Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a roller vane assembly and a compressor. Background Technology

[0002] In various transmission devices such as oscillating rotor compressors, the hinge structure between the vane and the roller is a core component for power transmission and ensuring normal equipment operation. Its structural rationality directly determines the equipment's operational stability and service life. In traditional hinge structure designs, the vane head is embedded in the roller hinge groove, and the two mainly cooperate through sliding or oscillation. When the compressor operates under high-pressure conditions, the vane is subjected to high-pressure gas, generating significant compressive force towards the roller. This leads to excessively high contact stress in the contact area between the vane head and the roller groove. Under prolonged conditions like this, the contact surfaces of the vane and roller are prone to wear, fatigue deformation, and in severe cases, fracture. This not only shortens the equipment's service life but may also cause equipment downtime, leaks, and other safety hazards, affecting overall operational reliability.

[0003] Currently, existing technologies for hinged structures between slides and rollers mostly adopt a rigid design approach, without setting up effective buffering and stress relief mechanisms. This makes it difficult to effectively alleviate the impact force generated in high-pressure areas, and thus it is difficult to fundamentally solve the problems of excessive contact stress and wear between the two.

[0004] To address some of the aforementioned deficiencies, several improvement schemes have been proposed in related fields. Among them, prior art document 1 discloses a pump body assembly. This assembly has annular grooves distributed around the circumference of the roller's outer peripheral wall, and a locking part that can be movably embedded in the annular groove is provided on the end face where the vane contacts the roller. Through the cooperation of the locking part and the annular groove, sliding contact between the vane and the roller is achieved in the circumferential direction, as well as stop contact in the radial direction. While this structure effectively prevents the vane from separating from the roller and increases the compression space volume and compressor discharge capacity without changing the component dimensions, it does not optimize for the contact stress problem under high-pressure conditions and still cannot solve the potential wear risk of the vane and roller.

[0005] Prior art document 2 discloses a roller slide assembly. This assembly achieves a hook-and-engagement connection by having a hook structure in one of the slides and a hook-and-engagement structure in the other, with the two engaging with each other through point contact. Compared to the traditional method where the slide head abuts against the outer circumference of the roller, this structure improves operational following reliability, effectively prevents the two from disengaging, and reduces low-frequency noise and vibration. The point contact design also reduces frictional power consumption, offering certain advantages in energy efficiency. However, this structure also lacks a buffer mechanism, failing to mitigate the impact forces generated in high-pressure areas and still not solving the wear problem caused by excessive contact stress under high-pressure conditions.

[0006] In summary, existing sliding vane and roller hinge structures and related improvement schemes have failed to effectively solve the contact stress and wear problems under high pressure environments. Therefore, there is an urgent need for a hinge structure that can effectively buffer the impact force on the vane head and optimize the contact stress distribution under high pressure conditions, thereby reducing component wear and extending the service life of equipment.

[0025] This invention provides a roller vane assembly and compressor that improves contact stress distribution, reduces wear between the vane and the roller, and increases the service life of parts.

[0026] The following is combined Figures 1 to 24 The technical solution provided by this invention will be described in more detail below.

[0027] This invention provides a roller slide assembly, comprising: Roller 100; The slide 200 is movably connected to one side of the roller 100; The roller 100 is provided with a hinge groove 110, and the slide 200 is provided with a hinge joint 210, the hinge joint 210 being nested within the hinge groove 110; A flexible structure 300 is provided on at least one of the hinge joint portion 210 and the hinge groove 110, and the flexible structure 300 is disposed at the contact position when the hinge joint portion 210 and the hinge groove 110 move relative to each other.

