[0002] The chain is one of the important transmission components of a motorcycle. It is generally a metal link or ring, mostly used for mechanical transmission and traction. It can transmit the traction force of the motorcycle engine to the wheels, thereby realizing the driving action of the motorcycle. In order to ensure the stability and durability of the chain, the chain is generally lubricated and maintained regularly. Currently, this operation is performed by applying lubricating oil or grease directly to the chain.

[0003] The gap between the inner link plate and the ball bearing of the existing chain is small, and there is no lubrication guide structure. As a result, the applied lubricating oil or grease can only lubricate the surface of the chain and cannot enter the friction area between the inner link plate and the ball bearing, resulting in poor lubrication effect and low practicality.

[0004] The disclosed embodiment relates to an inner link plate structure of a chain, which has an inner chain assembly. Through the lubrication groove opened on the inner link plate toward the ball roller, the applied lubricating oil or grease can be effectively guided to the contact part between the inner link plate and the ball roller, and the connection part between the ball roller and the connecting pin rod can also be lubricated, thereby reducing friction loss during use. The design of different depths of the outer and inner ends of the lubrication groove also enables more lubricating oil or grease to be stored inside the lubrication groove for use. At the same time, the design of the blocking roller can also reduce the leakage of lubricating oil and grease, and can maintain the lubrication state for a long time, with extremely high flexibility, stability and practicality.

[0008] In at least some embodiments, a weight-reducing groove is provided in the middle portion of the inner link plate.

[0009] In at least some embodiments, the inner link plates and the outer link plates are made of high-strength, wear-resistant materials.

[0010] In at least some embodiments, the contact portion between the outer chain component and the inner chain component is provided with a graphite coating.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Through the lubrication groove opened on the inner link plate toward the ball side, the applied lubricating oil or grease can be effectively guided to the contact part between the inner link plate and the ball, and can also lubricate the connection part between the ball and the connecting pin, thereby reducing friction loss during use. The design of different depths at the outer and inner ends of the lubrication groove also enables more lubricating oil or grease to be stored inside the lubrication groove for use.

[0021] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0022] As attached Figure 1 To the attached Figure 5 As shown:

[0023] Example 1: The utility model provides a chain inner link plate structure, including an outer chain component 1 and an inner chain component 2, the outer chain component 1 includes an outer chain link 101, a connecting pin 102, an outer chain plate 103 and a blocking buckle 104, the connecting pin 102 is fixedly installed on the side of the outer chain link 101, and the outer chain plate 103 is inserted into the outside of the connecting pin 102, and the blocking buckle 104 is inserted into the outside of the connecting pin 102; the inner chain component 2 includes an inner chain link 201, a ball 202 and an inner chain plate 203, the inner chain link 201 is inserted into the outside of the connecting pin 102, and the ball 202 is inserted into the outside of the inner chain link 201, and the inner chain plate 203 is inserted into the outside of the connecting pin 102.

[0024] In the disclosed embodiment, a radially arranged lubrication groove 2031 is provided on the side of the inner link plate 203 facing the ball 202, and the outer end depth of the lubrication groove 2031 is less than the inner end depth. During use, when lubricating oil or grease is applied to the outside of the outer chain component 1 and the inner chain component 2, the lubricating oil or grease can cover the surface of the components of the outer chain component 1 and the inner chain component 2 to achieve lubrication operation. At the same time, the lubricating oil or grease can enter the connection part between the ball 202 and the inner chain plate 203 through the lubrication groove 2031, thereby lubricating the connection gap part, and can also lubricate the connection part between the ball 202 and the connecting pin 102. The lubrication effect is comprehensive, which greatly reduces friction loss and improves the durability of the device.

[0025] In the embodiment of the present disclosure, a blocking roller 2032 is provided inside the lubrication groove 2031, and the diameter of the blocking roller 2032 is smaller than the depth of the outer end of the lubrication groove 2031. During use, the inner end of the lubrication groove 2031 is deeper than the outer end, so that lubricating oil or grease can be poured into the inner end through the notch at the outer end of the lubrication groove 2031. The inner end is deeper and can store more lubricating oil or grease for lubrication. At the same time, under the action of the blocking roller 2032, the leakage of lubricating oil and grease can be effectively reduced. When the outer chain component 1 and the inner chain component 2 are in a downward state, the blocking roller 2032 falls to the outer end of the lubrication groove 2031 under the action of gravity, blocking the outer end gap of the lubrication groove 2031 to prevent the leakage of lubricating oil or grease inside the lubrication groove 2031. When the outer chain component 1 and the inner chain component 2 are in an upward state, the blocking roller 2032 will be inside the lubrication groove 2031 under the action of gravity, and will not hinder the operation of pouring lubricating oil or grease into the lubrication groove 2031, making it convenient and flexible to use.

[0026] In the disclosed embodiment, a weight-reducing groove 2033 is provided in the middle of the inner link plate 203. The inner link plate 203 and the outer link plate 103 are made of high-strength, wear-resistant materials. The contact parts of the outer chain component 1 and the inner chain component 2 are provided with a graphite coating. During use, the inner link plate 203, while ensuring strength and stability, reduces unnecessary material usage by providing the weight-reducing groove 2033, achieves a lightweight design, and reduces the overall weight. Self-lubricating material is applied to the contact surface of the inner link plate 203 to reduce the friction coefficient and wear rate of the chain during the transmission process.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, a chain can be formed by connecting a suitable number of outer chain components 1 and inner chain components 2, and used in the transmission system of a motorcycle. When lubricating oil or grease is applied to the outside of the outer chain component 1 and the inner chain component 2, the lubricating oil or grease can cover the surface of the components of the outer chain component 1 and the inner chain component 2 to achieve lubrication operation. At the same time, the lubricating oil or grease can enter the connection part of the ball 202 and the inner chain plate 203 through the lubrication groove 2031, thereby lubricating the connection gap part, and can also lubricate the connection part between the ball 202 and the connecting pin 102. The lubrication effect is comprehensive and the friction loss is greatly reduced. The inner end of the lubrication groove 2031 is deeper than the outer end, so that the lubricating oil or grease can be poured into the inner end from the notch part of the outer end of the lubrication groove 2031. The inner end is deeper and can store more lubricating oil or grease for lubrication. At the same time, when blocking the roller Under the action of 2032, the leakage of lubricating oil and grease can be effectively reduced. Specifically, when the outer chain component 1 and the inner chain component 2 are in a downward state, the blocking roller 2032 falls to the outer end of the lubrication groove 2031 under the action of gravity, and the outer end gap of the lubrication groove 2031 is blocked to prevent the leakage of lubricating oil or grease inside the lubrication groove 2031. When the outer chain component 1 and the inner chain component 2 are in an upward state, the blocking roller 2032 will be inside the lubrication groove 2031 under the action of gravity, and will not hinder the operation of pouring lubricating oil or grease into the lubrication groove 2031. Under the premise of ensuring strength and stability, the inner chain plate 203 is provided with a weight-reducing groove 2033 to reduce unnecessary material use, realize a lightweight design, and reduce the overall weight. Self-lubricating material is applied to the contact surface of the inner chain plate 203 to reduce the friction coefficient and wear rate of the chain during the transmission process.

[0029] In another embodiment, a lubrication groove 2031 is also provided on the side plate of the inner link 201, and a blocking roller 2032 is inserted into the lubrication groove 2031. The inner link 201 and the inner link plate 203 are used in conjunction with each other to achieve lubrication operations inside the gaps on both sides of the ball 202, further improving the durability and stability of the device.
