What is universal joint and coupling differences?

The difference between universal joint and coupling:

1.Universal joint

Universal joint, is the realization of variable Angle power transmission parts, for the need to change the direction of the transmission axis position, it is the car drive system universal transmission device "joint" parts. SWC adopts integral fork head, which makes delivery more .The combination of universal joint and drive shaft is called universal joint transmission device. In the front engine rear wheel drive vehicle, the universal joint transmission device is installed between the transmission output shaft and the drive axle main reducer input shaft; In front-engine, front-wheel drive vehicles, the drive shaft is omitted, and the universal joint is installed between the front axle, which is responsible for both driving and steering, and the wheels.

2. Coupling

A machine part used to connect two shafts (drive and driven) in a different mechanism so that they rotate together to transmit torque. Its transmission efficiency is 98-99.8%, used for high-power .In high speed and heavy load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of shafting. The coupling consists of two halves connected with the driving shaft and the driven shaft respectively. General power machines are usually connected with working machines by means of couplings.
