Sprockets are widely used in mechanical transmission in chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.

[0003] In order to reduce the wear of the internal parts of the engine and achieve the purpose of fuel saving, a motorcycle sprocket (specifically refer to patent number: 200520051642.0) is presented, which is composed of a sprocket movable plate, a flange, a dust plate, and a screw. The sprocket movable plate is composed of sprocket outer teeth and inner ratchet helical teeth. A flange is provided at the lower end of the inner ratchet helical teeth. Grooves are provided at both ends of the flange. A spring is provided in the groove at one end of the flange. A wedge is provided at the upper end of the spring. A roller is provided in the groove at the other end of the flange. Dust plates are provided on both sides of the sprocket movable plate, and a screw is provided on the dust plates. The utility model has a simple structure and is easy to operate. It can reduce the driver's frequent operation behavior, reduce the wear of the internal parts of the engine, and achieve the purpose of fuel saving.

[0004] However, when the existing motorcycle sprocket passes through a muddy area, the mud will directly adhere to the outside of the motorcycle sprocket. After a period of driving, the mud will solidify on the motorcycle sprocket, causing continuous friction between the contact end of the motorcycle sprocket and the chain belt, causing foreign body wear. If this continues for a long time, not only the service life of the motorcycle sprocket and the chain belt will be reduced, but also the sensitivity of the motorcycle sprocket rotation will be reduced, thereby reducing the utilization rate. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that when the existing motorcycle sprocket passes through a muddy area, mud will directly adhere to the outer side of the motorcycle sprocket. After a period of driving, the mud will solidify on the motorcycle sprocket, causing continuous friction between the contact end of the motorcycle sprocket and the chain belt, resulting in foreign body wear. If this continues for a long time, not only the service life of the motorcycle sprocket and the chain belt will be reduced, but also the sensitivity of the motorcycle sprocket rotation will be reduced, thereby reducing the utilization rate. A motorcycle chain transmission component that can reduce foreign body wear is provided.

[0006] To achieve the above object, the utility model provides the following technical solution: a motorcycle chain transmission assembly capable of reducing foreign body wear, comprising:

[0007] Sprockets, used to transmit the rotational motion and power of the shaft;

[0008] A movable component is located outside the sprocket and is movably embedded on the sprocket;

[0009] A chain belt, located outside the sprocket and movably connected to the chain belt;

[0010] A docking hole is provided at the middle position of one end of the sprocket, a movable groove is provided on the outer side of the sprocket, and the movable groove is in an annular structure, and a plurality of groups of limiting grooves are evenly arranged on the side of the movable groove close to the docking hole, the movable component includes a movable part, and a locking tooth is provided on the side of the movable part away from the docking hole, and a limiting strip is provided on the side of the movable part away from the locking tooth, and elastic parts are provided at both ends of the limiting strip away from the locking tooth.

[0011] As a further solution of the utility model: the number of the plurality of groups of limit grooves is six, and the end surfaces of the six groups of limit grooves close to the movable grooves are all provided with movable holes.

[0012] As a further solution of the utility model: the elastic member and the limiting strip are both located inside the limiting groove, and both ends of the elastic member are respectively welded to the limiting strip and the end surface of the limiting groove close to the docking hole through welding blocks.

[0013] As a further solution of the utility model: the movable member is movably connected to the sprocket through a movable hole.

[0014] As a further solution of the present invention: the width of the movable hole is smaller than the width of the limiting groove and the limiting strip.

