[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0052] An embodiment of the present invention provides a compressor, which may be a screw compressor, a scroll compressor, etc., and may be applied to fluid machinery such as air conditioners.

[0053] refer to Figure 1 and Figure 2 , Figure 1 A partial structural schematic diagram of a first compressor provided by an embodiment of the present invention; Figure 2 A schematic diagram of the cooperation between a first rotor, a second rotor, a first shaft and a second shaft in a compressor provided in an embodiment of the present invention.

[0054] The embodiment of the present invention provides a compressor 100, which includes a first shaft body 10, a first rotor 20, a second shaft body 30, a second rotor 40 and a housing 50. The first shaft body 10 and the second shaft body 30 are arranged in parallel with each other in the housing 50, the first rotor 20 is arranged on the first shaft body 10, the second rotor 40 is arranged on the second shaft body 30, a certain gap is reserved between the first rotor 20 and the housing 50, and a certain gap is also reserved between the second rotor 40 and the housing 50.

[0055] The first rotor 20 and the second rotor 40 are meshed. In some embodiments, the first rotor 20 may be a male rotor, and the second rotor 40 may be a female rotor. The first rotor 20 as a male rotor may be understood as the first rotor 20 being an active rotor, and the second rotor 40 as a female rotor may be understood as the second rotor 40 being a driven rotor. The first rotor 20 may be transmission-connected to the motor 60, so that the first rotor 20 may be driven to rotate by the motor 60, and the first rotor 20 may rotate while driving the second rotor 40 to rotate together through meshing.

[0056] In some embodiments, the first rotor 20 is carried by the first shaft body 10, and the first shaft body 10 is configured to rotatably support the first rotor 20, and the first rotor 20 can rotate relative to the first axis 11 of the first shaft body 10. Under the meshing action of the first rotor 20 and the second rotor 40, the second rotor 40 can be driven by the first rotor 20 to rotate on the second shaft body 30 along the second axis 31 of the second shaft body 30. The first rotor 20 includes a first portion 21 and a second portion 22 with opposite thread rotation directions, the first portion 21 is sleeved on the first shaft body 10, and the second portion 22 is integrally formed with the first shaft body 10, and the first portion 21 and the second portion 22 can rotate around the first axis 11 in the housing 50.

[0057] It should be noted that the end face of the first part 21 close to the second part 22 is the first air intake end face 201, and the end face of the first part 21 away from the second part 22 is the first air discharge end face 202. The end face of the second part 22 close to the first part 21 is the second air intake end face 203, and the end face of the second part 22 away from the first part 21 is the second air discharge end face 204, and a gap is reserved between the first air intake end face 201 and the second air discharge end face 204.

[0058] Continue reading Figure 1 and Figure 2The second rotor 40 is carried by the second shaft body 30, and the second rotor 40 can rotate in the housing 50 along the second axis 31. In some embodiments of the present invention, the second rotor 40 is sleeved on the second shaft body 30. Exemplarily, the second rotor 40 includes a third portion 41 and a fourth portion 42 with opposite thread rotation directions, the third portion 41 is configured to be at least partially adapted to mesh with the first portion 21, and the fourth portion 42 is configured to be at least partially adapted to mesh with the second portion 22. The thread rotation directions of the third portion 41 and the first portion 21 are opposite, and the thread rotation directions of the fourth portion 42 and the second portion 22 are opposite.

[0059] In the embodiment of the present application, the first rotor 20 and the second rotor 40 are arranged in parallel in the housing 50. The first shaft body 10 has a first end 12 and a second end 13, the first end 12 is fixed to the housing 50, the second end 13 is drivingly connected to the motor 60, and the first part 21 and the second part 22 are limited between the first end 12 and the second end 13. The second shaft body 30 has a third end 32 and a fourth end 33, the third end 32 and the fourth end 33 are respectively fixed to the housing 50, and the third part 41 and the fourth part 42 are limited between the third end 32 and the fourth end 33.

