Device and method for chain demounting

Abstract

The device discloses a device for chain demounting. The device comprises a bearing base and a buckle cover. The bearing base is provided with a placing groove where a chain is placed, avoiding groovesmatched with pin shafts of the chain are arranged at the bottom of the placing groove, a discharge hole communicates with the bottom of the avoiding groove located in the middle, an ejection shaft used for ejecting out the pin shaft located over the discharge hole is arranged on the buckle cover in an up-down moving mode, and the bearing base and the buckle cover are connected through a supporting device. In the operation process, chain sections on the two sides of the pin shaft to be demounted are directly positioned, chain torque is effectively neutralized, no extra staff is needed for auxiliary operation, the demounting process can be completed through one person, the working efficiency is improved, and the chain is prevented from being damaged in the demounting process.

Problems solved by technology

[0002] In daily life, chain transmission is one of the three major mechanical transmission methods. It has no elastic sliding and slipping, can maintain an accurate average transmission ratio, requires small tension, and the pressure on the shaft is also small, which can reduce The friction loss of the bearing, when the center distance between the driving wheel and the driven wheel is required to be large, its transmission structure is simple, and it can work under harsh environmental conditions such as high temperature and oil pollution, and is widely used in industrial machinery, agricultural machinery, and machine tools. In the chain repair and maintenance work, ordinary tools such as hammers and pliers are generally used to knock the chain pin to achieve the purpose of disassembly. However, this traditional method often takes a long time and is easy to cause physical deformation of the chain. During the disassembly process, single-point positioning is adopted, and only the pin shaft of the chain is positioned. Since the length of the chain in use is relatively long, the positioning is affected by the torsion of the entire chain during positioning. trouble
