Description

Technical Field

[0001] This utility model relates to the field of toothed belt processing technology, and in particular to a toothed belt running-in mechanism. Background Technology

[0002] Toothed belt break-in refers to the process during the initial use of a newly installed toothed belt, where normal driving gradually adapts the belt to the toothed grooves of the pulley. During this stage, there are microscopic unevenness on the contact surfaces between the belt and the pulley, resulting in slight friction and deformation during operation. The purpose of break-in is to allow the belt teeth and pulley teeth to form a tighter mesh, reduce operating noise, lower the risk of early wear caused by concentrated contact stress, and stabilize the belt tension. During the break-in period, it is necessary to avoid rapid acceleration, sudden braking, and high-load operation, and to regularly check the belt tension to ensure smooth operation of the transmission system and extend the belt's service life.

[0003] Newly manufactured toothed belts or those reused after long periods of inactivity often have less than ideal tooth profiles that fit the gears. If put directly into use, this can lead to slippage, vibration, and increased noise during transmission. This not only affects transmission stability but also accelerates belt and gear wear, reduces equipment lifespan, increases maintenance costs, and poses production safety hazards. However, existing toothed belt break-in mechanisms have a fixed distance between the two gears, requiring significant tension to fit the belt onto the gears during installation, making the operation difficult. Furthermore, the motor is not speed-adjustable, limiting belt break-in to a single speed, which makes it difficult to control various parameters during the break-in process, such as break-in speed and break-in time, resulting in unsatisfactory break-in results.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1: Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a toothed belt running-in mechanism, including a base plate 1, a base 2 fixedly installed on the top of the base plate 1, a drive component 3 provided on the inner wall of the base 2, and a first fixed gear 4 fixedly provided at the output end of the drive component 3.

[0025] The base plate 1 serves as the foundation of the entire running-in mechanism, providing a basic platform for the installation and fixation of all other components, ensuring the relative position stability of each component during operation. The base 2 is set to provide installation space for the drive assembly 3, protect the drive assembly 3 and ensure its stable operation. The drive assembly 3 serves as the power source of the entire running-in mechanism, driving the first fixed gear 4 to rotate, thereby driving other related components to move and realize the belt running-in operation. The first fixed gear 4 cooperates with the second fixed gear 8, and through the meshing transmission between the gears, it is used to transmit the power from the drive assembly 3 to the second fixed gear 8, realizing the transmission and conversion of power, driving the related components to move, and making the belt run-in under the drive of the gears.

[0026] A movable plate 5 is slidably connected to the top of the base plate 1. A first support seat 6 is fixedly installed on the top of the movable plate 5. A second rotating rod 7 is rotatably connected to the inner wall of the first support seat 6. A second fixed gear 8 is fixed at one end of the second rotating rod 7. The axes of the first fixed gear 4 and the second fixed gear 8 are parallel. A speed regulator body 9 that is communicatively connected to the drive assembly 3 is installed on the top of the base plate 1.

[0027] The movable plate 5 slides on the slide rail 17 via the slider 18, which drives the first support seat 6 and the second fixed gear 8 mounted on its top to perform linear motion. This adjusts the relative position between the second fixed gear 8 and the first fixed gear 4 to accommodate the break-in requirements of belts of different lengths or specifications. The first support seat 6 provides support and fixation for the second rotating rod 7, ensuring its stable rotation and thus enabling the second fixed gear 8 to work stably. The second rotating rod 7 transmits the motion of the movable plate 5 to the second fixed gear 8 and supports it to rotate normally. The second fixed gear 8, through meshing with the first fixed gear 4, can rotate under the drive of the first fixed gear 4. Simultaneously, it contacts the belt, and through friction and meshing with the belt, the belt is broken in. The speed regulator body 9 is set to adjust the speed of the speed regulating motor 31. The operator can control the output speed of the drive component 3 through the speed regulator body 9 according to the actual break-in situation, thereby optimizing the belt break-in effect. It should be noted that the working principle of the speed regulator body 9 in this case is the same as the working principle of the speed regulator in https: / / baike.baidu.com / item / %E8%B0%83%E9%80%9F%E5%99%A8?fromModule=lemma_search-box, which is existing technology and will not be described again here.

[0028] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, the drive assembly 3 includes a speed-regulating motor 31 installed on the inner wall of the base 2. The output end of the speed-regulating motor 31 is fixed with a coupling body 32. The output end of the coupling body 32 is fixed with a first rotating rod 33, and one end of the first rotating rod 33 is fixedly connected to the shaft of the first fixed gear 4.

[0030] The speed-regulating motor 31 is used to provide power with adjustable speed, and can adjust the output speed according to different break-in requirements to adapt to belt break-in of different specifications and requirements. The model of the speed-regulating motor 31 is YCT-112-4A, which is an electromagnetic speed-regulating three-phase asynchronous motor. The coupling body 32 is used to connect the speed-regulating motor 31 and the first rotating rod 33, which plays the role of transmitting torque. At the same time, it can compensate for the displacement deviation between the two shafts to a certain extent, reduce vibration and impact, and protect the motor and transmission components. The first rotating rod 33 is used to transmit the power transmitted by the coupling body 32 to the first fixed gear 4, driving the first fixed gear 4 to rotate. It should be noted that the working principle of the coupling body 32 in this case is the same as the working principle of the coupling in https: / / baike.baidu.com / item / %E8%81%94%E8%BD%B4%E5%99%A8?fromModule=lemma_search-box, which is existing technology and will not be described again here.

