Because the service life of the chain is shorter, the operation and maintenance workload and the maintenance cost are larger, and the safety is also not ideal, the ring chain needs to be improved to improve the service life of the ring chain, or the processing cost of the chain is reduced. In the prior art, as disclosed in the patent with publication number of CN210770032U, a wear-resistant layer is arranged at the inner annular cambered surface of a single chain link, so that the abrasion between the chain links during hoisting traction is reduced, and the service life of the chain is longer. The arrangement of the wear-resistant layer is also an effective method, so that it can be seen how to improve various performances of the chain under different working conditions and to improve the service life of the chain.
For this reason, we have found that the above-mentioned problems can be solved to some extent by designing the reducing chain links, and the reducing chain composed of the reducing chain links connected sequentially in order.
Circular ring chains in the current market are divided into two types: the first is a general circular chain, which is formed by cutting a steel rod into sections, and then braiding the sections into a chain through hot bending and welding (see figure 1), wherein the diameter of the chain cannot be changed; the second type is a flat chain, which is characterized by comprising two chain links, one is a forged flat chain link, and the other is a forged flat chain link obtained by cutting a steel bar into sections and then hot-bending and welding the steel bar onto the forged flat chain link. Such chains also fail to achieve a variation in the diameter of each link (see fig. 2 and 3).
