat Dissipation 4. Compact Size 5. Sufficient Clutch Pedal Free Play 6. Ease of Operation
Clutch Introduction
A Clutch is a machine member used to connect the driving shaft to a driven shaft, so that the driven shaft may be started or stopped at will, without stopping the driving shaft.…
Anti-Braking System
Anti-Braking System is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking, preventing the wheels from locking up (that is,…
Air Brake System
Air Brake System is the brake system used in automobiles such as buses, trailers, trucks, and semi-trailers. George Westinghouse created air brakes for utilizing it in trains for railway service. A…
Hydraulic Brake
Hydraulic Brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit, which is usually near the operator of the vehicle, to the…
Frictional, Pumping, Electromagnetic brakes
1. Frictional brakes are most common and can be divided broadly into "shoe" or "pad" brakes, using an explicit wear surface, and hydrodynamic brakes, such as parachutes, which use friction in…