[0060] When the first rotor 20 and the second rotor 40 mesh and rotate, the first part 21 generates a first axial force, and the second part 22 generates a second axial force. Since the first part 21 and the second part 22 are symmetrically arranged and rotate in opposite directions, theoretically, the first axial force and the second axial force are equal in magnitude and opposite in direction, so that the first axial force and the second axial force can offset each other. Similarly, the third axial force and the fourth axial force can also offset each other in theory. In actual use, the compressor 100 may have an axial force instability problem at the moment of power on and off. Since the first part 21 and the second part 22 can rotate relative to the first shaft 10, the positions of the first part 21 and the second part 22 will move at the moment of power on and off, and the first part 21 and / or the second part 22 may collide with the housing 50.

[0061] Based on this, the compressor 100 provided in the embodiment of the present invention is further provided with a first spacer 71, and the first spacer 71 is detachably connected to the housing 50. When the first spacer 71 is worn or damaged, the first spacer 71 can be replaced to ensure that a stable gap is always maintained between the first rotor 20 and the housing 50, thereby preventing the first rotor 20 from colliding or wearing with the housing 50, thereby improving the stability of the compressor 100.

[0062] Please combine Figure 1 and Figure 2 And refer to Figure 3 and Figure 4 , Figure 3A first partial structural diagram of a first spacer and a housing provided in an embodiment of the present invention; Figure 4 A second partial structural diagram of the first spacer and the shell provided in an embodiment of the present invention.

[0063] A first accommodating cavity 51 is provided on one side of the shell 50 facing the first part 21 , a portion of the first spacer 71 is located in the first accommodating cavity 51 , another portion of the first spacer 71 is located between the first part 21 and the shell 50 , and the first spacer 71 can be removed from the first accommodating cavity 51 .

[0064] In some embodiments, the end of the housing 50 facing the first portion 21 is provided with a first threaded hole 511, and the end of the first spacer 71 facing the housing 50 is provided with a first threaded column 711, and the first threaded hole 511 cooperates with the first threaded column 711 to connect the first spacer 71 to the housing 50. When the first spacer 71 is worn or damaged, the first spacer 71 can be removed from the housing 50 and replaced by screwing the first spacer 71, so that the distance between the first spacer 71 and the end of the first portion 21 remains stable, thereby preventing the first rotor from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0065] In some embodiments, the housing 50 is provided with a second threaded column 512 at the end facing the first portion 21, and the first spacer 71 is provided with a second threaded hole 712 at the end facing the housing 50, and the second threaded hole 712 cooperates with the second threaded column 512 to connect the first spacer 71 to the housing 50. When the first spacer 71 is worn or damaged, the first spacer 71 can be removed from the housing 50 and replaced by screwing the first spacer 71, so that the distance between the first spacer 71 and the end of the first portion 21 remains stable, thereby preventing the first rotor from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0066] It is understandable that the first spacer 71 may also be completely protruded from the first accommodating cavity 51. In addition, the first spacer 71 may also be disposed at other locations, such as: the surface of the housing 50, the surface of the first portion 21, between the first portion 21 and the housing 50, etc., as long as at least part of the first spacer 71 is disposed between the first portion 21 and the housing 50.

[0067] In addition, the detachable connection between the first spacer 71 and the housing 50 may also be in other connection modes, such as a snap-on mode. In practical applications, the first spacer 71 may be worn or deformed due to the long-term operation of the first rotor 20, causing the distance between the first spacer 71 and the first part 21 to change. At this time, the collision between the first rotor 20 and the first spacer 71 and the first rotor 20 and the housing 50 is relatively large, which may affect the performance and stability of the compressor 100. Therefore, the compressor 100 provided in the embodiment of the present invention is also provided with a distance sensor for detecting the distance between the first spacer 71 and the end of the first part 21. When the first distance sensor 91 detects that the distance value d1 between the first spacer 71 and the end of the first part 21 is different from the threshold range of the preset distance, an alarm signal will be issued to remind the user that the first spacer 71 has reached the degree of damage and needs to be replaced, so as to prevent the first rotor 20 from colliding with the housing and affecting the stability of the compressor 100.

