Referring to fig. 1 and 2, fig. 1 is a partial schematic view of a compressor according to an embodiment of the present invention, and fig. 2 is a schematic structural view of a rotor casing and a motor casing in fig. 1. The compressor shown in fig. 1 may be a screw compressor, such as an opposed screw compressor. The compressor 100 may include a rotor housing 10, a motor housing 20, a motor 30, and a rotor assembly 40, wherein the motor 30 is in driving connection with the rotor assembly 40 to drive the rotor assembly 40 to rotate, and the rotor assembly 40 may include a first shaft body 41, a first rotor 42, a second shaft body 43, and a second rotor 44. The motor case 20 is detachably mounted at one end in the axial direction of the rotor case 10, thereby enabling formation of a compressor case. The compressor housing may accommodate the first and

second rotors

42 and 44, and the compressor housing may accommodate a portion of the first shaft body 41 and a portion of the second shaft body 43, i.e., the compressor housing has an accommodation space that accommodates the first and

second rotors

42 and 44, a portion of the first shaft body 41, and a portion of the second shaft body 43. It can be understood that the rotor case 10 has a receiving cavity 11, and the rotor assembly 40 is mounted in the receiving cavity 11; the motor case 20 has a mounting cavity 21, and the motor 30 is mounted in the mounting cavity 21. The first shaft body 41 carries the first rotor 42, the second shaft body 43 carries the second shaft body 43, and the rotor case 10 functions to support the first shaft body 41 and the second shaft body 43.

It should be noted that the terms "first", "second", and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

The first rotor 42 and the second rotor 44 are meshed. In an embodiment of the present invention, the first rotor 42 may be a male rotor and the second rotor 44 may be a female rotor.

Here, the first rotor 42 as a male rotor may be understood as a driving rotor, and the second rotor 44 as a female rotor may be understood as a driven rotor, respectively. For example, the first rotor 42 may be drivingly connected to a drive assembly such as the motor 30 (including but not limited to a permanent magnet motor), and the first rotor 42 may be rotated by the motor 30, with the first rotor 42 rotating while simultaneously rotating the second rotor 44.

Referring to fig. 1, the first rotor 42 is carried by the first shaft 41, and is drivingly connected to the motor 30 through the first shaft 41. The motor 30 may drive the first shaft 41 to rotate, and the first shaft 41 may rotate along the first axis of the first shaft 41 together with the first rotor 42 carried by the first shaft 41. I.e. the first rotor 42 can rotate within the rotor housing 10 along the first axis. In the embodiment of the present invention, the first rotor 42 may be integrally formed with the first shaft body 41. In other embodiments of the present invention, a portion of the first rotor 42 may be integrally formed with the first shaft 41, and a portion of the first rotor may be sleeved on the first shaft 41. In other embodiments of the present invention, the first rotor 42 may be directly sleeved on the first shaft 41.

For example, the first rotor 42 may have at least two parts such as the first rotor 42 having a first working portion 421 and a second working portion 422, and both the first working portion 421 and the second working portion 422 may be integrally formed with the first shaft body 41. One of the first working portion 421 and the second working portion 422, such as the first working portion 421, may be integrally formed with the first shaft 41, and the other one, such as the second working portion 422, is sleeved on the first shaft 41. Or the first working part 421 and the second working part 422 are both sleeved on the first shaft 41.

With continued reference to fig. 1, the first working portion 421 and the second working portion 422 of the first rotor 42 may be helical blades, which may also be referred to as male blades. The number of the spiral leaves can be more than one. The first working part 421 and the second working part 422 in the embodiment of the present invention are configured to have opposite spiral directions, i.e., the spiral directions of the first working part 421 and the second working part 422 are opposite. When the first and

second rotors

42, 44 rotate in mesh with each other, an opposite axial force is generated between the first and second working

portions

421, 422, which is also understood to be an opposite axial flow between the first and second working

portions

421, 422. Due to the symmetry of the axial forces, the opposing axial forces generated between the first working portion 421 and the second working portion 422 can be almost cancelled.

It is to be noted that, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

With continued reference to fig. 1, the second rotor 44 is carried by a second shaft body 43, the second shaft body 43 is configured to rotatably support the second rotor 44, and the second rotor 44 can rotate relative to the second shaft body 43. The second rotor 44 is engaged with the first rotor 42 and is driven by the first rotor 42 to rotate on the second shaft body 43 along the second axis of the second shaft body 43. The second rotor 44 may have at least two portions such as the second rotor 44 having a third working portion 441 and a fourth working portion 442, both the third working portion 441 and the fourth working portion 442 being fitted over the second shaft body 43. The third and fourth working

portions

441, 442 are each rotatable within the housing about a second axis.

The third working portion 441 engages with the first working portion 421, and the fourth working portion 442 engages with the second working portion 422. Wherein the rotation direction of the third working portion 441 is opposite to that of the first working portion 421, and the rotation direction of the fourth working portion 442 is opposite to that of the second working portion 422.

The third and fourth working

portions

441, 442 of the second rotor 44 may be helical blades, which may also be referred to as female blades. The number of the spiral leaves can be one or more. The third and fourth working

portions

441, 442 in the present embodiment are configured to have opposite helical directions, i.e., the rotational directions of the third and fourth working

portions

441, 442 are opposite. As the first and

second rotors

42, 44 rotate in mesh with each other, an opposing axial force is generated between the third and fourth working

portions

441, 442, which is also understood to be an opposing axial flow between the third and fourth working

portions

441, 442. Due to the symmetry of the axial forces, the opposing axial forces generated between the third and fourth working

portions

441, 442 can be nearly cancelled.

The first rotor 42 of the embodiment of the present invention includes a first working portion 421 and a second working portion 422, and may mesh with other rotor structures such as the second rotor 44 during the rotation of the first rotor 42, the first working portion 421 of the first rotor 42 meshes with the third working portion 441 of the second rotor 44, and the second working portion 422 of the first rotor 42 meshes with the fourth working portion 442 of the second rotor 44 to form two sets of rotor pairs, compared to the prior art, the meshing of the first rotor 42 and the second rotor 44 of the embodiment of the present invention is equivalent to two screw compressors connected in parallel.
