FIELD: machine building.
SUBSTANCE: reduction gear unit with shaft sealing system includes housing (1) with oil casing (2), gear wheels (10) and pinions (8) installed on shafts (7, 9) with seals (11, 12; 13, 14) of their outlet ends, which are arranged in bearings. At least one of seals is two-stage and has intermediate chamber (15, 16) between stages, with gear-type lubrication pump (17) and casing oil supply and discharge pipelines (19, 22). Intermediate chamber of seal of outlet shaft end of reduction gear is interconnected with oil casing by means of pipeline the outlet of which is connected either to receiving hole (18) of suction pipeline (19) of lubrication gear-type pump (17), or to ejector the nozzle of which is connected to oil pressure line of lubrication gear-type pump.
EFFECT: invention allows improving operating reliability of reduction gears, including reduction of fire risk by forced suction of oil leaks from chambers; improving environmental conditions and reducing oil consumption.
