A Safe and Reliable Bearing Block for Aeroengine

Abstract

The invention relates to a safe and reliable bearing seat for an aero-engine, comprising a bearing seat body, a shaft hole is arranged on the bearing seat body, a plurality of protruding claws are evenly distributed on the tail end edge of the shaft hole, and each protruding claw is integrally formed with the bearing seat body. , each claw includes a first radially extending portion, a second radially extending portion and a bent portion, the first radially extending portion extends from the edge of the shaft hole to the center of the shaft hole, and the bottom end of the first radially extending portion extends outward Out of the tail end of the shaft hole, the second radially extending part is arranged along the radial direction of the shaft hole and the bottom end of the second radially extending part is connected with the top outside of the first radially extending part, so that the second radially extending part Placed outside the tail end of the shaft hole, the bottom end of the bent part is connected to the second radially extending part, and the top end of the bent part extends toward the front end of the shaft hole, so that the bent part, the second radially extending part and the V-shaped engagement grooves are formed between the first radially extending portions.

Description

technical field [0001] The invention relates to the technical field of aero-engine auxiliary equipment, in particular to a bearing seat for an aero-engine. Background technique [0002] In a turboshaft engine, it is necessary to support the main bearing of the engine, that is, the front bearing of the axial flow compressor. In the prior art, the bearing seat is not easy to handle during assembly, either because there is no point of force on the bearing seat, or simply setting along the Although the radially extending claws can exert force, they interfere with the bearing cage and affect the safety of the engine. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a bearing housing for an aero-engine with simple structure, safety and reliability. [0004] In order to solve the above-mentioned technical problems, the bearing seat for an aero-engine provided by the present invention includes a bearing seat body, and a shaft ho...
