Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a noise-reducing compressor main housing. Background Technology

[0002] Compressors generate continuous and complex mechanical vibrations during operation. This vibration energy propagates outwards through the casing structure, increasing overall noise levels and potentially causing loosening of fixed components, structural fatigue, and resonance in surrounding equipment. Therefore, effectively reducing vibration transmission and improving the vibration isolation and noise reduction capabilities of the main casing is one of the key technologies in compressor structural design.

[0003] In existing technologies, the bottom of the compressor casing is typically fixed in place using rigid connections, such as integral welded base plates, rigid metal legs, or rubber damping blocks. While rigid metal connections offer relatively stable load-bearing capacity, they lack elastic cushioning, allowing vibrations to be directly transmitted to the casing and external mounting structures, resulting in poor noise suppression. Rubber damping pads can provide some vibration isolation, but they are prone to aging, permanent deformation, or failure under high-frequency vibration and long-term compression conditions. Furthermore, rubber materials exhibit inconsistent responses to multi-directional vibrations, limiting their vibration isolation effectiveness.

[0004] Existing compressor vibration damping structures also employ elastic metal supports or corrugated sheet structures, providing flexible support through thin-walled elastic elements. However, such structures generally exhibit unidirectional deformation, allowing only vertical elastic deformation, making it difficult to simultaneously cope with combined radial and tangential vibrations. Furthermore, some structures rely on a single elastic element for support, resulting in concentrated stress, shorter lifespan, and insufficient stability.

[0005] On the other hand, the connection between the compressor main casing and the vibration damping structure is usually a planar support or a simple interlocking, lacking an effective limiting and guiding mechanism. When the compressor generates large vibrations, the vibration damping components are prone to displacement or tilting, thereby affecting the vibration isolation effect and even causing casing shaking or abnormal noise.

[0006] In summary, the existing technologies generally have the following shortcomings: (1) Most of the damping structures are unidirectional buffers and cannot absorb composite vibrations from multiple directions at the same time; (2) The elastic components have weak distributed support capabilities and low vibration energy absorption efficiency; (3) The lack of a stable limiting mechanism makes the damping components prone to positional displacement during operation; (4) It is difficult to achieve an effective balance between the overall stiffness and flexibility of the support structure, resulting in limited noise suppression capabilities.

[0007] Therefore, there is an urgent need for a noise-reducing compressor main casing structure that is structurally stable, has multi-directional elastic buffering capabilities, and can achieve swing limit and long-term operational reliability, in order to solve the above-mentioned problems existing in the current vibration reduction technology. Utility Model Content

[0008] This invention aims to solve the problems of insufficient multi-directional vibration isolation capability, easy displacement of damping components, and inadequate noise suppression in existing compressor main housing structures. It provides a noise-reducing compressor main housing with a stable structure, multi-directional flexible support, and highly reliable vibration damping effect. This invention forms a synergistic buffer system through a fixed base, floating base, swing base, and elastic swing assembly, enabling the vibrations generated by the compressor during operation to be fully absorbed and attenuated, thereby significantly reducing noise and improving overall operational stability.

[0009] The overall structure of this utility model is as follows: a noise-reducing compressor main housing, including the main housing and a multi-level flexible support component installed at the bottom of the main housing. The three-dimensional vibration buffer and limiting guidance are achieved through a combination structure of swing grooves, joint edges, arch blocks, and spring sheets, ensuring the stability of the shock absorber during long-term operation.

[0010] In a preferred embodiment, the present invention provides a noise-reducing compressor main housing, comprising a main housing and a support member fixedly installed on the bottom surface of the main housing. The support member includes a fixed base, a float base, a swing base, and several elastic swing groups.

[0011] The float is fixedly installed on the bottom surface of the main housing to receive the primary vibration during compressor operation; the fixed seat is arranged opposite to the float, and their opposite surfaces are respectively provided with swing grooves and joint edges to form a guide structure for bidirectional upper and lower positioning.

[0012] The upper and lower arched ends of the pendulum seat are respectively movably fitted into the inner side of the pendulum groove, so that the pendulum seat can swing at a small angle under the action of external force.

[0013] Several flexible pendulum groups are arranged between the fixed base, the floating base, and the pendulum base, with their upper and lower ends respectively engaging with the opposite surfaces of the three. Each flexible pendulum group consists of two arched blocks and several cross-arranged spring plates. The spring plates have an S-shaped structure and are used to provide flexible buffering capabilities in the vertical, radial, and tangential directions.

