Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveyor chains, in particular to a novel wear-resistant double-speed chain. Background Art
[0002] Chains are commonly used and important products in conveying and rotating equipment. A double-speed chain is a chain in which the material conveying speed is greater than the chain conveying speed. During the production of existing double-speed chains, the main body of the chain is composed of a sleeve and a separate roller structure. The roller's movement fluency is relatively poor during use, and it is difficult to achieve consistent stability when conveying materials between the chain links during use. During use, the matching position between the roller and the track is prone to slippage, and there is sliding friction during use. During use, the structure of the matching position will be worn during use, and the overall life will also be affected. The existing sleeve is processed by the precision drawn tube production method, and the production cost is relatively high. Utility Model Content
[0003] The purpose of this utility model is to provide a new type of wear-resistant double-speed chain, which arranges the roller structure of the chain into two groups of roller assemblies that cooperate with each other, and the internal cooperation position is arranged into a hollow structure. During use, the chain can achieve rolling friction cooperation as a whole, so that the overall wear resistance of the chain is better, the service life is longer, and the stability during use is also better. Lubricating liquid can be set in the internal space between the rollers as needed to ensure that the roller structure of the main body of the chain can have smoother movement when the chain is used, thereby ensuring better smoothness when the chain moves, and effectively improving the overall bearing strength of the chain, so that the transportation process is more stable, and the overall structural safety is higher. The sleeve adopts a cold extrusion production method to ensure that the overall production cost is lower, and the sleeve and roller end positions are both arranged to exceed the outer end face of the cooperation position. There is a certain space between the cooperation positions of the components to avoid direct contact and easy wear during use.

[0016] like Figures 1 to 4As shown, a new wear-resistant double-speed chain comprises a first roller body 4 with a cylindrical outer surface. Second roller bodies 3 are connected to either side of the first roller body 4, forming the overall structure of the roller assembly. A combined stabilizing connecting post is provided at the center axis of the first roller body 4. The center assembly hole of the second roller body 3 mates with the combined stabilizing connecting post, ensuring greater structural strength at the mating position. A combined mounting groove 41 is provided on the end face of the first roller body 4. A conical stabilizing combined mounting post 31 is mounted within the combined mounting groove 41. An assembly stop safety post is provided on the inner end face of the combined mounting groove 41, along the thickness direction of the center axis, to mate with the stabilizing combined mounting post 31, ensuring greater assembly precision at the mating position. A movable safety space is formed between the inner end face of the stabilizing combined mounting post 31 and the inner end face of the combined mounting groove 41. This space ensures a certain amount of space inside during use, which can be used for heat dissipation and ventilation, or for lubricating liquid. This ensures greater overall safety during chain use. A sleeve 2 is provided at the center of the first roller body 4. A main body connecting pin 6 is connected to the central axis of the sleeve 2. Inner link plates 1 are connected to both ends of the outer side of the first roller body 4. Outer link plates 5 are provided on the outer sides of the inner link plates 1. The outer sides of the main body connecting pin 6 are fastened via locking anti-slip features 7. Both end faces at the center of the first roller body 4 extend beyond the outer end faces of the second roller body 3. Both end faces at the center of the sleeve 2 extend beyond the plane of the outer end faces of the inner link plates 1. This creates a certain amount of space between the mating positions, preventing wear caused by large-area contact during use and improving overall wear resistance during use. It sets the roller structure of the chain into two groups of roller assemblies that cooperate with each other, and the internal cooperation position is set to a hollow structure. During use, the chain can achieve rolling friction cooperation as a whole, so that the overall wear resistance of the chain is better, the service life is longer, and the stability during use is also better. Lubricating liquid can be set in the internal space between the rollers as needed to ensure that the roller structure of the main body of the chain can have smoother movement when the chain is in use, ensuring better smoothness when the chain moves, and effectively improving the overall bearing strength of the chain, making the transportation process more stable and the overall structural safety higher. The sleeve adopts a cold extrusion production method to ensure lower overall production costs, and the sleeve and roller end positions are set to a structure that exceeds the outer end face of the cooperation position, so that there is a certain space between the cooperation positions of the components to avoid direct contact and easy wear during use.
[0017] Preferably, the distance by which both side end faces of the center position of the first roller body 4 extend beyond the outer end face of the second roller body 3 is greater than the distance by which both side end faces of the center position of the sleeve 2 extend beyond the plane where the outer end face of the inner link plate 1 is located, so that the space in the middle position is larger and the safety is higher when the chain is moving.
[0018] Preferably, the lower end of the stabilizing combination fitting column 31 is provided with an integrally formed cylindrical reinforcing stabilizing fitting column, so that the structural strength of this position is better, the bearing capacity is stronger during use, and the durability during use is also better.
[0019] Preferably, the sleeve 2 is produced by cold extrusion, which reduces the production cost.
[0020] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
