Description

Technical Field

[0001] This utility model relates to the field of drive chain guiding technology, and in particular to a drive chain rolling guiding mechanism. Background Technology

[0002] A drive chain is a type of chain. A chain is a flexible transmission component composed of metal links or rings. It is mainly used for mechanical power transmission, traction, or fixation. It is a basic component in mechanical engineering. Typically, a drive chain drives a driven sprocket to rotate.

[0003] A search revealed that CN218522997U discloses a drive chain rolling guide mechanism, including a driving sprocket and a driven sprocket. The driving sprocket and the driven sprocket are connected and driven by a drive chain. A bracket is provided between the driving sprocket and the driven sprocket to support the drive chain. However, its roller bearings only serve a supporting and guiding function, and the position of the roller bearings cannot be adjusted. Therefore, it cannot be adapted to different sizes of sprockets and drive chains, which limits its use. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drive chain rolling guide mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drive chain rolling guide mechanism includes a driving sprocket and a driven sprocket, which are connected by a drive chain body. A bracket is provided between the driving sprocket and the driven sprocket. Two sliding grooves are formed on one side of the bracket, and a slider is slidably connected in each of the two sliding grooves. A first guide plate is fixedly connected to one side of the slider, and a second guide plate is fixedly connected to one side of the bracket. Mounting grooves are formed on opposite sides of the first and second guide plates. Multiple guide rollers supporting the drive chain body are rotatably connected in the mounting grooves via bearings, and the guide rollers are adapted to the drive chain body for rolling connection. A single-ended stud is rotatably connected to one side of the bracket via a bearing. An annular groove is formed on the outer side of the single-ended stud, and a rotating ring is rotatably connected in the annular groove. A top rod is fixedly connected to the outer side of the rotating ring, and a top block is fixedly connected to one end of the top rod.

[0007] As a further embodiment of this invention, the outer thread of the single-ended stud is connected to a locking nut for locking the swivel ring.

[0008] As a further embodiment of this utility model, the first guide plate, the first baffle, and the mounting groove on the first guide plate are all arc-shaped structures.

[0009] As a further embodiment of this invention, the guide rollers located within the first guide plate are evenly distributed along the arc direction of the mounting groove.

[0010] As a further embodiment of this utility model, the top block is circular, and all the top blocks are located between the first guide plate and the second guide plate.

[0011] As a further embodiment of this utility model, a first baffle and a second baffle are respectively fixedly connected to one side of the first guide plate and the second guide plate at the positions on both sides of the mounting groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the drive chain is supported and guided by the guide roller, which converts sliding friction into rolling friction, effectively reducing the frictional loss of the drive chain and improving its service life. Furthermore, the rotating ring drives the top rod to rotate, which in turn drives the top block to rotate. The top block pushes the first guide plate to move along the slide groove via the slider, thereby changing the distance between the two guide plates to accommodate sprockets and chains of different sizes. At the same time, if the drive chain becomes slack, the first guide plate moves to lift and tighten the drive chain, eliminating the need for an additional tensioning mechanism to adjust the tension of the drive chain and saving costs.

[0014] 2. In this utility model, by setting the locking nut, the rotating ring can be locked and fixed by tightening the locking nut, thereby fixing the rotation angle of the top rod and the top block, so that the top block can stably lift the first guide plate. Attached Figure Description

[0019] 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. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0020] Reference Figures 1-3 A drive chain rolling guide mechanism includes a drive sprocket 1 and a driven sprocket 6, which are connected by a drive chain body 2 and have a tolerance grade of H7 / d9.

[0021] A bracket 4 is provided between the driving sprocket 1 and the driven sprocket 6. Two sliding grooves 3 are opened on one side of the bracket 4. A slider 14 is slidably connected in each of the two sliding grooves 3. A first guide plate 7 is welded to one side of the slider 14. A second guide plate 9 is fixed to one side of the bracket 4 by bolts. Mounting grooves 12 are opened on the opposite sides of the first guide plate 7 and the second guide plate 9. Multiple guide rollers 11 that support the drive chain body 2 are rotatably connected in the mounting grooves 12 by bearings. The guide rollers 11 are adapted to the drive chain body 2 and are rolled. The drive chain body 2 is supported and guided by the guide rollers 11 in the first guide plate 7 and the second guide plate 9, which converts sliding friction into rolling friction. There is no relative movement between the chain plate and the guide rollers 11 in the drive chain, which can effectively reduce the friction loss of the drive chain and improve the service life of the drive chain.

