Abstract
Description
Technical Field
[0001] This application relates to the field of compressor technology, specifically to a vane and compressor for use in a compressor. Background Technology
[0002] Currently, in roller compressors, the cylinder end face typically mates with a flange to form a sealed working chamber. The crankshaft drives the rollers to roll within the working chamber, and a vane is slidably positioned within a groove communicating with the working chamber. Through the dynamic contact between the vane head and the outer wall of the roller, the working chamber is divided into an intake chamber and an exhaust chamber. During compressor operation, the rollers rotate, meaning there is relative movement between the outer wall of the roller and the vane head. This generates friction, resulting in wear and friction noise.
[0003] The related technology discloses a vane of a compressor. The vane includes a vane body and a head. The head is usually abutted against a roller so that the vane body moves back and forth with the roller in the vane groove. The cross-sectional area of the vane body is smaller than the maximum cross-sectional area of the head, so that the pressure borne by the vane during the reciprocating motion with the roller is relatively small, thereby reducing the wear between the head and the roller.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] In related technologies, although the pressure on the slider can be reduced by making the cross-sectional area of the slider body smaller than the maximum cross-sectional area of the head, the head still needs to withstand the force from the roller. The slider is prone to deformation under long-term stress, necessitating improvements in its impact resistance.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0015] Optionally, the support parts of adjacent hollow structures are connected in sequence.
[0016] Optionally, the hollow structure extends along the height direction of the slide body.
[0017] Optionally, the slider head protrudes in an arc shape in the direction away from the slider body; when there are multiple hollow structures, the dimensions of the multiple hollow structures in the length direction of the slider body gradually decrease from the middle to both ends in the width direction of the slider body.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0043] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides a vane 30 for a compressor 10. The compressor 10 includes a cylinder 20 and a roller 40. The cylinder 20 is provided with a vane groove 22 and a working chamber 23. The vane 30 is adapted to be movably disposed in the vane groove 22, and the roller 40 is disposed in the working chamber 23. The vane 30 includes a vane body 35 and a vane head 36.
[0044] The slide head 36 is located at one end of the slide body 35 facing the roller 40, and the slide head 36 is adapted to abut against the roller 40; wherein, a reinforcing member 37 is provided between the slide head 36 and the slide body 35, the reinforcing member 37 includes a hollow structure 370, and the two ends of the hollow structure 370 abut against the slide head 36 and the slide body 35 respectively.
[0045] The vane 30 for compressor 10 provided in this embodiment has a reinforcing member 37 between the vane head 36 and the vane body 35. The hollow structure 370 of the reinforcing member 37 forms a buffer space, and its two ends abut against the vane head 36 and the vane body 35 respectively, effectively dispersing the pressure on the vane head 36. When the vane head 36 contacts the roller 40 and is subjected to force, the hollow structure 370 can evenly distribute the stress, preventing excessive stress concentration at the contact area between the vane head 36 and the roller 40. This improves the impact resistance of the vane 30 and avoids or reduces problems such as deformation and wear of the vane head 36 caused by excessive local stress.
[0046] Optionally, the hollow structure includes a protrusion 371 that protrudes in an arc shape toward the slider head 36 and abuts against the slider head 36.
[0047] The protrusion 371 of the hollow structure 370 protrudes in an arc shape toward the slider head 36 and abuts against the slider head 36, which can effectively enhance the structural strength of the slider head 36. This can effectively improve the impact resistance of the slider head 36 and maintain the tight fit between the slider 30 and the roller 40.
[0048] Furthermore, during the operation of the compressor 10, radial vibration is generated when the roller 40 drives the vane 30 to move. When the vane head 36 is under force, the arc-shaped protrusion 371 can absorb and decompose the radial vibration. When vibration occurs, the protrusion 371 can produce slight elastic deformation, absorbing vibration energy and reducing the impact of vibration on the vane head 36 and the main body. This can reduce the collision and wear between the vane 30 and the roller 40, and between the vane 30 and the vane groove 22 caused by vibration, improve the smoothness of compressor 10 operation, and reduce noise generation.
[0049] Optionally, combined Figure 2 and Figure 3 As shown, the hollow structure 370 also includes a transition portion 372, which is provided on the end side of the protrusion 371 facing the slide body portion 35. The transition portion 372 is connected to the protrusion 371, and the transition portion 372 is inclined and contracted inward along the direction of the slide head 36 toward the slide body portion 35.
