Introduction to Spline Shaft

A spline shaft is a mechanical component that features ridges or teeth, known as splines, machined onto its outer surface. These splines fit into corresponding grooves in a mating part, such as a gear, coupling, or hub. The main function of a spline shaft is to transmit torque between two rotating components while allowing for some degree of axial movement. They are widely used in various industries, including automotive, aerospace, machinery, and power transmission, due to their high torque - transmitting capacity, accurate positioning, and reliable performance.
