BetaBetaBetaWorks out an ANSI B92.1 involute spline from its teeth and pitch: its pitch diameter and module, and the major and minor diameters of the shaft and the hub.
The teeth are unshifted, the pitch diameter the teeth over the pitch. Example: 24 teeth of 16/32 -> 1.5 pitch diameter, shaft 1.5625 across its tips, hub 1.4375 across its own
The teeth, the pitch and the unit
The spline's sizes in unit
The sizes of ANSI B92.1 involute splines, 30 degree flat root side fit, with no CAD kernel needed, in the unit asked for.