[0050] The transition portion 372 is located on the end side of the protrusion 371 facing the slide head 35, that is, the transition portion 372 is located on the end side of the protrusion 371 away from the slide head 36. The transition portion 372 is connected to the protrusion 371, which protrudes in an arc shape towards the slide head 36, and the transition portion 372 slopes inward and contracts in the direction from the slide head 36 towards the slide head 35, so that the hollow structure 370 is formed with a structure that gradually contracts inward at both ends of the arc-shaped protrusion. When the roller 40 applies pressure to the slide head 36, the sloped contraction structure of the transition portion 372 can play a buffering role. When the pressure is transmitted from the slide head 36 through the protrusion 371 to the transition portion 372, it can be gradually dispersed and the impact reduced. This transition design can avoid stress concentration caused by sudden changes in force, alleviate the stress on the slide head 36, improve the stability of the contact between the slide head 36 and the roller 40, and enhance the overall strength of the slide 30 under stress.
[0051] Optionally, combined Figure 4As shown, the protrusion 371 includes a first end 3711 and a second end 3712 located at both ends of the arc-shaped protrusion. The transition portion 372 includes a first connecting rib 3721 and a second connecting rib 3722. One end of the first connecting rib 3721 is connected to the first end 3711, and the first connecting rib 3721 is inclined toward the second connecting rib 3722. One end of the second connecting rib 3722 is connected to the second end 3712, and the second connecting rib 3722 is inclined toward the first connecting rib 3721.
[0052] The transition portion 372 is connected to the first end 3711 and the second end 3712 of the protrusion 371 via the first connecting rib 3721 and the second connecting rib 3722, respectively, forming a continuous support structure that allows the slider head 36 to better distribute stress when subjected to force. The first connecting rib 3721 and the second connecting rib 3722 are inclined inwards towards each other, causing the first connecting rib 3721 and the second connecting rib 3722 to gradually contract along the direction from the slider head 36 towards the slider body 35, thereby forming a buffer structure. When vibration occurs, the inclined first connecting rib 3721 and the second connecting rib 3722 can effectively absorb and disperse vibration energy, reducing the impact of vibration on the slider head 36 and the body.
[0053] Optionally, combined Figure 4 As shown, the hollow structure 370 also includes a support portion 373, which is connected to the transition portion 372. The support portion 373 extends along the width direction of the slide body portion 35, and a buffer space 374 is formed between the protrusion 371, the transition portion 372 and the support portion 373 of the hollow structure 370.
[0054] Combination Figure 1 As shown, the x-axis indicates the width of the slider body, the y-axis indicates the length of the slider body, and the z-axis indicates the height of the slider body.
[0055] The hollow structure 370 has a protrusion 371, a transition portion 372, and a support portion 373 arranged sequentially along the length of the slider body 35. The protrusion 371 protrudes in an arc shape toward the slider head 36. The transition portion 372 is connected to the protrusion 371 and slopes inward toward the slider body 35 along the slider head 36. The support portion 373 is connected to the transition portion 372 and extends along the width of the slider body 35. This makes the hollow structure 370 form an inverted Ω shape or a similar inverted Ω shape, thereby improving the impact resistance of the hollow structure 370 and enhancing the overall structural strength and stability of the slider 30.
[0056] The support portion 373 connects to the transition portion 372 and extends along the width direction of the slide body portion 35. The protrusion 371, transition portion 372, and support portion 373 form a buffer space 374. When subjected to pressure from the roller 40, the buffer space 374 effectively disperses the impact force and absorbs vibration energy. Simultaneously, the connection between the support portion 373 and the transition portion 372, extending along the width direction of the slide body portion 35, enhances the overall rigidity and stability of the hollow structure 370. Under pressure from the roller 40, the support portion 373 provides strong support, enhancing the reinforcement 37's resistance to deformation.
[0057] Optionally, the dimension of the protrusion 371 in the length direction of the slide body 35 is a first dimension, and the total dimension of the protrusion 371 and the transition portion 372 in the length direction of the slide body 35 is a second dimension, wherein the ratio of the first dimension to the second dimension is greater than or equal to 0.3 and less than or equal to 0.5.
[0058] The protrusion 371, transition portion 372, and support portion 373 of the hollow structure 370 are sequentially arranged along the length direction of the slider body portion 35. The dimension of the protrusion 371 in the length direction of the slider body portion 35 is a first dimension, and the total dimension of the protrusion 371 and transition portion 372 in the length direction of the slider body portion 35 is a second dimension. The ratio of the first dimension to the second dimension is the arc-height ratio of the hollow structure 370. The dimension of the protrusion 371 in the length direction of the slider body portion 35 is as follows: Figure 3 As shown in H1, the total dimension of the protrusion 371 and the transition portion 372 in the length direction of the slider body portion 35 is as follows: Figure 3 As shown in H.
