This component generator is intended for parallel spline calculations and designs. It designs spline shafts and provides a strength check. Using the calculation of spline joints the economic hub length for specified transferred torque is determined.
Circumferential force is transferred by the pressure of sides of shaft keys to hub grooves or vice versa. The necessary hub length is determined from the condition that the allowable pressure in the groove bearing area must not be exceeded.
Parallel splines are suitable for transfer of great, cyclical, and shock torsional moments. These couplings represent in practice the most common type of splines (approximately 80%). This type is used both for fixed and sliding couplings of cylindrical shafts with hubs.
Advantages of the coupling:
Disadvantages of the coupling:
The method of centering is chosen according to technological and operational requirements and demands for accuracy. Centering is possible on the inner diameter (used rarely) or on sides of teeth. Centering on diameters is used in case of a need for higher accuracy of the bearing. Couplings centered on the sides show higher loading capacity and are suitable for loading with variable moments and shocks.
