[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Hereinafter, with reference to the accompanying drawings, a Cross ring 100 of a compressor according to an embodiment of the present invention will be described.

[0037] like Figure 1-Figure 7 As shown, the cross slip ring 100 of the compressor according to the embodiment of the utility model includes: a ring body 1 and a plurality of limit keys 2, the plurality of limit keys 2 include a pair of first keys 21 and a pair of second keys 22, the first keys 21 and the second keys 22 both protrude from the ring body 1, the pair of first keys 21 are used to cooperate with the fixed parts of the compressor, the pair of second keys 22 are used to cooperate with the movable scroll parts of the compressor, at least a portion of the outer peripheral wall of the first key 21 is formed as an arc surface and / or at least a portion of the outer peripheral wall of the second key 22 is formed as an arc surface.

[0038] Therefore, the friction resistance of the movable scroll component during the movement can be reduced, the power loss can be reduced, and the impact load and vibration noise can be reduced, thereby improving the practicality of the Cross ring 100.

[0039] First, if Figure 1-Figure 5 As shown, the compressor includes an Oldham ring 100, a movable scroll component and a fixed component. The Oldham ring 100 cooperates with the movable scroll component and the fixed component respectively to limit the movable scroll component from rotating axially around itself relative to the fixed component.

[0040] It should be noted that the movable scroll component may be the movable scroll 200, and the fixed component may be the bracket 300; or, the movable scroll component may be the movable scroll 200, and the fixed component may be the fixed scroll, which is not limited in the present application.

[0041] The cross slip ring 100 includes a ring body 1 and a plurality of limit keys 2. The ring body 1 is formed into a circular ring shape. The plurality of limit keys 2 are arranged at intervals along the circumference of the ring body 1. The plurality of limit keys 2 include a pair of first keys 21 and a pair of second keys 22. The first keys 21 and the second keys 22 both protrude from the ring body 1. The two first keys 21 are respectively arranged on opposite sides of the ring body 1 in the radial direction, and the two second keys 22 are respectively arranged on opposite sides of the ring body 1 in the radial direction, and the two first keys 21 and the two second keys 22 can be arranged in a cross shape.

[0042] The fixed component is provided with two first guide grooves 301, and the two first keys 21 are used to extend into the two first guide grooves 301 respectively to cooperate with the fixed component guidance. The movable scroll component is provided with two second guide grooves 201, and the two second keys 22 are used to extend into the two second guide grooves 201 respectively to cooperate with the movable scroll component guidance, so that the fixed component can guide and limit the movable scroll component through the cross slip ring 100 to limit the movable scroll component from rotating axially relative to the fixed component around its own axis.

[0043] Among them, at least a portion of the outer peripheral wall of the first key 21 can be formed as an arc-shaped surface; or, at least a portion of the outer peripheral wall of the second key 22 can be formed as an arc-shaped surface; or, at least a portion of the outer peripheral wall of the first key 21 can be formed as an arc-shaped surface, and at least a portion of the outer peripheral wall of the second key 22 can be formed as an arc-shaped surface, and the present application does not impose any restrictions on this.

[0044] It can be understood that by providing an arcuate surface on the outer peripheral wall of the first key 21, the first key 21 can be directly guided and matched with the first guide groove 301 through the arcuate surface, which is beneficial to reducing the friction area between the first key 21 and the first guide groove 301, and by providing an arcuate surface on the outer peripheral wall of the second key 22, the second key 22 can be directly guided and matched with the second guide groove 201 through the arcuate surface, which is beneficial to reducing the friction area between the second key 22 and the second guide groove 201, reducing the friction resistance of the movable scroll component during movement, reducing power loss, and because there is a line contact between the arcuate surface and the first guide groove 301 (second guide groove 201), the impact load caused by the change of the meshing angle can be avoided, greatly reducing the impact load and vibration noise.

[0045] In addition, since the first key 21 and the second key 22 can be directly matched with the corresponding guide grooves, there is no need to provide an additional guide bearing, which can simplify the structure of the cross ring 100.

[0046] According to the Cross ring 100 of the compressor of the embodiment of the utility model, by setting at least a portion of the outer peripheral wall of the first key 21 to be formed as an arc surface and / or setting at least a portion of the outer peripheral wall of the second key 22 to be formed as an arc surface, the friction resistance encountered by the movable scroll component during movement can be reduced, power loss can be reduced, and impact load and vibration noise can be reduced, thereby improving the practicality of the Cross ring 100.

