Rotation apparatus, rotor type compressor applying rotation apparatus, and fluid motor applying rotation apparatus

Abstract

The present invention provides a rotation apparatus, a rotor type compressor applying the rotation apparatus, and a fluid motor applying the rotation apparatus. In the rotation apparatus, a rolling bearing manner is adopted between an eccentric shaft and a rolling piston wheel, reliable sealing of a cylinder is achieved through elastic pre-tightening force, and improvement is performed on a valve rotating body and a valve rotating body reset mechanism.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a rotating device and a rotor compressor and a fluid motor using the same. Background technique [0002] At present, the most commonly used displacement compressors on the market are mainly divided into four types: reciprocating piston compressors, screw compressors, scroll compressors and rotary compressors. For the rotary compressor, when the main shaft rotates, the eccentric rotor rotates close to the inner wall of the cylinder, causing the volume of the crescent-shaped space to change periodically, thereby completing the process of suction, compression and exhaust. Because the compression work of the rotary compressor is smooth, stable and balanced, it has been widely used in household refrigeration equipment such as air conditioners and refrigerators. [0003] figure 1 It is a structural schematic diagram of the first rotary compressor in the prior art. This rotar...

Problems solved by technology

Since the coil spring works under high-strength conditions for a long time, it is very easy to break down and be damaged, which will affect the service life of the entire rotary compressor. It is necessary to find a more sophisticated and reliable swing block reset pressurization mechanism

In addition, due to the leverage, the strength between the swing stopper and the rolling sealing ring 2 is not easy to control. If the strength is too large, it will not only increase the wear of the swing stopper, but also consume the power of the compressor; if the strength is too small, the The sealing of the cylinder cannot be guaranteed

[0007] In addition, where the head of the swing block contacts the outer cylindrical surface of the rolling seal ring 2, it bears a large pressure and has a high-speed relative sliding motion, so it must have low friction, wear resistance, high efficiency, The long-life sealing structure is enough, if there is no corresponding measure, the contact will be easily damaged

However, in most ways, the head of the swing stopper is connected with the contact point of the outer cylindrical surface of the rolling seal ring 2, and the head of the swing stopper is fixed with the position of the outer cylindrical surface of the rolling seal ring. Wear and sealing problems at the contact point, however, it is impossible to achieve rolling between the outer cylindrical surface of the rolling sealing ring 2 and the inner wall of the cylinder of the cylinder body 1, resulting in friction wear and clearance problems

Although oil can be used to fill the gap between the cylinder block and the sealing ring, it brings the problem of subsequent separation of the compressed medium and the oil
