Problems solved by technology
[0002] During the operation of the machine tool, motor bearings may sometimes appear to be burned. According to the feedback from the locomotive depot, this phenomenon has occurred on the HXN3 locomotive, which will cause the output shaft of the traction motor to lock up. Gears, resulting in gears that cannot be reused, resulting in a substantial increase in the amount of compensation for the company
[0003] In view of the situation that the motor bearing of the HXN3 locomotive is burned and the locomotive cannot be used, the current solution is relatively simple and rough. The pinion is cut by electric welding on site, resulting in the disengagement of the driving gear and the driven gear to ensure the normal rotation of the wheelset
[0004] But its shortcomings are very obvious, 1) The operation method is relatively simple and rough, which is extremely destructive to the gear
2) On-site electric welding, if the protective measures are not in place, the welding slag will fall into the motor during the gas welding process, causing the motor to malfunction

Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing.
[0019] Considering the installation method of the bogie traction motor, the traction motor adopts the shaft-holding semi-suspension installation method. One end of the traction motor is rigidly entwined on the axle through the holding bearing, and the other end is elastically suspended on the beam or end beam of the bogie frame. The driving gear installed on the armature shaft of the traction motor and the driven gear fixed on the axle form a transmission device, and the traction motor drives the axle to rotate. With the help of the positioning function of the holding bearing, it is ensured that the armature shaft of the traction motor is parallel to the axle shaft, and the center distance of the large and small gears remains unchanged, thereby ensuring the normal meshing of the large and small gears. The driving gear and the driven gear are separated by means of lengthenin...

The invention discloses a tool device and method for separating a driving gear and a driven gear and for a locomotive. The driving gear and the driven gear are separated in the manner of lengthened bolts and cushion blocks. The lengthened mounting bolts of axle-holding box process holes are tightened to generate propelling force, a motor is forced to slowly move in a manner of being parallel to anaxle-holding box, and finally the driving gear and the driven gear are separated. The additional cost caused by motor bearing replacement is effectively reduced, and losses caused by electrical welding to other locomotive parts are avoided. The tool device and method are suitable for locomotive motor maintaining.
Description
technical field [0001] The invention relates to the technical field of locomotive maintenance. Background technique [0002] During the operation of the machine tool, motor bearings may sometimes appear to be burned. According to the feedback from the locomotive depot, this phenomenon has occurred on the HXN3 locomotive, which will cause the output shaft of the traction motor to lock up. As a result, the gears cannot be reused, and the compensation amount of the company has increased significantly. [0003] In view of the motor bearing burnout of the HXN3 locomotive and the locomotive being unable to operate, the current solution is relatively simple and rough. The pinion is cut by electric welding on site, resulting in the disengagement of the driving gear and the driven gear to ensure the normal rotation of the wheelset. [0004] But its shortcoming is very obvious, 1) operation method is relatively simple and crude, extremely destructive to gear. 2) On-site electric wel...
