The DIN 5480 and DIN 5482 series of standards is limited to splines with a pressure angle of 30°, since pressure angles of 37.5° and 45° are covered by ISO 4156ĪNSI B92.1 covers pressure angles of 30, 37. (6) Involute splines are typically made with pressure angles of 30°, 37.5°, or 45°. Illustration bellow of how the shape of gear teeth change as the pressure angle, changes. The pressure angle is the angle between the tangent to the pitch circles and the line drawn normal (perpendicular) to the surface of the gear tooth Pitch Diameter, D The diameter of the pitch circle. Its diameter is determined as the ratio of the number of teeth to the diametral pitch. Pitch Circle is the reference circle from which all circular spline tooth dimensions are constructed. My experience with splines goes back to the early 70's when I wrote a program to convert a smooth curve to a series of arcs and lines. Module m = D/N = mm of pitch diameter per toothĪ gear with 10 teeth and 1.000 inch pitch diameter Bezier splines is the foundation for B-Splines and NURBS curves and surfaces. The metric system uses MODULE to characterize teeth size. Pd = N/D = number of teeth to inches of pitch diameter The imperial system uses DIAMETRAL PITCH to characterize teeth size. This applies to DIN 5480, DIN 5482, ISO 4156, ANSI B92.2M, ANSI B92.1, and similar splines External in the shaft and internal in the hub. Involute Spline is a spline having teeth with involute profiles. In splines or spur gears, a fraction of the profiles is an involute of a circle.

The involutes used in gearing or in splines connections are involutes of circles.

Step 1: Generation of an involute profileĪ curve that is obtained by attaching a string that is imaginary and then winding and unwinding it tautly on the curve given is called involute in differential geometry.This is a short description of how involute profiles are used in splines like DIN 5480, DIN 5482, ISO 4256, and ANSI 92.1
