Design Parameters for Spline Connections

If 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 ...

Because of the thread geometry, a hardness test is not practical in the threads themselves and a tensile test is a better indication of overall bolt strength. The additional hardness of the threads provides