[0028] The roller slide assembly provided by the present invention includes a roller 100 and a slide 200. The slide 200 is movably connected to one side of the roller 100. The roller 100 is provided with a hinge groove 110, and the slide 200 is provided with a hinge joint 210. The hinge joint 210 is nested in the hinge groove 110 and can slide or swing within the hinge groove 110. A flexible structure 300 is provided on at least one of the hinge joint 210 and the hinge groove 110, and the flexible structure 300 is disposed at the contact position when the hinge joint 210 and the hinge groove 110 move relative to each other. The flexible structure 300 can buffer the high-pressure contact position when the hinge joint 210 and the hinge groove 110 move relative to each other, thereby improving the contact stress distribution, reducing wear between the slide 200 and the roller 100, and improving the service life of the parts.

[0029] It is understood that a flexible structure 300 is provided on the hinge portion 210 and / or the hinge groove 110. When the compressor operates, causing the vane 200 to be subjected to high-pressure gas, a huge contact stress will be generated between the hinge portion 210 and the hinge groove 110. At this time, the flexible structure 300 located at the critical contact position can undergo adaptive micro-deformation, thereby effectively buffering the high-pressure impact and avoiding stress concentration caused by rigid contact. The buffering effect not only optimizes the stress distribution on the contact surface, making it more uniform, but also significantly reduces the friction and wear between the vane 200 and the roller 100, effectively suppressing the generation and propagation of fatigue cracks. Therefore, the present invention fundamentally solves the problem of easy wear and breakage of traditional rigid hinge structures, significantly improves the service life of the vane 200 and the roller 100, and thus enhances the operational stability and reliability of the entire oscillating rotor compressor.

[0030] In some embodiments of the present invention, the flexible structure 300 is a flexible groove 310.

[0031] In some embodiments of the present invention described above, the flexible structure 300 is a flexible groove 310. When the compressor is under high pressure, a large contact stress is generated between the hinge joint 210 and the hinge groove 110. At this time, the flexible groove 310 can undergo controllable micro-deformation due to its structural characteristics. This deformation mechanism effectively absorbs the high-pressure impact energy and forms an elastic buffer layer between the hinge joint 210 and the hinge groove 110, avoiding the stress peak caused by direct contact of traditional rigid structures. Through the yielding and rebound of the flexible groove 310, the stress distribution on the contact surface is significantly improved, greatly reducing the friction and wear between the sliding vane 200 and the roller 100, and effectively suppressing the initiation and propagation of fatigue cracks.

[0032] Specifically, when the flexible groove 310 is provided in the hinge groove 110, the flexible groove 310 is provided on the bottom of the hinge groove 110 or on the inner wall of the groove; when the flexible groove 310 is provided in the hinge joint 210, the flexible groove 310 is provided on the top surface of the hinge joint 210.

[0033] In some embodiments of the present invention, the flexible structure 300 is a single-arm cavity structure 320.

[0034] In some of the embodiments of the present invention described above, the flexible structure 300 is a single-arm cavity structure 320, which forms a local cavity at the hinge, so that one side of the contact area has a controllable elastic deformation capability.

[0035] When the compressor is under high pressure, a huge contact stress is generated between the hinge joint 210 and the hinge groove 110. At this time, the single-arm cavity structure 320, with its unique cantilever design, can undergo adaptive elastic deformation in the direction of force, effectively absorb the high pressure impact energy, and form a dynamic buffer layer at the hinge interface, avoiding the stress peak generated by direct contact of traditional rigid structures.

[0036] Meanwhile, the directional deformation characteristics of the single-arm cavity structure 320 can guide stress distribution along a preset path, dispersing the peak stress concentrated at the contact point to a larger area. This stress distribution effect significantly reduces local wear between the vane 200 and the roller 100, effectively suppressing the initiation and propagation of fatigue cracks. Therefore, this technical solution fundamentally solves the industry problem of easy wear and breakage of the hinged parts under high-pressure conditions, significantly improving the service life of the vane 200 and the roller 100, thereby enhancing the operational stability and reliability of the oscillating rotor compressor.

