Vortex compressor

Abstract

This invention relates a whirlpool compressor, which is to realize the none-oil lubricating of the compressor and reduce the tipping toque on the stirring whirlpool plate produced from the gas power and the centrifugal inertia force, and increases the working stability of the compressor, and prolongs the life the driving bearing. The defending self-rotating structure is composed of the stirring whirlpool plate (4), the small wrist joint (6), the bearing (7), and the bearing embedded clamp (8), wherein the top of the small wrist joint (6) is embedded at the end plate of the stirring whirlpool plate (4) through the bearing (7), and the under part of the small wrist joint (6) is mounted in the bearing embedded clamp (8), and he bearing embedded clamp (8) is mounted on the frame. The driving bearing (5) is embedded in the central part of the stirring whirlpool plate. Wherein the self-lubricating material (10) is arranged on the whirlpool plate surface that connects with the stirring whirlpool plate (4) and the bearing embedded clamp (8), and the self-lubricating material (9) is arranged on the connecting surface of the static whirlpool plate (3) and the stirring whirlpool plate (4).

Description

technical field [0001] The invention relates to a scroll compressor in a fluid displacement machine. Background technique [0002] The main components of the scroll compressor are: movable scroll, fixed scroll, bracket body, crankshaft, motor, etc. The profiles of the movable and static scrolls are exactly the same, and the phases are eccentrically arranged by 180°. The movable and static scrolls are meshed to form a closed compression chamber, and the medium is gradually compressed from the outside to the inside to realize suction, compression and exhaust. In the usual scroll compressor structure, each friction pair is lubricated by oil injection, and the movable scroll drive bearing is placed outside the movable scroll disc. This structure is due to the difference between the gas force acting plane and the moving scroll centrifugal force acting plane. The driving planes of the movable scroll are not coplanar, resulting in an overturning moment to the movable scroll, resul...

AI Technical Summary

Problems solved by technology

In the usual scroll compressor structure, each friction pair is lubricated by oil injection, and the movable scroll drive bearing is placed outside the movable scroll disc. This structure is due to the difference between the gas force acting plane and the moving scroll centrifugal force acting plane. The driving planes of the movable scroll are not coplanar, resulting in an overturning moment against the movable scroll, resulting in unstable working conditions of the compressor and shortened service life, and oil is contained in the oil-lubricated compression medium, which limits its use.
