Abstract
The invention discloses the tooling device and method that a kind of locomotive separates driving and driven gear, using Lengthened bolt, the mode of cushion block separates driving gear and driven gear.Being tightened using the lengthening installation bolt of axle suspension bearing box fabrication hole is made, and produces propulsive force, forces motor slowly to be moved parallel to axle suspension bearing box, and final driving gear departs from driven gear.Fringe cost caused by replacing motor bearings is effectively reduced, and avoids electrogas welding from causing the losses of other locomotive elements.Repaired suitable for locomotive engine.
Description
Technical field
The present invention relates to locomotive maintenance technical field.
Background technology
It sometimes appear that motor bearings scaling loss shows in lathe operational process, fed back according to locomotive depot, HXN3 locomotives just go out
Now cross it is this show, this can cause traction electric machine output shaft locking, and locomotive depot scene is directly cut by the way that electrogas welding is destructive, is cut
Pinion gear is cut, causes gear not reuse, causes Lian Che companies raising strong seedlings to be significantly increased.
In the case of causing locomotive not use for motor bearings scaling loss in HXN3 locomotive operations, processing scheme ratio at present
More simple and crude, scene carries out electrogas welding cutting pinion gear, causes driving gear to be disengaged with driven gear, ensures that wheel turns to normal
It is dynamic.
But its shortcoming is clearly, 1) operational means is fairly simple roughly, destructive greatly for gear.2) scene into
Row electrogas welding, if safeguard procedures are not in place, gas welding process causes welding slag to fall into motor internal, causes motor operational failure.
The content of the invention
Technical problem solved by the invention is to provide a kind of locomotive in reduction destructiveness, the integrality for ensureing gear and uses
Separate the tooling device and method of driving and driven gear.
The technical solution adopted by the present invention is the tooling device that locomotive separates driving and driven gear, including traction electric machine and
Original connection bolt between axle suspension bearing box, further includes Lengthened bolt one, and one length of Lengthened bolt is more than original connection bolt, lengthens
Bolt one replaces original connection bolt to be threaded into hole, further includes Lengthened bolt two, Lengthened bolt two is screwed into axle suspension bearing box
In four screw thread fabrication holes, installation cushion block is further included, installation cushion block is inserted between axle suspension bearing box and motor, and installation cushion block is equipped with
Groove, groove are adapted with Lengthened bolt one or Lengthened bolt two.
The method that locomotive separates driving and driven gear, comprises the following steps：
1) bolt between traction electric machine and axle suspension bearing box is replaced, original bolt is removed, is changed to Lengthened bolt one, bolt
It need to be replaced according to this, Lengthened bolt one is tightened；
2) Lengthened bolt two is installed in four screw thread fabrication holes of axle suspension bearing box；
3) in tightening technique hole after Lengthened bolt two, 8 Lengthened bolts one are uniformly unclamped, then by four fabrication holes
Lengthened bolt two is uniformly tightened, and ensures traction electric machine relative to the parallel movement of axle suspension bearing box；
4) alternately step 3 is repeated, until traction electric machine stops when moving in parallel about 21mm；
5) cushion block is installed, cushion block is inserted between axle suspension bearing box and motor from upper box part is seized.
6) remove and fill two Lengthened bolts two, two other fabrication hole Lengthened bolt two retains, while ensures Lengthened bolt
Two length for stretching out in axle suspension bearing box are fixed.8 Lengthened bolts one are tightened, ensure to be adjacent between axle suspension bearing box, cushion block, traction electric machine,
Fastening torque of bolt 1366Nm, and wear steel wire between each two Lengthened bolt one and tighten.
The beneficial effects of the invention are as follows can design two kinds of Lengthened bolts by simple and practicable tooling device and padded with a kind of
Block, reaches the effect for moving in parallel motor, ultimately results in driving and driven gear separation.Replacement motor bearings is effectively reduced to cause
Fringe cost, and avoid electrogas welding from causing the losses of other locomotive elements.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is a-quadrant enlarged drawing in Fig. 1.
In figure mark for：1- Lengthened bolts one, 2- Lengthened bolts two, 3- axle-hang box, 4- motors, 5- cushion blocks, 6- is actively
Gear, 7- driven gears.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
In view of bogie traction electric machine mounting means, for traction electric machine using half suspension mounting means is seized, traction is electronic
One end of machine is by axle suspension bearing rigidity obvolvent on axle, and other end resilient suspension is on the crossbeam or end carriage of bogie frame.
Driving gear of the installation on traction motor armature shaft and the driven gear composition transmission device being packed on axle, traction
Motor axle shaft turns round.By means of the positioning action of axle suspension bearing, it ensure that traction motor armature shaft is parallel with axle, and
The centre-to-centre spacing of big pinion gear remains unchanged, and ensure that the normal engagement of big pinion gear.Using Lengthened bolt, the mode of cushion block separates
Driving gear and driven gear.
Preparation：Gear-box lower box screw plug is first turned on, the gear lubricant in gear-box is all released；Then
Remove gear-box and gearbox seals ring.
Replace step：
1st, replace traction electric machine and be connected bolt with axle suspension bearing box.Original bolt is removed, the Lengthened bolt one more renewed.To protect
Card motor is not shifted or come off, and bolt need to be replaced according to this, will please don't again install Lengthened bolt one after all disassembling bolts,
Suitably tightened newly Lengthened bolt one is changed.
2nd, after the completion of connecting bolt replacement, new Lengthened bolt two is installed in four screw thread fabrication holes of axle suspension bearing box.
3rd, in tightening technique hole after Lengthened bolt two, 8 Lengthened bolts one are uniformly unclamped, then by four fabrication holes
Lengthened bolt two is uniformly tightened, and ensures traction electric machine relative to the parallel movement of axle suspension bearing box.
4th, alternately step 3 is repeated, until traction electric machine stops when moving in parallel about 21mm.At this time, driving and driven gear
Disengage.
The 5th, cushion block is installed, cushion block is inserted between axle suspension bearing box and motor from upper box part is seized.Totally 2 cushion blocks.
6th, remove equipped with the Lengthened bolt two in fabrication hole at cushion block, totally 2, two other fabrication hole Lengthened bolt two is protected
Stay, while ensure that Lengthened bolt two stretches out in the length of axle suspension bearing box and fixes.8 Lengthened bolts one are tightened, ensure axle suspension bearing box, pad
It is adjacent between block, traction electric machine, fastening torque of bolt 1366Nm, and wears steel wire between each two Lengthened bolt one and tighten, is prevented
Only bolt looseness.Driving and driven gear process end of operation is entirely separated, locomotive can be run again.
A kind of tooling device for separating driving and driven gear used in the present invention, according to the characteristics of equipment connection structure, profit
With simple and practicable tooling device, two kinds of Lengthened bolts and a kind of cushion block are designed, reaches the effect for moving in parallel motor, finally leads
Cause driving and driven gear to separate, significantly replace the cost of motor bearings, and the guarantee for traffic safety greatly improves.
