Description

Technical Field

[0001] This utility model specifically relates to the field of tensioning mechanism technology, and more specifically to a transmission box-driven tensioning mechanism. Background Technology

[0002] In various types of mechanical equipment, the transmission system is a key component for realizing power transmission and motion control. As one of the core components of the transmission system, the gearbox's function is to transmit power from the power source to the working parts through different transmission methods to meet the different working requirements of the equipment.

[0003] During transmission, the tension of transmission components such as belts and chains has a crucial impact on the performance and reliability of the transmission system. Insufficient tension in transmission components can lead to slippage, reduced transmission efficiency, unstable equipment operating speed, or even malfunction. Slippage also accelerates wear on transmission components, shortening their lifespan. Conversely, excessive tension increases the load on the transmission system, leading to increased energy loss, accelerated fatigue damage to transmission components, and potentially causing equipment vibration and noise, affecting the overall performance of the equipment and the working environment.

[0004] Traditional transmission box tensioning methods often employ relatively simple structures, such as fixed tensioning wheels or devices for periodic manual tension adjustment. Once installed, a fixed tensioning wheel provides essentially a fixed tension, unable to adapt to tension variations caused by temperature changes, wear of transmission components, or other factors during transmission, easily leading to the aforementioned problems of insufficient or excessive tension. Periodic manual tension adjustment not only requires operators with specific professional knowledge and skills, but the process is also cumbersome, necessitating machine downtime and impacting normal production operation. Furthermore, the accuracy and reliability of manual adjustments are difficult to guarantee, easily resulting in improper tension adjustment due to human error. Utility Model Content

[0005] The purpose of this utility model is to provide a transmission box tensioning mechanism, which allows for free adjustment of the tension of the transmission belt by installing the tensioning mechanism with the transmission box, thereby achieving higher adjustment accuracy and reliability; thus solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A transmission box tensioning mechanism, comprising:

[0008] A transmission box, on which a tensioning mechanism is installed;

[0009] The tensioning mechanism includes a mounting plate with mounting holes at each of the four corners, and a sliding block and a screw block on the upper surface of the mounting plate, wherein the sliding block has a sliding cavity and the screw block has a thread.

[0010] As a further technical solution of this utility model, the screw block is threadedly connected to the screw, a rotary motor is installed at the other end of the screw, the other end of the rotary motor is connected to the slide rod, the slide rod is slidably connected to the slide cavity, and a limiting plate is provided at the other end of the slide rod.

[0011] As a further technical solution of this utility model, the upper ends of the slide block and the screw block are respectively axially connected to rotating blocks, the other ends of the two rotating blocks are axially connected to the connecting piece, one end of the connecting piece is axially connected to a connecting plate, and the other end of the connecting plate is connected to the shaft of the rotary motor.

[0012] As a further technical solution of this utility model, a bearing seat is provided at the center of the upper surface of the connecting member, the bearing seat is rotatably connected to the driven wheel, and a circular baffle is provided on the driven wheel.

[0013] As a further technical solution of this utility model, the transmission box includes multiple motors, which are connected to a transmission mechanism. The other end of the transmission mechanism is rotatably connected to a transmission wheel. A transmission belt is provided on the transmission wheel, and the other end of the transmission belt is connected to a driven wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, this utility model first connects the driven pulley to the transmission belt, which is driven to rotate by a motor. When the transmission belt is too tight with the driven pulley, the rotating motor drives the screw and thread to rotate. The screw moves towards the rotating motor, and the slide rod slides towards the limiting plate through the sliding cavity. When the rotating motor moves, it drives the connecting plate to rotate obliquely upward. The connecting plate then drives the connecting parts and the rotating block to rotate obliquely upward, thereby driving the bearing seat to rotate obliquely upward. The driven pulley is connected to the bearing seat and rotates obliquely upward, driving the transmission belt to reach a suitable tension. It can automatically adjust the tension according to the elongation or wear of the transmission belt, eliminating the need for frequent manual adjustments. This improves the reliability and stability of the transmission system and reduces problems such as transmission belt slippage and accelerated wear caused by insufficient tension.

[0016] 2. In this utility model, when the transmission belt and driven pulley are too loose, the rotary motor drives the screw and thread to rotate. The screw moves in the opposite direction of the rotary motor, and the slide rod slides in the direction of the rotary motor through the sliding cavity. When the rotary motor moves, it drives the connecting plate to rotate obliquely downward. The connecting plate then drives the connecting parts and rotating block to rotate obliquely downward, thereby driving the bearing seat to rotate obliquely downward. The driven pulley is connected to the bearing seat, and it rotates obliquely downward as well, driving the transmission belt to reach a suitable tension. The tensioning mechanism can precisely adjust the tension to meet the requirements of the transmission belt tension under different working conditions. This helps to improve transmission efficiency, reduce energy loss, and extend the service life of the transmission belt and transmission components. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4In this embodiment of the utility model, a transmission box tensioning mechanism includes a transmission box 1, on which a tensioning mechanism 2 is installed;

[0026] The tensioning mechanism 2 includes a mounting plate 21, which has mounting holes 22 at each of its four corners. The upper surface of the mounting plate 21 is provided with a sliding block 23 and a screw block 24, wherein the sliding block 23 has a sliding cavity 216 and the screw block 24 has a thread 215.

