Double-thrust self-balancing uniform-load structure bearing for high-speed rotor

Abstract

The invention belongs to the field of engineering machinery design, and particularly relates to a double-thrust self-balancing uniform-load structure bearing for a high-speed rotor. A double-thrust self-balancing uniform-load structure bearing for a high-speed rotor comprises a feedback assembly, a front balance block, a front thrust pad, a bearing copper alloy, the rotor, a rear balance block and a rear thrust pad, the inner edge of the front end of the feedback assembly is in press fit with the front balance block, the outer edge of the rear end of the feedback assembly is in press fit with the rear balance block, the front balance block tightly presses the front thrust pad, and the rear balance block tightly presses the rear thrust pad. The rear balance block compresses the rear thrust pad, and the surfaces, attached to the rotor, of the front thrust pad and the rear thrust pad are plated with bearing copper alloy. The double-thrust self-balancing structure avoids the limitation that an existing thrust bearing can only bear thrust through a single thrust surface, optimizes the structural size, meets the rotor operation requirements of strict structural size requirements, large load and high rotating speed, and has wide application value.

Description

technical field [0001] The invention belongs to the field of construction machinery design, and in particular relates to a double-thrust self-balancing load-sharing structural bearing for a high-speed rotor. Background technique [0002] Nowadays, the air force and navy have more and more requirements on equipment, and have higher requirements on overall design and structural size. How to increase the axial load force of thrust bearings in a limited space is an urgent problem to be solved. Commonly used thrust bearings can only withstand axial thrust through a single thrust surface. In order to increase the axial thrust bearing capacity of the bearing, it is often necessary to increase the axial dimension, which will lead to an increase in linear velocity. In response to such problems, the current research mainly focuses on how to increase the load per unit area of ​​the thrust bearing. The performance can only be improved by changing the structure or the bearing alloy mater...

Problems solved by technology

Commonly used thrust bearings can only withstand axial thrust through a single thrust surface. In order to increase the axial thrust bearing capacity of the bearing, it is often necessary to increase the axial dimension, which will lead to an increase in linear velocity

In response to such problems, the current research mainly focuses on how to increase the load per unit area of ​​the thrust bearing. The performance can only be improved by changing the structure or bearing alloy material, which has great limitations and limited room for improvement.
