Abstract
The utility model discloses a direct current motor for the running gear of an electric locomotive. The direct current motor is provided with a front side end cap and a rear side end cap; and the outer wall of the front side end cap of a motor body is provided with an annular positioning boss. According to the utility model, through improving the structure and the shape of the front side end cap of the direct current motor, an installation and cooperation structure of a reduction gearbox and the motor body is changed, so installation and operation of the motor body is effectively simplified and coaxiality of an output shaft of the motor body and a main shaft of the reduction gearbox is effectively guaranteed; thus, product quality is improved, and vibration resistance of the electric locomotive in operation is enhanced.
Description
Technical field
The utility model belongs to electric locomotive structure-design technique field, is specifically related to a kind of direct current machine for the electric locomotive running gear.
Background technology
At present Coal Electricity locomotive running gear device has the following disadvantages aspect the connecting of motor and reduction box: motor is installed on the carriage, and carriage usefulness bolt is connected with reduction box.Motor adopts shaft coupling (two half a couplers, middle Elastic piece) with connecting of reduction box.The half a coupler mode of bolted, rely on and push transmitting torque between bolt and the bolt hole wall, the precision adjustment of the motor the when deficiency of this kind connecting mode maximum is installation and the axiality of reduction box, often adopt the mode of shimming to adjust axle high, enlarge the motor installing hole and adjust axiality etc., adjustment difficulty is high, and installation accuracy is difficult to assurance, and the shock resistance that electric locomotive is in operation is also relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of assembly technology and comparatively simplifies and the direct current machine that the location is used for the electric locomotive running gear comparatively accurately is installed.
The technical scheme that realizes the utility model purpose is: a kind of direct current machine for the electric locomotive running gear is provided with front side end cap and rear side end cap; The outer wall of described motor body front side end cap is provided with the circular orientation boss.
In the such scheme, the main shaft in the motor body stretches out the front side end cap as output shaft.
The utlity model has positive effect: (1) the utility model is by improving the planform of direct current machine front side end cap, thereby change the installation cooperation structure of reduction box and motor body, effectively simplify the fitting operation of motor body, and can effectively guarantee the axiality of motor body output shaft and reduction box inner main axis, improve product quality, also promoted the anti-seismic performance that electric locomotive is in operation.

The present embodiment is a kind of direct current machine for the electric locomotive running gear, sees Fig. 1 and Fig. 2, is provided with front side end cap 30 and rear side end cap 34; The outer wall of described motor body 3 front side end caps 30 is provided with circular orientation boss 32.
Main shaft in the described motor body stretches out front side end cap 20 as output shaft 31.
(application examples 1)
Fig. 3 and Fig. 4 have shown a kind of concrete application mode of the present utility model, and wherein Fig. 3 is a kind of application schematic diagram of the device out of shape that adopts direct current machine shown in Figure 1 and make; Fig. 4 is a kind of structural representation of device out of shape shown in Figure 3 after removing motor body.
Should use-case be a kind of electric locomotive running gear that adopts above-described embodiment 1 to make, see Fig. 3 and Fig. 4, comprise the framework 1 that is provided with travelling wheel 11 and be arranged on reduction box 2 and motor body 3 on the framework 1; The output shaft 31 of described motor body 3 stretches in the reduction box 2; Described reduction box 2 is provided with location notch 21 at the side with motor body 3 adjacency; Described motor body 3 is being provided with the positioning boss 32 that matches with this location notch 21 with the outer wall of the front side end cap 30 of reduction box 2 adjacency; Described positioning boss 32 is inserted in the location notch 21.
Described location notch 21 be shaped as circle, the periphery wall of described positioning boss 32 also is circular, the external diameter of positioning boss described in the present embodiment 32 is identical with the internal diameter of location notch 21.
Described framework 1 is provided with bracing frame 12, and the diapire 33 of described motor body 3 is fixed on this bracing frame 12.
From should finding out by use-case, by improving the planform of direct current machine front side end cap, change the installation cooperation structure of reduction box and motor body, can effectively simplify the fitting operation of motor body, and can effectively guarantee the axiality of motor body output shaft and reduction box inner main axis, improve product quality, also promoted the anti-seismic performance that electric locomotive is in operation.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
