Submersible planetary reducer

Abstract

The invention relates to a submersible planetary reducer, and solves the problems of complicated structure and higher vibration due to use of independent structures for a high-speed rotor and a turbine shaft system in a traditional speed reducer, and increment of the system complexity and reduction of the system reliability due to use of a single cooling medium supply system for the speed reducer.The planetary reducer is mounted in an inner cavity formed by an input shaft support shell and an output shaft support shell, and comprises a sun gear, a planet gear, an inner gear ring, a planet carrier, an end ring, a bearing, an output shaft and an input shaft; the planet carrier is positioned at one end of the output shaft, and is integrally arranged with the output shaft; the planet gear ismounted on a planet carrier small shaft through the bearing; the end ring is arranged at the end part of the planet carrier, and is provided with a positioning hole as many as the planet carrier smallshaft; the sun gear is mounted on the input shaft, and is in engaged transmission with the planet gear; and the inner gear ring is fixedly arranged on the output shaft support shell, is positioned onthe outer side of the planet gear, and is in engaged transmission with the planet gear. The submersible planetary reducer is provided with a cooling lubrication loop.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a submersible planetary reducer. Background technique [0002] Aerospace vehicle power systems usually use turbines to drive pumps, compressors and other rotating components. In order to reduce the structural weight of turbine intake and exhaust systems, the existing technology uses a set of ultra-high-speed turbines to simultaneously drive multiple pumps or compressors to rotate. , Different pumps or compressors work at different speeds, and it is necessary to use a reducer to connect with the turbine rotor to output different required speeds. [0003] The aircraft works at a high altitude away from the ground, constrained by the space size and structural weight, the pump or compressor works at a high speed, and its structural size and weight are relatively small, so a reducer connected to the pump or compressor is required It also has a small structural size; the existing reducer is de...
