1) The Main Factors of Involute Splines

a) Thickness and the height of the teeth.

    The height and thickness of the teeth on a spline are calculated based on the root strength of the spline and

    the expected torque requirements of the application.

b) Pressure angle of the application. Splines are generally available in pressure angle  of 30, 37.5, and 45 degrees.

    Size and pressure angle are determined based on the desired tooth engagement and spline fit.

c) Coupling configuration. Splines can be constructed in either side-fit or major diameter couplings.

    Major diameter couplings have a more precise fit requirement than side-fit splines and are less capable of self-alignment.

    Additionally, they are less forgiving of size deviations for internal and external spline components,

    while side-fit splines can work within greater size tolerances.

    Ideally, the teeth and grooves of mated parts should mesh precisely with little or no space between them.
