ISO 4183 pdf download.Belt drives – Classical and narrow V-belts – Grooved pulleys (system based on datum width)
1 Scope
This International Standard specifies the principal di- mensions of grooved pulleys for classical V-belts (sections Y, Z, A, B, C, D and E) and narrow V-belts (sections SPZ, SPA, SPB and SPC) specified in the terminology system based on datum width. It is important that narrow belts are not used with pulleys uniquely designed for classical belts, and, on the other hand, that multiple belt drives are not used with joined V-belts

3 Preliminary notes
3.1 The datum width is regarded as the basic di- mension of standardization for the groove and for the corresponding classical and narrow V-belts considered as a whole. 3.2 Knowledge of the datum line position and of the datum width is essential for defining the groove pro- file, the datum diameter of the pulley and the location of the belt in the pulley groove
4 Datum widths of profiles
The datum widths, Wd, of the profiles are specified in table 1.
