Problems solved by technology

Existing structures such as image 3 The concentricity is ensured through the sliding contact between the radial support pin and the baffle plate. During the adjustment process, the thrust required to overcome the sliding friction is relatively large, and the followability of the adjustment system is poor. Long-term use will cause the baffle plate to wear and affect the reliability of the engine control mechanism.

Abstract

The invention discloses a structure for ensuring the concentricity of a gas compressor control mechanism through rolling contact. The structure comprises an actuating ring, a ball, an anti-abrasion layer, a ball seat and a casing. The ball seat is of a cuboid structure and is fixed to the casing through welding or bolted connecting. A ball socket is formed in the ball seat and internally providedwith the anti-abrasion layer, and the ball is stored in the ball socket. The actuating ring makes contact with the ball surface of the ball, and the actuating ring and the casing are concentrically arranged. According to the technical scheme of the structure, the thrust for friction overcoming is small, the following property of the control mechanism is good, abrasion of long-term use is small, and the reliability of an engine control mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a structure that adopts rolling contact to ensure the concentricity of a compressor control mechanism. Background technique [0002] In the process of adjusting the angle of the adjustable blades, the control mechanism of the aero-engine compressor needs a structure to ensure the concentricity of the actuating ring and the compressor casing. Existing structures such as image 3 The concentricity is ensured through the sliding contact between the radial support pin and the baffle plate. During the adjustment process, the thrust required to overcome the sliding friction is relatively large, and the followability of the adjustment system is poor. Long-term use will cause the baffle plate to wear and affect the reliability of the engine control mechanism. Contents of the invention [0003] In order to solve the above technical problems, the purpose of this invention is to prov...
