Abstract

PROCEDIMIENTO PARA ELIMINAR EL RUIDO EN LAS BOMBAS HIDRAULICAS DE ENGRANAJES. UN REBAJE REALIZADO EN UNA DE LAS TAPAS LATEALES DE LA BOMBA COMUNICA LOS VOLUMENES VARIABLES APRISIONADOS ENTRE LOS DIENTES. EL REBAJE (22) SE TRAZA RETIRADO, CON UN PEQUEÑO MARGEN DE SEGURIDAD (M), CON RESPECTO A LAS RECTAS DE PRESION (13 Y 15). LA MARCA (22) QUEDA LIMITADA POR LAS CUERDAS DE LOS CIRCULOS (11) Y ADOPTA LA FORMA DE DOS TRIANGULOS ISOSCELES CUYOS VERTICES SE OPONEN ENTRE SI. UNA CORTA RANURA (23) UNE ENTRE SI LOS DOS TRIANGULOS ISOSCELES DE MANERA QUE SE ESTABLECE COMUNICACION ENTRE LOS VOLUMENES APRISIONADOS DE LOS DIENTES. CADA UNO DE LOS TRIANGULOS DE LA MARCA (22) SE COMUNICA A LA SALIDA POR UNA RANURA (24). NO SE ESTABLECE COMUNICACION ENTRE LA SALDIA (7) Y LA ASPIRACION (8).
