A chain with variable pitch and large load

Abstract

The invention relates to the field of chains, in particular to a chain with variable pitch and large load, which comprises two symmetrically arranged outer chain plates, four inner chain plates are symmetrically and flexibly connected between the two outer chain plates, and the four inner chain plates are It is divided into two groups and each group is composed of two symmetrically arranged inner chain plates. Two limit shafts are symmetrically fixed on the outer walls of the four inner chain plates. One end is inserted into the matching outer chain plate, and two buffer mechanisms are installed symmetrically on the two outer chain plates, and the two ends of the four buffer mechanisms are inserted into the matching inner chain plate Two pin shafts are rotated between the two inner chain plates set in the group, and a roller is sleeved on each of the four pin shafts, and a central shaft is arranged inside the four pin shafts. The chain can adjust the roller The distance between the barrels, and then the chain pitch can be changed, and it can be sleeved on sprockets of different specifications, which greatly improves its scope of application.

Description

Technical field [0001] The present invention relates to the field of chain, and specifically a variable pitch large load chain. Background technique [0002] Chain is generally metal chain or annular, mostly used as mechanical transmission, traction, most chains consist of chain plates, chain pins, bushing, etc. Different division specifications of extreme tensile load, especially large load chains, often used in large devices, chains need to be larger tensile, and their body type is also larger than ordinary chains, the greater the chain pitch, and chain velocity changes and chains The larger the moving load caused by the fence in which the roll-in sprocket is impulted. [0003] The traditional large load chain is unable to adjust the chain pitch during the actual use. The same size chain cannot be attached to different sprockets, which greatly reduces its applicable scope, in this, need to design a variable distance large Load chain. Inventive content [0004] For problems in ...

AI Technical Summary

Problems solved by technology

[0003] In the actual use of traditional large-load chains, the chain pitch cannot be adjusted, and chains of the same specification cannot be socketed and installed on different sprockets, which greatly reduces its scope of application. For this, it is necessary to design a variable pitch large load chain
