Problems solved by technology

[0003] At present, 5GEB32B1 AC traction motors have frequent failures outside the factory. After the motors are returned to the factory for disassembly and inspection, more than 90% of the failures of the traction motors are due to the desoldering of the rotor guide bar, scratching the stator coil and causing the motor to be grounded.
The company's existing DC traction motor rotor maintenance process cannot effectively prevent the desoldering of the 5GEB32B1 AC traction motor rotor guide bar, and cannot guarantee that the rotor after the replacement of the squirrel cage will no longer have desoldering of the guide bar

Embodiment Construction

[0020] In order to ensure the quality of the rotor after replacing the squirrel cage, reduce the movement of the guide bars in the notch of the silicon steel sheet, and prevent the phenomenon of bar de-soldering in the rotors that have not yet had de-soldering of the guide bars, it is necessary All the guide bars of the rotor are newly expanded and tightened, and all the guide bars of the rotor after replacing the new squirrel cage are expanded and tightened to eliminate the phenomenon that the guide bars are lifted or broken, thereby improving the life of the rotor.

[0021] Such as figure 1 and figure 2 As shown, it is the tightening tool for the rotor guide bar of the AC traction motor, including the punch 1, the punch guide seat 2, the stud bolt 3, the coupling rod 4 and the positioning block 5, the punch 1 is placed on the punch guide seat 2, and the punch The front end of the head guide seat 2 is connected to the connecting rod 4 by a stud bolt 3 , and a positioning bl...

Abstract

The invention relates to the technical field of alternating current traction motors, in particular to an alternating current traction motor guide strip tensioning tool and method thereof. The alternating current traction motor guide strip tensioning tool comprises a puncher pin, a puncher pin guide base, double-end bolt, a linkage rod and a positioning block. The puncher pin is arranged on the puncher pin guide base. The front end of the puncher pin guide base is connected with the linkage rod through the double-end bolt. The positioning block is arranged at the most front end of the linkage rod. The alternating current traction motor guide strip tensioning tool is simple in structure, and overhauling pressure of a locomotive shop and a locomotive inspection and repair sections can be effectively relieved by means of the tensioning method of the tensioning tool.

Description

technical field [0001] The invention relates to a method for tightening a rotor guide bar, in particular to a tool for tightening a rotor guide bar of an AC traction motor and a tightening method thereof. Background technique [0002] The HXN5 locomotive, a freight diesel locomotive for China's main railway lines, is equipped with a 5GEB32B1 AC traction motor, which was developed by General Electric (GE) of the United States. [0003] At present, 5GEB32B1 AC traction motors have frequent failures outside the factory. After the motors are returned to the factory for dismantling and inspection, more than 90% of the failures of the traction motors are due to the desoldering of the rotor guide bar, scratching the stator coil, and causing the motor to be grounded. The company's existing DC traction motor rotor maintenance process cannot effectively prevent the desoldering of the rotor guide bar of the 5GEB32B1 AC traction motor, and cannot guarantee that the desoldering of the ro...
