A single-side positioning method for the main shaft of a garbage double-shaft shredder

Abstract

The invention discloses a garbage double-shaft crusher main shaft single-side positioning method. According to the assembling method, the single-direction positioning structure is adopted, the structural design for a main shaft assembly is regulated, and therefore it is ensured that two main shaft assemblies can be locked from the same single side when the installation directions are opposite, andtherefore the problems that due to machining error problems of tools and spacer bushes, assembling cannot be performed, the tools are crossed, and friction is caused are solved, meanwhile, tool resistance generated by friction is eliminated, the noise problem generated by friction is eliminated, and the energy efficiency is lost. Meanwhile, the problem of assembling reworking is solved. The method can effectively ensure the effective clearance of 0.1-0.3 MM needed when the crossed tools on double shafts of a crusher are used for shearing, meanwhile, the phenomena that due to machining errors,installing cannot be achieved, tools are abraded, and tool collision is caused can be greatly reduced, meanwhile, the installing and maintaining time is shortened, and the structure is applicable tovarious equipment machines similar to crushers in shear type cross operation.

Description

technical field [0001] The invention relates to a garbage double-shaft shredder, in particular to a unilateral positioning method for the main shaft of the garbage double-shaft shredder. Background technique [0002] The double-shaft crusher is driven by an electric motor or a hydraulic motor. The knives are made of special alloy steel and controlled by a programmable logic controller. It can be automatically reversed when encountering hard objects. The output size can be designed according to user requirements. Different thickness of the knives. The rotation speed of the cutter shaft is generally optional at 10-70 revolutions per minute. With the increasing amount of solid waste today, the country's demand for crushing equipment for waste disposal is also increasing. In order to ensure that the crusher does not sharpen the knife when it is broken, how to ensure the gap between the two shafts when assembling the cutter box is the core technology of the crusher. [0003] At...

AI Technical Summary

Problems solved by technology

[0003] At present, the positioning structure of the conventional tool box assembly is double-axis positioning at both ends. After installation, the tools assembled on the two main shafts often sharpen each other. Even because of a collision of 0.1-0.2 millimeters, the installation cannot be installed, and it is disassembled again. down to rework

Sometimes increased noise during frictional operation and wears out the tool and loses power to the motor
