Problems solved by technology

Since the diameter of the shaft sleeve is smaller than the height of the chain plate, the items being transported will be directly pressed against the chain plate. When the items are heavy, the chain is very easy to be crushed, which will shorten the service life of the chain and affect the normal and continuous transportation of items.

Embodiment Construction

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings; it should be noted that the embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0016] A wear-resistant chain includes a plurality of chain link units connected end to end, each chain link unit includes two chain plates 3 arranged side by side, and the chain plates of two adjacent chain link units are connected by connecting shafts 5, each A shaft sleeve 4 is fixed coaxially on each of the connecting shafts, and both ends of the shaft sleeve are pressed against the inner side walls of the two chain plates respectively. Since the above is the prior art, it will not be repeated here.

[0017] The innovation of the present invention lies in that a wear-resistant sleeve 2 is coaxially rotatably fitted on the outside of each shaft sleeve.

[0018] A connecting plate 1 is installed on the outer sid...

Abstract

The invention relates to an abrasion-resisting chain. The abrasion-resisting chain comprises a plurality of chain link units which are connected in an end-to-end mode. Each chain link unit comprises two chain boards which are arranged side by side, the chain boards of every two adjacent chain link units are connected through connecting shafts, a shaft sleeve is fixedly installed on each connecting shaft coaxially, the two ends of each shaft sleeve abut against the inner lateral walls of two corresponding chain boards respectively, an abrasion-resisting sleeve is coaxially arranged on the outer side of each shaft sleeve in a sleeved mode, and the diameter of each abrasion-resisting sleeve is larger than the height of each chain board. The abrasion-resisting chain is ingenious in design, reasonable in improvement, simple in structure, high in abrasion resistance, long in service life, and particularly suitable for transportation of heavy goods.

Description

technical field [0001] The invention relates to the field of chains, in particular to a wear-resistant chain. Background technique [0002] A chain is a combination of components connected in series by the same or equally spaced components in the form of a kinematic pair. The existing chain is usually formed by connecting a plurality of chain link units end to end, each chain link unit includes two chain plates arranged side by side, and the chain plates of two adjacent chain link units are connected by connecting shafts, and each connection Shaft sleeves are set on the shaft. Since the diameter of the shaft sleeve is smaller than the height of the chain plate, the items to be transported will be directly pressed on the chain plate. When the item is heavy, it is very easy to crush the chain, which will shorten the service life of the chain and affect the normal and continuous transportation of the items. SUMMARY OF THE INVENTION [0003] The purpose of the present invent...
