Description

Technical Field

[0001] This utility model relates to the field of tensioner guide rail technology, and in particular to a low-resistance anti-shaking guide structure for tensioner guide rails. Background Technology

[0002] The existing technology has a large number of tensioner guides, which are mainly used in the field of traction drive devices. Traction drive devices use cyclic traction mechanisms, such as chains and belts. Tensioner guides control the chain by pre-tensioning the tensioner, thereby keeping the traction mechanism taut.

[0003] Existing tensioner guide rail structures mostly use rigid materials and lack effective drag reduction and buffer components. Due to the lack of materials with low friction coefficients, the friction force is large during operation, which not only leads to serious energy loss but also aggravates component wear and shortens the equipment maintenance cycle. At the same time, the rigid structure cannot absorb the vibration and impact force generated during operation, and the guide rail is prone to shaking, which reduces the transmission accuracy of the tensioner and may even cause equipment failure, affecting the continuity of production.

[0004] Therefore, those skilled in the art have provided a low-resistance anti-sway guide structure for tensioner guide rails to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-resistance, anti-shaking guide structure for tensioner guide rails. The elastic pad made of polytetrafluoroethylene (PTFE) reduces guide rail running resistance, energy consumption, and wear due to its low-friction characteristics. Simultaneously, its elastic buffer absorbs vibration, preventing guide rail swaying and ensuring smooth operation. The assembly mechanism uses snap-fit ​​slots and limiting structures to achieve rapid, precise installation and secure fixing of the elastic pad and baffle, improving assembly efficiency, simplifying maintenance procedures, and ensuring the elastic pad does not shift or fall off under complex working conditions. The combination of these two aspects significantly enhances the stability, reliability, and practicality of the guide structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A low-resistance anti-sway guide structure for a tensioner guide rail includes a baffle, an elastic pad is provided on the upper end face of the baffle, and an assembly mechanism is provided between the elastic pad and the baffle.

[0008] The assembly mechanism includes a plastic guide rail, with a first fixing buckle and a second fixing buckle fixedly connected to both sides of the lower end face of the plastic guide rail, and a first fixing slot and a second fixing slot respectively opened on both sides of the upper end face of the baffle, with the first fixing buckle and the second fixing buckle respectively engaging in the first fixing slot and the second fixing slot.

[0009] With the above technical solution, when installing the elastic pad, the No. 1 and No. 2 fixing buckles on the plastic guide rail are aligned with the No. 1 and No. 2 fixing slots on the baffle respectively to achieve tight fixation. When disassembling, external force is applied to make the buckles disengage from the slots, and the parts can be separated.

[0010] Furthermore, the elastic pad is made of polytetrafluoroethylene material;

[0011] Through the above technical solution, the elastic pad made of polytetrafluoroethylene comes into contact with the surface of the guide rail. Its low friction characteristics reduce the friction between the two, making the guide rail move more easily. When the vibration and impact force generated during operation are transmitted to the elastic pad, the elastic pad undergoes elastic deformation, absorbs the energy and converts it into its own deformation energy, thereby suppressing the shaking of the guide rail.

[0012] Furthermore, a first limiting plate is fixedly connected to one side of the lower end face of the plastic guide rail near the front and back, and a first limiting groove is opened on one side of the upper end face of the baffle near the front and back, and the first limiting plate is engaged in the first limiting groove.

[0013] The above technical solution achieves a better limiting effect by using the locking mechanism of the first limiting plate within the first limiting groove.

[0014] Furthermore, a second limiting plate is fixedly connected to the middle of the lower end face of the plastic guide rail near the front and rear, and a second limiting groove is opened in the middle of the upper end face of the baffle near the front and rear, and the second limiting plate is engaged in the second limiting groove.

[0015] The above technical solution achieves better restriction by engaging the second limiting plate within the second limiting groove.

[0016] Furthermore, a third limiting plate is fixedly connected to the lower end face of the plastic guide rail near the second fixing buckle at both the front and rear positions. A third limiting groove is opened on the upper end face of the baffle at both the front and rear positions. The third limiting plate is engaged and set in the third limiting groove.

[0017] The above technical solution achieves better restriction by engaging the No. 3 limiting plate within the No. 3 limiting slot.

[0018] Furthermore, an expansion block is movably fitted onto one side of the lower end face of the baffle;

[0019] Through the above technical solution, the set expansion block can push the relevant components of the tensioner guide rail system upward through its own elastic deformation or external force. That is, when the transmission system becomes loose or the tension changes due to long-term operation, the expansion block can automatically compensate for the gap and continuously maintain the stability of the tension, avoiding problems such as slippage, abnormal noise or reduced transmission efficiency caused by the loosening of transmission components, and ensuring that the tensioner is always in the best working condition.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model proposes a low-resistance anti-sway guide structure for a tensioner guide rail. The added elastic pad is made of polytetrafluoroethylene (PTFE). With its super-lubricating surface properties, it can greatly reduce the frictional resistance of the tensioner guide rail during operation, effectively reduce energy loss and component wear caused by friction, and extend the service life of the guide rail. At the same time, the elastic buffering performance of PTFE can effectively absorb the impact force caused by mechanical vibration and load changes during the operation of the guide rail, avoid abnormal swaying of the guide rail, ensure the smooth operation of the tensioner, and improve the overall stability and reliability of the system.

