Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle gears, and particularly relates to a motorcycle gear with an anti-rust and noise reduction structure. Background Art

[0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Gears are toothed mechanical parts that can mesh with each other. The application of gears in transmission appeared very early. The principle of the gear cutting method and the successive emergence of special machine tools and tools for gear cutting using this principle have led to the increasing attention to the smooth operation of gears with the development of production.

[0003] Gears are also important components on motorcycles. However, during use, gears often generate relatively large noises during rotation. However, existing gears do not have the function of noise reduction. Therefore, a motorcycle gear with an anti-rust and noise reduction structure is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a motorcycle gear with an anti-rust and noise reduction structure to solve the problems raised in the above background art.

[0007] The housing mechanism includes a web. Teeth are fixedly connected to the outer surface of the web. A hub is arranged on the inner wall of the web. A shaft hole and a keyway are formed on the hub.

[0008] A further improvement of the technical solution of the utility model lies in that: a reinforcing plate is fixedly connected inside the web. Reinforcing ribs are fixedly connected to the surface of the reinforcing plate. One end of the reinforcing rib is fixedly connected inside the web. The reinforcing plate and the reinforcing ribs are connected to the inside of the web, thereby enhancing the support strength of the web.

[0009] A further improvement of the technical solution of the utility model lies in that: the noise reduction mechanism includes a nylon layer. The nylon layer is fixedly connected to the inside of the web on the outside. A rubber layer is arranged on the inner side of the nylon layer. A polyethylene layer is arranged on the inner side of the rubber layer. The rubber layer has good anti-slip and wear-resistant properties, thereby buffering the impact force generated during the operation of the gear.

[0010] A further improvement of the technical solution of this utility model lies in that: the polyethylene layer is fixedly connected to the reinforcing plate. Connecting grooves are provided on the nylon layer, the rubber layer and the polyethylene layer, and the connecting grooves are fixedly connected to the reinforcing ribs. The reinforcing ribs connect the nylon layer, the rubber layer and the polyethylene layer, thereby improving the tightness inside the gear.

[0011] A further improvement of the technical solution of this utility model lies in that: the oil storage mechanism includes an oil storage cotton, the oil storage cotton is arranged between the reinforcing plate and the polyethylene layer, a fixing groove is provided on the oil storage cotton, and the fixing groove is fixedly connected to the reinforcing rib. The reinforcing plate and the polyethylene layer fix the position of the oil storage cotton, thereby preventing the oil storage surface from moving.

[0012] A further improvement of the technical solution of this utility model lies in that: a transmission pipe is fixedly connected inside the oil storage cotton, the transmission pipe penetrates through the web plate, the tooth, the nylon layer, the rubber layer and the polyethylene layer, and an elastic sheet is fixedly connected to the inner wall of the transmission pipe. The anti-rust oil flows inside the transmission pipe, thereby preventing the anti-rust oil from leaking.

[0013] A further improvement of the technical solution of this utility model lies in that: one end of the elastic sheet is fixedly connected to a baffle, the baffle is hinged to the inner wall of the transmission pipe, and one end of the transmission pipe is threadedly connected to a sealing plug.

[0015] 1. This utility model provides a motorcycle gear with an anti-corrosion and noise reduction structure. The nylon layer has strong oil resistance, and the rubber layer has good anti-slip and wear-resistant properties, thereby buffering the impact generated during the operation of the gear. At the same time, the rubber layer can effectively reduce the propagation and influence of noise, thereby reducing the penetration and reflection of noise. The polyethylene layer is located outside the rubber layer, and the polyethylene layer has good corrosion resistance, thereby protecting the rubber layer and preventing the corrosion from affecting the noise reduction function of the rubber layer, thus achieving the purpose of improving the noise reduction effect of the gear.

[0016] 2. This utility model provides a motorcycle gear with an anti-corrosion and noise reduction structure. Push the anti-rust oil into one end of the transmission pipe, the baffle is forced to open inward, and the anti-rust oil can enter the oil storage cotton through the transmission pipe.

Specific embodiments

[0023] The following further describes the present utility model in detail with reference to the embodiments:

[0024] Embodiment 1

[0025] As Figures 1-5 shown, the present utility model provides a motorcycle gear with an anti-corrosion and noise reduction structure, including an outer shell mechanism 1. A noise reduction mechanism 2 is arranged inside the outer shell mechanism 1, and an oil storage mechanism 3 is arranged inside the outer shell mechanism 1. The outer shell mechanism 1 includes a web 11. Teeth 12 are fixedly connected to the outer surface of the web 11. A hub 13 is arranged on the inner wall of the web 11. An axle hole 14 and a keyway 15 are formed in the hub 13. A reinforcing plate 16 is fixedly connected inside the web 11. Reinforcing ribs 17 are fixedly connected to the surface of the reinforcing plate 16. One end of the reinforcing rib 17 is fixedly connected inside the web 11;

