Customized Alloy Steel 20CrMnTi ANSI B92.1 Spline Grinding Involute
Spline Shaft
Features of The Spline Shaft
Involute splines are the predominant form of splines because they
are stronger than straight sided splines and are easier to cut and
the fit.
Involute splines have teeth similar to gear teeth except spline
teeth are much shorter, and they do not roll.
The external splines can be formed either by hobbing are by a
spline shaper.
Internal splines can be formed by broaching or a spline shaper.
The various simplest method of initially selecting an involute
spline based on a shaft diameter is to arrive at an initial pitch
circle diameter in module.
Involute splines are used for fixed end for sliding connections of
shafts with hubs.
While splines are used in the transmission of power similar to
gears, this feature of splines is not tied to the involute profile
that splines also share with gears.
The involute profile is due to the manufacturing techniques for the
splines
