Chain, chain coupler and connecting method of chain coupler

Abstract

The invention provides a chain. The chain comprises a first chain body and a second chain body, wherein the first chain body and the second chain body are arranged side by side and share one pin shaft, and the first chain body and the second chain body are each provided with a first tail end chain link, a second tail end chain link and a tail end pin shaft; the first tail end chain links are arranged at one end of the first chain body and the second chain body, and the second tail end chain links are located at the other end of the first chain body and the other end of the second chain body; and a connecting chain link of the chain comprises at least one clamping piece, a connecting pin shaft, a first connecting piece and a second connecting piece. The clamping piece is located between the first chain link and the second chain link and is provided with a first joint portion, a second joint portion and at least one connecting pin shaft hole, wherein the first joint portion and the second joint portion can be connected with the two tail end pin shafts respectively; the connecting pin shaft penetrates the connecting pin shaft hole of the clamping piece; the first connecting piece and the second connecting piece are mounted on the outer side of the first chain body and the outer side of the second chain body, are each provided with at least three holes and are suitable for being matched with the tail end of the first tail end pin shaft, the tail end of the second tail end pin shaft and the tail end of the connecting pin shaft. The invention further discloses a chain coupler with the chain. The chain and the chain coupler can be mounted in small and narrow mounting space, and sufficient connecting strength and sufficient structural stability are achieved.

Description

technical field [0001] The present invention relates to a chain and a method for connecting the chain, more particularly to a chain coupling and a method for connecting the chain coupling. Background technique [0002] A chain is typically used as a transmission structure, usually looping around two sprockets to transmit power between them. In addition, the chain can also be used as a coupling connecting two shafts to realize the linkage between the two shafts. For example, in combine harvesters, especially corn harvesters, most of the corn harvesting heads use chain couplings, especially double-row chains as couplings between adjacent gearboxes to achieve power transmission; In this case, due to the small distance between the side walls of the gearbox, especially when the distance is less than the length of the chain joint pin, there is not enough space for the joint pins connecting the double-row chains to complete the assembly connection. In addition to meeting the limi...