[0068] Please refer to Figures 5 to 7 , Figure 5 A partial structural schematic diagram of a second compressor provided by an embodiment of the present invention; Figure 6 A first partial structural diagram of a second spacer and a housing provided in an embodiment of the present invention; Figure 7 A second partial structural diagram of a second spacer and a shell provided in an embodiment of the present invention.

[0069] In another embodiment of the present invention, the compressor 100 may further be provided with a second spacer 72, and the second spacer 72 may be detachably connected to the housing 50. When the second spacer 72 is worn or damaged, the second spacer 72 may be replaced so that a stable gap is always maintained between the second rotor 40 and the housing 50, thereby preventing the second rotor 40 from colliding or wearing with the housing 50, thereby improving the stability of the compressor 100.

[0070] A second accommodating cavity 52 is provided on the side of the shell 50 facing the fourth part 42 , a portion of the second spacer 72 is located in the second accommodating cavity 52 , another portion of the second spacer 72 is located between the fourth part 42 and the shell 50 , and the second spacer 72 can be removed from the second accommodating cavity 52 .

[0071] In some embodiments, the end of the housing 50 facing the fourth portion 42 is provided with a third threaded hole 521, and the end of the second spacer 72 facing the housing 50 is provided with a third threaded column 721, and the third threaded hole 521 cooperates with the third threaded column 721 to connect the second spacer 72 to the housing 50. When the second spacer 72 is worn or damaged, the second spacer 72 can be removed from the housing 50 and replaced by screwing the second spacer 72, so that the distance between the second spacer 72 and the end of the fourth portion 42 remains stable, thereby preventing the second rotor 40 from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0072] In some embodiments, the housing 50 is provided with a fourth threaded column 522 at the end facing the fourth portion 42, and the second spacer 72 is provided with a fourth threaded hole 722 at the end facing the housing 50, and the fourth threaded hole 722 cooperates with the fourth threaded column 522 to connect the second spacer 72 to the housing 50. When the second spacer 72 is worn or damaged, the second spacer 72 can be removed from the housing 50 and replaced by screwing the second spacer 72, so that the distance between the second spacer 72 and the end of the fourth portion 42 remains stable, thereby preventing the second rotor 40 from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0073] It is understandable that the second spacer 72 may also completely protrude from the second accommodating cavity 52. ​​In addition, the second spacer 72 may also be disposed at other locations, such as: the surface of the housing 50, the surface of the fourth portion 42, between the fourth portion 42 and the housing 50, etc., as long as at least part of the second spacer 72 is disposed between the fourth portion 42 and the housing 50.

[0074] In addition, the detachable connection between the first spacer and the housing 50 may also be in other connection modes, such as a snap-fit ​​connection mode.

[0075] In actual application, the second spacer 72 may be worn or deformed due to the long-term operation of the second rotor 40, causing the distance between the second spacer 72 and the fourth part 42 to change. At this time, the collision between the second rotor 40 and the second spacer 72 and the second rotor 40 and the housing 50 is relatively large, which may affect the performance and stability of the compressor 100. Therefore, the compressor 100 provided in the embodiment of the present invention is also provided with a second distance sensor 92 for detecting the distance between the second spacer 72 and the end of the fourth part 42. When the second distance sensor 92 detects that the distance value d2 between the second spacer 72 and the end of the fourth part 42 is different from the threshold range of the preset distance, an alarm signal will be issued to remind the user that the second spacer 72 has reached the degree of damage and needs to be replaced, so as to prevent the second rotor 40 from colliding with the housing 50 and affecting the stability of the compressor 100.

[0076] Please refer to Figures 8 to 10 , Figure 8 A partial structural schematic diagram of a third compressor provided in an embodiment of the present invention, Fig. 9 A first partial structural diagram of a third spacer and a housing provided in an embodiment of the present invention, Fig.10 A second partial structural diagram of a third spacer and a shell provided in an embodiment of the present invention.

[0077] In the third embodiment of the present invention, the compressor 100 may further be provided with a third spacer 73, and the third spacer 73 may be detachably connected to the housing 50. When the third spacer 73 is worn or damaged, the third spacer 73 may be replaced so that a stable gap is always maintained between the first rotor 20 and the housing 50, thereby preventing the first rotor 20 from colliding or wearing with the housing 50, thereby improving the stability of the compressor 100.

