ISO FDIS 17396
Synchronous belt drives - Metric pitch - Tooth profiles T and AT endless and open ended belts and pulleys
Organization:
ISO - International Organization for Standardization
Year: 2013
Abstract: This International Standard specifies the principal characteristics of synchronous endless and open belts and pulleys of the profile systems T and AT for use in synchronous belt drives1) for mechanical power transmission and where positive indexing or synchronization can be required.
The principal belt and pulley characteristics include
a) nominal belt tooth dimensions,
b) belt tooth pitch spacing,
c) belt length and width dimensions,
d) belt length measurement specifications,
e) pulley groove dimensions and tolerances,
f) pulley diameter and width dimensions and tolerance, and
g) pulley quality specification.
The belts of the profile systems T and AT are made of polyurethane with high-tension fine steel cord tension members in most cases. As far as certain forces are given in this International Standard, these values are only valid for this kinds of belt. For polyurethane belts with different tensile cords, i.e. aramid or rubber belts reinforced with glass fibre, the values can be different. It is intended that the user and the manufacturer agree about suitable values. Open belts made of thermoplastic polyurethane can be spliced to work as endless belts in conveyor applications. In this case, the tolerances are not valid for the splicing are of the endless spliced belt.
1) Synchronous belt drives have been known by various titles in the past: for example, timing belt drives, positive belt drives, gear belt drives.
