ISO/TC 14 - Shafts for machinery and accessories

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 errors and their effects on the fit between connecting coaxial spline elements are defined and tabulated. Linear dimensions are expressed in millimetres and angular dimensions in degrees. 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 and inspection dimensions according to the formulae in ISO 4156-3.

This document provides data, guidance and requirements for the inspection 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 and tabulated. Linear dimensions are expressed in millimetres and angular dimensions in degrees.

This document provides the data and indications necessary 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.

ISO 4156-3:2005 provides data and guidance for the inspection 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 dimensions according to the formulae in ISO 4156-3:2005.

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

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.

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.

Specifies four series in millimeters and five series in inches of shaft heights, indicating tolerances such as limit deviations and parallelism errors.

Provides data (in 111 tables) and indications necessary for inspection as well as three methods of inspection by limit gauges.

Provides data and guidance for the design, manufacture and inspection of the involute splines. Limiting dimensions, tolerances and manufacturing errors are defined and tabulated. Linear and angular dimensions are expressed in mm and degrees, respectively.

Also specifies the material of the keys, gives the relation which should be observed between the diameter of shaft and the section of key, and is of general application for cylindrical shaft ends. It is recommended that the values given be adhered to even for special applications. For normal taper keys and corresponding keyways refer to ISO/R 773.