[0078] A third accommodating cavity 53 is provided on one side of the shell 50 facing the second part 22 , a portion of the third spacer 73 is located in the third accommodating cavity 53 , another portion of the third spacer 73 is located between the second part 22 and the shell 50 , and the third spacer 73 can be removed from the third accommodating cavity 53 .

[0079] In some embodiments, the end of the housing 50 facing the second portion 22 is provided with a fifth threaded hole 531, and the end of the third spacer 73 facing the housing 50 is provided with a fifth threaded column 731, and the fifth threaded hole 531 cooperates with the fifth threaded column 731 to connect the third spacer 73 to the housing 50. When the third spacer 73 is worn or damaged, the third spacer 73 can be removed from the housing 50 and replaced by screwing the third spacer 73, so that the distance between the third spacer 73 and the end of the second portion 22 remains stable, thereby preventing the first rotor 20 from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0080] In some embodiments, the end of the housing 50 facing the second portion 22 is provided with a sixth threaded column 532, and the end of the third spacer 73 facing the housing 50 is provided with a sixth threaded hole 732, and the sixth threaded column 532 cooperates with the sixth threaded hole 732 to connect the third spacer 73 to the housing 50. When the third spacer 73 is worn or damaged, the third spacer 73 can be removed from the housing 50 and replaced by screwing the third spacer 73, so that the distance between the third spacer 73 and the end of the second portion 22 remains stable, thereby preventing the first rotor 20 from colliding or wearing with the housing 50, thereby affecting the stability of the compressor 100.

[0081] It is understandable that the third spacer 73 may also be entirely protruded from the third accommodating cavity 53. In addition, the third spacer 73 may also be disposed at other locations, such as: the surface of the housing 50, the surface of the second portion 22, between the second portion 22 and the housing 50, etc., as long as at least part of the third spacer 73 is disposed between the second portion 22 and the housing 50.

[0082] In addition, the detachable connection between the third spacer and the housing 50 may also be in other connection modes, such as a snap-fit ​​connection mode.

[0083] In addition, the compressor 100 provided in the embodiment of the present invention is further provided with a third distance sensor 93 for detecting the distance between the third spacer 73 and the end of the second portion 22. When the third distance sensor 93 detects that the distance value d3 between the third spacer 73 and the end of the second portion 22 is different from the threshold range of the preset distance, an alarm signal is issued to remind the user that the third spacer 73 has reached the degree of damage and needs to be replaced, so as to prevent the first rotor 20 from colliding with the housing 50 and affecting the stability of the compressor 100.

[0084] It should be noted that the first spacer 71 and the third spacer 73 of the embodiment of the present application are respectively located on both sides of the first rotor 20. At this time, the combined force of the impact force on both sides can be controlled to a smaller value through the casting processing and assembly process, so that the spacer alone can be used for load limiting, thereby eliminating the thrust bearing.

[0085] It should be noted that the materials of the first spacer 71, the second spacer 72 and the third spacer 73 can be soft materials, such as peek materials, etc., and the hardness of the materials of the first spacer 71, the second spacer 72 and the third spacer 73 only needs to be lower than the hardness of the material of the housing 50 and the hardness of the materials of the first rotor 20 and the second rotor 40. The embodiment of the present invention does not specifically limit the shapes of the first spacer 71, the second spacer 72 and the third spacer 73, and they can be selected according to actual needs.

[0086] Similarly, a spacer may be disposed between the third portion 41 and the housing 50 , and the spacer and the housing 50 may be detachably connected.

[0087] The compressor 100 provided in an embodiment of the present invention has a first spacer 71 disposed between the first rotor 20 and the housing 50. The first spacer 71 is detachably connected to the housing 50. Therefore, the first spacer 71 can be disassembled and replaced, so that a stable gap can be always maintained between the first rotor 20 and the housing 50, thereby avoiding collision or wear between the first rotor 20 and the housing 50, thereby improving the stability of the rotor system and the compressor 100.