[0026] Specifically, the teeth 12 and the hub 13 are the main bodies of the gear. The hub 13 is the main load-bearing part of the gear and is usually made of cast steel or forged steel. The connecting parts of the shaft hole 14 and the keyway 15 are used to connect the bearing and the shaft and are usually made of cast iron or cast steel. The web 11 is a key part of the gear. The teeth 12 and the meshing directly affect the transmission efficiency and smoothness of the gear. The tooth profile of the teeth 12 is usually composed of parameters such as the addendum height, the dedendum height, the backlash, and the addendum circle radius. Different shapes of the teeth 12 are suitable for different transmission occasions. Meshing is the key link of gear transmission, and its meshing quality determines the smoothness and service life of gear transmission. The reinforcing plate 16 and the reinforcing rib 17 are connected inside the web 11, thereby strengthening the supporting strength of the web 11. At the same time, the reinforcing rib 17 connects and supports the noise reduction mechanism 2 and the oil storage mechanism 3, thereby improving the tightness inside the gear and prolonging the service life of the gear.

[0027] Embodiment 2

[0028] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the noise reduction mechanism 2 includes a nylon layer 21. The outer side of the nylon layer 21 is fixedly connected inside the web 11. A rubber layer 22 is arranged on the inner side of the nylon layer 21. A polyethylene layer 23 is arranged on the inner side of the rubber layer 22. The polyethylene layer 23 is fixedly connected to the reinforcing plate 16. Connecting grooves 24 are formed on the nylon layer 21, the rubber layer 22 and the polyethylene layer 23, and the connecting grooves 24 are fixedly connected to the reinforcing rib 17.

[0029] Specifically, the nylon layer 21 has strong oil resistance. The rubber layer 22 has good anti-slip performance and wear resistance, so as to buffer the impact force generated during the operation of the gear. At the same time, the rubber layer 22 can effectively reduce the propagation and influence of noise, thereby reducing the penetration and reflection of noise. The polyethylene layer 23 is located outside the rubber layer 22. The polyethylene layer 23 has good corrosion resistance, so as to protect the rubber layer 22 and prevent the noise reduction function of the rubber layer from being affected by corrosion.

[0030] Embodiment 3

[0031] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the oil storage mechanism 3 includes an oil storage cotton 31. The oil storage cotton 31 is arranged between the reinforcing plate 16 and the polyethylene layer 23. A fixing groove 32 is formed in the oil storage cotton 31. The fixing groove 32 is fixedly connected to the reinforcing rib 17. A transmission pipe 33 is fixedly connected inside the oil storage cotton 31. The transmission pipe 33 penetrates through the web plate 11, the teeth 12, the nylon layer 21, the rubber layer 22 and the polyethylene layer 23. An elastic piece 34 is fixedly connected to the inner wall of the transmission pipe 33. One end of the elastic piece 34 is fixedly connected to a baffle 35. The baffle 35 is hinged to the inner wall of the transmission pipe 33. One end of the transmission pipe 33 is threadedly connected with a sealing plug 36;

[0032] Specifically, when the anti-rust oil in the oil storage cotton 31 is lacking, the sealing plug 36 is unscrewed. Then, the anti-rust oil is pushed into one end of the transmission pipe 33. The baffle 35 is forced to open inward. The anti-rust oil can then enter the oil storage cotton 31 through the transmission pipe 33. After the oil storage cotton 31 is filled with anti-rust oil, the pushing force on the baffle 35 disappears. The elastic force of the elastic piece 34 itself drives the baffle 35 to return to its original position, thus avoiding the phenomenon of backflow of the anti-rust oil. Then, the sealing plug 36 is screwed into the transmission pipe 33 to seal the transmission pipe 33, thus avoiding the phenomenon of leakage of the anti-rust oil.

[0033] Next, the working principle of the motorcycle gear of the anti-corrosion and noise reduction structure will be specifically described.

[0034] As Figures 1-5 shown, the teeth 12 and the hub 13 are the main bodies of the gear. The shaft hole 14 and the keyway 15 are the connecting parts, used to connect the bearing and the shaft. The teeth 12 and the meshing directly affect the transmission efficiency and stability of the gear. The reinforcing plate 16 and the reinforcing rib 17 connect the inside of the web plate 11, thereby strengthening the support strength of the web plate 11. At the same time, the reinforcing rib 17 connects and supports the noise reduction mechanism 2 and the oil storage mechanism 3, thereby improving the tightness inside the gear. The nylon layer 21 has strong oil resistance. The rubber layer 22 has good anti-slip performance and wear resistance. The rubber layer 22 can effectively reduce the propagation and influence of noise. The polyethylene layer 23 is located outside the rubber layer 22 to protect the rubber layer 22. When the anti-rust oil in the oil storage cotton 31 is lacking, the anti-rust oil is pushed into one end of the transmission pipe 33. The baffle 35 is forced to open inward. The anti-rust oil can then enter the oil storage cotton 31 through the transmission pipe 33. After the oil storage cotton 31 is filled with anti-rust oil, the pushing force on the baffle 35 disappears. The elastic force of the elastic piece 34 itself drives the baffle 35 to return to its original position. Then, the sealing plug 36 is screwed into the transmission pipe 33 to seal the transmission pipe 33, thus avoiding the phenomenon of leakage of the anti-rust oil.

[0035] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
