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.
