7、This British Standard has been prepared by Technical Committee TDW4 and is the English language version of EN IS0 6413 : 1994 Technical drawings - Representation of splines and serrations, published by the European Committee for standardization (CEN). It is identical with IS0 6413 : 1988, published
8、by the Intedonal Organkation for Standardization (EO). This British Standard partially supersedes BS 308 : Part 1. It is envisaged that when the full range of European Standards on technical drawing is implemented BS 308 wiii be withdrawn. Cross-references Publication referred to IS0 14: 1982 Corres

Two methods of representation are specified as follows : For the purposes of this International Standard, the following definitions apply. 3.1 spline joint : Connecting, Co-axial, elements that trans- mit t

20、156 : 19811 The rules and graphical symbols specified in this International Standard are applicable to detail drawings Of the Parts (shafts and hubs) and to assembly drawings of joints. NOTE - For uniformity all figures in this International Standard are drawn in the first-angle orthographic project
21、ion. It should be understood that the third-angle orthographic projection could equally well have been used without prejudice to the principles established. 3.2 spline : One member of a spline joint having teeth orspaces that have involuteflank profiles. 1S04156: 19811 3.3 straight-sided Spline : On
22、e member of a spline joint having teeth or spaces that have straight-sided flank profiles. 3.4 serration : One member of a spline joint having teeth or spaces that generally have flank profiles of 60“ pressure angle. 2 Normative references 4 Designation The designation of spline joints shall consist

Figure 6 shows an example of a complete representation of a serration. 5 Complete representation of spline joints A complete representation of spline joints showing all details with their

If such a representation has to be made, the drawing rules laid down in IS0 128 shall be applied. tf necessary, a designation of the spline joint in accordance with clause 4 may be added.

In the axial

Usually, only the usable length of a splined part shall be drawn

Figure 7 Figure 8 6.2.6 Position of teeth If it is essential to indicate the position of the teeth in relation to a given axial
40、 plane, one or two teeth may be drawn with a con- tinuous thick line (see IS0 128, line type A) (see figure 9). 6.2.7 Detailed drawing of tooth profile If the designation is not sufficiently clear, a detailed drawing of the tooth profile should be added (see figure 10).
