Problems solved by technology

[0003] The purpose of the present invention is to provide a rolling rotor compressor, which has a radially flexible mechanism to solve the problem of the relationship between the rollers in the pump body, such as the crankshaft and the sliding vane, when the rolling rotor compressor is under severe working conditions or high-speed operation. Excessive local contact stress between other parts, etc. leads to the problem of roller wear and compressor reliability decline

Abstract

The invention provides a rolling rotor type compressor. A pump body of the rolling rotor type compressor comprises a crankshaft, an upper flange, an air cylinder, a lower flange, a roller and a slip sheet, wherein radial flexible mechanisms are respectively or simultaneously arranged on the crankshaft, the roller and / or the slip sheet. The radial flexible mechanism on the crankshaft is a crescent flexible slot. The radial flexible mechanism on the roller is a ring-shaped flexible slot. The radial flexible mechanism on the slip sheet is a flexible hole. According to the rolling rotor type compressor provided by the invention, the radial flexible mechanisms are arranged on components such as the crankshaft, the roller, the slip sheet and the like. Setting positions of the radial flexible mechanisms are contact positions / stress concentration positions in a component working state; by virtue of flexible deformation of the radial flexible mechanisms, local contact stress among components can be reduced or stress concentration parts are transferred, so that effects and purposes of reducing abrasion, prolonging service lives of the components are achieved.

Description

technical field [0001] The invention relates to a rolling rotor compressor, in particular to a rolling rotor compressor with a radial flexible mechanism, which belongs to the technical field of air conditioning equipment. Background technique [0002] At present, the rolling rotor compressors used in air conditioners generally adopt a high back pressure design scheme, and the sliding vanes are in contact with the rollers under the action of back pressure (high pressure), so wear occurs during relative motion. When the operating conditions are harsh or high-speed operation, the contact wear between the rollers and other parts such as sliding plates and crankshafts is serious. With the expansion of air-conditioning application fields, especially with the application of air-conditioning systems in high-temperature areas, this problem has become increasingly prominent. In the field of air-conditioning equipment technology, low back pressure design schemes have been proposed to ...