[0037] It is understood that the single-arm cavity structure 320 is formed by opening a cavity at the bottom of the hinge groove 110 on the roller 100, so that a cantilever is formed between the cavity and the hinge part 210. The hinge part 210 contacts the cantilever, so it can play a buffering role under the action of the cavity.

[0038] In some embodiments of the present invention, an elastic material filling layer is provided inside the single-walled cavity structure 320.

[0039] In some embodiments of the present invention described above, an elastic material filling layer is provided within the single-arm cavity structure 320 to enhance buffering and stress regulation capabilities. When the hinge joint 210 and the hinge groove 110 move relative to each other and generate impact, the filling layer and the cavity structure work together. The cavity provides deformation space, while the elastic material absorbs impact energy through its own compression and promotes uniform stress diffusion. This composite buffering mechanism significantly improves fatigue resistance and effectively reduces wear on the slider 200 and roller 100, thereby extending the service life of the component.

[0040] In some embodiments of the present invention, the filler layer is polyurethane, silicone rubber, or a special elastic alloy.

[0041] In some embodiments of the present invention described above, differentiated cushioning performance is achieved by selecting polyurethane, silicone rubber, or special elastic alloys as filler layer materials. Polyurethane provides high wear resistance and compressive strength, making it suitable for high-frequency impact conditions; silicone rubber, with its excellent elasticity and temperature resistance, ensures stable cushioning performance in high-temperature environments; and special elastic alloys combine high strength and elasticity, making them suitable for heavy-duty applications. This material adaptation design significantly optimizes the contact stress distribution, effectively suppresses wear and fatigue, and extends component life.

[0042] Optionally, a filling layer is provided inside the flexible groove 310.

[0043] In some embodiments of the present invention, the flexible structure 300 is a corrugated elastic metal sheet or an elastic washer.

[0044] In some embodiments of the present invention described above, the flexible structure 300 is configured as a corrugated elastic metal sheet or an elastic washer, achieving structured elastic buffering. The corrugated metal sheet utilizes the compression-rebound characteristics of its waveform structure to generate controllable elastic deformation when the hinge is compressed, effectively absorbing impact energy and dispersing contact stress. The elastic washer, through its own compression deformation, forms a flexible buffer layer at the contact interface, avoiding stress concentration caused by rigid contact. Both structural designs significantly improve the stress state at the hinge, reduce frictional wear between the slider 200 and the roller 100, thereby effectively improving the fatigue resistance and operational reliability of the component.

[0045] In some embodiments of the present invention, the length of the flexible groove 310 is 1 / 6 to 5 / 6 of the length of the hinge joint portion 210 and the hinge groove 110; and / or, the width of the flexible groove 310 is 0.1-1.6 mm.

[0046] In some embodiments of the present invention described above, the length of the flexible groove 310 is controlled to be 1 / 6 to 5 / 6 of the length of the hinge pair. This ensures sufficient deformation area to absorb impact energy while avoiding insufficient overall stiffness of the hinge due to excessive groove length. Limiting the width of the flexible groove 310 to the range of 0.1-1.6 mm ensures effective micro-deformation of the flexible structure 300 while preventing excessive gaps from causing loosening or stress concentration. This dimensional coordination design significantly improves the contact stress distribution, effectively suppresses wear and fatigue between the slider 200 and the roller 100, and enhances the operational stability and service life of the component.

[0047] Furthermore, the ratio of the width of the flexible structure 300 to the thickness of the slider 200 is 0.05-0.75.

[0048] In this further improvement, a precise balance between buffering performance and structural strength is achieved by limiting the ratio of the width of the flexible structure 300 to the thickness of the slider 200 within the range of 0.05-0.75. When the ratio is too small, the flexible structure 300 lacks sufficient deformation capacity and cannot effectively absorb high-pressure impacts; when the ratio is too large, it may lead to a decrease in the stiffness of the slider 200 body, affecting transmission stability. By optimizing this ratio, this invention ensures that the flexible structure 300 can generate appropriate elastic deformation under stress, which not only fully buffers impact energy and improves the distribution of contact stress, but also maintains the overall structural strength of the slider 200, significantly reducing the wear and fatigue risk of the hinge joint and effectively extending the service life of the slider 200 and the roller 100.