[0027] The screw block 24 is threadedly connected to the screw 25. A rotary motor 26 is installed at the other end of the screw 25. The other end of the rotary motor 26 is connected to the slide rod 27. The slide rod 27 is slidably connected to the slide cavity 216. A limiting plate 28 is provided at the other end of the slide rod 27.

[0028] The upper ends of the slide block 23 and the screw block 24 are respectively axially connected to the rotating blocks 29. The other ends of the two rotating blocks 29 are axially connected to the connector 210. One end of the connector 210 is axially connected to the side of the connecting plate 211. The other end of the connecting plate 211 is axially connected to the rotary motor 26.

[0029] By adopting the above technical solution, when the transmission belt 14 and the driven pulley 213 are too loose, the rotary motor 26 drives the screw 25 and the thread 215 to rotate. The screw 25 moves in the opposite direction to the rotary motor 26, and the slide rod 27 slides in the direction of the rotary motor 26 through the slide cavity 216. When the rotary motor 26 moves, it drives the connecting plate 211 to rotate obliquely downward. The connecting plate 211 then drives the connecting piece 210 and the rotating block 29 to rotate obliquely downward, thereby driving the bearing seat 212 to rotate obliquely downward. The driven pulley 213 is connected to the bearing seat 212, and the driven pulley 213 rotates obliquely downward, driving the transmission belt 14 to reach a suitable tension state. The tensioning mechanism 2 can precisely adjust the tension to meet the requirements of the transmission belt tension under different working conditions. This helps to improve transmission efficiency, reduce energy loss, and extend the service life of the transmission belt and transmission components.

[0030] In this embodiment, a bearing seat 212 is provided at the center of the upper surface of the connector 210. The bearing seat 212 is rotatably connected to the driven wheel 213, and a circular baffle 214 is provided on the driven wheel 213.

[0031] The transmission box 1 includes multiple motors 11, which are connected to a transmission mechanism 12. The other end of the transmission mechanism 12 is rotatably connected to a transmission wheel 13. A transmission belt 14 is provided on the transmission wheel 13, and the other end of the transmission belt 14 is connected to a driven wheel 213.

[0032] By adopting the above technical solution, during use, the driven wheel 213 is first connected to the transmission belt 14, which is driven to rotate by the motor 11. When the transmission belt 14 and the driven wheel 213 are too tight, the rotary motor 26 drives the screw 25 and the thread 215 to rotate. The screw 25 moves towards the rotary motor 26, and the slide rod 27 slides towards the limiting plate 28 through the slide cavity 216. When the rotary motor 26 moves, it drives the connecting plate 211 to rotate obliquely upward. The connecting plate 211 then drives the connecting piece 210 and the rotating block 29 to rotate obliquely upward, thereby driving the bearing seat 212 to rotate obliquely upward. The driven wheel 213 is connected to the bearing seat 212, and the driven wheel 213 rotates obliquely upward, driving the transmission belt 14 to reach a suitable tension. The tension can be automatically adjusted according to the elongation or wear of the transmission belt 14, eliminating the need for frequent manual adjustments. This improves the reliability and stability of the transmission system and reduces problems such as slippage and increased wear of the transmission belt 14 due to insufficient tension.

[0033] The working principle of this utility model is as follows: In use, the driven wheel 213 is first connected to the transmission belt 14, and the transmission belt 14 is driven to rotate by the motor 11. When the transmission belt 14 and the driven wheel 213 are too tight, the rotating motor 26 drives the screw 25 and the thread 215 to rotate. The screw 25 moves towards the rotating motor 26, and the slide rod 27 slides towards the limiting plate 28 through the sliding cavity 216. When the rotating motor 26 moves, it drives the connecting plate 211 to rotate obliquely upward. The connecting plate 211 then drives the connecting piece 210 and the rotating block 29 to rotate obliquely upward, thereby driving the bearing seat 212 to rotate obliquely upward. The driven wheel 213 is connected to the bearing seat 212, and the driven wheel 213 rotates obliquely upward, driving the transmission belt 14 to reach a suitable tension. It can automatically adjust the tension according to the elongation or wear of the transmission belt 14, without the need for frequent manual adjustment, which improves the reliability and stability of the transmission system and reduces problems such as slippage and accelerated wear of the transmission belt 14 due to insufficient tension.

[0034] When the drive belt 14 is too loose from the driven pulley 213, the rotary motor 26 drives the screw 25 and the thread 215 to rotate. The screw 25 moves in the opposite direction to the rotary motor 26, and the slide rod 27 slides in the direction of the rotary motor 26 through the slide cavity 216. When the rotary motor 26 moves, it drives the connecting plate 211 to rotate obliquely downward. The connecting plate 211 then drives the connecting piece 210 and the rotating block 29 to rotate obliquely downward, thereby driving the bearing seat 212 to rotate obliquely downward. The driven pulley 213 is connected to the bearing seat 212, and the driven pulley 213 rotates obliquely downward, driving the drive belt 14 to reach a suitable tension. The tensioning mechanism 2 can precisely adjust the tension to meet the requirements of the drive belt tension under different working conditions. This helps to improve transmission efficiency, reduce energy loss, and extend the service life of the drive belt and transmission components.
