Abstract

The utility model provides a chain coupler which comprises a coupler body. The coupler body is cylindrical, a through hole penetrating the coupler body is formed in the two ends of the coupler body, a key groove is formed in the inner walls of the through hole, a threaded hole is formed in the bottom face of the key groove in a penetrating mode, gear teeth are evenly distributed on the end portion of the side wall of the coupler body in the circumferential direction, a guiding sleeve is arranged on an end face of the coupler body, and zinc is galvanized on the surface of the coupler body. The chain coupler is simple in structure and convenient to assemble and disassemble, and when the chain coupler is disassembled, two shafts which are connected with the chain coupler do not need to be moved; the chain coupler is low in weight, has certain compensation capability, and is applied to high-temperature, wet and dusty working conditions, and is long in service life.

Description

Chain coupling

Technical field

The utility model relates to a kind of coupling, particularly a kind of chain coupling.

Background technique

On the heavy ore deposits such as excavator in machinery, usually use coupling and realize axial force transmission, due to the operation in the environment of high temperature, humidity and many dirt usually of the machinery such as excavator, common coupling is impaired or corrosion easily, cause fracture, serious threat workman's life safety, and common coupling is when mounted, and radial location is very inconvenient.

The model utility content

The technical problem that (one) will solve

It is convenient that the technical problems to be solved in the utility model is to provide a kind of installation location, and transmission is stable, the chain coupling of long service life.
