Abstract
The utility model relates to the technical field of motor, particularly relates to a kind of traction electric machine oil enveloping structure.This traction electric machine oil enveloping structure comprises electric motor end cap, bearing (ball) cover screw, bearing (ball) cover, oil ring, armature shaft and bearing, electric motor end cap is as on armature shaft, electric motor end cap connection bearing end cap, is provided with bearing between described electric motor end cap and bearing (ball) cover, and described oil ring is as in bearing (ball) cover.The structure of this traction electric machine oil enveloping structure is simple, by the setting of oil ring, plays lubrication, thus reduces the abrasion of eaves tile, only needs to carry out repair welding to bearing shell eaves tile or upgrade bearing shell, ruptures to prevent bearing (ball) cover screw.
Description
Technical field
The utility model relates to a kind of drill jig device, particularly relates to a kind of traction electric machine oil enveloping structure.
Background technology
In the prior art, the bearing (ball) cover complex structure of traction electric machine, particularly for fixed structure, traction electric machine bearing (ball) cover fixed screw ruptures, can make bearing (ball) cover and bearing outer ring, because losing fixing, outer altering occur, bearing ore deposit momentum is large, just likely causes traction electric machine bearing burnt dead, and very easily generator breaks.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of traction electric machine oil enveloping structure.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: this traction electric machine oil enveloping structure comprises electric motor end cap, bearing (ball) cover screw, bearing (ball) cover, oil ring, armature shaft and bearing, electric motor end cap is as on armature shaft, electric motor end cap connection bearing end cap, be provided with bearing between described electric motor end cap and bearing (ball) cover, described oil ring is as in bearing (ball) cover.
According to another embodiment of the present utility model, comprise described electric motor end cap further and be connected by bearing (ball) cover screw with bearing (ball) cover.
The beneficial effects of the utility model are: the structure of this traction electric machine oil enveloping structure is simple, by the setting of oil ring, play lubrication, thus reduce the abrasion of eaves tile, only need to carry out repair welding to bearing shell eaves tile or upgrade bearing shell, rupture to prevent bearing (ball) cover screw.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, electric motor end cap, 2, bearing (ball) cover screw, 3, bearing (ball) cover, 4, oil ring, 5, armature shaft, 6, bearing.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises electric motor end cap 1, bearing (ball) cover screw 2, bearing (ball) cover 3, oil ring 4, armature shaft 5 and bearing 6, electric motor end cap 1 is as on armature shaft 5, electric motor end cap 1 connection bearing end cap 3, be provided with bearing 6 between described electric motor end cap 1 and bearing (ball) cover 3, described oil ring 4 is as in bearing (ball) cover 3.Electric motor end cap 1 is connected by bearing (ball) cover screw 2 with bearing (ball) cover 3.
Motor bearings lid is combined by electric motor end cap 1 and bearing (ball) cover 3, and fixed by bearing (ball) cover screw 2, oil ring 4 as in bearing (ball) cover 3, when the large pinion rotation of gear box, because oil ring 4 is as in bearing (ball) cover 3, when pinion rotation, lubricating oil splash gets up, and falls core wheel and bearing shell eaves tile time, reduces the abrasion of eaves tile, only need to carry out repair welding to bearing shell eaves tile or upgrade bearing shell, rupture to prevent bearing (ball) cover screw 2.
Claims (2)
