Multi-section type cantilever roller roller shaft connection structure

Abstract

The invention discloses a multi-section type cantilever roller roller shaft connection structure, comprising a shaft body. A roller body sleeves the outer side, close to the left side, of the shaft body. A fixing ring fixedly sleeves on the outer side surface, close to the right end of the roller body, of the shaft body. A square block is fixedly connected to the left end surface of the fixing ring. A mounting groove is formed on the right end surface of the roller body. A threaded groove is formed on the inner left end of the mounting groove. A clamping bolt is penetrated through the fixing ring. A connecting ring is arranged on the side surface, near the left end of the roller body, of the shaft body. The roller shaft connection structure has a convenient installation function, replacesa traditional pure bolt installation method, avoids the clamping bolt from wearing and breaking, improves the stability of the roller body rotation, and is also convenient for the staff to disassemblethe roller body for maintenance. The roller shaft connection structure can prevent dust and water in the air from falling on the outer surface of the roller body, prevent the roller body from being impacted by the outside, improve the service life of the roller body, and have a good protective function.

Description

technical field [0001] The invention relates to the field of cantilever rollers, in particular to a multi-stage cantilever roller shaft connection structure. Background technique [0002] At present, the roller shaft connection structure of most cantilever rollers is the combination of flanges and bolts. When the shaft body starts and stops, the roller body will generate a large inertial force, so that the roller body will continue to rotate relative to the shaft. Cause the bolts to wear and tear, thus affecting the life safety of the staff; [0003] The roller shaft connection structure on the market usually does not have a convenient installation function. Generally, the installation method of pure bolts and flanges is used. The bolts are easy to wear and break when the shaft body is started and stopped, and it is not convenient for the staff to adjust the roller body. Disassembly and maintenance, and the dust and water in the air will fall on the joint between the roller...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-section cantilever roller shaft connection structure to solve the above-mentioned background technology. The roller shaft connection structure on the market usually does not have a convenient installation function, and generally uses pure bolts and flanges. The installation method, the bolts are easy to wear and break when the shaft body is started and stopped, and it is not convenient for the staff to disassemble and repair the roller body, and the dust and water in the air will fall to the joint between the roller body and the shaft body when the roller body is idle. The connection will affect its service life, and the roller body is vulnerable to external collisions and does not have a good protective function.
