A bearing seat structure that can effectively reduce the temperature of the bearing cavity

Abstract

The invention relates to a bearing seat structure capable of effectively reducing the temperature of a bearing cavity. The bearing seat comprises a cylindrical extension part, the cylindrical extension part is integrally formed with a bearing seat body, and the cylindrical extension part is arranged on the front side of the bearing seat body; the front end face of the cylindrical extension part is formed into a flange connecting end face, and the flange connecting end face is connected with the coordination end face of another disc-shaped bearing seat through bolts; therefore, basically, the bearing cavity is defined by the cylindrical extension part, the bearing seat body, the disc-shaped bearing seat and an engine rotating shaft, and the cylindrical extension part constitutes the outer wall of the bearing cavity; multiple through hole structures which run through the whole bearing seat in the axial direction are arranged on the annular wall of the cylindrical extension part in the circumferential direction, and can wrap the bearing cavity in the circumferential direction at least basically. The bearing seat structure can effectively reduce the temperature inside the bearing cavity, improve the cooling effect of grease, and can make the work environment of a bearing improved to extend the life of the bearing.

Description

technical field [0001] The invention relates to the fields of ground gas turbines and aero-engines, and in particular to a bearing seat structure that can effectively reduce the temperature of a bearing cavity. By adopting the new bearing seat structure, the working environment of the internal bearing of the engine can be optimized, the lubricating oil system in the engine can be improved, and the lubrication effect can be improved. , reduce the temperature of the bearing cavity, improve the safety of the engine, and then improve the competitiveness of the engine. Background technique [0002] In ground gas turbines and aero engines, bearings are one of the essential key components of the engine. They mainly support other parts of the engine and bear a certain axial force. During this process, lubricating the bearing is the most basic and most important link to ensure the safe and reliable operation of the bearing. Lubricating oil can reduce the friction and wear of the bea...

Problems solved by technology

However, in the previous engine structure, the usual practice is to keep the bearing cavity as far away as possible from the turbine flow channel of the engine, or to add other structures to further surround the bearing housing that wraps the bearing cavity, increasing the heat transfer resistance

However, these methods often increase the size of the engine, or increase the number of parts, and increase the cost of the engine, and for micro gas turbines or aero engines, these methods will be more limited