[0014] Specifically, through the combination of multi-level flexible structures, vibrations are dispersed and absorbed in multiple directions, significantly reducing the noise transmission of the main shell.

[0015] In a preferred example, the outer periphery of the fixed base is provided with several feet for reliably installing the support in the fixed position of the compressor, thereby achieving structural positioning and force balance.

[0016] Specifically, the support components can maintain a stable posture during operation, avoiding displacement or tilting caused by vibration, thus improving structural safety.

[0017] In a preferred example, the engagement edges on the surfaces of the fixed seat and the float are arranged in mutually perpendicular directions, so that the engagement edges form a two-dimensional limit on the swing seat.

[0018] The pendulum base is composed of two mutually perpendicular arched frames, with the upper and lower arched surfaces abutting against the corresponding joint edges, allowing the pendulum base to obtain a controlled swing space in three dimensions.

[0019] Specifically, the sway of the pendulum is limited to a controllable range, making the vibration buffering process stable and linear, and preventing excessive amplification of vibration.

[0020] In a preferred example, the arch blocks are arc-shaped strip structures, and two arch blocks abut against each other to form an arc-shaped skeleton, which supports the spring pieces and keeps the overall shape of the elastic pendulum stable.

[0021] Specifically, the arch provides a mounting reference for the spring sheet, ensuring that the elastic pendulum assembly is subjected to uniform force and avoids displacement, thereby improving the durability of the buffer structure.

[0022] In a preferred example, the springs are made of metal springs arranged in a crisscross pattern along the outer side of the arch. The metal springs are capable of elastic deformation in multiple directions, thus providing cushioning capabilities in the vertical, radial, and tangential directions.

[0023] Specifically, by using the multi-directional deformation modes of the spring, complex vibrations are decomposed and absorbed, causing the vibration energy to decay step by step, thus achieving a significant noise reduction effect.

[0024] In a preferred example, the surface of the elastic pendulum assembly has a groove that matches the pendulum groove, so that the elastic pendulum assembly can be stably engaged inside the pendulum groove and maintain a fixed position under vibration.

[0025] Specifically, this prevents the elastic pendulum from slipping or loosening during long-term vibration, thereby improving the reliability and lifespan of the damping structure.

[0026] In a preferred example, the fixed base and the floating base are in the shape of a disc, and the bottom surface of the main housing is provided with a cylindrical receiving groove to accommodate the support members to form an embedded installation method.

[0027] Specifically, the embedded installation makes the bottom structure of the main housing more compact, lowers the overall center of gravity, and further improves the stability and noise reduction performance of the compressor during operation.

[0028] The beneficial effects achieved by this utility model are as follows:

[0029] 1. In this utility model, a multi-directional flexible support structure is formed by the swing groove, the connecting edge and the elastic swing group between the fixed seat, the floating seat and the swing seat, so that the vibration from the compressor operation process can be dispersed and absorbed in the vertical, radial and tangential directions, significantly reducing the transmission of vibration energy to the main shell and the external structure, thereby effectively reducing the noise of the whole machine.

[0030] 2. In this utility model, the elastic pendulum assembly is composed of an arch block and cross-arranged S-shaped spring pieces, which can provide highly sensitive buffering and recovery performance in the case of slight deformation, making the swing of the pendulum seat more stable. At the same time, the slot structure ensures that the elastic pendulum assembly is stably embedded, avoiding displacement deviation, improving the overall structural reliability of the support component, and enabling the compressor to still have excellent shock absorption and noise reduction effects during long-term operation.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0040] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0041] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a noise-reducing compressor main housing.

[0042] Combination Figures 1-5As shown, the present invention provides a noise-reducing compressor main housing, including a main housing 100 and a support member 200 fixedly installed on the bottom surface of the main housing 100. The support member 200 is used to provide multi-directional vibration damping support during compressor operation to reduce the transmission of vibration to the main housing 100 and external equipment.

[0043] In this embodiment, the support member 200 includes a fixed base 210, a float 220, a swing base 230, and several elastic swing groups 240. The float 220 is fixedly installed on the bottom surface of the main housing 100 and directly connected to the compressor body, serving to bear the vertical load from the compressor. The fixed base 210 is disposed below the float 220, with the two arranged opposite each other, providing a positioning reference for the swing mechanism and the elastic swing groups 240.

