Rotary cylinder type revolving compressor

Abstract

The invention discloses a revolving cylinder type rotary compressor, comprising a rotor 1, a cylinder 2, a rotary column 3, a vane 4, a motor rotor 6, a rotating shaft 7, a first end cover 12a and a second end cover 12b; the rotor 1 is arranged in the cylinder 2 in a bias way; the rotor 1 is provided with an arc groove 10; the rotary column 3 is installed in the arc groove 10 and matched with the arc groove 10 in a rotating way; a flat-shaped sliding groove 11 is arranged on the rotary column 3; the internal end of the vane 4 is inserted into the sliding groove 11 and matched with the sliding groove 11 in a sliding way; the external end of the vane 4 is tightly fixed on the inter hole wall of the cylinder 2; the side end of the vane 4 is respectively and tightly fixed on the first end cover 12a and the second end cover 12b, therefore, the size of the cantilever structure of the rotor 1 is shortened, the support rigidity is improved, the percussion strength of the rotor 1 to the cylinder 2 is released, and the impact noise of a compressor is expected to be reduced; in addition, the central part of the first end cover 12a is made into cone hole-shaped structure 13 which is matched with the cone shaft head of the rotating shaft 7, therefore, automatic centering effect can be obtained and the disassembly is convenient, and the coaxiality of the first end cover 12a and the rotating shaft 7 is also ensured.

Description

technical field [0001] The present invention relates to a compressor, in particular to a rotary compressor, more specifically to a rotary cylinder rotary compressor. Background technique [0002] As we all know, vane rotary compressors are widely used in the fields of refrigeration, air conditioning, and air compression because of their small size, light weight, and simple structure. However, there are obvious defects in the traditional sliding vane rotary compressor: on the one hand, the outer end of its sliding vane slides close to the cylinder bore at high speed, resulting in a large mechanical loss; on the other hand, the side end of its sliding vane The use of clearance fit with the end cover results in more internal leakage losses. Then there is a rotary compressor in which the blades are firmly connected to the cylinder and the end cover. The main feature of this compressor is that the rotor, the cylinder, the blades and the end cover all perform rotary motion; the r...
