Embodiment Construction

[0013] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0014] A chain middle sleeve for an amphibious excavator comprises a cylindrical middle sleeve main body 1, and an axial hole 3 is formed on the shaft center of the cylindrical middle sleeve main body. The innovation point of the present invention is: an outer cover 2 is made coaxially outside the middle part of the main body of the cylindrical middle cover. The upper end surface and the lower end surface of the tubular middle sleeve main body located on the left and right sides of the overcoat are all made into plane 4 .

Abstract

The invention relates to a medium chain sleeve for an amphibious excavator. The medium chain sleeve comprises a tubular medium sleeve body, a shaft hole is processed in the axis of the tubular medium sleeve body, an outer sleeve is processed on the outer side of the middle of the tubular medium sleeve body coaxially, and an upper end face and a lower end face, located on the left and right side of the outer sleeve, of the tubular medium sleeve body are processed into planes. The medium chain sleeve for the amphibious excavator is scientific in design, reasonable in improvement, easy to manufacture and convenient to used and is of an integrated structure, and the upper end face and the lower end face, located on the left and right side of the outer sleeve, of the tubular medium sleeve body are processed into the planes, so that sludge can be prevented from entering clearances, friction is reduced, and service life is prolonged.

Description

technical field [0001] The invention relates to the field of chains, in particular to a chain middle sleeve for an amphibious excavator. Background technique [0002] At present, there are rollers on the outside of the chain used by the amphibious excavator, and there is a gap between the roller and the chain sleeve. Therefore, during the use of the amphibious excavator, silt will enter the gap, causing wear and tear, and affecting the service life of the chain. Contents of the invention [0003] The object of the present invention is to provide a middle sleeve for amphibious excavator chains with reasonable design, simple structure, reduced wear, and extended chain service life. [0004] The purpose of the present invention is achieved by the following technical means: [0005] A middle sleeve for a chain for an amphibious excavator, comprising a cylindrical middle sleeve main body, an axis hole is formed on the axis of the cylindrical middle sleeve main body, and it is ...
