AS B213-1966

Specifies dimensions of involute splined shafts and holes with a 30 degrees pressure angle. Basic formulas for calculating dimensions and tolerances are included, with guidance on obtaining the fit desired. Terms used are defined. The Standard also describes methods of gauging and inspecting splines, with methods of obtaining dimensions and tolerances for gauges. Inspection of splines using pins is covered and tables of measurements over and between pins are included.

This British Standard provides data and guidance for the design of straight involute splines of 30 pressure angle, tabulates limiting dimensions and deals with manufacturing errors and their effect on the fit between mating spline elements.The range of splines covered is:Side fit, 2.5/5 to 32/64 pitch, flat root 6 to 60 splines inclusive Major diameter fit, 3/6 to 16/32 pitch, flat root 6 to 60 splines inclusive Side fit, 2.5/5 to 48/96 pitch, fillet root 6 to 60 splines inclusive (see figure 1)
