Abstract
The utility model discloses a novel vertical direct-current motor structure, which mainly comprises a left end cover, a left shell, a stator, a right shell and a right end cover, wherein the shaft extension end of a motor is provided with a bearing assembly A; the non-shaft extension end of the motor is provided with a bearing assembly B; the stator is arranged between the left shell and the right shell; the left shell is fixedly connected with the left end cover through a bolt; and the right shell is fixedly connected with the right end cover through a bolt. The novel vertical direct-current motor structure is compact in structure, a bearing has high rigid strength, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of novel vertical DC motor structure.
Background technology
Along with the development of electric machine industry, the manufacturing technology of DC motor is also got over ripe, has formed the motor product seriation.Traditional DC motor structure comprises stator module, rotor assembly, rotating shaft and front and rear cover, this structural electromotor volume is bigger, and is not compact, and the total weight of current armature is quite big, when the vertical operation of motor, the heavy armature load is main on the bearing of non-shaft stretching end.
The content of utility model
The purpose of this utility model is to provide a kind of compact conformation, novel vertical DC motor structure that bearing rigidity is strong.
The utility model is the novel vertical DC motor structure of realizing like this, mainly comprises left end cap, left shell, stator, right shell body, right end cap, and it is characterized in that: motor shaft extension end is provided with bearing assembly A, and the motor non-shaft stretching end is provided with bearing assembly B; Be provided with stator between described left shell and the right shell body, described left shell and left end cap are connected and fixed by bolt, and described right shell body and right end cap are connected and fixed by bolt.
As optimization, described bearing assembly A is made up of upper bearing (metal) inner cap, upper bearing (metal) enclosing cover, two identical angular contact thrust bearings, disc, circlips for shaft; Described bearing assembly B is made up of lower bearing inner cap, lower bearing enclosing cover, disc, circlip for shaft and cylinder roller bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the bearing assembly A in the utility model;
Fig. 3 is the structural representation of the bearing assembly B in the utility model.
Among the figure 1, bearing assembly A, 2, left end cap, 3, left shell, 4, stator, 5, right shell body, 6, right end cap, 7, bearing assembly B.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The novel vertical DC motor structure mainly comprises left end cap 2, left shell 3, stator 4, right shell body 5, right end cap 6, it is characterized in that: motor shaft extension end is provided with bearing assembly A, and the motor non-shaft stretching end is provided with bearing assembly B; Be provided with stator 4 between described left shell 3 and the right shell body 5, described left shell 3 and left end cap 2 are connected and fixed by bolt, and described right shell body 5 and right end cap 6 are connected and fixed by bolt.
As optimization, described bearing assembly A1 is made up of upper bearing (metal) inner cap 11, upper bearing (metal) enclosing cover 12, two identical angular contact thrust bearings 13, disc 14, circlips for shaft 15; Described bearing assembly B7 is made up of lower bearing inner cap 71, lower bearing enclosing cover 72, disc 73, circlip for shaft 74 and cylinder roller bearing 75.
During concrete enforcement, the non-shaft stretching end of the utility model machine shaft adopts the SKF angular contact ball bearing, and adopts back-to-back mode to install, and bearing assembly B7 can bear the axial load from both direction like this, and the rigidity of assurance bearing is higher.
