BEARING UNIT Russian patent published in 1998 - IPC

FIELD: instrument engineering; bearings furnished with lubrication system. SUBSTANCE: bearing unit mounted in housing has bearing whose inner race is fitted on shaft. Oil filled space is formed by inner bushing and outer bushing interference-fitted on inner bushing to form oil feed channel. Oil feed channel outlet is formed by end face surface of outer bushing and inner race. With shaft rotating, oil acted upon by centrifugal forces, is delivered through oil feed channel onto outer surface of inner race. Then oil, according to thermocapillary flow law, passes to more heated place, i. e. to race, and then to surfaces of balls and inner race. EFFECT: enlarged operating capabilities. 1 dwg
