Description

Technical Field

[0001] This application relates to the field of scroll compressor technology, and in particular to a frame for a scroll compressor and a scroll compressor. Background Technology

[0002] The frame of a scroll compressor serves as a support component for the moving scroll disc, and its structural characteristics directly affect the performance of the scroll compressor.

[0003] During the operation of a scroll compressor, there is continuous relative motion between the moving scroll plate and the support surface of the frame. In existing designs, the support surface of the frame is generally a smooth plane, which makes it difficult for lubricating oil to effectively adhere to the support surface. When the moving scroll plate is operating at high speed, insufficient lubrication will cause significant wear between the mating parts of the support surface and the moving scroll plate, thus negatively impacting the lifespan of the scroll compressor. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a frame for a scroll compressor and a scroll compressor, so as to solve the problem that lubricating oil is difficult to adhere to the support surface of the frame.

[0005] According to a first aspect of the present invention, a frame for a scroll compressor is provided, wherein the frame for the scroll compressor includes a frame body; an annular support surface formed on the frame body, wherein the bottom surface of the moving scroll disk of the scroll compressor contacts the annular support surface; a keyway formed on the frame body, the keyway being used to engage with an anti-rotation slip ring of the scroll compressor; and an oil groove provided on the annular support surface, wherein a spacer is provided between the oil groove and the keyway.

[0006] Preferably, the oil trough is annular in shape and has a V-shaped cross-section.

[0007] Preferably, the depth of the oil tank is 1 mm to 2 mm.

[0008] Preferably, the width of the oil trough is 1 mm to 2 mm.

[0009] Preferably, an anti-rotation slip ring groove is formed on the frame body, and the anti-rotation slip ring groove is disposed on the inner side of the annular support surface.

[0010] Preferably, a protrusion is formed on the anti-rotation slip ring groove, the keyway is formed in the protrusion, and the keyway portion is formed on the annular support surface.

[0011] Preferably, the keyway is formed in the shape of a strip, the keyway is arranged radially along the frame body, the end of the keyway near the oil groove is formed in the shape of an arc, and the spacer is formed between the end of the keyway and the oil groove.

[0012] Preferably, the top surface of the protrusion is formed as a support plane, and the width of the support plane gradually increases in the direction away from the axis of the frame body.

[0013] Preferably, the end of the support plane away from the axis of the frame body is the first end, and the end of the support plane close to the axis of the frame body is the second end, and the ratio of the width of the first end to the width of the second end is 7 / 4.

[0014] According to a second aspect of the present invention, a scroll compressor is provided, wherein the scroll compressor includes a frame for a scroll compressor as described above.

[0015] The present invention relates to a scroll compressor frame and a scroll compressor, wherein an annular support surface is formed on the frame body. The bottom surface of the moving scroll disk of the scroll compressor contacts the annular support surface. A keyway is formed in the frame body, which is used to engage with the anti-rotation slip ring of the scroll compressor. An oil groove is formed on the annular support surface, and a gap is provided between the oil groove and the keyway. This arrangement allows lubricating oil to flow into the oil groove for storage during the operation of the scroll compressor, thereby lubricating the annular support surface and preventing wear between the frame and the moving scroll disk. The gap prevents lubricating oil in the oil groove from leaking from the keyway, thus ensuring that the lubricating oil in the oil groove remains sufficient, effectively solving the problem of lubricating oil being difficult to adhere to the support surface of the frame.

[0031] like Figures 1 to 3 As shown, according to the first aspect of the present invention, a frame for a scroll compressor is provided, the frame for the scroll compressor including a frame body 1, an annular support surface 2, a keyway 3 and an oil groove 4.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the aforementioned components of the frame used for the scroll compressor and the connection relationship of the aforementioned components are described in detail.

[0033] like Figures 1 to 3 As shown, in this embodiment, the frame body 1 can be installed on the inner wall of the scroll compressor casing. An annular support surface 2 can be formed on the frame body 1 to support the moving scroll disk 8. During operation, the bottom surface of the moving scroll disk 8 contacts the annular support surface 2. An oil groove 4 can be formed on the annular support surface 2. This arrangement allows lubricating oil to flow into the oil groove 4 for storage during the operation of the scroll compressor, thus lubricating the annular support surface 2 and preventing wear between the frame and the moving scroll disk 8. A keyway 3 is also formed on the frame body 1, which is used to engage with the anti-rotation slip ring of the scroll compressor. A gap is provided between the oil groove 4 and the keyway 3 to prevent lubricating oil in the oil groove 4 from leaking from the keyway 3, thereby ensuring that the lubricating oil in the oil groove 4 remains sufficient.

