Blade type translation rotor compressor

Abstract

The invention belongs to the technical field of compressors and relates to a blade type translation rotor compressor which comprises a rotor, a cylinder, blades, end covers and a crank, wherein the cylinder is provided with a cylinder hole, the rotor and the blades are arranged in the cylinder hole, the rotor is provided with two flat rotor sliding grooves, the blades are arranged in the rotor sliding grooves and in sliding fit with the rotor sliding grooves, and two side ends of the rotor and the blades are respectively in moving fit with the two end covers arranged at two sides of the cylinder. The blade type translation rotor compressor is characterized in that the cylinder hole of the cylinder is provided with two grooves with planar bottoms, and the two outer ends of the blades respectively correspond to the bottoms of the grooves one to one and are provided with sealing surfaces in moving fit with the bottoms of the grooves. Since the cylinder is not provided with a sliding groove structure and the outer ends of the blades are not in curved surface structures, the manufacturing difficulty of the compressor is reduced.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a rotary rotary compressor, and more specifically to a vane rotary compressor in which the rotor performs translational rotation. Background technique [0002] As we all know, rotary compressors with vane structure features are widely used, including vane compressors with rotary motion, rolling piston compressors with reciprocating blades, and swing rotor compressors with swinging blades, etc. , the traditional vane structure type rotary compressor mostly adopts the working mode of the rotor for rotary motion, so the moving speed of the rotor relative to the end cover and the cylinder is relatively high, which will cause large friction and wear, which is to limit the increase in the speed of the compressor an important obstacle. For this reason, prior art CN101387294B has proposed a kind of translational rotor type compressor, and it comprises rotor, cylinder bod...

AI Technical Summary

Problems solved by technology

The advantage of the above-mentioned translational rotor compressors is that their rotors all adopt translational rotation, so the movement speed of the rotor relative to the cylinder and the end cover is relatively small, and the rotational speed can be increased compared with the traditional vane structure type rotary compressor. , so it can make the volume smaller when the displacement is constant; however, the above-mentioned translational rotor compressor still has shortcomings: 1) such as the compressor proposed by CN101387294B, because it must be in the cylinder A flat cylinder chute is set on the cylinder body, which makes its processing more difficult. In addition, the flat cylinder chute on the cylinder body and the tangential flat body matched with it cause more matching clearances, which also Aggravate the internal leakage of compressor, or its tightness is relatively poor; The outer end of the blade must be made into a curved surface to adapt to the shape of the cylinder bore wall at different positions. Usually, the shape of the outer end of the blade needs to be made into a curved surface combined with multiple arcs, which makes the production of the blade quite difficult. In addition, its end cover rail groove is a curved track groove rail, so the processing of the rail groove is also difficult, and the outer end of the blade can only be sealed in a line contact with the cylinder bore wall, so the sealing reliability is also relatively low.
