shaft

A shaft is a rotating member usually of circular cross-section (solid or hollow), which transmits power and rotational motion.
Machine elements such as gears, pulleys (sheaves), flywheels, clutches, and sprockets are mounted on the shaft and are used to transmit power from the driving device (motor or engine) through a machine.
Press fit, keys, dowel, pins and splines are used to attach these machine elements on the shaft.
The shaft rotates on rolling contact bearings or bush bearings.
Various types of retaining rings, thrust bearings, grooves and steps in the shaft are used to take up axial loads and locate the rotating elements.
Couplings are used to transmit power from drive shaft (e.g., motor) to the driven shaft (e.g. gearbox, wheels).
