Main function of a propeller shaft is to connect a propeller to an engine. It is also the British English term for the drive shaft, which connects an automobile gearbox to a rear differential. It is commonly referred to as a "prop-shaft".
The propeller shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints. Where the engine and axles are separated from each other, as on four-wheel-drive and rear-wheel-drive vehicles, it is the propeller shaft that serves to transmit the drive force generated by the engine to the axles.
For its usage, the optimal shaft is a short, bar-like product. The longer the bar, the more liable it is to sag, and sagging is further promoted when rotation is applied. Sagging causes vibration and results in an increase in noise, to such an extent that the shaft is likely to break when the critical speed is exceeded.
Our specially designed propeller shaft is naturally made in such a way, which does not break when used within the service limits expected of use. In addition, it is designed to suppress vibrations arising from a wide range of causes.
The propeller shaft should always be connected with a flexible coupling like you can find in many rear wheel driven vehicle to eliminate all the vibrations.
