END SEAL

摘要

FIELD: machine building.SUBSTANCE: end seal includes a rotating ring installed tightly on the shaft and contacting a non-rotating ring so that a friction pair is formed. The non-rotating ring is installed in the housing and spring-loaded in the direction of the rotating ring relative to an annular piston installed in an annular slot of the housing interconnected with system of working medium supply under pressure. The supply system includes pressure controls related to a temperature sensor installed in the friction pair and an oil pump.EFFECT: improving reliability of the seal owing to excluding formation of increased temperature in friction pair.4 cl, 1 dwg
