Abstract
The invention provides a bearing retainer ring assembly and an aero-engine bearing combined structure. The bearing retainer ring assembly is arranged at the end of a bearing, the bearing retainer ringassembly comprises a bearing retainer ring and an oil blocking cylinder, the bearing retainer ring is fixed on the end surface of the outer ring of the bearing, and a plurality of oil drainage holesare formed in the bearing retainer ring; and the two ends of the oil blocking cylinder are open, the end face of the oil blocking cylinder is fixed to the bearing retainer ring, the inner diameter ofthe oil blocking cylinder is gradually decreased in the direction away from the bearing retainer ring, and the containing space of the bearing communicates with the inner space of the oil blocking cylinder through the oil drainage holes of the bearing retainer ring. According to the bearing retainer ring assembly and the aero-engine bearing combined structure, through the arrangement of the bearing retainer ring with the oil drainage holes and the oil blocking cylinder arranged in the closing-in shape, lubricating oil is prevented from splashing to the position, with too high temperature, of abearing cavity, the phenomena of oil drop coking, ignition and the like are prevented, the service life of the bearing cavity is prolonged, and the working stability and reliability of the aero-engine are improved.
Description
technical field [0001] The invention relates to a bearing retaining ring assembly. [0002] The invention also relates to an aeroengine bearing combination structure. Background technique [0003] Aeroengines are developing in the direction of high thrust-to-weight ratio, high reliability, high durability and low fuel consumption. Bearing cavity and roller bearing are important components of aero-engine, which have a great influence on the reliability of the engine's working performance. With the further increase of the speed of the aero-engine, in order to improve the service life and efficiency of the aero-engine, the design and operation status of the bearing cavity, roller and its accessories of the aero-engine are very important. [0004] Such as figure 1 As shown, the bearing 100 of the aeroengine is arranged between the journal 200 of the engine and the bearing housing 300 for supporting the rotor. When the bearing 100 runs at a high speed, the lubricating oil dro...
