PLANETARY REDUCER FOR TURBOMACHINE IN PARTICULAR Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: planetary reducer, in particular for a turbomachine, contains coaxial inner and outer planetary gears, the outer planetary gear is fixed, at least one satellite that is mounted rotatably on the carrier and engages simultaneously with the inner and outer planetary gears. The carrier rotates around the axis of the inner and outer planetary gears. The satellite comprises a cylindrical inner surface mounted rotatably around the cylindrical surface of the carrier. The gear unit also comprises oil supply means at a level of contact area between said cylindrical surfaces. The oil supply means comprise a chamber made in the carrier and designed to form certain volume of buffer oil and comprises a lower area distanced from the carrier rotation axis, the upper area located close to the carrier rotation axis, at least one main channel leading to a level of said contacting area and the upper area level, and at least one auxiliary channel leading to the level of said contact area and to the lower area level.

EFFECT: improved lubrication quality of the planetary reducer.