[0049] It is understood that when the width of the flexible structure 300 corresponds to the flexible groove 310, it refers to the width of the flexible groove 310; similarly, when it corresponds to the single-arm cavity structure 320, it refers to the width of the single-arm cavity structure 320.

[0050] In some embodiments of the present invention, the flexible structure 300 is distributed in a spiral progressive curve, and the progressive curve satisfies r=a+b*θ, where r: polar radius, a: constant, b: pitch, and θ: polar angle.

[0051] In some embodiments of the present invention described above, the flexible structure 300 is configured to have a spiral-shaped progressive curve distribution, satisfying the mathematical relationship r=a+b*θ, thereby achieving continuous and gradient adjustment of stress distribution. When the hinge joint 210 moves relative to the hinge groove 110, the spiral progressive structure causes the stiffness of the contact area to change regularly along the curve direction, and the impact stress is transmitted and attenuated step by step along the spiral path, avoiding stress abrupt changes and concentrations in traditional structures. This geometric design not only effectively buffers high-pressure impacts but also uniformly guides contact stress to a wider area, significantly reducing the risk of local wear and fatigue of the slider 200 and roller 100, thereby greatly improving the operational stability and service life of the component.

[0052] It is understandable that by setting the flexible structure 300 to a spiral progressive curve distribution, the high stress between the hinge joint 210 and the hinge groove 110 is dispersed to the area of ​​the progressive spiral flexible structure 300, thereby effectively reducing local contact stress. This buffering process can be repeated periodically with the movement of the slider 200 to achieve dynamic stress adjustment.

[0053] In some embodiments of the present invention, θ is 145°-270°, a is greater than the hinge inner diameter r1 of the hinge joint portion 210 and the hinge groove 110, and b is 0.3-1.5.

[0054] In some embodiments of the present invention described above, precise control of the buffering performance is achieved by further defining the key parameters of the helical progressive curve. Setting the polar angle θ to 145°-270° ensures that the flexible structure 300 covers the main stress area of ​​the hinge, allowing the impact stress to be fully buffered and attenuated within the key angle range. The constant a is greater than the hinge inner diameter r1, ensuring that the helical curve starts outside the hinge mating area, avoiding interference with normal movement. The pitch b is limited to 0.3-1.5, allowing stress to be progressively transmitted along the helical path with a suitable gradient, preventing stress abrupt changes, maintaining structural stiffness, significantly improving contact stress distribution, effectively suppressing local wear and fatigue of the slider 200 and roller 100, and improving the operational stability and service life of the component.

[0055] Furthermore, the included angle c of the flexible structure 300 is in the range of θ (145-270°), preferably 40-145°, as shown in the bonding diagram. Figure 23 As shown.

[0056] The present invention also provides a compressor including the roller vane assembly described above.

[0057] The compressor provided by this invention adopts a roller vane assembly with an integrated flexible structure 300. Therefore, under high pressure conditions, it can effectively buffer the impact load between the head of the vane 200 and the hinge groove 110 of the roller 100, significantly improve the contact stress distribution, reduce the wear and fatigue risk of the vane 200 and the roller 100, improve the operational reliability of the hinge part, improve the overall efficiency of the compressor, and significantly enhance the service life and operational stability of the equipment.

[0059] Specifically, the flexible structure 300 is a flexible groove 310, the length of which accounts for 1 / 6 to 5 / 6 of the length of the hinge joint 210 and the hinge groove 110; the width of the flexible groove 310 is 0.1-1.6 mm.

[0060] More specifically, the flexible groove 310 is a closed structure on both sides, or it can be a closed structure on one side. Example 2:
