Description

Technical Field

[0001] The utility model relates to the technical field of sprocket wheel edges, in particular to a sprocket wheel edge with a stable structure. Background Art

[0002] A sprocket is a wheel with cog-shaped sprocket teeth that meshes with a precisely pitched block on a link chain or cable. Sprockets are widely used in mechanical transmission in industries such as chemical industry, textile machinery, escalators, wood processing, parking garages, agricultural machinery, food processing, instrumentation, and petroleum.

[0003] The currently published patent: CN220286352U discloses a sprocket wheel edge with auxiliary braking. The sprocket wheel edge with auxiliary braking is provided with a connecting assembly. When the brake hub and the single-row shaft need to be installed, the personnel dock the brake hub with the single-row shaft so that the bolt holes are aligned and the brake hub is pushed. At this time, the surface of the ring will resist the resistance surface of the block, so that the block enters the slide groove of the annular groove, and the ring enters the annular groove at the same time. When the positions of the groove and the block coincide, the block enters the groove under the action of the spring, so that the groove limits the block, and then the brake hub and the single-row shaft are stable. At this time, the personnel can tighten the bolts without the need to hold the brake hub all the time.

[0004] Based on the above search, it was found that the above patent has the following problems when used: during the installation of the brake hub, the sprocket wheel edge limits the block through the slot, thereby stabilizing the brake hub and the single-row shaft. However, with this fixing method, the block is small in size, and the brake hub and the single-row shaft are fixed with a smaller block. Since the smaller block has a smaller compressive strength, the stability of the installation of the brake hub and the single-row shaft is reduced, affecting the stability of the sprocket during rotation. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a sprocket wheel edge with a stable structure, which can solve the problem that the size of the clamping block is small, the stability of fixing the brake hub and the single-row shaft by the smaller clamping block is low, and the stability of the sprocket during rotation is affected.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sprocket wheel edge with a stable structure, comprising a sprocket body and a fixing mechanism; the sprocket body is fixedly connected with a single-row shaft, and a brake hub is arranged on the surface of the single-row shaft; the fixing mechanism comprises a circular ring, two fixed clamping blocks, a spring and two limit clamping blocks, the circular ring is fixedly connected to the inner wall of the brake hub, and two fixed clamping grooves are arranged on the surface of the circular ring, and the two fixed clamping grooves are symmetrically arranged, and the two fixed clamping blocks are both slidably connected to the inside of the single-row shaft, and the opposite ends of the two fixed clamping blocks are both inclined surfaces, and the opposite ends of the two fixed clamping blocks are respectively slidably clamped in the inside of the two fixed clamping grooves, and the spring is fixedly connected to the opposite ends of the two fixed clamping blocks.

[0007] Preferably, a connecting plate is installed at one end of the single-row shaft close to the sprocket body, and a shoe-type brake assembly is arranged on the connecting plate.

[0008] Preferably, a connection assembly is installed on the surface of the single-row shaft, and the surface of the connection assembly is circular and evenly provided with six bolt notches.

[0009] Preferably, the rear side of the brake hub is circular and evenly mounted with six bolts.

[0010] Preferably, the surfaces of the two fixed card blocks are provided with limit card slots, and the two limit card blocks are slidably connected inside the two limit card slots respectively.

[0011] Preferably, the two limit blocks are fixedly connected to the inner wall of the single-row shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The sprocket wheel edge with a stable structure fixes the brake hub and the single-row shaft by the clamping action between two fixed clamping blocks and two fixed clamping grooves. Since the two fixed clamping blocks are larger in volume, the compressive strength of the two fixed clamping blocks is also greater. Therefore, the stability of the installation between the brake hub and the single-row shaft can be improved, thereby ensuring the stability of the sprocket during rotation.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] See also Figure 1-4The utility model provides a technical solution: a sprocket wheel edge with a stable structure, including a sprocket body 1 and a fixing mechanism, the sprocket body 1 is fixedly connected with a single-row shaft 4, a connecting plate 2 is installed at one end of the single-row shaft 4 close to the sprocket body 1, a shoe-type brake assembly 3 is arranged on the connecting plate 2, a dry wheel edge lubrication device is installed inside the connecting plate 2, a point-to-point solid lubrication method is adopted, a uniform and continuous metal film is formed by continuously applying a lubricant on the wheel rim, when the film is reduced, the lubricating block will lubricate the wheel rim contacting the wheel again, over and over again, this lubrication method is carried out in real time, the adhesion between the lubricating medium and the wheel rail is strong, and no splashing is generated.

