There can be no doubt that shafts – in all of their specialised types and constructions – are among the most fundamental components in mechanical engineering. It is their ability to conduct torque and support rotating parts that makes them so integral to just about any type of machine. In terms of its visual appearance, a shaft resembles an elongated rod or bar and is produced in a wide range of sizes. The material from which it is made is first and foremost selected to suit the intended application and the demands that it has to fulfil in use. Basic requirements such as material strength, hardenability and ductility are satisfied by various kinds of structural steel. Moreover, hardened & tempered or case hardening steels are mostly used in applications in which the shaft has to be able to withstand high load levels and fulfil additional requirements.

This consists of a concave shaft girding the driving axle and having sufficient concurrence there from to permit the necessary relative movement between the spring– borne quill and the axle. The quill carries the gearwheel (or a gearwheel at each end) engaging with a pinion on the motor shaft. A binary-or double– architecture motor is constantly employed, and to secure inflexibility the pinions may be spring gentled.
An accident passed with a unrestricted concave shaft of a screw conveyor with confines length 7 m, periphery 250 mm, and a wall consistence 6 mm, which was used for transporting raw accoutrements and recycled particulars in the granulating factory in an ammonium nitrate installation. The shaft of this screw conveyor had a weak spot with a hole at one position, caused by combing.
