Description
Technical field：
It the utility model is related to a kind of motor case.
Background technology：
Preferably to radiate to the rotor on motor and stator, a radiator fan is often set on the rotor of motor, and should
Fan is placed in the casing of motor, and when motor operates, radiator fan is rotated and radiated to casing internal；In the radiator structure
Radiator fan, stator and rotor be arranged in cavity, when replacing or repairing radiator fan, rotor need to integrally be taken out
From maintenance process could be completed, therefore the damage of rotor or stator can be caused unintentionally.
Therefore, it is necessory to be improved to the prior art to solve the deficiency of the prior art.
Utility model content：
The utility model is to provide a kind of motor case to solve the above-mentioned problems of the prior art.
There is technical solution used by the utility model：A kind of motor case, including the first housing, the second housing and end
Lid, the end cap are fixedly connected with the first housing, and the second housing is fixedly connected with end cap；
Axis hole is equipped with the center of the end cap, the inner wall of axis hole is equipped with bearing positioning cams；In the left end of end cap
Face is equipped with first rounded projections and second rounded projections coaxially arranged with axis hole, and the internal diameter of the first rounded projections
It is equal with the diameter of axis hole；
The right side of first housing is equipped with the positioning step portion being adapted with second rounded projections.
Further, some first thermal vias are equipped with the end cap and between first and second rounded projections.
Further, second housing is the structure of left end opening right end closing, is equipped with the second housing right side
Second heat emission hole.
The utility model has the advantages that：The utility model is simple in structure, and the stator installation cavity of casing point is with dissipating
Hot chamber is provided separately, easy to repair, and installation effect is good.
Brief description of the drawings：
Fig. 1 is the utility model sectional structure chart.
Fig. 2 is the structure chart of end cap in the utility model.
Fig. 3 is the connection structure diagram between end cap first shell body and end cap in the utility model.
Embodiment：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model discloses a kind of motor case, including the first housing 11,12 and of the second housing
End cap 13, end cap 13 are fixedly connected with the first housing 11, and the second housing 12 is fixedly connected with end cap 13.
Axis hole 130 is equipped with the center of end cap 13, the inner wall of axis hole 130 is equipped with bearing positioning cams 133；Holding
The left side of lid 13 is equipped with first rounded projections 131 and second rounded projections 132 coaxially arranged with axis hole 130, the
The internal diameter of one rounded projections 131 is equal with the diameter of axis hole 130.
The utility model for preferably by 13 location and installation of end cap on the first housing 11, in the right side of the first housing 11
It is equipped with the positioning step portion 111 being adapted with the second rounded projections 132.
Some first thermal vias 136 are equipped with end cap 13 and between first and second rounded projections.
The second housing 12 in the utility model is the structure of left end opening right end closing, on 12 right side of the second housing
Equipped with the second heat emission hole 122.
When mounted, the stator of motor and rotor are installed in the first housing 11, one end of rotor passes through bearings
In in the axis hole 130 of end cap 13, and rotor through the axis hole 130 and is stretched in the second housing 12, and radiator fan is placed in second shell
In body 12 and it is fixedly connected with the rotor.Motor case is divided into installation cavity and heat dissipation cavity by the utility model, and two cavitys are separately set
Put, when overhauling or replacing radiator fan, only need to dismantle the second housing 12.The first thermal vias 136 on end cap 13 with
The second heat emission hole 122 on second housing 12 is mutually communicated, and ensures the heat dissipation effect of the stator and rotor in the first housing 11,
In use, a filter screen can be added on the second heat emission hole 122 of the second housing 12, ensure dust-proof effect.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