[0031] Specifically, a spacing adjustment mechanism is installed on the base plate 1, and the spacing adjustment mechanism is connected to the movable plate 5 via a transmission. The spacing adjustment mechanism includes a fixed block 10, a limiting seat 11, a handle 12, a connecting block 13, and a top rod 14. The bottom of the fixed block 10 is fixedly connected to the top of the base plate 1, the bottom of the limiting seat 11 is fixedly connected to the top of the fixed block 10, one end of the handle 12 is hinged to the inner wall of the limiting seat 11, one end of the connecting block 13 is hinged to the middle of the handle 12, and the other end is hinged to one end of the top rod 14. The other end of the top rod 14 is hinged to one side of the movable plate 5. The spacing adjustment mechanism is a cylinder, a hydraulic cylinder, or a linear motor.

[0032] The fixed block 10 is set to provide an installation base for the limit seat 11, ensuring the stability of the limit seat 11. The limit seat 11 is set to provide a support point for the handle 12 and restrict the rotation of the handle 12 within a certain range. At the same time, it transmits the movement of the handle 12 to the connecting block 13. The operator can rotate the handle 12 to drive the connecting block 13 to move, and then push the movable plate 5 to move through the push rod 14, so as to realize the manual adjustment of the position of the movable plate 5. The connecting block 13 is set to convert the rotational movement of the handle 12 into the linear movement of the push rod 14, realizing the transmission and conversion of movement. Under the drive of the connecting block 13, the push rod 14 makes a linear movement and pushes the movable plate 5, so that the movable plate 5 slides on the slide rail 17, thereby adjusting the position of the second fixed gear 8.

[0033] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] Specifically, a second support seat 15 for supporting the first rotating rod 33 is installed on the top of the base plate 1 by screws, and the inner wall of the second support seat 15 is rotatably connected to the outer side of the first rotating rod 33. A mounting seat 16 for installing the speed controller body 9 is installed on the top of the base plate 1 by screws.

[0035] The second support seat 15 is provided to provide additional support for the first rotating rod 33, enhance the stability of the first rotating rod 33, reduce its vibration and deformation during rotation, and ensure the smooth operation of the transmission device. The mounting seat 16 is provided to provide a fixed installation position for the speed regulator body 9, ensuring the stability and reliability of the speed regulator body 9 during operation.

[0036] Specifically, the top of the base plate 1 is equipped with two sets of symmetrically designed slide rails 17. The outer side of the slide rails 17 is slidably connected to a slider 18, and the top of the slider 18 is fixedly connected to the bottom of the movable plate 5 by screws.

[0037] The slide rail 17 is provided to provide a track for the linear motion of the slider 18, ensuring the straightness and stability of the movable plate 5 during the sliding process, so that the movable plate 5 can move in a predetermined direction, thereby adjusting the position of the second fixed gear 8. The slider 18 is provided to connect the movable plate 5 to the slide rail 17, so that the movable plate 5 can slide smoothly on the slide rail 17, while restricting the movement of the movable plate 5 in the direction of the slide rail 17.

[0038] Specifically, the inner wall of the base plate 1 is provided with four sets of mounting holes 19, and the mounting holes 19 are distributed at the four corners of the base plate 1. Two sets of handles 20 are fixed on the top of the base plate 1.

[0039] The mounting hole 19 is used to fix the entire toothed belt running-in mechanism to other equipment or workbench to ensure the stability and safety of the mechanism during operation. The handle 20 makes it convenient for operators to carry and move the entire running-in mechanism, improving the portability and flexibility of the equipment.

[0040] Specifically, a positioning plate 21 is fixed to the top of the base plate 1, and a horizontally arranged positioning bolt 22 is threaded to the inner wall of the positioning plate 21, with one end of the positioning bolt 22 threaded to the inner wall of the movable plate 5.

[0041] The positioning plate 21 is fixed on the base plate 1 to provide an installation base for the positioning bolt 22. Since the positioning bolt 22 is threaded to the inner wall of the movable plate 5, the position of the movable plate 5 can be fixed by rotating the positioning bolt 22 to prevent it from sliding during operation, ensuring that the relative position of the second fixed gear 8 and the first fixed gear 4 is stable, and ensuring that the break-in operation is carried out smoothly.

[0042] Working principle: When the toothed belt running-in mechanism is working, firstly, the device is securely installed on a suitable workbench through the mounting holes 19 at the four corners of the base plate 1. Then, according to the specifications of the belt to be run-in, the position of the movable plate 5 is adjusted. The operator rotates the handle 12 on the limit seat 11, which drives the connecting block 13 to move. The connecting block 13 then pushes the push rod 14. Since one end of the push rod 14 is fixedly connected to one side of the movable plate 5, it can push the movable plate 5 to slide on the slide rail 17 with the help of the slider 18. This moves the second rotating rod 7 and the second fixed gear 8 installed in the first support seat 6 on the movable plate 5 to the appropriate position, allowing the second fixed gear 8 to cooperate with the first fixed gear 4 to clamp the belt. Then, the speed regulator body 9 is started, and the speed regulator body 9 is used to set the speed. When the speed-regulating motor 31 reaches the appropriate speed, it starts running. Its output power is transmitted to the first rotating rod 33 via the coupling body 32. The first rotating rod 33 rotates stably under its own rotational support and the rotational support of the second support seat 15, thereby driving the first fixed gear 4 to rotate. The first fixed gear 4 and the second fixed gear 8 are driven by gear meshing, so that the second fixed gear 8 rotates synchronously. At this time, the belt sandwiched between the two gears starts to run and rub under the drive of the gears, realizing the break-in operation. During the break-in process, the speed of the speed-regulating motor 31 can be adjusted at any time through the speed regulator body 9 according to the actual break-in condition of the belt to obtain the best break-in effect. If the mechanism needs to be moved, the operator can hold the handle 20 on the top of the base plate 1 to easily move the mechanism to other positions.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
