Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in fig.1, the utility model embodiment offer is a kind of can to improve motor shaft smoothness and the electricity of fastness
Machine casing, the motor case include casing ontology 100.
Wherein, the 100 cylindrical structure of casing ontology.
As shown in fig.2, in the present embodiment, along in the axial direction of the casing ontology 100, the casing ontology 100 includes closing
End 120 and openend 110.And the edge of the openend 110 is provided with least one end cap bayonet socket 111, the shape of end cap bayonet socket 111
For rectangle, the end cap bayonet socket 111 constructs the breach 130 extended towards blind end 120, and the breach 130 is rectangular, the end cap card
Mouth 111 is mainly used in the installation of end cap, so as to improve the efficiency of end cap installation, ensures that the structure of casing ontology 100 and end cap is steady
It is qualitative.
As shown in fig.2, in the present embodiment, extend simultaneously in the direction away from openend 110 that is partially toward of blind end 120
Lug boss 121 is formed, it is necessary to illustrate, the part of blind end 120 herein refers to a part for blind end 120, certainly, its
Can also be separate part with blind end 120, the lug boss 121 offers the axis hole 122 worn for motor shaft, and
The axis hole 122 connects with the inside of casing ontology 100, and thus, the lug boss 121 generally comprises hollow cylindrical-shaped structure, by
In lug boss 121, so as to add the length of motor axle bearing, motor is improved relative to blind end 120 away from openend 110
The stability of axle so that the operation of motor shaft is more steady, because the length of axis hole 122 is extended so that the fixation of bearing