[0025] A connecting assembly 5 is installed on the surface of the single-row shaft 4, and six bolt notches 6 are evenly arranged on the surface of the connecting assembly 5 in a circular shape. A brake hub 7 is provided on the surface of the single-row shaft 4, and six bolts 8 are evenly arranged on the rear side of the brake hub 7 in a circular shape.

[0026] The fixing mechanism includes a circular ring 9, two fixed blocks 11, a spring 13 and two limit blocks 15. The circular ring 9 is fixedly connected to the inner wall of the brake hub 7. Two fixed slots 10 are provided on the surface of the circular ring 9. The two fixed slots 10 are symmetrically arranged. The two fixed blocks 11 are both slidably connected to the inside of the single-row shaft 4. The opposite ends of the two fixed blocks 11 are both inclined surfaces 12. The opposite ends of the two fixed blocks 11 are respectively slidably connected to the inside of the two fixed slots 10. The spring 13 is fixedly connected to the opposite ends of the two fixed blocks 11.

[0027] The staff member picks up the brake hub 7 and puts it on the surface of the single-row shaft 4, rotates the brake hub 7 and drives the ring 9 to rotate, and rotates the two fixed grooves 10 on the surface of the ring 9 to a position on the same horizontal line as the two fixed blocks 11, and then the staff member slides the brake hub 7 forward, and the brake hub 7 slides forward and drives the ring 9 to slide forward to squeeze the inclined surfaces 12 of the two fixed blocks 11. At this time, the two fixed blocks 11 are squeezed by the ring 9 and slide relatively to squeeze the spring 13. The spring 13 gives the two fixed blocks 11 a reverse elastic force. When the two fixed grooves 10 slide to the position where they are aligned with the two fixed blocks 11, the spring 13 can release the elastic force to push the two fixed blocks 11 to slide on the opposite sides and get stuck in the two fixed slots 10. At this time, the staff can use a wrench to rotate the six bolts 8 to connect with the connecting assembly 5. This fixing method is to fix the brake hub 7 and the single-row shaft 4 to the clamping action between the two fixed blocks 11 and the two fixed slots 10. Since the volume of the two fixed blocks 11 is large, the compressive strength of the two fixed blocks 11 is also greater. Therefore, the stability of the installation between the brake hub 7 and the single-row shaft 4 can be improved, thereby ensuring the stability of the sprocket during rotation.

[0028] The surfaces of the two fixed blocks 11 are provided with limit slots 14 , and the two limit blocks 15 are slidably connected inside the two limit slots 14 , respectively. The two limit blocks 15 are fixedly connected to the inner wall of the single-row shaft 4 .

[0029] When the two fixed blocks 11 slide inside the single-row shaft 4 , the two fixed blocks 11 are limited by the connection between the two limiting blocks 15 and the two limiting slots 14 , thereby preventing the two fixed blocks 11 from escaping from the single-row shaft 4 .

[0030] Working principle: on the sprocket wheel edge with a stable structure, the staff slides the brake hub 7 forward and drives the ring 9 to slide forward to squeeze the inclined surfaces 12 of the two fixed blocks 11. At this time, the two fixed blocks 11 are squeezed by the ring 9 and slide relatively to squeeze the spring 13. The spring 13 gives the two fixed blocks 11 a reverse elastic force. When the two fixed slots 10 slide to the position of the two fixed slots 11, the spring 13 can release the elastic force to push the two fixed blocks 11 to slide in the opposite sides and get stuck in the inside of the two fixed slots 10. The brake hub 7 and the single-row shaft 4 are fixedly installed through the clamping action between the two fixed blocks 11 and the two fixed slots 10. In the process of the two fixed blocks 11 sliding inside the single-row shaft 4, the two fixed blocks 11 are limited by the connection between the two limiting blocks 15 and the two limiting slots 14, which can prevent the two fixed blocks 11 from escaping from the inside of the single-row shaft 4.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
