AI Technical Summary
During operation, existing rotary compressors produce high-temperature gas due to friction and compression work, which leads to an increase in the internal temperature of the compressor, which may cause automatic quitting and affect the service life.
An oil barrier ring is installed at the upper end of the rotor, and an axial flow fan is provided in the central hole of the oil barrier ring. The axial flow fan is composed of a central rod and a uniformly distributed fan blade. When the rotor rotates, the axial flow fan accelerates the high-temperature gas flowing upwards and discharges it out of the compressor.
By accelerating the upward flow of high-temperature gas, the internal temperature of the compressor is effectively reduced, and the reliability and service life of the compressor are increased.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary compressors, in particular to a novel rotor and a rotary compressor. Background Art
[0002] Existing rotary compressors such as Figure 4 As shown, it includes a shell, and a motor is installed at the upper end of the shell. The motor consists of a stator 4 and a rotor 1. The rotor is connected to the mechanical structure below. The mechanical structure mainly includes a cylinder and a crankshaft 5. The crankshaft 5 is fixedly connected to the crankshaft hole in the center of the rotor 1. During operation, the mechanical structure below generates high-temperature gas due to friction and compression work, causing the internal temperature of the compressor to rise. When the temperature is too high, the compressor may automatically trip, which will affect the service life of the compressor. Summary of the invention

[0005] Furthermore, the axial flow fan is provided with six fan blades.
[0006] Furthermore, the oil retaining ring is connected to the rotor body through rivets.
[0007] The utility model also provides a rotary compressor equipped with the novel rotor. When the rotor rotates, the axial flow fan rotates together with the rotor so that the high-temperature gas below the axial flow fan is accelerated to flow upward.
[0008] Compared with the prior art, the utility model has the following advantages: by adding an axial flow fan in the oil retaining ring at the upper end of the rotor on the basis of the original rotor structure, when the compressor is running, the high-temperature gas below can flow upward faster and be discharged from the compressor, thereby achieving the purpose of reducing the temperature of the compressor, increasing the reliability of the compressor, and improving the service life of the compressor.
