Analytic and FEM Study of Load Distribution on the Length of Spline Joints Under Pure Torque

Because spline joints transmit torque from shafts to rotors by multiple contact surfaces, the joint’s mechanical system is undetermined, thus, the actual load distribution is greatly influenced by the joint’s elements elastic properties. In previous works, an analytical method using differential equations of 2nd order to determine load distribution on joints’ length was proposed. In this paper, a comparison between analytical and experimental study results for the load distribution on the length of joints under pure torque is presented.