[0059] When the ratio of the first dimension to the second dimension is greater than or equal to 0.3, the arc-shaped protrusion structure of the protrusion 371 has sufficient length to contact the slider head 36, thereby enhancing the structural strength of the slider head 36 and providing effective support and stress dispersion.
[0060] When the ratio of the first dimension to the second dimension is less than or equal to 0.5, the protrusion 371 can be prevented from being too long, allowing the transition portion 372 to occupy an appropriate size proportion in the reinforcement 37. This enables the transition portion 372 to effectively buffer and disperse the force transmitted from the protrusion 371, thereby improving the impact resistance of the entire reinforcement 37.
[0061] This embodiment of the invention comprehensively considers the contact support requirements between the protrusion 371 and the slider head 36, as well as the rationality and mechanical performance of the overall structure of the reinforcing member 37, and limits the ratio of the first dimension to the second dimension to a range of 0.3 to 0.5. This range ensures that the protrusion 371 has sufficient length to contact the slider head 36 and provide effective support and stress dispersion, while also allowing the transition portion 372 to play an effective buffering role, thereby optimizing the stress performance of the slider 30.
[0062] It is understandable that the ratio of the first dimension to the second dimension can be 0.3, 0.35, 0.4, 0.45, 0.5, etc.
[0063] Optionally, the dimension of the support portion 373 in the width direction of the slide body portion 35 is a third dimension, and the ratio of the third dimension to the second dimension is greater than or equal to 1 and less than or equal to 1.5.
[0064] The dimension of the support portion 373 in the width direction of the slide body portion 35 is as follows: Figure 3 As shown in Figure B. The third dimension is 1 to 1.5 times the second dimension. When the second dimension increases, the third dimension must also increase accordingly. When the second dimension decreases, the third dimension must also decrease accordingly.
[0065] When the ratio of the third dimension to the second dimension is greater than or equal to 1, the dimension of the support portion 373 in the width direction of the slide body portion 35 is greater than the total dimension of the protrusion 371 and the transition portion 372 in the length direction of the slide body portion 35. This allows the support portion 373 to provide a larger support area for the protrusion 371 and the transition portion 372, thereby enhancing the stability of the reinforcing member 37.
[0066] When the ratio of the third dimension to the second dimension is less than or equal to 1.5, the protrusion 371 and the transition 372 can achieve a buffering effect, providing a solid support structure and an effective buffer space 374 for the slide head 36, thereby effectively resisting the pressure from the roller 40, while also preventing the support 373 from occupying too much width space.
[0067] The embodiments disclosed herein limit the ratio of the third dimension to the second dimension to a range of 1 to 1.5, which enables the reinforcement 37 to achieve a balance between providing sufficient support strength and occupying space in the width direction.
[0068] It is understandable that the ratio of the third dimension to the second dimension can be 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, and so on.
[0069] Optionally, combined Figure 2 As shown, the reinforcing member 37 includes a plurality of hollow structures 370, which are arranged along the width direction of the slide body 35.
[0070] Multiple hollow structures 370 of the reinforcing member 37 are arranged along the width direction of the slide body 35, which can buffer and support different positions of the slide head 36. When the roller 40 applies pressure to the slide head 36, the multiple hollow structures 370 can more comprehensively disperse the stress, making the force on the slide head 36 more balanced and effectively reducing the possibility of local stress concentration. This can enhance the overall structural strength and deformation resistance of the slide head 36, and effectively improve the structural strength of the slide 30.
[0071] Optionally, combined Figure 2 As shown, multiple hollow structures 370 are arranged sequentially along the width direction of the slide body 35.
[0072] When multiple hollow structures 370 are arranged sequentially, they form a continuous support structure, which reinforces the slider head 36 as a whole. This effectively disperses stress and improves the structural strength of the slider 30.
[0073] Optionally, a plurality of hollow structures 370 are arranged at intervals along the width direction of the slide body 35.
[0074] When multiple hollow structures 370 are arranged at intervals, they can form multiple distributed support points at the slider head 36. These support points cooperate with each other to evenly distribute stress.
[0075] Optionally, combined Figure 2 As shown, the support portions 373 of adjacent hollow structures 370 are connected in sequence.