[0022] 2. This utility model proposes a low-resistance, anti-sway guide structure for tensioner guide rails. The assembly mechanism, through the precise matching design of multiple sets of buckles and slots, and limiting plates and slots, achieves rapid, accurate installation and firm fixation between the elastic pad and the baffle. This structure not only simplifies the assembly process, reduces installation difficulty, and improves assembly efficiency, but also ensures that the elastic pad will not shift or fall off due to vibration or external force during operation, guaranteeing the stability and reliability of the guide structure. At the same time, when maintenance or replacement of the elastic pad is required, it can be easily disassembled, which is convenient and quick, effectively reducing equipment maintenance costs and downtime.

[0023] 3. The tensioner guide rail low-resistance anti-shaking guide structure proposed in this utility model uses a polytetrafluoroethylene elastic pad to reduce the running resistance of the guide rail, reduce energy consumption and wear due to its low friction characteristics. At the same time, it absorbs vibration with elastic buffer to prevent the guide rail from shaking and ensure smooth operation. The assembly mechanism realizes the quick and accurate installation and firm fixation of the elastic pad and the baffle through the snap-lock and limit structure, which not only improves the assembly efficiency and simplifies the maintenance process, but also ensures that the elastic pad does not shift or fall off under complex working conditions. The combination of the two significantly enhances the stability, reliability and practicality of the guide structure. Attached Figure Description

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a specific embodiment: a low-resistance anti-sway guide structure for a tensioner guide rail, including a baffle 1. An elastic pad 2 is provided on the upper end face of the baffle 1. The elastic pad 2 is made of polytetrafluoroethylene (PTFE). The elastic pad 2, made of PTFE, contacts the guide rail surface. Its low friction characteristics reduce the friction between the two, making the guide rail move more easily. When the vibration and impact force generated during operation are transmitted to the elastic pad 2, the elastic pad 2 undergoes elastic deformation, absorbs energy and converts it into its own deformation energy, thereby suppressing the swaying of the guide rail. An assembly mechanism 3 is provided between the elastic pad 2 and the baffle 1. A tensioning block 4 is movably sleeved on one side of the lower end face of the baffle 1. Through the tensioning block 4, the relevant components of the tensioner guide rail system can be pushed upward by its own elastic deformation or external force. That is, when the transmission system becomes loose or the tension changes due to long-term operation, the tensioning block 4 can automatically compensate for the gap, continuously maintain the stability of the tension force, and avoid problems such as slippage, abnormal noise or reduced transmission efficiency caused by the loosening of transmission components, ensuring that the tensioner is always in the best working state.

[0032] Assembly mechanism 3 includes a plastic guide rail 303. A first fixing buckle 301 and a second fixing buckle 310 are fixedly connected to both sides of the lower end face of the plastic guide rail 303. A first fixing groove 302 and a second fixing groove 311 are respectively opened on both sides of the upper end face of the baffle 1. The first fixing buckle 301 and the second fixing buckle 310 are respectively engaged in the first fixing groove 302 and the second fixing groove 311. When installing the elastic pad 2, the first fixing buckle 301 and the second fixing buckle 310 on the plastic guide rail 303 are aligned with the first fixing groove 302 and the second fixing groove 311 on the baffle 1 to achieve tight fixation. Applying external force to disengage the buckles from the grooves allows the components to be separated. A first limiting plate 304 is fixedly connected to one side of the lower end face of the plastic guide rail 303 near the front and rear. A first limiting groove 305 is opened on one side of the upper end face of the baffle 1 near the front and rear. The first limiting plate 304 is engaged in the first fixing groove 305. The first limiting plate 304 is placed in the first limiting groove 305, and its engagement with the first limiting plate 304 within the first limiting groove 305 achieves a better limiting effect. A second limiting plate 306 is fixedly connected to the lower end face of the plastic guide rail 303 at both the front and rear positions. A second limiting groove 307 is provided at the upper end face of the baffle 1 at both the front and rear positions. The second limiting plate 306 is engaged within the second limiting groove 307. The internal locking mechanism can achieve a better limiting effect. The lower end face of the plastic guide rail 303 is fixedly connected to the front and rear sides of the side near the second fixing buckle 310. The upper end face of the baffle 1 is provided with the third limiting groove 309 at the front and rear sides. The third limiting plate 308 is locked in the third limiting groove 309. The locking mechanism of the third limiting plate 308 in the third limiting groove 309 can achieve a better limiting effect.

[0033] Working principle: When the guide structure is working, the PTFE elastic pad 2 utilizes its ultra-low coefficient of friction to form a smooth contact surface during the operation of the tensioner guide rail, greatly reducing frictional resistance. At the same time, it absorbs the impact force generated by mechanical vibration or load changes in the guide rail through elastic deformation, suppressing shaking. The assembly mechanism 3 achieves a stable connection between the elastic pad 2 and the baffle 1 through the elastic engagement of the first and second fixing buckles 310 with the corresponding slots, and the multi-directional positioning of the first, second, and third limiting plates 308 with the limiting slots. This ensures that the elastic pad 2 always maintains a precise position during operation, continuously exerting the low-resistance anti-shaking function. Moreover, the parts can be separated by overcoming the elasticity of the buckles during disassembly, facilitating maintenance and replacement.
