14、 Nov 26 06:31:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical com
15、mittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
16、 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Internatio
17、nal Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be t

Straight cylin
21、drical involute splines manufactured in accordance with ISO 4156 are used for clearance, sliding and interference connections of shafts and hubs. They contain all the necessary characteristics for the assembly, transmission of torque, and economic production. The nominal pressure angles are 30, 37,5
22、 and 45. For electronic data processing purposes, the form of expression 37,5 has been adopted instead of 3730. ISO 4156 establishes a specification based on the following modules: for pressure angles of 30 and 37,5 the module increments are 0,5; 0,75; 1; 1,25; 1,5; 1,75; 2; 2,5; 3; 4; 5; 6; 8; 10 f
23、or pressure angle of 45 the module increments are 0,25; 0,5; 0,75; 1; 1,25; 1,5; 1,75; 2; 2,5 BS ISO 4156-3:2005 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 06:31:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI blank Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 06:31:59 GMT+00:00
