Description / Abstract:

This standard applies to involute splines and spline joints based on reference diameters for connecting hubs and shafts either with a removable connection, a sliding fit or a permanent fit. It lays down the following general characteristics for splines as in this standard:

a) They have a standard pressure angle of 30┬░.

b) The basic rack profile is the same for all pitches, therefore applying a uniform design rule to all profiles.

c) They have a side fit profile (a diameter fit is permitted in some cases).

d) Addendum modification is used in order to achieve specific reference diameters.

e) The fit system includes tolerances for effective form deviations so that the effect of such deviations on backlash is taken into account. The specified range of fundamental deviations and tolerance classes takes due consideration of all requirements.