[0047] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the first key 21 and the second key 22 can be set to be formed as a cylinder. Through the above arrangement, during the movement of the movable scroll component, it can be ensured that the cross ring 100 is always in line contact with the movable scroll component and the fixed component, which is beneficial to improving the guiding effect of the limit key 2 and reducing the difficulty of processing the limit key 2.

[0048] In some embodiments of the present invention, Figure 5 As shown, the cross slip ring 100 of the compressor of the embodiment of the utility model further includes a wear-resistant sleeve 3, which can be made of wear-resistant materials such as molybdenum disulfide and ceramics. The wear-resistant sleeve 3 is cylindrical and is used to be rotatably sleeved on the outside of at least one pair of limit keys 2. For example, the wear-resistant sleeve 3 can be set to two, and the two wear-resistant sleeves 3 are respectively sleeved on the outside of the two first keys 21; or, the wear-resistant sleeve 3 can be set to two, and the two wear-resistant sleeves 3 are respectively sleeved on the outside of the two second keys 22; or, the wear-resistant sleeve 3 can be set to two, and the two wear-resistant sleeves 3 are respectively sleeved on the outside of the two first keys 21, and the other two wear-resistant sleeves 3 are respectively sleeved on the outside of the two second keys 22, and the present application does not limit this.

[0049] Through the above-mentioned arrangement, the sliding friction between the limit key 2 and the fixed component and the movable scroll component can be further converted into rotational friction, thereby reducing the friction resistance and the power loss. The cross slip ring 100 can be quickly repaired by replacing the wear-resistant sleeve 3 subsequently, thereby increasing the service life of the cross slip ring 100.

[0050] It should be noted that, in the present application, the surface of the limit key 2 can also be plated to improve the wear resistance of the limit key 2. Of course, other solutions that can improve the wear resistance of the limit key 2 are within the protection scope of the present application.

[0051] In some embodiments of the present invention, the axial length of the wear-resistant sleeve 3 is w1, and the axial length of the limit key 2 is w2, which satisfies: 0.5≤w1 / w2≤07.

[0052] For example, the axial length of the wear-resistant sleeve 3 can be set to w1, and the axial length of the limit key 2 can be set to w2, satisfying: 0.5≤w1 / w2≤07. In other words, the ratio of the axial length w1 of the wear-resistant sleeve 3 to the axial length w2 of the limit key 2 can be set to be greater than or equal to 0.5, and less than or equal to 0.7, such as 0.55, 0.6, 0.65, etc. Through the above setting, while ensuring that the wear-resistant sleeve 3 can effectively shield the outer peripheral wall of the limit key 2, the size of the wear-resistant sleeve 3 can be reduced, which is conducive to reducing the friction area and processing cost.

[0053] In some embodiments of the present invention, Figure 5 As shown, the wear-resistant sleeve 3 can be arranged in the middle of the limit key 2 along the axial direction. Preferably, the distances between the two ends of the wear-resistant sleeve 3 and the corresponding ends of the limit key 2 can be arranged to be equal. Through the above arrangement, the guiding effect of the wear-resistant sleeve 3 can be ensured, and the installation stability of the limit key 2 can be improved, thereby improving the reliability of the cross slip ring 100.

[0054] In some embodiments of the present invention, the first key 21 and the second key 22 both include a main body 23 and a protrusion 24 . The main body 23 is polygonal in structure. The protrusion 24 is disposed on the outer peripheral wall of the main body 23 and has an arc surface.

[0055] For example, refer to Figure 6 As shown, the first key 21 and the second key 22 both include a main body 23 and a protruding portion 24, one end of the main body 23 is connected to the ring body 1 and the other end is protruding in a direction away from the ring body 1, the main body 23 is formed into a polygon, such as a quadrilateral, pentagon, hexagon, octagon, etc., the protruding portion 24 is arranged on the side of the outer peripheral wall of the main body 23 opposite to the first guide groove 301 (or the second guide groove 201), and the side of the protruding portion 24 away from the main body 23 is provided with an arc surface. It should be noted that the protruding portion 24 can be made of wear-resistant material.

[0056] Through the above arrangement, the overall size of the limit key 2 can be reduced, which is conducive to the lightweight design of the cross slip ring 100. When the protrusion 24 is made of wear-resistant material, the overall wear resistance of the limit key 2 can be improved, thereby increasing the service life of the cross slip ring 100.

