Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle sprockets, in particular to a high-precision motorcycle sprocket with shock-absorbing and noise-reducing effects. Background Art

[0002] A sprocket is a motorcycle sprocket with a vibration-absorbing and noise-reducing effect. It is a wheel with cog-type sprocket teeth, which is used to mesh with blocks with accurate pitch on the link chain or cable. 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, and are also used in transportation tools such as motorcycles.

[0003] However, some existing motorcycle sprockets require manual application of lubricating oil on the chain and tooth positions, which is inconvenient to use. At the same time, manual application of lubricating oil leads to uneven application and different amounts of lubricating oil, which seriously affects the use effect. At the same time, the amount of lubricating oil is increased, which increases the use cost. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that some existing motorcycle sprockets need to be manually applied with lubricating oil on the chain and the tooth positions, which is inconvenient to use.

At the same time, the amount of lubricating oil used is increased, which increases the cost of use. A high-precision motorcycle sprocket with shock-absorbing and noise-reducing effects is provided.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision motorcycle sprocket with shock-absorbing and noise-reducing effects, comprising a sprocket part, a mounting hole is provided at the middle position inside the sprocket part, a latch tooth is provided outside the sprocket part, a chain is provided outside the latch tooth, a lubrication assembly is provided on one side of the sprocket part close to the latch tooth, the lubrication assembly comprises an oil storage cavity, an oil inlet pipe is provided at the top end inside the oil storage cavity, a rotary valve is provided inside the oil inlet pipe, a fixing frame is provided at the top of the fixing frame, an elastic member is provided at the top of the elastic member, and a blocking ball is provided at the top of the elastic member.

[0006] As a further solution of the utility model: the inner wall of the mounting hole is provided with a plurality of groups of limiting teeth.

[0007] As a further solution of the utility model: the sprocket and the clamping teeth are both made of "alloy steel".

When the lubricating oil attached to the outside of the device is less, the adjusting nut is rotated to drive the rotary valve to rotate, the oil inlet pipe is opened, and the lubricating oil in the oil storage chamber flows into the oil inlet pipe. When the device is running, the chain pushes the blocking ball inward to open the oil inlet pipe, so that the lubricating oil flows out to adhere to the chain surface for lubrication. At the same time, when the chain is no longer resisting the blocking ball, the oil inlet pipe is blocked again by the elastic part to reduce the outflow of the lubricating oil. The device is easy to use and has a simple structure. Through the provided lubrication component, the device can be lubricated with oil, and it is automatically sealed and opened, which saves the amount of lubricating oil used, and the lubricating oil reduces the generation of noise.
