Description

Technical Field

[0001] The utility model relates to the technical field of sprockets, in particular to a detachable sprocket. Background Art

[0002] A sprocket is a mechanical component used to cooperate with a chain for transmission. It is mainly used in industrial equipment, such as scrapers and bucket elevators, which all use sprocket transmission. During normal use, the teeth on the sprocket will wear and deform during continuous operation, and the sprocket needs to be replaced. Usually, due to the one-piece molding characteristics of the sprocket, it is necessary to remove the coupling connected to it from the bearing during the disassembly process, and then use a hammer to knock the sprocket along the direction of the coupling. This method of removing additional parts and brute force makes the disassembly work time-consuming and labor-intensive, and the overall maintenance efficiency is low.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a detachable sprocket.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The detachable sprocket comprises a sprocket body, which is equipped with a fixed sleeve installed on the shaft; the sprocket body is divided into two groups of half wheels detachably connected to the fixed sleeve.

[0008] Furthermore, the sprocket body is evenly divided from the tooth roots.

[0009] Furthermore, a mounting ring plate is provided on the fixed shaft sleeve, and an inner connecting ring plate which is synchronously and evenly divided with the sprocket body is provided on the inner side of the sprocket body, and the mounting ring plate and the inner connecting ring plate are connected and fixed by a through-bolt group.

[0010] Furthermore, a first snap-in socket adapted to engage with the mounting ring plate is formed between the half wheel and the inner ring plate.

[0011] Furthermore, a limiting ring is provided on the fixed sleeve, and a clamping ring groove for the inner ring plate to be clamped is formed between the limiting ring and the mounting ring plate, and a second clamping socket adapted to be clamped with the limiting ring is opened on the inner side of the inner ring plate.

[0012] Furthermore, a first connecting plate is provided on the fixed sleeve, and a second connecting plate is provided on the half wheel, and the first connecting plate and the second connecting plate are fixed by a bolt group.

[0013] Compared with the prior art, the beneficial effect of this solution is that the utility model arranges the sprocket body into two groups of half wheels that can be separated and a fixed shaft sleeve for assembling the half wheels, so that when the sprocket body needs to be removed and replaced, the half wheels can be directly removed from the fixed shaft sleeve independently, thereby eliminating the need to remove the shaft rod and knock it apart, and improving replacement efficiency.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, the first embodiment of the present invention includes a sprocket body 1, which is equipped with a fixed sleeve 2 installed on the shaft; the sprocket body 1 is divided into two groups of half wheels 21 detachably connected to the fixed sleeve 2, and the fixed sleeve 2 is installed on the shaft by interference fit. When the sprocket body 1 needs to be installed, the half wheels 21 formed by dividing the sprocket body 1 into two halves are aligned from both sides of the fixed sleeve 2 and then connected and fixed to the fixed sleeve 2 to achieve a quick installation effect. For removal, the half wheels 21 on a single side can be removed independently as needed, thereby improving replacement efficiency.

[0027] More specifically, the sprocket body 1 is evenly divided from the tooth roots, thereby avoiding damage to the integrity of the gear teeth and reducing their impact on the chain transmission.

[0028] More specifically, a mounting ring plate 22 is provided on the fixed shaft sleeve 2, and an inner connecting ring plate 23 which is synchronously and evenly divided with the sprocket body 1 is provided on the inner side of the sprocket body 1. The mounting ring plate 22 and the inner connecting ring plate 23 are connected and fixed by a through-bolt group 24. The half wheel 21 is aligned with the bolt group 24 through the inner connecting ring plate 23 inside it, and a plurality of corresponding through holes of the same size are provided thereon, and then the bolt group 24 is passed through to form a fixation, thereby improving the convenience of assembly and disassembly.

[0029] More specifically, the thickness of the inner ring plate 23 is less than the thickness of the half wheel 21, and a first bayonet 3 is formed between the half wheel 21 and the inner ring plate 23 to adapt to the mounting ring plate 22, ensuring that no excessive concave and convex surfaces are formed between the half wheel 21 and the mounting ring plate 22 when spliced, thereby maintaining the overall balance.

[0030] More specifically, a limiting ring 31 is further provided on the fixed sleeve 2, and a snap ring groove 32 for the inner ring plate 23 to be snapped in is formed between the limiting ring 31 and the mounting ring plate 22, and a second snap ring 33 which is adapted to be snapped in with the limiting ring 31 is provided on the inner side of the inner ring plate 23. By setting the limiting ring 31, it is ensured that the inner ring plate 23 will not slide along the axial direction of the fixed sleeve 2, thereby limiting it in this direction. When the bolt group 24 becomes loose, it will not cause excessive relative movement between the half wheel 21 and the fixed sleeve 2, thereby ensuring that the overall structure is more stable.

[0031] like Figure 8 、 9 As shown, this is a second embodiment of the present invention, a first connecting plate 4 is provided on the fixed shaft sleeve 2, and a second connecting plate 41 is provided on the half wheel 21, and the first connecting plate 4 and the second connecting plate 41 are fixed by a bolt group 24. In this embodiment, the half wheel 21 is matched with the first connecting plate 4 on the fixed shaft sleeve 2 through the second connecting plates 41 on both sides, and then connected with the fixing bolt group 24 to form a connection. This connection method is more convenient, but its stability is slightly weaker than the connection method of the first embodiment. Therefore, its usage scenario is on equipment with lower transmission strength requirements. At the same time, the connection methods in the two embodiments can have the effect of independently removing a group of half wheels 21 for replacement, and then when only a single group of half wheels 21 needs to be removed, the other group of half wheels 21 can still support the chain, so that the disassembly and assembly work can avoid the impact on other structures to the greatest extent.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
