Abstract

LA POLEA SE COMPONE DE UNA ESTRUCTURA DE GUIADO (3) DE SEGMENTOS (4) DESPLAZABLES SEGUN EL REGLAJE DE BIELAS (7) PROLONGADAS SIMETRICAMENTE RESPECTO A UN PIVOTE (9) Y LLEVAN UN CONTRAPESO OPUESTO. LOS SEGMENTOS (4) SON ARCOS DE CIRCUNFERENCIA PARA ASEGURAR UNA BUENA ADHERENCIA DE LA CORREA. LOS CONTRAPESOS SON SEGMENTOS (42), LO QUE PERMITE QUE OBTENER UNA POLEA DOBLE CERRADA CON DOS POLEAS COAXIALES CUYOS DIAMETROS VARIAN EN SENTIDOS OPUESTOS. LA FUERZA CENTRIFUGA SOBRE LOS SEGMENTOS (4) PUEDE SER EQUILIBRADA. APLICACION A VARIADORES DE VELOCIDAD CONTINUOS.
