Design Parameters for Spline Connections
www.geartechnology.comIf the splines are being designed, then one of the preferred pres-sure angles from the standards should be used. ANSI and DIN offer the choice between 30°, 37.5° and 45°. In the JIS standard also a pressure angle of 20° is proposed. If the spline is designed for an aftermarket product (for example the sprocket shown Fig. 7), then a simple ...
