Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a multi-level tension adjustment structure for an air compressor. Background Technology

[0002] Traditional air compressor drive belt tension adjustment usually relies on manually adjusting the installation position of the drive components or changing the belt length to achieve limited fixed-gear tension control. The adjustment process is cumbersome, time-consuming, and requires machine shutdown, affecting equipment continuity. Furthermore, during equipment operation, tension attenuation caused by natural belt elongation or temperature changes cannot be compensated in real time, leading to reduced transmission efficiency, accelerated abnormal belt wear, and even slippage and loss of rotation. A single preload setting is difficult to adapt to the differentiated tension requirements of different load conditions. Under long-term equipment operation, excessive belt slack will increase transmission vibration and noise, while excessive belt tightness will accelerate bearing damage.

[0003] Therefore, in order to address the above problems, a multi-level tension adjustment structure for air compressors is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, this utility model provides a multi-level tension adjustment structure for an air compressor.

[0005] The technical solution of this utility model is: a multi-level tension adjustment structure for an air compressor, including a mounting base, an air compressor mounted on the upper left side of the mounting base, a first drive assembly connected to the air compressor on the upper right side of the mounting base, a protective assembly on the front side of the mounting base, a second drive assembly mounted on the upper front side of the mounting base, a worm gear connected to the output shaft of the second drive assembly, a mounting bracket on the top of the protective assembly, a bidirectional lead screw rotatably connected to the rear side of the protective assembly, the bidirectional lead screw rotatably connected to the mounting bracket, a worm wheel connected to the lower part of the bidirectional lead screw, the worm wheel meshing with the worm gear, a guide rod on the rear side of the protective assembly, the guide rod connected to the mounting bracket, two symmetrical mounting parts slidably connected to the guide rod, the mounting parts threadedly connected to the bidirectional lead screw, an adjusting roller rotatably connected to each mounting part, the adjusting roller contacting a corresponding belt, and a tension detection assembly on each mounting part.

[0006] Furthermore, the belt and drive wheel in the first drive assembly are both located within the protective assembly.

[0007] Furthermore, the protective component has ventilation holes on its front side.

[0008] Furthermore, the mounting bracket and the protective component have a detachable connection structure.

[0009] Furthermore, the worm gear and the bidirectional lead screw are perpendicular to each other.

[0010] Furthermore, the guide rod is located on the right side of the bidirectional lead screw.

[0011] By adopting the above technical solution, this utility model has the following advantages:

[0012] This invention utilizes a unique structure that drives a bidirectional lead screw via a worm gear transmission to precisely control the reverse displacement of symmetrically arranged mounting components, achieving continuous stepless adjustment of the gap between the two adjustable rollers. This provides the belt tension with multi-level precise control capabilities, significantly improving its adaptability to different load conditions and belt conditions. The dynamic feedback signal from the tension detection component forms a closed-loop control system that ensures the optimal tension value is maintained over a long period, effectively eliminating the risk of slippage and greatly extending the service life of the belt and bearings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0019] A multi-level tension adjustment structure for an air compressor, such as Figures 1-4As shown, the device includes a mounting base 1, an air compressor 2 mounted on the upper left side of the mounting base 1, a first drive assembly 3 mounted on the upper right side of the mounting base 1, the first drive assembly 3 connected to the air compressor 2, a protective assembly 4 mounted on the front side of the mounting base 1, the belt and drive wheel of the first drive assembly 3 located within the protective assembly 4, the protective assembly 4 having a vent hole on its front side, a second drive assembly 5 mounted on the upper front side of the mounting base 1, a worm gear 6 connected to the output shaft of the second drive assembly 5, a mounting bracket 10 mounted on the top of the protective assembly 4, the mounting bracket 10 and the protective assembly 4 having a detachable connection structure, and a rotating connection at the rear of the protective assembly 4. A bidirectional lead screw 8 is connected to the mounting bracket 10 in a rotatable manner. A worm gear 7 is connected to the lower part of the bidirectional lead screw 8. The worm gear 7 meshes with the worm 6. The worm 6 is perpendicular to the bidirectional lead screw 8. A guide rod 9 is provided on the rear side of the protective component 4. The guide rod 9 is connected to the mounting bracket 10. The guide rod 9 is located on the right side of the bidirectional lead screw 8. Two symmetrical mounting parts 11 are slidably connected to the guide rod 9. The mounting parts 11 are threadedly connected to the bidirectional lead screw 8. An adjusting roller 12 is rotatably connected to each mounting part 11. The adjusting roller 12 contacts the corresponding belt. A tension detection component 13 is provided on each mounting part 11.

