| Summary: | <strong><span style="font-family: Arial; font-size: small;"><strong><span style="font-family: Arial; font-size: small;"><p>Resumen</p></span></strong></span></strong><span style="font-family: Arial; font-size: x-small;"><span style="font-family: Arial; font-size: x-small;"><p>En el contexto de las actuales normas internacionales, no se dispone de información suficiente para</p><p>enfrentar el cálculo analítico de la potencia transmisible por una correa dentada. Esta situación</p><p>restringe el desarrollo de un cálculo computacional o la estimación de la potencia nominal de las</p><p>correas dentadas para casos no contemplados en los datos declarados por los fabricantes y</p><p>derivados de ensayos experimentales. Por tal motivo, y con el interés de difundir el cálculo analítico</p><p>de la potencia nominal en transmisiones por correas dentadas, se proporcionan en este trabajo</p><p>fórmulas de potencias nominales y también términos y factores de corrección apropiados para el</p><p>cálculo y estudio de transmisiones por correas dentadas con dos poleas. Además, se presentan</p><p>valores óptimos de velocidad de correa para valores obtener valores máximos de potencia</p><p>transmisible por una correa dentada en función del paso. Estos resultados han sido base de una</p><p>propuesta informativa incorporada a la norma cubana NC-ISO 5295:2010 referida al cálculo de las</p><p>potencias nominales de correas dentadas con flancos de perfil recto.</p></span></span><strong><span style="font-family: Arial; font-size: small;"><strong><span style="font-family: Arial; font-size: small;"><strong><span style="font-family: Arial; font-size: small;"><p>Palabras claves:</p></span></strong></span></strong></span><p> </p></strong><span style="font-family: Arial; font-size: x-small;"><p><span style="font-family: Arial; font-size: x-small;">Correa dentada, potencia nominal, Norma ISO 5295, velocidad óptima.</span></p><p><span style="font-family: Arial; font-size: x-small;">_____________________________________________________________________________</span></p><strong><span style="font-family: Arial; font-size: small;"><strong><span style="font-family: Arial; font-size: small;"><p>Abstract</p></span></strong></span></strong><span style="font-family: Arial; font-size: x-small;"><span style="font-family: Arial; font-size: x-small;"><p>In the current context of the International Standards, there is not enough information to face the</p><p>analytical calculation of the power rating of synchronous belt drives. It’s practical habitual to use</p><p>power rating diagrams or tables offered by belt manufacturers with limitation to implement</p><p>computational procedures, and for calculating ratings which are out of the range of speed or number</p><p>of teeth of pulleys conditions shown in the power rating diagrams or tables. For such a reason, this</p><p>article presents some useful results and detailed formulae based in ISO Standard 5295 for power</p><p>ratings, together with appropriate correction terms and analytical factors used in the calculation of</p><p>power rating of synchronous belt drives. Formulae and analytical factors for the study and design of</p><p>synchronous belt transmissions are presented. Moreover, some results of optimal values of belt</p><p>velocity for maximum power capacity are offered. Results presented in this paper were the bases for</p><p>an informative proposal annexed to the Cuban Standard NC-ISO 5295:2010 referred to the analytical</p><p>calculation of power ratings in synchronous belt drives.</p></span></span><strong><span style="font-family: Arial; font-size: x-small;"><strong><span style="font-family: Arial; font-size: x-small;"><strong><span style="font-family: Arial; font-size: x-small;"><p>Key words:</p></span></strong></span></strong></span><p> </p></strong><span style="font-family: Arial; font-size: x-small;"><p><span style="font-family: Arial; font-size: x-small;">Synchronous belt drives, power rating, ISO NC Standard 5295, rational belt velocity.</span></p></span></span> |
