When the disassembly tool is used to disassemble the axle box 2 on the axle 1, a certain thrust is first applied to the axle 1, and one side surface of the baffle plate 4 will fit with the end surface of the motor mounting seat 5 on one side. At this time, the baffle plate 4 is used to limit the movement of the motor mounting seat 5 on one side along the thrust direction, and the axle 1 will not be restricted. The axle 1 can be separated from the axle box 2 under the action of the thrust. Due to the structure of the baffle plate 4 and the setting position of the axle box 2, the force-bearing part of the motor mounting seat 5 is the end surface of the motor mounting seat 5. The end face of the machine mounting seat 5 is a non-mounting surface, which will not affect the surface of the axle box 2 and its motor mounting seat hole after being subjected to force, ensuring that the axle box 2 and the motor mounting seat hole are in good condition without defects such as deformation or bumps; the end face of the motor mounting seat 5 has a large and flat force-bearing area, and the baffle 4 with an opening can have a large contact area with the end face of the motor mounting seat 5.
