Embodiment 1

[0027] Such as Figure 1-5 As shown, Embodiment 1 of the present invention provides a compressor rotor, which includes a rotor core 10, the center of the rotor core 10 has a shaft hole, and the shaft hole at the upper end of the rotor core is the first shaft hole 11, adjacent to the first shaft hole 11, extending away from the center of the shaft hole to form a second shaft hole 12, the end of the second shaft hole 12 away from the first shaft hole 11 is the rotor core The third shaft hole 13; the diameter of the second shaft hole 12 is larger than the diameter of the first shaft hole 11 and the diameter of the third shaft hole 13, forming a cavity communicating with the cavity at the upper end of the first shaft hole.

[0028] During the operation of the compressor, the cavity formed inside the rotor iron core of the compressor rotor is used as a negative pressure cavity, and its height is lower, which increases the circulation path of the refrigerant and facilitates the sepa...

Embodiment 2

[0030] The compressor rotor provided by Embodiment 2 of the present invention is optimized on the basis of Embodiment 1, which specifically includes:

[0031] The length of the first shaft hole along the axis is much smaller than the length of the second shaft hole along the axis, so that the rotor core part corresponding to the first shaft hole cooperates with the cavity to form an oil deflecting cap structure.

[0032] In the compressor rotor provided in this embodiment, the structure of the rotor core 10 is changed, and the upper end of the rotor core 10 itself has an oil shield structure, so that there is no need to connect an independent The oil deflecting cap can save the process of riveting the oil deflecting cap and the material cost of the oil deflecting cap, and realize the effect of reducing the oil content of the refrigerant; the compressor rotor of the present invention has a more reasonable structural design of the rotor core, And the structure of the oil deflect...

Embodiment 3

[0034] The compressor rotor provided by Embodiment 3 of the present invention is optimized on the basis of Embodiments 1 and 2, and specifically includes:

[0035] Preferably, the diameter of the first shaft hole 11 is greater than or equal to the diameter of the third shaft hole 13 of the iron core; preferably, the diameter of the first shaft hole 11 is set slightly larger than the third shaft hole 13 diameter to facilitate assembly of the crankshaft.

[0036] Preferably, a counterbore 14 is provided at the lower end of the third shaft hole 13 of the rotor core 10 , and the diameter of the third shaft hole 13 of the rotor core 10 is smaller than the diameter of the counterbore 14 . The above design can make the structural layout of the counterbore 14 and the second shaft hole 12 more reasonable.

[0037] Preferably, the diameter of the second shaft hole 12 is larger than the diameter of the counterbore 14 , and the length of the second shaft hole 12 along the axis is greater...

Abstract

The present invention provides a compressor rotor, which includes a rotor core. The center of the rotor core has a shaft hole. The shaft hole at the upper end of the rotor core is a first shaft hole, which is adjacent to the first shaft hole, A second shaft hole is formed extending away from the center of the shaft hole, and the end of the second shaft hole away from the first shaft hole is the third shaft hole of the rotor core; the diameter of the second shaft hole is larger than The diameter of the first shaft hole and the diameter of the third shaft hole form a cavity communicating with the cavity at the upper end of the first shaft hole. The invention changes the structure of the rotor iron core, and the upper end of the rotor iron core itself has an oil retaining cap, so that there is no need to connect an independent oil retaining cap outside the rotor iron core, and the process of riveting the oil retaining cap and the oil retaining cap can be omitted. The material cost of the cap is reduced, and the effect of reducing the oil content of the refrigerant is achieved. The invention also provides a compressor.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor rotor and a compressor having the same. Background technique [0002] The motor rotor of prior art, for example CN204877962U disclosed compressor and its rotor, the end of its rotor structure is equipped with balance weight, connects oil retaining cap on balance weight; The rotor compressor has a main balance weight at the first end of the rotor core, an auxiliary balance weight at the second end of the rotor core, and a retaining ring at the second end of the rotor core. The ring includes an umbrella-shaped oil deflecting portion and a retaining ring located on the lower end surface of the oil retaining portion, and the retaining ring at least partially shields the magnetic steel groove at the second end of the rotor core. [0003] It can be seen from the content of the above prior art that the oil deflector caps are all riveted on the rotor assembly, and this structure ...
