Abstract

The invention discloses a special tool for disassembly of a controlling gear of a locomotive diesel engine, and belongs to the technical field of internal combustion locomotive maintenance. The special tool comprises a main plate, a threaded lead screw, an adjusting nut and a drawing piece, wherein the main plate is provided with a first threaded hole and a plurality of second threaded holes uniformly distributed in the circumferential direction of the first threaded hole, the threaded lead screw penetrates through the first threaded hole and is in threaded fit with the first threaded hole, the threaded lead screw is locked through an adjusting nut positioned on one side of the main plate, two ends of the drawing piece are provided with threads, and the threads on one end of the drawing piece is in threaded fit with the second threaded holes on the main plate. The special tool is not only simple and light in structure and high in disassembly efficiency, but also does not damage the control gear and the stop keyboard.

Description

technical field [0001] The invention belongs to the technical field of maintenance of diesel locomotives, and in particular relates to a special tool used for dismantling regulating gears of locomotive diesel engines. Background technique [0002] For the dismounting of the control gear of the diesel locomotive diesel engine, in order to reduce the operation to the control gear, at present the mode of manual knocking is mainly adopted to remove and separate the control gear and the stop keyboard with interference fit in the middle. This kind of disassembly operation method is difficult to disassemble, and the process is cumbersome. Not only is the labor intensity high and the efficiency is low, but also because the force and direction of the knocking are not easy to control, it is easy to cause damage to the mounting hole of the regulating gear. Contents of the invention [0003] In order to overcome the problems in the prior art, the present invention provides a special t...
