Rotation type dual-roller compressor

Abstract

The invention discloses a rotation type dual-roller compressor. The rotation type dual-roller compressor comprises a crankshaft, an air cylinder and a motor, and further comprises an inner roller arranged on the crankshaft in a sleeving manner; the periphery of the inner roller is coaxially sleeved with an outer roller, and a plurality of structure grooves extending in the circumferential direction of the inner roller are formed between the outer circumferential face of the inner roller and the inner circumferential face of the outer roller. In the working process, as the structure grooves are formed between the outer circumferential face of the inner roller and the inner circumferential face of the outer roller, the fit face contact area between the inner roller and the outer roller is effectively reduced, the friction force between the inner roller and the outer roller is appropriately reduced, and the moderate relative motion exists between the inner roller and the outer roller in the equipment running process so as to correspondingly reduce structure abrasion between related fit parts of the inner roller and the crankshaft; meanwhile, due to the existence of the above structure grooves, the total assembly mass of the inner roller and the outer roller can be appropriately reduced, the motor load is accordingly reduced, and the overall energy consumption of the compressor is correspondingly reduced.

Description

technical field [0001] The invention relates to the technical field of compressor supporting equipment, in particular to a rotary double-roller compressor. Background technique [0002] Rotary compressors are an essential part of electrical equipment that requires refrigeration such as air conditioners and refrigerators. Rotary double-roller compressors are a relatively common type of rotary compressor. With the continuous improvement of use requirements, Its working performance has also been paid more and more attention by people. [0003] At present, during the assembly and use of the existing rotary double-roller compressor, due to the large contact area and high friction coefficient between the two rollers of the coaxial sleeve, the friction between the two rollers during the operation of the compressor There is almost no relative movement, which increases the structural wear of the inner roller and the eccentric circle of the crankshaft; in addition, the total mass of ...

[0003] At present, during the assembly and use of the existing rotary double-roller compressor, due to the large contact area and high friction coefficient between the two rollers of the coaxial sleeve, the friction between the two rollers during the operation of the compressor There is almost no relative movement, which increases the structural wear of the inner roller and the eccentric circle of the crankshaft; in addition, the total mass of the existing double-roller structure is relatively large, which increases the load on the motor, thus reducing the overall energy consumption of the compressor. increase accordingly