[0044] like Figure 2 , Figure 3 As shown, the opposing surfaces of the fixed base 210 and the float 220 are respectively provided with a swing groove 221 and a connecting ridge 222. The swing groove 221 has an arc-shaped groove structure along the surface of the fixed base 210, which is used to provide a movable fitting space for the arched end of the swing base 230; the connecting ridge 222 has a raised ridge structure along the surface of the float 220, which abuts against the other arched surface of the swing base 230, so that the swing base 230 obtains bidirectional limiting and guidance when subjected to force.

[0045] like Figures 2 to 4 As shown, the swing seat 230 is a curved arch structure with symmetrical upper and lower arched surfaces. Its upper and lower ends are respectively movably sleeved on the inner side of the swing groove 221. When subjected to external force, it can tilt and swing slightly along the arch structure, thereby realizing flexible support during the operation of the compressor.

[0046] Several elastic pendulum assemblies 240 are disposed between the fixed base 210, the float 220, and the pendulum base 230, and are interlocked with the three to form an elastic support system. Each elastic pendulum assembly 240 includes two arch blocks 241 and several cross-arranged spring pieces 242. The arch blocks 241 are arc-shaped strips, and two arch blocks 241 abut against each other to form an arc-shaped covering frame, providing a mounting base for the spring pieces 242. The spring pieces 242 have an S-shaped steel sheet structure, which is longitudinally bent and laterally staggered, and can provide buffering, flexible deformation, and restoring force in multiple directions.

[0047] like Figure 5 As shown, the outer surface of the elastic pendulum assembly 240 is provided with a slot that matches the pendulum groove 221, so that the elastic pendulum assembly 240 can be stably embedded in the inner side of the pendulum groove 221, preventing slippage or displacement during vibration or load changes of the main housing 100.

[0048] In this embodiment, as Figure 1As shown, the outer periphery of the fixed base 210 is provided with several support legs 211, which are used to fix the support member 200 as a whole on the mounting base, thereby improving the support stability of the compressor operation. The fixed base 210 and the float 220 are generally in a disc-shaped structure, and the bottom surface of the main housing 100 is provided with a cylindrical receiving groove, so that the support member 200 can be embedded in the bottom of the main housing 100, reducing exposed parts and improving the overall structural compactness.

[0049] Through the above structural combination, the support member 200 forms a multi-directional elastic support system with the swing seat 230 as the medium, the elastic swing group 240 as the buffer core, and the fixed seat 210 and the floating seat 222 as the limiting reference. It can effectively isolate the vibration energy generated during the operation of the compressor and reduce noise diffusion.

[0050] Working principle:

[0051] This invention achieves multi-directional buffering and noise suppression of compressor vibration through the synergistic effect of the fixed base 210, the floating base 220, the swing base 230 and the elastic swing group 240.

[0052] When the compressor is running, the vibration is first received by the float 220 and then transmitted to the swing seat 230 through the connecting edge 222. Since the upper and lower arched surfaces of the swing seat 230 are respectively fitted into the swing groove 221, it can generate a tilting motion along the arched surface within a small range, thereby converting the vibration into a controllable displacement.

[0053] Subsequently, the displacement generated by the pendulum seat 230 acts on several elastic pendulum groups 240. The arch block 241 in the elastic pendulum group 240 provides a supporting frame for the spring piece 242, and the S-shaped spring piece 242 undergoes elastic deformation after being subjected to force. Since the spring piece 242 adopts a cross-arranged structure, it can provide elastic restoring force in different directions in the vertical, radial, and tangential directions, so that the vibration energy is dispersed and absorbed in multiple directions.

[0054] The elastic pendulum assembly 240 is stably embedded in the pendulum groove 221 through the slot structure, so that it always maintains uniform force during vibration transmission and will not shift or detach, thereby ensuring the long-term reliability of the support system.

[0055] Meanwhile, the outer peripheral support 211 of the fixed base 210 further transmits the vibration to the installation foundation, while the flexible structure formed by the elastic pendulum group 240 and the pendulum base 230 has fully buffered the vibration, significantly reducing the vibration transmitted to the foundation and greatly reducing the overall noise.

[0056] In addition, the fixed base 210 and the floating base 220 adopt a disc-shaped structure, and the bottom of the main housing 100 is provided with an embedded receiving groove, which lowers the overall center of gravity and makes the structure more stable, which is conducive to further suppressing the resonance effect caused by the high-frequency vibration of the compressor.

[0057] In summary, the vibration damping structure of this utility model utilizes a synergistic mechanism of multi-stage elasticity, flexible oscillation, and limiting guidance to effectively absorb, attenuate, and isolate vibrations during compressor operation, achieving a significant noise reduction effect.
