適用范圍：This part of ISO 4156 specifies geometry and inspection dimensions for the design and manufacture ofstraight (non-helical) side-fitting cylindrical involute splines.Limiting dimensions, tolerances, manufacturing errors and their effects on the fit between connecting coaxialspline elements are defined and tabulated. Linear dimensions are expressed in millimetres and angulardimensions in degrees.The specified diameters for external splines in the geometry tables and the values in the inspection dimensiontables are only valid for fundamental deviation “h”.For fundamental deviations other than “h”, diameters and tooth thicknesses are calculated for external splinesaccording to the formulae in ISO 4156-1 and inspection dimensions according to the formulae in ISO 4156-3.