[0034] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the oil groove 4 can be annular in shape. The oil groove 4 can be located at the center of the annular support surface 2 in the radial direction. Preferably, the cross-section of the oil groove 4 is V-shaped. This design reduces the cutting force required to machine the oil groove 4, thereby increasing the tool life. Furthermore, when the cross-section of the oil groove 4 is V-shaped, the structure of the oil groove 4 is more stable, and lubricating oil flows easily into the oil groove 4.

[0035] However, this is not the only option. The provision of an annular oil groove 4 on the annular support surface 2 is merely a preferred embodiment. As long as the function of storing oil in the oil groove 4 can be achieved, the oil groove 4 can also be configured in other ways, such as having two semi-circular oil grooves 4 on the annular support surface 2.

[0036] Furthermore, preferably, such as Figures 1 to 3 As shown, in this embodiment, the depth of the oil groove 4 can be 1mm to 2mm. The width of the oil groove 4 can be 1mm to 2mm. This configuration ensures that the oil groove 4 can store a sufficient amount of lubricating oil, while also facilitating machining by the cutting tool.

[0037] Preferred, such as Figure 1 and Figure 2As shown in the embodiment, an anti-rotation slip ring groove 5 can be formed on the frame body 1. Specifically, the anti-rotation slip ring groove 5 can be an annular groove, which is used to install the anti-rotation slip ring of the scroll compressor. The anti-rotation slip ring groove 5 can be located inside the annular support surface 2, and the outer diameter of the anti-rotation slip ring groove 5 can be equal to the inner diameter of the annular support surface 2. The bottom surface of the anti-rotation slip ring groove 5 is lower than the annular support surface 2 to accommodate the anti-rotation slip ring.

[0038] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, a protrusion 6 can be formed on the anti-rotation slip ring groove 5, and the protrusion 6 can protrude from the bottom surface of the groove 5. There can be multiple protrusions 6. Preferably, there can be two protrusions 6. The two protrusions 6 can be respectively disposed on both sides of the anti-rotation slip ring groove 5. The keyway 3 can be formed within the protrusion 6, and the keyway 3 can also be partially formed on the annular support surface 2. A key that can cooperate with the keyway 3 can be formed at the bottom of the anti-rotation slip ring, so that the keyway 3 can guide the movement of the anti-rotation slip ring.

[0039] Furthermore, preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the keyway 3 can be formed in the shape of a strip. The keyway 3 can be arranged radially along the frame body 1 (i.e., the length direction of the keyway 3 is radial to the frame body 1). The end of the keyway 3 near the oil groove 4 can be formed in the shape of an arc, and the arc-shaped part of the keyway 3 can be formed at the annular support surface 2, so that the moving scroll plate 8 can be supported by the annular support surface 2 throughout its movement. The spacer is formed between the end of the keyway 3 and the oil groove 4, so that the oil groove 4 is not connected to the keyway 3.

[0040] In addition, preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the top surface of the protrusion 6 can be formed as a support plane 60. The support plane 60 can be horizontally arranged to support the anti-rotation slip ring. The width of the support plane 60 can gradually increase along the direction away from the axis of the frame body 1 to improve the stability of the moving scroll plate 8 during movement.

[0041] Furthermore, preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the end of the support plane 60 away from the axis of the frame body 1 can be a first end, and the end of the support plane 60 close to the axis of the frame body 1 can be a second end. The width of the first end can be increased compared to the second end. Specifically, the ratio of the width of the first end to the width of the second end can be 7 / 4. For example, the width 71 of the first end can be 28 mm, and the width 72 of the second end can be 16 mm. In a scroll compressor, since the moving scroll disk 8 is driven by the crankshaft 9, it also slides horizontally while rotating. Therefore, increasing the width 71 of the first end of the support plane 60 can improve the stability of the moving scroll disk 8 when it reaches its limit position, preventing the moving scroll disk 8 from overturning or deflecting improperly, thereby ensuring the stability of the scroll compressor operation.

[0042] In addition, such as Figure 3 As shown, according to a second aspect of the present invention, a scroll compressor is provided, the scroll compressor including the frame for a scroll compressor as described above.

[0043] During use, the oil groove 4 stores lubricating oil to reduce friction between the moving scroll plate 8 and the annular support surface 2, thereby extending the service life of the scroll compressor. A gap is provided between the oil groove 4 and the keyway 3 to prevent lubricating oil in the oil groove 4 from leaking into the anti-rotation slip ring groove 5, thus ensuring sufficient lubricating oil in the oil groove 4. Furthermore, the width 71 of the first end of the support plane 60 is widened, making the moving scroll plate 8 more stable when sliding to its limit position, thereby ensuring the stability of the scroll compressor's operation.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
