Abstract
The utility model discloses a but, roll rotor that is used for self-adaptation of compressor, its characterized in that: the rubber ring is arranged between the outer ring of the rolling rotor and the inner ring of the rolling rotor and is fixedly connected with the outer ring of the rolling rotor and the inner ring of the rolling rotor respectively. The utility model has the advantages that the matching of the rolling rotor type structure and the cylinder is interference fit, and the rubber is embedded in the middle, so that the rolling rotor has certain flexibility when being in full circle contact with the inner wall of the cylinder, can be automatically adjusted, can not only not cause jamming, but also greatly reduce gas leakage, thereby improving the efficiency of the compressor; in addition, this rolling rotor is interference fit with the cylinder inner wall, compares prior art and requires greatly reduced to the assembly position degree of cylinder, and the requirement to the cylinder of cylinder inner wall also can reduce simultaneously.
Description
Technical Field
The utility model relates to a rolling rotor formula compressor technical field especially relates to a but rolling rotor of self-adaptation for compressor.
Background
The existing rolling rotor adopts a metal integral structure and is in clearance fit with a cylinder. The clearance of the rolling rotor and the cylinder of the structure has strict requirements, the precision is micron-sized, the cylindricity and the assembly precision of the cylinder hole are required to be very high, the leakage of the compressor with overlarge clearance is large during operation, the efficiency is low, and the running power of the compressor is high or the compressor is blocked due to the undersize clearance or no clearance.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough to above-mentioned prior art exists provides one kind can reduce the assembly precision, but reduces the rolling rotor that is used for the self-adaptation of compressor of leaking.
The utility model discloses the technical scheme who adopts does: an adaptable rolling rotor for a compressor, characterized by: the rubber ring is arranged between the outer ring of the rolling rotor and the inner ring of the rolling rotor and is fixedly connected with the outer ring of the rolling rotor and the inner ring of the rolling rotor respectively.
According to the technical scheme, the outer ring of the rolling rotor and the inner ring of the rolling rotor are connected with the rubber ring in a vulcanization mode.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present embodiment provides an adaptable rolling rotor for a compressor, which includes a rolling rotor outer ring 1, a rubber ring 2 and a rolling rotor inner ring 3, wherein the rubber ring 2 is disposed between the rolling rotor outer ring 1 and the rolling rotor inner ring 3, and is fixedly connected to the rolling rotor outer ring 1 and the rolling rotor inner ring 3, respectively. Specifically, the outer ring 1 of the rolling rotor and the inner ring 3 of the rolling rotor are selected to be connected with the rubber ring 2 by adopting a vulcanized rubber process. The width of the rubber ring is set to be more than or equal to 1 mm. The width of the outer ring of the rolling rotor is as follows: the width of the inner ring of the rolling rotor is: 3.5-4.5mm, preferably 4 mm. In addition, for the convenience of assembly, chamfers are respectively arranged at the upper end and the lower end of the outer ring of the rolling rotor and the inner ring of the rolling rotor.
As shown in fig. 3, a cylindrical hole is provided in the center of the rolling rotor inner ring 3 for connection with the crankshaft 5. The cooperation of this structure rolling rotor 4 and cylinder 6 is interference fit, compares prior art and requires greatly reduced to the fitting position degree of cylinder, and the cylindrical requirement to cylinder inner wall also can reduce simultaneously. And because of the middle rubber, the rolling rotor 4 has certain tolerance when contacting with the inner wall of the cylinder 6 in a whole circle, can be automatically adjusted, cannot cause the blockage, and also can greatly reduce the gas leakage, thereby improving the efficiency of the compressor.
