[0001] The utility model relates to the technical field of rail vehicle tooling, in particular to a disassembly and assembly device for a rubber sleeve of a slideway roller of an EMU. Background Art

[0002] The existing disassembly and assembly of rubber sleeves for slideway rollers of EMUs, especially the disassembly and assembly of rubber sleeves for slideway rollers on plug doors, is mainly done by manually removing the entire roller from the fixing frame, and then removing the rubber sleeve with the help of tools. The operation process is as follows: after the worker removes the upper slideway, he removes the nut at the rear end of the fixing screw of the upper slideway roller with a wrench, and then uses a wrench to clamp the middle rectangular section of the fixing screw to remove the upper slideway roller from the fixing frame, and uses a small tool to remove the old rubber sleeve on the auxiliary wheel and replace it with a new rubber sleeve, and finally installs the upper slideway roller to the fixing frame. Due to the narrow space where the upper slideway roller is installed, the disassembly and assembly process is difficult, and the operation process takes a long time, consumes manpower, and has low work efficiency. For this reason, we propose a disassembly and assembly device for the rubber sleeve of the slideway roller of the plug door of an EMU for a narrow space. Utility Model Content
