CYCLOIDAL REDUCER, FAN MODULE OF DUAL-FLOW TURBOJET ENGINE AND DUAL-FLOW TURBOJET ENGINE Russian patent published in 2017 - IPC F02C7/36 F01D25/18 

FIELD: engines and pumps.

SUBSTANCE: cycloidal reducer contains a planetary gear, satellite gears driven by the planetary gear and rotating around the satellite axis mounted on the carrier. The satellite gears roll over a fixed crown gear and the carrier is located in the axial direction laterally to the crown gear. The toothed gearing, formed by the satellite gears and crown gear, is designed to discard lubrication oil in the axial direction after it has been used. The carrier contains a radial extension including a surface opposite the toothed gearing and configured to redirect lubrication oil from its axial direction to the radial direction for removal at its end by a centrifugal action. Radially beyond the carrier and opposite to the radial extension in the axial direction there is a fixed oil pan. Other inventions of the group belong to the fan module of a dual-flow turbojet engine which contains a fan shaft, rotated by the above reducer, as well as to a dual-flow turbojet engine, which contains such a fan module.

EFFECT: group of inventions allows to raise reliability of the cycloidal reducer by providing a possibility of diversion of the lubrication oil therefrom.
