Problems solved by technology

[0002] Rolling pistons have been used in air compressors, air conditioners, refrigerators and rolling piston engines. Its advantage is that there is no piston connecting rod for linear reciprocating motion; its disadvantages are that the sealing performance of the rolling piston mechanism is poor, and the machining accuracy of parts Extremely high, after the rolling piston assembly wears out, the enlarged gap cannot be automatically compensated, which further increases the leakage of compressed gas

Abstract

The invention provides a sealed structure of a rolling piston compressor or an engine, and relates to the technical field of rolling piston compressors and engines. The sealed structure comprises a cylinder body and a slide block. A power main shaft is provided with a sliding eccentric wheel, and the outside of the sliding eccentric wheel is provided with a rolling sleeve. The sealed structure ismainly characterized in that the sliding eccentric wheel is provided with a radial chute, and the radial chute and sliding surfaces on two sides of the power main shaft are in radial sliding fit; anda clearance is formed between the power main shaft and the top of the radial chute, and the sealed structure is provided with an oil guide structure for connecting the clearance and a hydraulic device. The sealed structure overcomes the defects of the prior art, has the characteristics of unique principle, compact structure and good sealing performance, can greatly increase the efficiency of the compressor or the engine, saves energy, is flexible and convenient to use, and can be widely used in an air compressor, an air conditioner, a refrigerator and a rolling piston engine.

Description

technical field [0001] The invention relates to the technical field of rolling piston compressors and engines. Background technique [0002] Rolling pistons have been used in air compressors, air conditioners, refrigerators and rolling piston engines. Its advantage is that there is no piston connecting rod for linear reciprocating motion; its disadvantages are that the sealing performance of the rolling piston mechanism is poor, and the machining accuracy of parts Extremely high, after the rolling piston assembly is worn, the enlarged gap cannot be automatically compensated, which further increases the leakage of compressed gas. Therefore, improving the structure of the rolling piston, while reducing the machining accuracy of the parts, improving its sealing performance, thereby reducing energy consumption and improving its output function, is a major subject of rolling piston research. Contents of the invention [0003] The purpose of the present invention is to provide ...