[0015] As a further solution of the utility model: a plurality of groups of tooth grooves are evenly arranged on the inner side of the chain belt, and the movable member is meshed and connected with the chain belt through the mutual cooperation of the latch teeth and the tooth grooves.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By providing the sprocket, movable assembly and chain belt, when in use, the movable part in direct contact with the chain belt is affected by the resistance pressure of the chain belt, so that the movable part generates resistance pressure on the elastic part inside the limiting groove, so that it is deformed by force and generates corresponding elastic potential energy. At the same time, the movable part is located inside the movable groove and close to the docking hole. When the movable part on the sprocket moves to its right position, it slowly separates from the chain belt and breaks the engagement. The movable part is affected by the elastic rebound force of the elastic part, which generates an outward pushing force on the movable part, thereby making the movable part slowly bounce a distance toward the outside of the movable groove. By utilizing this elastic force, mud stained on the sprocket is thrown out, avoiding mud contamination, thereby reducing foreign body wear to a certain extent, not only extending the service life of the motorcycle sprocket and chain belt, but also improving the sensitivity of the motorcycle sprocket rotation, thereby improving the utilization rate.

The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0024] See also Figures 1 to 3 In an embodiment of the utility model, a motorcycle chain transmission assembly capable of reducing foreign matter wear comprises:

[0025] Sprocket 1, used to transmit the rotational motion and power of the shaft;

[0026] The movable component 2 is located outside the sprocket 1 and is movably embedded on the sprocket 1;

[0027] The chain belt 3 is located outside the sprocket 1 and is movably connected to the chain belt 3;

[0028] A docking hole is provided at the middle position of one end of the sprocket 1, a movable groove 101 is provided on the outer side of the sprocket 1, and the movable groove 101 is annular in structure, and a plurality of groups of limiting grooves 102 are evenly provided on the side of the movable groove 101 close to the docking hole, the movable component 2 includes a movable part 201, and a latch tooth 202 is provided on the side of the movable part 201 away from the docking hole, and a limiting strip 203 is provided on the side of the movable part 201 away from the latch tooth 202, and elastic parts 103 are provided at both ends of the limiting strip 203 away from the latch tooth 202.

[0029] Please refer to Figure 2 and 3 The number of the plurality of groups of limiting grooves 102 is six, and the end surfaces of the six groups of limiting grooves 102 close to the movable groove 101 are all provided with movable holes.

[0030] Please refer to Figure 2 and 3 The elastic member 103 and the limiting strip 203 are both located inside the limiting groove 102, and both ends of the elastic member 103 are respectively welded to the limiting strip 203 and the end surface of the limiting groove 102 near the docking hole through welding blocks.

[0031] Please refer to Figure 2 and 3 The movable part 201 is movably connected to the sprocket 1 through the movable hole, so that the movable part 201 has a certain movable space. By utilizing the movable space, the movable part 201 can be elastically moved under force, so that the elastic force can be used to easily throw out the dirt contaminated on the outside.

[0032] Please refer to Figure 2 and 3 The width of the movable hole is smaller than the width of the limiting groove 102 and the limiting strip 203. The limiting groove 102 is used to firmly restrict the limiting strip 203 to move within the range.

[0033] Please refer to Figure 2 and 3 A plurality of groups of tooth grooves are evenly arranged on the inner side of the chain belt 3, and the movable member 201 is meshed and connected with the chain belt 3 through the mutual cooperation of the latch teeth 202 and the tooth grooves.

[0034] The working principle of the utility model is as follows: when in use, the movable part 201 which is in direct contact with the chain belt 3 is affected by the resistance pressure of the chain belt 3, so that the movable part 201 generates a resistance pressure on the elastic part 103 inside the limiting groove 102, so that it is deformed by the force and generates corresponding elastic potential energy. At the same time, the movable part 201 is located inside the movable groove 101 and toward the position close to the docking hole. When the movable part 201 on the sprocket 1 moves to its right position, it slowly separates from the chain belt 3 and disconnects the meshing, the movable part 201 is affected by the elastic rebound force of the elastic part 103, so that it generates an outward pushing force on the movable part 201, thereby making the movable part 201 slowly bounce a distance toward the outside of the movable groove 101. By utilizing this elastic force, the mud stained on the sprocket is thrown out, avoiding mud contamination, thereby reducing the wear of foreign matter to a certain extent, not only prolonging the service life of the motorcycle sprocket and chain belt, but also improving the sensitivity of the motorcycle sprocket rotation, thereby improving the utilization rate.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