[0076] Multiple hollow structures 370 are arranged along the width direction of the slide body 35, and the support portions 373 of adjacent hollow structures 370 are connected in sequence to form a continuous integral structure. The multiple hollow structures 370 support each other and can collectively withstand the pressure applied by the roller 40. When the slide head 36 is subjected to pressure, the pressure is transmitted and dispersed between the hollow structures 370 through the sequentially connected support portions 373, thereby effectively improving the overall load-bearing capacity of the slide 30 and enhancing its resistance to deformation. The support portion 373 can be a support plate, and the support plates of adjacent hollow structures 370 are connected in sequence to form a complete support panel.
[0077] Optionally, combined Figure 1 and Figure 4 As shown, the hollow structure 370 extends along the height direction of the slide body 35.
[0078] The height direction of the slider body 35 is the same as the height direction of the slider head 36. The hollow structure 370 extends along the height direction of the slider body 35, enabling it to provide comprehensive support and reinforcement for the slider head 36 in the height direction of the slider body 35. When the slider head 36 contacts the roller 40 and is subjected to force, the hollow structure 370 can effectively disperse and transmit the force along the entire height direction of the slider body 35, preventing local deformation of the slider head 36 due to excessive force and improving the overall structural strength of the slider 30.
[0079] Optionally, combined Figure 1 As shown, the height of the slider head 36 is the same as the height of the slider body 35 and the height of the hollow structure 370.
[0080] The height of the slider head 36 is consistent with the height of the slider body 35 and the height of the hollow structure 370. This can maintain the structural continuity and integrity of the slider 30 in the height direction, and effectively enhance the stability and deformation resistance of the slider 30.
[0081] Optionally, combined Figure 2 As shown, the slider head 36 protrudes in an arc shape in the direction away from the slider body 35; when there are multiple hollow structures 370, the dimensions of the multiple hollow structures 370 in the length direction of the slider body 35 gradually decrease from the middle to both ends in the width direction of the slider body 35.
[0082] During actual operation of the compressor 10, the vane head 36 is in contact with the outer wall surface 41 of the roller 40, and the roller 40 rotates, meaning there is relative movement between the outer wall surface 41 of the roller 40 and the vane head 36, generating friction. The arc-shaped protrusion of the vane head 36 matches the outer arc surface of the roller 40, enabling more uniform force transmission and reducing wear and friction noise when the vane head 36 contacts the roller 40. Furthermore, the arc-shaped structure can undergo a certain degree of elastic deformation under stress, providing cushioning and shock absorption, effectively reducing the impact and vibration experienced by the vane head 36.
[0083] The middle portion of the slider head 36 typically experiences relatively higher stress, while the ends experience relatively lower stress. Multiple hollow structures 370 are designed to match the arcuate extension shape of the slider head 36 along the length of the slider body 35, gradually decreasing in size from the middle to both ends along the width of the slider body 30. This provides stronger support and stress dispersion for the middle portion of the slider head 36. The slider head 36 is designed with a gradually changing fan-shaped arc edge, forming a symmetrical structure that allows it to maintain better balance and stability under stress.
[0084] Optionally, combined Figure 5 and Figure 6As shown, the vane groove 22 includes a connected sliding cavity 226 and a reset cavity 227. The cross-sectional area of the reset cavity 227 is larger than that of the sliding cavity 226. The vane body 35 moves in the sliding cavity 226. The vane 30 for the compressor 10 also includes a vane tail 34. The vane tail 34 is connected to one end of the vane body 35 away from the vane head 36. The vane tail 34 is located in the reset cavity 227. The cross-sectional area of the vane tail 34 is larger than that of the sliding cavity 226. When the vane tail 34 moves toward the working cavity 23, it can abut against and limit the movement of the front cavity wall 228 of the reset cavity 227.
[0085] When the slider 30 moves within the slider groove 22, the slider tail 34 can move smoothly within the reset cavity 227 without being obstructed due to insufficient space. The cross-sectional area of the slider tail 34 is larger than that of the sliding cavity 226. When the slider 30 moves from the slider groove 22 toward the working cavity 23 to its maximum displacement, the slider tail 34 moves toward the working cavity 23 to its limit position, where it abuts against the front cavity wall 228 of the reset cavity 227 for limitation. This effectively prevents the slider 30 from extending excessively beyond the slider groove 22, thereby avoiding excessive compression or collision between the slider head 36 and the roller 40, and preventing damage to the slider 30 and the roller 40.
[0086] Optionally, combined Figure 5 As shown, the slider tail 34 protrudes to both sides of the slider body 35 along the width direction of the slider body 35, and the cross-sectional area of the slider tail 34 is larger than the cross-sectional area of the slider body 35, and the cross-sectional area of the reset cavity 227 is larger than the cross-sectional area of the sliding cavity 226.
