Abstract

The utility model discloses an end cover of a motor, which comprises an end cover body, wherein, four lugs are arranged on the end cover body and respectively provided with screw holes; vents are formed on the side wall of the cover end body; a shaft hole allowing an input shaft to penetrate is formed at the center of a cover plate of the end cover body; the cover plate adopts a space keeping structure; four inner ring mounting holes are formed at the periphery of the shaft hole on the cover plate; and the diameter of each inner ring mounting hole is 10mm. The end cover has the advantages that the heat in a bearing chamber can be radiated out through the vents, and the cover plate adopts the space keeping structure so as to reduce both the material consumption and the weight of the end cover body, further reduce processing difficulty and accordingly reduce the manufacturing cost.

Description

A kind of electric motor end cap

Technical field

The utility model belongs to the technical field of motor cover body, relates in particular to a kind of electric motor end cap.

Background technology

Electric motor end cap is that a kind of the installation with motor case cooperates, and is used for fixing the motor main parts size of the stator and the rotor of motor internal.In the prior art, the cover plate of electric motor end cap is generally the plane, and concavo-convex variation is very little, because cover sheet thickness is consistent, the material of its consumption is more, and weight is heavier, thereby causes manufacturing cost higher.

The utility model content

The technical problem that the utility model will solve provides a kind of electric motor end cap easy to manufacture, lower-cost.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of electric motor end cap comprises the end cap body; Said end cap body is provided with four journal stirrups, is equipped with screw hole on the said journal stirrup, and the sidewall of said end cap body is provided with ventilation hole; The center of end cap body cover plate has the axis hole that supplies power shaft to pass, and said cover plate is the empty avoiding structure, has the inner ring installing hole around the said cover plate upper shaft hole; The quantity of said inner ring installing hole is four, and its diameter is 10mm.

Compared with prior art, the advantage of the utility model is: ventilation hole can distribute the heat of bearing chamber the inside, and the electric motor end cap cover plate is the empty avoiding structure; Reduced the material that consumes; Alleviated the weight of end cap body, reduced the difficulty of processing, thereby reduced manufacturing cost.

Further, the diameter of said axis hole is 35mm.

Further, the said two adjacent inner coil installing hole centers of circle are 45 ° to angle between the line in the axis hole center of circle.

Further, the height of said end cap body is 80mm.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:

Fig. 1 is the structural representation of a kind of embodiment of the utility model electric motor end cap.

Embodiment

As shown in Figure 1, a kind of electric motor end cap of the utility model comprises end cap body 1; Said end cap body 1 is provided with four journal stirrups 2, is equipped with screw hole 3 on the said journal stirrup 2, and the sidewall of said end cap body 1 is provided with ventilation hole 4; The center of end cap body 1 cover plate has the axis hole 5 that supplies power shaft to pass, and said cover plate is the empty avoiding structure, has inner ring installing hole 6 around the said cover plate upper shaft hole 5; The quantity of said inner ring installing hole 6 is four, and its diameter is 10mm.

In the present embodiment, the diameter of said axis hole 5 is 35mm; Said two adjacent inner coil installing holes 6 centers of circle are 45 ° to angle between the line in axis hole 5 centers of circle; The height of said end cap body 1 is 80mm.

For a person skilled in the art; Under the prerequisite that does not break away from the utility model structure; Can also make some distortion and improvement, these also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
