Ultra-stable fatigue-resistant pintle chain

Abstract

The invention provides an ultra-stable fatigue-resistant pintle chain, and relates to the technical field of chain equipment. An ultra-stable fatigue-resistant pintle chain comprises connecting single bodies, each connecting single body comprises two chain plates, an inner section plate and a pin shaft, the two ends of each inner section plate are fixedly connected with the two chain plates respectively, and the two ends of the pin shaft of each connecting unit sequentially penetrate through the connecting unit and the two chain plates of the next connecting unit. When the pintle chain is subjected to large-load negative pressure in the working process, due to the existence of the main reinforcing ribs, the pressure borne by the two chain plates can be shared, the stress integrity of the chain plates is too high, meanwhile, due to the existence of the auxiliary reinforcing ribs, the stress integrity between the chain plates and the inner section plates can be improved, and the influence of too large local load of the chain on the service cycle of the chain is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of chain equipment, and particularly to an ultra-stable fatigue-resistant pin-connected chain. Background Art

[0002] A pin-connected chain is a mechanical transmission or conveying chain that connects chain links with steel pins. Its core features are simple chain link structure, stable connection, and strong adaptability. It is widely used in material conveying and specific transmission scenarios in industrial production. The chain links of a pin-connected chain are usually made of malleable cast iron or high-strength steel plates, and are horizontally connected by steel pins. Its chain links are of an integral bending structure without distinction between inner and outer chain links. The pins pass through the chain links to form a rigid connection, ensuring the stability of the chain under load.

[0003] Traditional pin-connected chains can ensure stability in most usage scenarios during use, but high-load continuous operation scenarios affect their service life. Summary of the Invention

[0004] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides an ultra-stable fatigue-resistant pin-connected chain, which solves the problem that high-load continuous operation scenarios affect its service life.

[0005] (II) Technical Solutions To achieve the above objectives, the present invention is realized through the following technical solutions: An ultra-stable fatigue-resistant pin-connected chain includes connection monomers. Each connection monomer includes two chain plates, one inner joint plate, and one pin. The two ends of the inner joint plate are respectively fixedly connected to the two chain plates. The two ends of the pin of each connection unit sequentially penetrate the two chain plates of this connection unit and the next one. Stabilizing structures are arranged on both the front and rear sides of each connection monomer. The stabilizing structure includes a main reinforcing rib. The two ends of the main reinforcing rib are respectively connected to the side walls of the two chain plates in the same connection monomer. Two secondary reinforcing ribs are fixedly connected to the side wall of the main reinforcing rib. The ends of the two secondary reinforcing ribs fixedly connected to the same main reinforcing rib and away from the main reinforcing rib are fixedly connected to the side wall of the inner joint plate.

[0006] Working Principle: During use, when the pin-connected chain is working and is subjected to a large load negative pressure, due to the presence of the main reinforcing rib, the pressure borne by the two chain plates will be shared, improving the overall stress integrity of the chain plates. At the same time, the presence of the secondary reinforcing ribs can improve the overall stress integrity between the chain plates and the inner joint plate, reducing the impact of excessive local load on the service life of the chain.

[0007] (III) Beneficial Effects The present invention provides an ultra-stable fatigue-resistant pin-connected chain, which has the following beneficial effects: When the super-stable fatigue-resistant pin-connected chain is working and is subjected to a large load negative pressure, due to the existence of the main reinforcing rib, the pressure borne by the two chain plates will be shared, improving the overall stress-bearing capacity of the chain plates. At the same time, the existence of the secondary reinforcing rib can improve the overall stress-bearing capacity between the chain plate and the inner joint plate, reducing the influence of excessive local load on the service life of the chain.
