GONZALEZ REY, Gonzalo  y  GARCIA DOMINGUEZ, Maria Eugenia. An analytical calculation of the power rating of synchronous belt drives. Ingeniería Mecánica [online]. 2010, vol.13, n.2, pp. 49-61. ISSN 1815-5944.

In the current context of the International Standards, there is not enough information to face the analytical calculation of the power rating of synchronous belt drives. It's practical habitual to use power rating diagrams or tables offered by belt manufacturers with limitation to implement computational procedures, and for calculating ratings which are out of the range of speed or number of teeth of pulleys conditions shown in the power rating diagrams or tables. For such a reason, this article presents some useful results and detailed formulae based in ISO Standard 5295 for power ratings, together with appropriate correction terms and analytical factors used in the calculation of power rating of synchronous belt drives. Formulae and analytical factors for the study and design of synchronous belt transmissions are presented. Moreover, some results of optimal values of belt velocity for maximum power capacity are offered. Results presented in this paper were the bases for an informative proposal annexed to the Cuban Standard NC-ISO 5295:2010 referred to the analytical calculation of power ratings in synchronous belt drives.

Palabras clave : synchronous belt drives; power rating; ISO NC standard 5295; rational belt velocity.
