21.120.30 - Keys and keyways, splines

This document specifies the rules and graphical symbols for the representations of splines and
serrations in technical product documentation.
Two methods of representation are specified:
a) complete representation;
b) simplified representation.
The rules and graphical symbols specified in this document are applicable to detail drawings of parts
(shafts and hubs) and to assembly drawings of joints.
NOTE For uniformity, all the figures in this document have been drawn in the first-angle ort...view more

This part of ISO 4156 provides the data and indications necessary for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing errors and their effects on the fit between connecting coaxial spline elements are defined in the equations and given in the tables. Unless otherwise specified, linear dimensions are expressed in millimetres and angular dimensions in degrees.

This part of ISO 4156 provides data and guidance for the inspection of straight (non-helical) side fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing errors and their effects on the fit between connecting coaxial spline elements are defined and tabulated.

ISO 4156-3:2005 provides data and guidance for the inspection of straight (non-helical) side fitting cylindrical involute splines.

ISO 4156-1:2005 provides the data and indications necessary for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines.

ISO 4156-2:2005 specifies geometry and inspection dimensions for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. The specified diameters for external splines in the geometry tables and the values in the inspection dimension tables are only valid for fundamental deviation h. For fundamental deviations other than h, diameters and tooth thicknesses are calculated for external splines according to the formulae in ISO 4156-1:2005 and inspection dimensio...view more

Is intended for the general application to cylindrical shafts and gives the relationship which should be observed between the diameter of shaft and the section of key. Steel with a tensile strength of 590 N/mm is defined as the material to be used.

Is intended for the general application to cylindrical shafts and shafts ends, and gives the relationship which should be observed between the diameter of shaft and the section of key. Steel with a tensile strength of 590 N/mm is defined as the material to be used.

Contains table indicating tolerances on holes and shafts as well as on symmetry, gives directions for gauging such as gauging conditions and gauging control, and specifies control methods and corresponding gauges.
