A Spline Shaft is designed to transmit torque while allowing relative movement between two parts. It consists of a cylindrical shaft with a series of evenly spaced splines along its length. These splines fit into corresponding grooves in another part, such as a coupling or gear, creating a secure connection.Attributes:• Hardened to indicate its resistance against deformation• Withstand high-pressure and temperature conditions during the operationApplications:A Spline Shaft helps in providing a precise fit and minimizing play between components, ensuring effective power transfer and helping maintain optimal cooling performance.
