Rotary Twin Roller Compressor

Abstract

The invention discloses a rotary double-roller compressor, which includes a crankshaft, a cylinder and a motor, and also includes an inner roller sheathed on the crankshaft. There are several structural grooves extending along the circumferential direction of the inner roller between the outer peripheral surface of the inner roller and the inner peripheral surface of the outer roller. During the working process, since there is a structural groove between the outer peripheral surface of the inner roller and the inner peripheral surface of the outer roller, the contact area of ​​the mating surface between the inner roller and the outer roller is effectively reduced, and the two The friction between the inner roller and the outer roller is appropriately reduced, so that there is a moderate relative movement between the inner roller and the outer roller during the operation of the equipment, so that the structural wear between the inner roller and the relevant matching parts of the crankshaft is correspondingly reduced; at the same time, the structure of the above-mentioned groove It is possible to appropriately reduce the overall assembly mass of the inner roller and the outer roller, thereby reducing the load on the motor, so that 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 ...
