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, have installing hole on the electric motor end cap usually, be used for fixing the stator of motor internal, common end cap and stator are connected together through a long bolt, but screw position and length do not fix, and that gives stator has fixedly brought very big inconvenience.
The utility model content
The technical problem that the utility model will solve provides a kind of convenience and the fixing electric motor end cap of stator.
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 front end housing and rear end cap; The center of said front end housing has the axis hole that supplies power shaft to pass, and has the inner ring installing hole around the said axis hole, and the quantity of said inner ring installing hole is four; Its diameter is 10mm, and the outer of front end housing has the outer ring installing hole, and the quantity of said outer ring installing hole is four; Its diameter is 11.5mm, and said rear end cap is provided with screw hole.
Compared with prior art, the advantage of the utility model is: the end cap body is provided with inner ring installing hole and outer ring installing hole, the convenient long bolt that diverse location and length are installed.
Further, the diameter of said axis hole is 35.9mm.
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 gross thickness of said front end housing and rear end cap is 33.5mm.
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 front end housing 1 and rear end cap 2; The center of said front end housing 1 has the axis hole 3 that supplies power shaft to pass, and has inner ring installing hole 4 around the said axis hole 3, and the quantity of said inner ring installing hole 4 is four; Its diameter is 10mm, and the outer of front end housing 1 has outer ring installing hole 5, and the quantity of said outer ring installing hole 5 is four; Its diameter is 11.5mm, and said rear end cap 2 is provided with screw hole 6.
In the present embodiment, the diameter of said axis hole 3 is 35.9mm; Said two adjacent inner coil installing holes 4 centers of circle are 45 ° to angle between the line in axis hole 3 centers of circle; The gross thickness of said front end housing 1 and rear end cap 2 is 33.5mm.
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.
