What is the base diameter of a spline?
What is the base diameter of a spline? Base Circle is the circle from which involute spline tooth profiles are constructed. Base Diameter (Db) is the diameter of the base circle. circular pitch. The basic space width for 37.5- and 45-degree pressure angle splines, how- ever, is greater than half the circular pitch. How do you calculate spline modules? a spline for a 50mm OD spline with say a module of 2mm would have a PCD (D) of 50 - 2 = 48mm. The number of teeth = D/m and as an whole number of teeth is required a value...
