Abstract
Splines are a series of keys machined on outside of a shaft, with corresponding grooves machined on inside of hub of a power transmitting element. The same as keys, splines are used to provide a joint connection between the hub and the shaft for torque and power transmission. However, they are typically used in applications in which a high torque needs to be transmitted. Crushing on the working surface is the potential failure mode for a spline. Therefore, the design is usually based on the bearing strength of spline. In this chapter, we propose a graphical method for designing splines.