[0020] It should be noted that the operation of the multi-level tension adjustment structure of the air compressor 2 begins with the power output generated after the air compressor 2 starts. The first drive assembly 3 receives the power from the air compressor 2 and drives the belt through the rotation of its active drive wheel. The belt then drives the driven device to realize power transmission. During operation, belt tension is a key factor in maintaining efficient transmission and preventing slippage. When it is necessary to adjust the belt tension, the operator or control system activates the second drive assembly 5, whose output shaft drives the worm 6 to rotate. Since the worm 6 and the worm wheel 7 are in a mutually perpendicular spatial position and achieve precise meshing, the rotation of the worm 6 drives the worm wheel 7 to rotate synchronously. The worm wheel 7 is rigidly connected to the lower end of the bidirectional lead screw 8, so the rotation of the worm wheel 7 is directly converted into bidirectional... The rotational motion of the lead screw 8 is achieved through a special design where two opposing threads are machined on its body. Two symmetrically arranged mounting pieces 11 engage with the corresponding threaded sections on the lead screw 8 via their internal threaded holes. Therefore, when the lead screw 8 rotates, the two mounting pieces 11 will generate opposite linear movements along the screw due to the opposite thread directions. When the screw rotates clockwise, one mounting piece 11 moves upwards while the other moves downwards; when the screw rotates counterclockwise, the movements are reversed. During this movement, the mounting pieces 11 are strictly constrained by the guide rod 9. The guide rod 9 is fixed to the protective assembly 4 and arranged parallel to the lead screw 8. Its smooth surface passes through the corresponding guide hole on the mounting piece 11, ensuring that the mounting piece 11 can only move along... Precise linear sliding along the axis of guide rod 9 completely eliminates the possibility of radial sway or offset, ensuring the stability and accuracy of the movement. Each mounting component 11 has a rotating connecting roller 12 at its front end. As the mounting components 11 move towards or away from each other under the drive of the bidirectional screw 8, the distance between the two rollers 12 changes accordingly (the distance decreases when moving towards each other and increases when moving away from each other). Since the working surface of the rollers 12 directly presses against the running belt (the belt is not the working surface), the change in the distance between the rollers 12 instantly alters the constraint shape and contact pressure on the belt. When the two rollers 12 approach each other, they force the belt sandwiched between them to locally bulge and bend, lengthening the path and effectively increasing... The overall tension of the belt is controlled by the tension of the belt. Conversely, when the two adjusting rollers 12 are moved away from each other, the local constraint on the belt decreases, the curvature decreases, and the path becomes shorter, which effectively reduces the belt tension. Thus, by precisely controlling the forward and reverse rotation angles and number of turns of the worm gear 6, worm wheel 7, and bidirectional lead screw 8 driven by the second drive assembly 5, fine, continuous, and multi-level adjustment (multi-gear) of the spacing between the adjusting rollers 12 can be achieved, thereby steplessly adjusting the belt tension to adapt to different load conditions or compensate for the natural elongation of the belt after long-term operation. Throughout the tension adjustment and equipment operation process, the tension detection assembly 13 installed on each mounting component 11 closely monitors the belt tension. This assembly includes strain gauges, pressure sensors, displacement sensors, and other components.The system directly or indirectly measures the force applied to the adjusting roller 12, the minute displacement of the adjusting roller 12, or the actual deflection change of the belt. The detected tension signal is converted into an electrical signal in real time and fed back to the control system. The operator can use this signal to confirm whether the current tension has reached the set target value. If the detected value deviates from the set value (e.g., insufficient tension due to belt wear and loosening), the control system will automatically send a command to the second drive assembly 5, driving the worm 6, worm wheel 7, and bidirectional lead screw 8 to rotate an appropriate angle, causing the adjusting roller 12 to move precisely until the tension detection signal matches the set value again, thus dynamically maintaining optimal tension. The protective assembly 4, as a key safety and protection structure, has its internal cavity completely enclosing the belt and drive wheel, and other high-speed rotating components in the first drive assembly 3, effectively preventing accidental contact by personnel and operational risks caused by foreign object intrusion. The front side of the protective assembly 4... The vent design promotes air circulation, effectively dissipating frictional heat and heat emitted by the air compressor 2, preventing overheating of components inside the protective cavity. The mounting bracket 10 on top of the protective assembly 4 is connected to it via a detachable connection structure, ensuring the stability of the mounting bracket 10 supporting the guide rod 9 and the upper end of the double-acting screw 8, while also facilitating disassembly for future maintenance of the internal components or the entire tension adjustment mechanism. The rear of the protective assembly 4 provides necessary installation space and protection for the lower part of the double-acting screw 8 and the worm gear 7 and worm 6 transmission pair. The entire device is integrated onto the mounting base 1, with the air compressor 2 and the first drive assembly 3 on the left, the second drive assembly 5 in front, and the protective assembly 4 in the center. The structure is compact, the functions are clear, and the device collaboratively achieves reliable power output from the belt drive, precise multi-level tension adjustment, effective assurance of operational safety, and real-time closed-loop monitoring of the status.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
