Description

Technical Field

[0001] This utility model relates to the field of mechanical timing belt technology, and in particular to an anti-slip timing belt suitable for heavy machinery. Background Technology

[0002] In heavy machinery transmission systems, synchronous belts are an important transmission component widely used in various power transmission applications. However, traditional synchronous belts often face problems such as unstable tension and poor heat dissipation during use, which seriously affects their transmission efficiency and service life.

[0003] On the one hand, traditional synchronous belts lack an effective tension adjustment mechanism. Under prolonged operation or with significant load variations, synchronous belts are prone to slippage due to insufficient tension. This not only reduces transmission efficiency but may also lead to mechanical failures. On the other hand, synchronous belts generate a large amount of heat during high-speed operation. If this heat cannot be dissipated in time, it will accelerate the aging of the synchronous belt material and shorten its service life.

[0004] To solve the above problems, there is a need for an anti-slip synchronous belt suitable for heavy machinery that is simple in structure, easy to operate, can effectively adjust tension, and improve heat dissipation. Utility Model Content

[0005] This utility model discloses an anti-slip synchronous belt suitable for heavy machinery. To achieve the above objective, this utility model adopts the following technical solution:

[0006] An anti-slip synchronous belt suitable for heavy machinery includes a protective shell, a first synchronous pulley and a second synchronous pulley are rotatably connected to the inner wall of the protective shell, a synchronous belt body is installed between the first synchronous pulley and the second synchronous pulley, and a tensioning mechanism and a heat dissipation mechanism are provided on the surface of the protective shell.

[0007] The tensioning mechanism includes an adjustment box fixedly connected to the back of the protective shell. An adjustment motor is fixedly mounted on the lower surface of the adjustment box. The rotating shaft of the adjustment motor extends into the interior of the adjustment box and is fixedly connected to a tensioning screw. A movable plate is threaded onto the surface of the tensioning screw. Limiting blocks are fixedly connected to both sides of the movable plate. A U-shaped movable frame is fixedly mounted on the surface of the two limiting blocks. The front end of the movable frame extends into the interior of the protective shell, and a tensioning wheel is rotatably connected to the surface of the movable frame. The tensioning wheel overlaps with the surface of the synchronous belt body. A pressure sensor is fixedly connected to the inner wall of the protective shell. A detection shaft is fixedly mounted on the detection end of the pressure sensor. A movable support roller 509 is rotatably connected to the surface of the detection shaft, and the movable support roller overlaps with the lower surface of the synchronous belt body.

[0008] In a preferred embodiment, the protective shell has two strip-shaped limiting holes on its back side, the positions of which correspond to the movable frame, and the limiting blocks are slidably connected to the inner walls of the strip-shaped limiting holes.

[0009] In a preferred embodiment, the heat dissipation mechanism includes an air intake filter box fixedly installed on the left side surface of the protective shell. The left side of the protective shell has a plurality of air intake holes, the positions of which correspond to the air intake filter box.

[0010] In a preferred embodiment, a filter screen is installed inside the air intake filter box, and a cover plate is fixedly installed on the left side of the air intake filter box by bolts. A ventilation opening is provided on the surface of the cover plate, and an air intake fan is fixedly installed on the surface of the cover plate. The air outlet of the air intake fan corresponds to the ventilation opening.

[0011] In a preferred embodiment, the protective shell has several heat dissipation holes on its right side, and a dustproof mesh is fixedly connected to the inner wall of the heat dissipation holes.

[0012] In a preferred embodiment, the synchronous belt body is made of hydrogenated nitrile rubber, and a sealing plate is fixedly installed on the front of the protective shell.

[0013] As can be seen from the above, the anti-slip synchronous belt for heavy machinery provided by this utility model has the following technical effects.

[0014] Firstly, by installing a tensioning mechanism inside the synchronous belt protective shell, the movable support roller on the surface of the detection shaft can limit and support the surface of the synchronous belt body, and the pressure sensor can detect the pressure on the surface of the movable support roller. When the tension of the synchronous belt body decreases, the adjusting motor can be started to drive the tensioning screw to rotate, which in turn drives the moving frame to move upward inside the protective shell, and at the same time drives the tensioning wheel to perform tensioning operation on the synchronous belt body, so as to achieve the purpose of real-time monitoring and adjustment of the synchronous belt tension.

[0015] Secondly, by installing a protective shell on the outside of the synchronous belt, the protective shell can be used to prevent dust from entering the synchronous belt. By setting up a heat dissipation mechanism, during the operation of the synchronous belt, the intake fan can be used to input external air into the intake filter box, and the filter screen inside the intake filter box can then be used to remove dust from the intake air. The intake holes can then be used to ventilate the inside of the protective shell, and the heat dissipation holes can be used to exhaust heat to the outside. This achieves ventilation and heat dissipation while ensuring the dustproof and anti-fouling effect on the synchronous belt. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1 and Figure 2 A type of anti-slip synchronous belt suitable for heavy machinery includes a protective shell 1. A first synchronous pulley 2 and a second synchronous pulley 3 are rotatably connected to the inner wall of the protective shell 1. A sealing plate 8 is fixedly installed on the front of the protective shell 1. A synchronous belt body 4 is installed between the first synchronous pulley 2 and the second synchronous pulley 3. The synchronous belt body 4 is made of hydrogenated nitrile butadiene rubber. It should be noted that hydrogenated nitrile butadiene rubber is a high-performance material widely used in synchronous belts. It has good high temperature resistance, excellent oil resistance and chemical corrosion resistance, and good mechanical properties, with high strength, elasticity and wear resistance.

