LV12759A - Swivel socket for joints - Google Patents

Abstract

An invention relates to hydraulic devices, in particular to swivel joints intended for coupling of high-pressure hydraulic hoses in hydraulic devices allowing rotation of one hose with respect to other and preventing twisting of them. The goal of an invention is to prolong service life and improve serviceability of swivel joint. According to the invention the swivel joint consists of central shaft (1), housing (2) and cover (3) with centre hole in which the central shaft is built-in. Internal end of cover (3) is guided in the direction of said cavity. At the end of cover (3) is positioned a radial thrust bearing (5) resting by its lower end on the special support consisting of disc (6) which by means of radial recess bears against two half rings (7) mounted in circular groove of central haft (1). The cover (3) which is provided with centre hole with built-in central shaft (1) is fixed to the housing (2) by screws. A plain bearing (4) is pressed into the cover (3) in order to react a radial load, said plain bearing (4) being produced from high-strength bronze and provided with special recesses for retention of grease. Providing of swivel joint with plain bearing (4) taking up radial load ensures favourable conditions during use and excludes possibility of emergence of scoring and seizure of mechanism.