[0057] In some embodiments of the utility model, the protrusion 24 and the main body 23 can be integrally formed to reduce the difficulty of processing the limit key 2; or, the protrusion 24 and the main body 23 can be detachably connected so that the protrusion 24 can be replaced, which is beneficial for subsequent maintenance.

[0058] In some embodiments of the present invention, the main body 23 may be configured as a polygonal structure having opposite side walls such as a quadrilateral, hexagon, or octagon, and each side wall of at least one pair of opposite side walls of the main body 23 may be provided with a protrusion 24 .

[0059] Through the above arrangement, the opposite sides of the main body 23 can be guided and matched with the movable scroll component (or fixed component) through the protrusion 24, which is beneficial to improving the movement stability of the Cross ring 100, and is beneficial to reducing the friction resistance of the movable scroll component and reducing power loss.

[0060] In some embodiments of the utility model, the protrusion 24 can be arranged around the circumference of the main body 23, and the outer wall surface of the protrusion 24 is formed into an arc surface. Through the above arrangement, while reducing the overall weight of the cross ring 100, the matching stability between the limit key 2 and the first guide groove 301 (or the second guide groove 201) can be ensured, thereby improving the reliability of the cross ring 100.

[0061] In some embodiments of the present invention, Figure 2As shown, the protruding directions of the first key 21 and the second key 22 can be set opposite. For example, the first key 21 can be set to protrude radially outward, and the second key can be set to protrude radially inward. Through the above arrangement, it is easy to distinguish the first key 21 and the second key 22, which helps to reduce the difficulty of installing the cross slip ring 100.

[0062] In some embodiments of the present invention, the first key 21 and the second key 22 are respectively located on opposite sides of the ring body 1 along the axial direction. Figure 2 As shown, a first key 21 can be provided to protrude toward one end along the axial direction of the ring body 1, and a second key 22 can be provided to protrude toward the other end along the axial direction of the ring body 1, so that the first key 21 and the second key 22 can be respectively located on opposite sides of the ring body 1 along the axial direction. The cross ring 100 is used to be installed between the fixed component and the movable scroll component, so that the first key 21 can be limitedly matched with the fixed component along the axial direction of the ring body 1, and the second key 22 can be limitedly matched with the movable scroll component along the axial direction of the ring body 1. It should be noted that the movable scroll component is a movable scroll 200, and the fixed component is a bracket 300, and the cross ring 100 is installed between the movable scroll 200 and the bracket 300.

[0063] The above arrangement helps to reduce the difficulty of matching the Cross ring 100 with the fixed component and the movable scroll component, thereby improving the practicality of the Cross ring 100.

[0064] Of course, this application is not limited to this. Figure 7 As shown, the first key 21 and the second key 22 can be arranged on the same side of the ring body 1 along the axial direction, the cross ring 100 is arranged on the same side of the movable scroll component and the fixed component, the first key 21 can be limitedly matched with the fixed component along the axial direction of the ring body 1, and the second key 22 can be limitedly matched with the movable scroll component along the axial direction of the ring body 1, so as to limit the movable scroll component from rotating around its own axial direction relative to the fixed component. It should be noted that the movable scroll component is the movable scroll 200, and the fixed component is the fixed scroll, and the cross ring 100 is installed on the side of the movable scroll 200 away from the fixed scroll.

[0065] In some embodiments of the present invention, Figure 3 As shown, in the axial projection of the ring body 1, the maximum distance between the outer wall of the orthographic projection of the first key 21 and the center of the orthographic projection of the ring body 1 can be set to the first distance, and the maximum distance between the outer wall of the orthographic projection of the second key 22 and the center of the orthographic projection of the ring body 1 can be set to the second distance, and the first distance and the second distance are set equal.

[0066] For example, a first key 21 may be provided to protrude toward one end along the axial direction of the ring body 1, and a second key 22 may be provided to protrude toward the other end along the axial direction of the ring body 1, so that the first key 21 and the second key 22 may be respectively located on opposite sides of the ring body 1 along the axial direction, so that the axial projections of the first key 21 and the second key 22 coincide with the projection of the ring body 1, thereby making the first distance and the second distance equal.

[0067] Through the above arrangement, the radial space of the cross ring 100 can be utilized to the maximum extent, which is conducive to reducing the radial size of the cross ring 100, and realizing the lightweight design of the cross ring 100. In addition, the first key 21 and the second key 22 can be set to the same structure to reduce the difficulty of positioning and installing the cross ring 100, thereby improving the practicality of the cross ring 100.
