Abstract
The invention provides a locomotive-mounted type gearbox which comprises a box body. An input shaft hole and an output shaft hole are formed in the box body. The box body is formed by detachably connecting a lower box main body, a first upper box main body and a second upper box main body. The first upper box main body and the second upper box main body are connected through a longitudinal combining face. The first upper box main body is connected with the lower box main body through a first transverse combining face. The second upper box main body is connected with the lower box main body through a second transverse combining face. The longitudinal combining face, the first transverse combining face and the second transverse combining face are all set in the radial direction of the output shaft hole. The input shaft hole is located in the first upper box main body. A flange is fixed to the first upper box main body and fixedly connected with a motor. When a driven gear is integral or separated, assembling is convenient and rapid; a driving gear and the driven gear can be conveniently disengaged; the whole box body can bear the meshing force of the driving gear and the driven gear and various loads from the traction motor due to the flange.

As shown in Figure 1 and Figure 2, the present invention provides a kind of railway locomotive bearing-type gear-box, and this gear-box includes casing, case
Input shaft bore 11 for wearing electric machine main shaft is had on body and for wearing the output shaft hole 12 of output shaft, casing is by first
Casing 1, the second upper box 2 and lower box 3 are detachably connected composition, and wherein, the first upper box 1 and the second upper box 2 pass through to indulge
Connect to faying face 30, the first upper box 1 is connected with lower box 3 by the first horizontal integration face 10, the second upper box 2 passes through the
Two horizontal integration faces 20 are connected with lower box 3, and the first horizontal integration face 10, the second horizontal integration face 20 and longitudinal faying face 30 are equal
It is radially arranged along output shaft hole 12；Input shaft bore 11 be located at the first upper box 1 on, and be fixed with this first upper box 1 for
The ring flange 4 carrying, ring flange 4 centre bore is located on electric machine main shaft and is fixedly connected with this motor.
Motor is as traction electric machine in the present embodiment；Concrete installation steps are as follows：
A) first, bearing, driving gear and other assembly are loaded in the first upper box 1, then the first upper box 1 is passed through
The unthreaded hole bolt of ring flange 4 is connected with traction electric machine；
B) secondly, it is on output shaft that driven gear is contained in axletree, if split gear, first gear core can be contained in car
On axle, then gear ring is fixed in gear core, this moment, when the connecting bolt of installation gear core and gear ring and alignment pin, space is not
It is restricted, be easy to operate, easy to assembly, quick, then miscellaneous part is arranged on axletree, that is, the complete wheel of formation is right, finally complete
Become traction electric machine and wheel to the connection with bolt；
c）Thirdly, the second upper box 2 is connected on the first upper box 1, that is, complete longitudinal faying face 30 bolt and
The connection of alignment pin；
d）Finally, lower box 3 is connected on the first upper box 1 and the second upper box 2, that is, completes the first horizontal integration face
