How to Design a Drive Shaft - Drive Shaft Design for a Constant Load

Shaft is a basic mechanical component. The concept of drive shaft design formula is explained in this article with an example shaft design problem.You can see a shaft in almost every machine, which has rotating parts. Typically a shaft has circular cross section. However, shaft with other cross sections find special application. We will discuss the design concept of a drive shaft subjected to fixed load. A drive shaft is supported by bearings at both the ends (and at regular interval in centre for longer shafts). Belt driven pulleys are placed over the shaft and between the bearings.
