The work of preparing International Standards is normall
15、y carried out through ISO technical committees. 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
16、work. ISO collaborates closely with the 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 In
17、ternational Standards. Draft International 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
18、 the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4156-2 was prepared by Technical Committee ISO/TC 14, Shafts for machinery and accessories. This first edition of ISO 4156-2, together with ISO 415
19、6-1 and ISO 4156-3, cancels and replaces ISO 4156:1981 and ISO 4156:1981/Amd 1:1992, of which it constitutes a technical revision. The values and tables are the same as in ISO 4156:1981; however, some explanations and definitions have been clarified. ISO 4156 consists of the following parts, under t
20、he general title Straight cylindrical involute splines Metric module, side fit: Part 1: Generalities Part 2: Dimensions Part 3: Inspection BS ISO 4156-2:2005vIntroduction ISO 4156 provides the data and indications necessary for the design, manufacture and inspection of straight (non-helical) side-fi
21、tting cylindrical involute splines. Straight cylindrical 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 pr
22、oduction. The nominal pressure angles are 30, 37,5 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; 0,7
23、5; 1; 1,25; 1,5; 1,75; 2; 2,5; 3; 4; 5; 6; 8; 10 for 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 4156-2:2005blank1Straight cylindrical involute splines Metric module, side fit Part 2: Dimensions 1 Scope This part of ISO 4156 specifies geometry an
24、d 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 e
25、xpressed 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 ar