[0022] In this utility model, a single-headed stud 8 is rotatably connected to one side of the bracket 4 via a bearing. An annular groove 15 is provided on the outer side of the single-headed stud 8. A rotating ring 16 is rotatably connected inside the annular groove 15. A top rod 17 is welded to the outer side of the rotating ring 16. A top block 18 is welded to one end of the top rod 17.

[0023] When dealing with larger sprockets and drive chains, the guide roller 11 inside the second guide plate 9 is first made to contact and support the drive chain below. Then, the rotating ring 16 is manually rotated. The rotating ring 16 drives the top rod 17 to rotate, and the top rod 17 drives the top block 18 to rotate. The top block 18 pushes the first guide plate 7 to move upward along the slide groove 3 through the slider 14, thereby changing the distance between the first guide plate 7 and the second guide plate 9, so that the guide roller 11 on the first guide plate 7 contacts and supports the drive chain above, thus adapting to sprockets and chains of different sizes.

[0024] In this invention, when the drive chain becomes loose, the top block 18 can be pushed upward by rotating the rotating ring 16, so that the guide tube 11 on the first guide plate 7 can support and tighten the drive chain. No additional tensioning mechanism is needed to adjust the tightness of the drive chain, thus saving costs.

[0025] In this utility model, the outer thread of the single-headed stud 8 is connected to a locking nut 13 for locking the rotating ring 16. The locking nut 13 is used to lock and fix the rotating ring 16, thereby fixing the rotation angle of the top block 18. The first guide plate 7, the first baffle 5 and the mounting groove 12 on the first guide plate 7 are all arc-shaped structures. The guide rollers 11 located in the first guide plate 7 are evenly distributed along the arc direction of the mounting groove 12. The top block 18 is circular. The top blocks 18 are all located between the first guide plate 7 and the second guide plate 9 and are in contact with the first guide plate 7. The arc surface of the circular top block 18 can better match the first guide plate 7.

[0026] In this utility model, a first baffle 5 and a second baffle 10 are welded to one side of the first guide plate 7 and the second guide plate 9 on both sides of the mounting groove 12, respectively. The first baffle 5 and the second baffle 10 can block the drive chain body 2 and prevent the drive chain body 2 from deviating.

[0027] Working principle: During use, the drive chain body 2 is supported and guided by the guide rollers 11 in the first guide plate 7 and the second guide plate 9, which converts sliding friction into rolling friction. There is no relative movement between the chain plate and the guide rollers 11 in the drive chain, which can effectively reduce the frictional loss of the drive chain and improve the service life of the drive chain.

[0028] When dealing with larger sprockets and drive chains, the guide roller 11 inside the second guide plate 9 is first brought into contact with and supported by the drive chain below. Then, the locking nut 13 is loosened, and the rotating ring 16 is manually rotated. The rotating ring 16 drives the top rod 17 to rotate, and the top rod 17 drives the top block 18 to rotate. The top block 18 pushes the first guide plate 7 to move upward along the slide groove 3 through the slider 14, thereby changing the distance between the first guide plate 7 and the second guide plate 9, so that the guide roller 11 on the first guide plate 7 comes into contact with and supports the drive chain above. Then, the locking nut 13 is tightened to fix the top block 18, thereby adapting to sprockets and chains of different sizes.

[0029] When the drive chain becomes slack, the top block 18 can be pushed upward by rotating the swivel ring 16, so that the guide tube 11 on the first guide plate 7 can support and tighten the drive chain. No additional tensioning mechanism is needed to adjust the tightness of the drive chain, thus saving costs.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that there are two annular grooves 15, rotating rings 16, top rods 17, and top blocks 18, which symmetrically limit and support the first guide plate 7 from both sides, thereby making the first guide plate 7 more balanced.

[0032] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
