Description
Technical Field
The utility model relates to the field of motors, in particular to a motor rear end cover with an inclined surface seal.
Background
Generally, a linear seal is mainly adopted between the motor fan cover and the motor rear end cover, but the linear seal position of the motor rear end cover is too large or too small due to the influence of a processing technology, so that the problem of inconvenient installation exists when the linear seal position is too large, and the sealing effect cannot be achieved when the linear seal position is too small. If the sealing is plane-to-plane, the requirement on machining precision is not so high, and a novel motor rear end cover needs to be designed for the purpose.

In order to achieve the technical effects, the utility model adopts the technical scheme that: the utility model provides a sealed motor rear end cap in inclined plane, includes the rear end cap body, the coaxial shaping of rear end edge of rear end cap body has a protruding ring portion, the outside of protruding ring portion has set gradually backward along the axial is degressive guide face and the butt face of ladder, through inclined plane transitional coupling between guide face and the butt face, an O type circle groove has been seted up to inclined plane circumference.
Furthermore, the center of the rear end cover body is provided with a through shaft hole, and the front end of the through shaft hole is coaxially provided with a bearing hole.
Furthermore, the rear end of the rear end cover body is coaxially formed with a brake mounting plane, and the brake mounting plane is of an annular structure and is arranged between the convex ring part and the shaft penetrating hole.
Furthermore, at least three brake mounting threaded holes are circumferentially and uniformly distributed on the brake mounting plane.
Furthermore, at least four connecting lugs are uniformly distributed on the outer ring of the convex ring part, and the connecting lugs and the rear end cover body are integrally formed.
Furthermore, the front end edge of the rear end cover body is provided with a spigot which can be matched with the motor shell.
Compared with the prior art, the utility model has the beneficial effects that: the motor rear end cover with the inclined plane seal has the advantages that the sealing effect can be effectively guaranteed while the process precision difficulty is reduced through the improvement of the sealing position, the whole structure is simple, and the process manufacturing is convenient.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments, and it is apparent that the described embodiments are some, but not all embodiments of the present invention.
Drawings
FIG. 1 is a schematic structural view of a bevel sealed motor rear end cap of the present invention;
FIG. 2 is a back side schematic view of the rear cap body of the present invention;
FIG. 3 is an enlarged view of portion A of FIG. 1;
the reference numbers and corresponding designations in the drawings are: 1. the rear end cover comprises a rear end cover body, a shaft penetrating hole 1a, a bearing hole 1b, a convex ring part 2, a guide surface 21, an abutting surface 22, an inclined surface 23, an annular groove 2a.O, a brake mounting plane 3, a brake mounting threaded hole 3a, a connecting lug 4 and a spigot 5.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1 and fig. 3, the present embodiment provides a slope-sealed motor rear end cover, which includes a rear end cover body 1, a protruding ring portion 2 is coaxially formed at the rear end edge of the rear end cover body 1, a guide surface 21 and an abutting surface 22 which are stepped and decreased are sequentially arranged in the axial direction backward of the outer side of the protruding ring portion 2, the guide surface 21 and the abutting surface 22 are transitionally connected by a slope 23, and an O-ring groove 2a is circumferentially formed in the slope 23.
The rear end cover of the motor needs to be matched with a special motor fan cover (not shown in the figure) for use, the guide surface 21 can guide the motor fan cover sleeved into the rear end cover body 1 until the abutting surface 22 is tightly attached to the inner wall of the motor fan cover, an O-shaped ring is arranged in the O-shaped ring groove 2a on the inclined surface 23 in advance, and the inclined surface 23 and the O-shaped ring form reliable sealing together with the motor fan cover. Because the external diameter of collar portion 2 descends in proper order backward along the axial, consequently the installation is more convenient, and sealed effect is difficult for receiving the influence of collar portion 2 processing technology.
As shown in fig. 1 and 2, a shaft insertion hole 1a is provided in the center of the rear end cap body 1, and a bearing hole 1b is coaxially provided at the front end of the shaft insertion hole 1a. The shaft penetrating hole 1a is used for inserting a rotating shaft of the rotor, and the rotating shaft can be rotatably connected with the rear end cover body 1 through a bearing arranged in the bearing hole 1b.
