Embodiment 1

[0050] Such as figure 2 and image 3 As shown, the rotor assembly 2 includes a rotor core 10 and an oil deflector 20, wherein the rotor core 10 has a flow channel 11 for the oil-air mixture to flow in; the oil deflector 20 includes a first oil deflector seat 21 and an oil deflector The oil cap 22, the first oil retaining seat 21 is connected to the end face of the rotor core 10, the end face of the oil retaining cap 22 facing the rotor core 10 abuts against the first oil retaining seat 21 to seal the oil retaining cap 22 and the gap between the first oil deflecting seat 21.

[0051] The present application provides a rotor assembly with an oil retaining portion 20, which effectively reduces the oil discharge rate of the compressor on the premise of ensuring the working reliability of the compressor.

[0052] Specifically, by connecting the first oil deflector seat 21 of the oil deflector 20 to the end surface of the rotor core 10, at the same time, the end surface of the oi...

Embodiment 2

[0063] It should be noted that the difference between this embodiment and Embodiment 1 is that, as Figure 12 to Figure 14 As shown, the rotor assembly 2 also includes a second balance weight 40 and an oil shield 50, the second balance weight 40 is connected to the end surface on the other axial side of the rotor core 10; the oil shield 50 is set on the second balance weight The outer peripheral side of 40; the distance from the outer surface of the groove bottom of the receiving groove 221 to the end surface of the oil retaining seat body 211 away from the rotor core 10 is h1, where 0.5mm≤h1≤5mm. In this way, the setting of the oil deflector 50 avoids the sweeping effect of the first balance weight 30, which is beneficial to increase the flow rate of the oil-air mixture entering the flow channel 11 of the rotor core 10 from the lower cavity in the cylinder body 1, and further ensures a large amount of The oil and gas mixture can be separated from the oil and gas in the upper ...

Embodiment 3

[0065] Such as Figure 15 to Figure 20 As shown, the oil deflector 20 also includes a second oil deflector seat 23, the second oil deflector seat 23 is arranged between the first oil deflector seat 21 and the oil deflector cap 22, and the first end of the second oil deflector seat 23 protrudes A plurality of second support columns 231 are arranged in a one-to-one correspondence with the plurality of first support columns 213, and the second end of the second oil deflecting seat 23 abuts against the annular boss 212, The end surface of the second support column 231 abuts against the outer surface of the bottom of the receiving groove 221 . In this way, it is ensured that the compressor has a double-layer oil-repelling structure. In addition, the low-pressure effect between the second oil-repelling seat 23 and the oil-repelling cap 22 is used to introduce the oil-air mixture in the upper cavity of the cylinder 1 into the second oil-repelling seat 23 In the space between oil def...

Abstract

The invention provides a rotor assembly, a motor and a compressor, the rotor assembly comprises a rotor iron core and an oil blocking part, the rotor iron core is provided with a flow channel, and theflow channel is used for an oil-gas mixture to flow in; the oil blocking part comprises a first oil blocking base and an oil blocking cap, the first oil blocking base is connected with the end face of the rotor iron core, and the end face of the side, facing the rotor iron core, of the oil blocking cap abuts against the first oil blocking base so as to block a gap between the oil blocking cap andthe first oil blocking base. The problem that in the prior art, the oil spitting rate of a compressor is too large is solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotor assembly, a motor and a compressor. Background technique [0002] In the prior art, the oil discharge rate of the compressor is one of the factors affecting the energy efficiency and reliability of the compressor. Among them, an excessive oil discharge rate will easily reduce the liquid level of the oil pool of the compressor, causing the oil pool to move Insufficient oil supply to the components reduces the reliability of the compressor. In addition, a large oil discharge rate means a high oil circulation rate, and a large amount of oil circulates in the system and easily reduces the heat exchange efficiency of the system. Contents of the invention [0003] The main purpose of the present invention is to provide a rotor assembly, a motor and a compressor to solve the problem of excessive oil discharge rate of the compressor in the prior art. [0004] In order to a...
