Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a gear which is easy to disassemble. Background Art

[0002] Gears are mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. Gears can be divided into gear teeth, tooth grooves, end faces, normal faces, tooth top circles, tooth root circles, base circles, pitch circles, etc. The steels commonly used to manufacture gears are quenched and tempered steel, hardened steel, carburized and hardened steel, and nitrided steel.

[0003] At present, in order to facilitate transmission, gears are used for transmission. However, some existing gears are mostly installed on rotating shafts. When installed on the rotating shafts, they are mostly installed by welding or socketing. However, such installation is easy to cause the gears to be damaged in the later stage, which makes it inconvenient to disassemble, resulting in slow disassembly speed and reduced work efficiency of the staff. For this reason, we propose gears that are easy to disassemble. Utility Model Content

[0004] The purpose of the utility model is to provide a gear that is easy to disassemble, which has the advantage of being easy to disassemble, and solves the problem that some existing gears are mostly installed on rotating shafts. When installed on the rotating shaft, they are mostly installed by welding or socketing. However, such installation is prone to damage to the gear in the later stage, which makes it difficult to disassemble, thereby causing a slow disassembly speed and reducing the work efficiency of the staff.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gear that is easy to disassemble, comprising a left tooth body and a right tooth body, wherein the middle ends of the inner surfaces of the left tooth body and the right tooth body are respectively provided with positioning blocks, the front and rear sides of the left tooth body and the right tooth body are respectively provided with a second annular groove and a first annular groove, the inner surfaces of the middle ends of the left tooth body and the right tooth body are respectively provided with through holes, the outer surfaces of the left tooth body and the right tooth body are respectively provided with positioning slots distributed at equal angles, the inner sides of the positioning slots are provided with positioning blocks whose inner surfaces are provided with clamping slot holes, the inner sides of the second annular groove and the first annular groove are respectively provided with a second connecting ring and a first connecting ring, the front side of the second connecting ring and the rear side of the first connecting ring are respectively provided with a plurality of second clamping blocks and first clamping blocks distributed at equal angles, the left and right ends of the second connecting ring are respectively provided with threaded holes, the left and right ends of the first connecting ring are respectively provided with countersunk holes, and the inner sides of the countersunk holes are provided with connecting bolts.

[0006] Preferably, there are multiple positioning slots, and the front and rear sides of one end of the positioning slot are respectively connected to the second annular groove and the first annular groove.

[0007] Preferably, the number of the second clamping blocks is the same as that of the first clamping blocks, and both the second clamping blocks and the first clamping blocks are adapted to the positioning slots.

[0008] Preferably, the second clamping block and the first clamping block are both rectangular structures, and the depth of the second clamping block and the first clamping block is less than half of the depth of the positioning slot.

[0009] Preferably, the inner diameter of the through hole is larger than the outer diameter of the connecting bolt, and the through hole corresponds to the threaded hole and the countersunk hole one by one.

[0010] Preferably, the connecting bolt passes through the through hole, and the rear end of the connecting bolt is threadedly connected to the threaded hole.

[0011] Preferably, gear teeth are provided on the top of the positioning plug, and the distribution angle of the gear teeth is consistent with the positioning slot.

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

[0013] 1. The utility model uses a hexagonal wrench to unscrew the connecting bolt from the threaded hole, and makes it withdraw from the through hole and the countersunk hole in turn, and then remove the connecting bolt. Then, the first connecting ring and the second connecting ring can be driven to move outward, and the first clamping block and the second clamping block can be withdrawn from the clamping slot hole. Then, the left tooth body and the right tooth body can be moved outward and withdrawn from the surface of the rotating shaft. At the same time, the positioning clamping block can be withdrawn from the positioning groove on the surface of the rotating shaft, thereby realizing the rapid disassembly of the gear.

[0014] 2. The utility model sets the gear teeth and cooperates with the positioning slot. When the first connecting ring and the second connecting ring move outward and the first clamping block and the second clamping block exit the clamping slot, the gear teeth can drive the positioning plug to exit the corresponding positioning slot, thereby facilitating the staff to quickly replace the damaged gear teeth. The utility model has a simple structure, is easy to use, and improves the work efficiency of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
