Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle chains, in particular to a long-life and wear-resistant motorcycle chain. Background Art

[0002] Motorcycles are a common means of transportation for people. Today's motorcycles are divided into street motorcycles, road racing motorcycles, off-road motorcycles and ordinary motorcycles. The chain body is an indispensable part of a motorcycle. A long-life and wear-resistant motorcycle chain is a key factor in ensuring the performance and safety of the motorcycle.

[0003] A search revealed a wear-resistant motorcycle chain with announcement number CN219755236U, which utilizes chain technology and includes an inner plate and an outer plate. A partition is disposed on the inner plate, and a partition is disposed on the outer plate. The partitions on the inner and outer plates are positioned correspondingly. A connecting rod is disposed between the inner and outer plates, and a rotating drum is sleeved on the connecting rod. The utility model provides partitions and side plates on the inner walls and side ends of the inner and outer plates, respectively, so that the partitions and side plates can wrap around the inner and outer plates. This arrangement prevents splashing of muddy water. A rotating drum is disposed on the connecting rod between the inner and outer plates to prevent wear of the connecting rod by the teeth. This arrangement makes the chain more wear-resistant and extends its service life.

[0004] Based on the above patent, a rotating drum is provided on the connecting rod between the inner plate and the outer plate, the rotating drum is sleeved on the connecting rod, and a spring piece is provided inside the rotating drum. A ball is provided between each spring piece, and the ball is in direct contact with the connecting rod, thereby reducing the friction between the inside of the rotating drum and the connecting rod. By providing the rotating drum on the connecting rod, the teeth can be prevented from directly contacting the connecting rod, thereby avoiding wear of the connecting rod. The setting can make the chain as a whole more wear-resistant and extend the service life of the chain. However, during use in this patent, when the sprocket rotates, the friction on the chain is large, so that the chain links, chain pins and chain rings wear faster than normal, which not only shortens the service life of the chain, but also causes the chain to break during driving. Utility Model Content

[0013] Furthermore, rolling bearing balls are installed on the inner walls of the mating chute, and the outer walls of the top ends of the rolling bearing balls are in close contact with the inner walls of the auxiliary chute.

[0014] Furthermore, one opposite end of the fixing column is detachably connected to the inner wall of the fixing slot, and the thickness and diameter of the fixing column are the same as the diameter of the inner wall of the fixing slot.

[0015] The utility model has the following beneficial effects:

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-3 The utility model provides an embodiment of a long-life wear-resistant motorcycle chain, including a wear-resistant chain plate 1, each of the wear-resistant chain plates 1 is fixedly connected to a reinforcement side plate 2 at one opposite end, and an alloy chain link plate 3 is installed at the opposite end of the reinforcement side plate 2. The left and right sides of the front end of the rear end wear-resistant chain plate 1 are fixedly connected to the mounting coupling 5, and the outer wall of the front end of the mounting coupling 5 is detachably connected to the assembly connecting block 6, and the outer wall of the mounting coupling 5 is fixedly connected to a fitting fixing tube 7, and the outer wall of the fitting fixing tube 7 is slidably connected to a smooth rotating drum 4, and the inner wall of the assembly connecting block 6 is fixedly connected to a fixed elastic ring 10.

[0027] Specifically: after placing the chain at the sprocket, the wear-resistant chain plate 1 can be assembled by installing the connecting shaft 5, and the alloy chain link plate 3 can assemble the wear-resistant chain plate 1 to form a complete chain. The surface of the wear-resistant chain plate 1 is covered with tungsten alloy material, so that the wear-resistant chain plate 1 has high density, high hardness and excellent wear resistance, and it is not afraid of rain corrosion, and the reinforced side plate 2 has stronger mechanical hardness for the wear-resistant chain plate 1. The alloy chain link plate 3 adopts a nickel-based superalloy coating to improve the hardness, wear resistance, high temperature resistance and corrosion resistance of the alloy chain link plate 3. The fixed elastic ring 10 is made of elastic material and has a certain elastic effect. The surface of the smooth rotating drum 4 is smooth, and it is coated with a titanium alloy coating, so that it has high strength, low density and good corrosion resistance.

[0028] Reference Figure 4-Figure 6 , the top of the inner wall of the smooth rotating cylinder 4 is provided with an auxiliary slide groove 13, the outer wall of the fitting fixed tube 7 is provided with a fitting slide groove 8, the inner diameter of the fixed elastic ring 10 is fixedly connected to a number of fixed columns 11, and the outer wall of the front end of the installation connecting shaft 5 is provided with a fixed slide groove 12. The opposite end of the alloy chain link plate 3 is tightly attached to the outer walls of the front and rear ends of the smooth rotating cylinder 4. The outer wall thickness of the reinforced side plate 2 and the outer wall thickness of the alloy chain link plate 3 are both 2mm. The inner diameter of the fitting slide groove 8 and the inner diameter of the auxiliary slide groove 13 are both 3mm. Rolling bearing balls 9 are installed on the inner wall of the fitting slide groove 8. The outer wall of the top of the rolling bearing ball 9 is tightly attached to the inner wall of the auxiliary slide groove 13. The opposite end of the fixed column 11 is detachably connected to the inner wall of the fixed slide groove 12, and the thickness and diameter of the fixed column 11 are the same as the inner wall diameter of the fixed slide groove 12.

[0029] Specifically: after the chain is installed at the sprocket, the surface of the smooth drum 4 is smooth, and the auxiliary slide groove 13 in the smooth drum 4 is acted upon by the rolling bearing balls 9. When the rolling bearing balls 9 transmit the sprocket, the rolling bearing balls 9 are connected by several bearing balls and can rotate with each other to offset the torque generated by them, thereby avoiding the friction generated when the sprocket rotates to generate stress on the wear-resistant chain plate 1 and the reinforcement side plate 2, thereby reducing the risk of breakage of the wear-resistant chain plate 1 and the reinforcement side plate 2. After the assembly connecting block 6 is installed at the installation coupling 5, the fixed elastic ring 10 fixes the fixed column 11 in the fixed slide groove 12 through elastic force, thereby avoiding the assembly connecting block 6 from falling off after being installed at the installation coupling 5, thereby improving the connection effect between the wear-resistant chain plate 1 and the reinforcement side plate 2, and extending the service life of the chain.

[0030] Working principle: After the chain is placed on the sprocket, the wear-resistant chain plate 1 can be assembled by installing the coupling 5, and the alloy chain link plate 3 can assemble the wear-resistant chain plate 1 to form a complete chain. After the chain is installed on the sprocket, the surface of the smooth drum 4 is smooth, and the auxiliary slide 13 in the smooth drum 4 is acted upon by the rolling bearing balls 9, so that the rolling bearing balls 9 offset the torque generated when the sprocket rotates, thereby avoiding the friction generated when the sprocket rotates to generate stress on the wear-resistant chain plate 1 and the reinforcement side plate 2, thereby reducing the risk of breakage of the wear-resistant chain plate 1 and the reinforcement side plate 2. After the assembly connecting block 6 is installed at the installation coupling 5, the fixed elastic ring 10 fixes the fixed column 11 in the fixed slide 12 through elastic force, thereby avoiding the assembly connecting block 6 from falling off after being installed on the installation coupling 5, thereby improving the connection effect between the wear-resistant chain plate 1 and the reinforcement side plate 2, and extending the service life of the chain.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
