DIN Standards Committee Mechanical Engineering

Overview

This document specifies geometry and inspection dimensions for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing deviations and their effects on the fit between connecting coaxial spline elements are defined in the formulae and given in the tables. Unless otherwise specified, linear dimensions are expressed in millimetres and angular dimensions in degrees. This document contains the German translation of the International Standard ISO 4156-1:2021, which has been prepared by Technical Committee ISO/TC 14 "Shafts of machinery and accessories", the secretariat of which is held by DIN (Germany). The responsible national standardization committee is Working Committee NA 060-34-31 AA "Passverzahnungen" ("Splines") at DIN Standards Committee Mechanical Engineering (NAM).
