Bearing air cylinder, compressor and air conditioner

Abstract

The invention provides a bearing air cylinder, a compressor and an air conditioner. The bearing air cylinder comprises an outer ring (1), a rolling body (2) and an inner ring (3), the rolling body (2) can be rotatably arranged between the outer ring (1) and the inner ring (3), the outer ring (1) is provided with a screw receding hole (4), a compression medium circulation channel (5) and a lubricating oil circulation channel (6) in the axial direction in a penetrating mode, and the lubricating oil circulation channel (6) is configured to convey lubricating oil to a cavity between the outer ring (1) and the inner ring (3). According to the bearing air cylinder, abnormal abrasion of the bearing air cylinder can be effectively reduced, and the compression energy efficiency of the compressor is improved.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a bearing cylinder, a compressor and an air conditioner. Background technique [0002] The head of the sliding vane and the inner wall of the cylinder of the existing traditional rotary vane compressor are severely worn, resulting in high mechanical power consumption of the compressor, poor overall energy efficiency, and even abnormal wear and other reliability problems in severe cases. [0003] A compressor structure is proposed in the related art. By adopting a bearing cylinder structure, it is ensured that the relative sliding between the head of the slide vane and the inner wall of the inner ring is transformed into a rolling motion between the inner ring and the rolling elements, thereby reducing the mechanical power consumption of the compressor and improving compression. Functional efficiency. However, the unreasonable design of the bearing cylinder structur...
