Liquid-lubricated expansible v-pulley system

Abstract

Abstract A RESILIENTLY-EXPANSIBLE V-PULLEY COMPRISING A HUB, A CONED DISC AXIALLY MOVABLE ON THE HUB, THE CONED DISC HAVING AN AXIAL BORE FOR TELESCOPICALLY RECEIVING THE HUB, THE BORE BEING FORMED WITH A PERIPHERALLY AND AXIALLY EXTENDING CUTOUT INTERMEDIATE ITS ENDS AND PROVIDING A RESERVOIR. MEANS PROVIDING A SEAL BETWEEN THE DISC AND THE HUB AT EACH END OF THE RESERVOIR ARE PROVIDED AND POROUS MEANS DISPOSED IN AND SUBSTANTIALLY FILLING THE RESERVOIR IS PROVIDED, THE POROUS MEANS BEING IMPREGNATED BY LIQUID LUBRICANT. THE LUBRICANT, WHICH IS FED TO THE OUTER SURFACE OF THE HUB BY THE POROUS MEANS, SERVES TO PREVENT FRETTING CORROSION. MEANS FOR PREVENTING RELATIVE ROTATION BETWEEN THE DISC AND THE HUB IS PROVIDED, WHICH MEANS DOES NOT PENETRATE THE RESERVOIR. IN ONE EMBODIMENT OF THE INVENTION, THIS MEANS INCLUDES A KEY CARRIED BY THE SLEEVE PORTION OF THE DISC SO THAT, IN ITS AXIALLY INNERMOST POSITION, THE KEY IS AXIALLY OUTWARDLY FROM THE RESERVOIR, IN ANOTHER EMBODIMENT, THE CONVENTIONAL COILED COMPRESSION SPRING WHICH URGES THE DISC AXIALLY INWARDLY PROVIDES A DRIVING CONNECTION BETWEEN THE DISC AND THE HUB, ONE END OF THE SPRING BEING CONNECTED TO THE DISC AND THE OPPOSITE END OF THE SPRING BEING CONNECTED TO THE HUB, AND IN A FURHTER EMBODIMENT, THE DRIVING CONNECTION BETWEEN THE DISC AND THE HUB IS PROVIDED THROUGH THE CARTRIDGE WHICH CONTAINS THE COMPRESSION SPRING.