[0025] Reference Figure 3 and Figure 4In a preferred embodiment, the surface of the protective shell 1 is provided with a tensioning mechanism 5 and a heat dissipation mechanism 6. The heat dissipation mechanism 6 includes an air intake filter box 601 fixedly installed on the left side surface of the protective shell 1. The left side of the protective shell 1 has a plurality of air intake holes 602, the positions of which correspond to the air intake filter box 601. The right side of the protective shell 1 has a plurality of heat dissipation holes 606, and a dustproof net is fixedly connected to the inner wall of the heat dissipation holes 606. The dustproof net can protect the air intake holes 602 from dust, preventing external dust from entering the interior of the protective shell 1 through the air intake holes 602.

[0026] It should be further explained that a filter screen 603 is installed inside the air intake filter box 601. A cover plate 604 is fixedly installed on the left side of the air intake filter box 601 by bolts. A vent is opened on the surface of the cover plate 604, and an air intake fan 605 is fixedly installed on the surface of the cover plate 604. The air outlet of the air intake fan 605 corresponds to the vent. The air intake fan 605 inputs external air into the air intake filter box 601 through the vent.

[0027] It is worth noting that by setting a protective shell 1 on the outside of the synchronous belt, the protective shell 1 can be used to prevent dust from entering the synchronous belt. By setting a heat dissipation mechanism 6, during the operation of the synchronous belt, the intake fan 605 can be used to input external air into the intake filter box 601, and the filter screen 603 inside the intake filter box 601 can be used to remove dust from the intake air. Then, the intake hole 602 is used to ventilate the inside of the protective shell 1, and the heat dissipation hole 606 is used to exhaust heat to the outside. While achieving ventilation and heat dissipation, the dust prevention and anti-fouling effect of the synchronous belt is guaranteed.

[0028] Reference Figure 2 and Figure 4 In a preferred embodiment, the tensioning mechanism 5 includes an adjustment box 501 fixedly connected to the back of the protective shell 1. An adjustment motor 502 is fixedly provided on the lower surface of the adjustment box 501. The rotation shaft of the adjustment motor 502 extends into the interior of the adjustment box 501 and is fixedly connected to a tensioning screw 503. A movable plate 504 is threadedly connected to the surface of the tensioning screw 503. Limiting blocks 510 are fixedly connected to both sides of the movable plate 504.

[0029] It should be noted that two strip-shaped limiting holes 7 are provided on the back of the protective shell 1. The position of the strip-shaped limiting holes 7 corresponds to the moving frame 505. The limiting block 510 is slidably connected to the inner wall of the strip-shaped limiting hole 7. The strip-shaped limiting hole 7 can be used to guide and limit the limiting block 510, so that the movable plate 504 can move stably up and down on the surface of the tension screw 503.

[0030] Two limiting blocks 510 have U-shaped movable frames 505 fixed to their surfaces. The front end of the movable frames 505 extends into the interior of the protective shell 1. A tensioning wheel 506 is rotatably connected to the surface of the movable frames 505. The tensioning wheel 506 overlaps with the surface of the synchronous belt body 4. A pressure sensor 507 is fixedly connected to the inner wall of the protective shell 1. A detection shaft 508 is fixedly provided at the detection end of the pressure sensor 507. A movable support roller 509 is rotatably connected to the surface of the detection shaft 508. The movable support roller 509 overlaps with the lower surface of the synchronous belt body 4.

[0031] It should be noted that a controller is provided on the back of the protective shell 1. The controller is electrically connected to the pressure sensor 507 and the regulating motor 502 respectively, so that the tension of the synchronous belt body 4 can be monitored in real time by using the pressure sensor 507.

[0032] It is worth noting that by setting a tensioning mechanism 5 inside the synchronous belt protective shell 1, the movable support roller 509 on the surface of the detection shaft 508 can limit and support the surface of the synchronous belt body 4, and the pressure sensor 507 can detect the pressure on the surface of the movable support roller 509. When the tension of the synchronous belt body 4 is detected to decrease, the adjusting motor 502 can be started to drive the tensioning screw 503 to rotate, thereby driving the moving frame 505 to move upward inside the protective shell 1, and at the same time driving the tensioning wheel 506 to perform tensioning operation on the synchronous belt body 4, so as to achieve the purpose of real-time monitoring and adjustment of the synchronous belt tension.

[0033] Working principle: During the rotation of the synchronous belt, the movable support roller 509 on the surface of the detection shaft 508 contacts and rotates the bottom of the synchronous belt body 4. At the same time, the pressure sensor 507 detects the pressure on the detection shaft 508. When the pressure drops, it indicates that the tension of the synchronous belt surface is insufficient. The controller then starts the adjusting motor 502, which drives the tension screw 503 to rotate. The tension screw 503 drives the movable plate 504 to move upward, which in turn drives the limit block 510 to move. The limit block 510 drives the moving frame 505 to move, which in turn drives the tension wheel 506 to move upward to press and limit the synchronous belt body 4. This achieves automatic monitoring and tensioning of the synchronous belt tension.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
