Description
Technical field
The utility model relates to a kind of motor, in particular to the motor of a kind of outer rotating motor on model sports aircraft turns
Son.
Background technique
The motor that the model of an airplane uses is outer rotating motor, and the stator of the outer rotating motor is fixed on the fuselage of aircraft, outside
The rotor of rotating motor is fixedly connected by connecting screw with the rotor of aircraft, and rotor covers on stator, and the coil of such motor is set
It sets on stator, magnetic pole is arranged on rotor, when passing through electric current in coil, covers the rotor on stator and rotates and drive rotor
Rotation, thus, make the liftoff flight of aircraft.
In general, outer rotating motor is made of rotor, stator and the shaft being connected between rotor and stator, rotor by skull and
Housing combination is constituted, and the magnetic pole is fixed in shell, and shell is fixed in the inside of skull, and (side towards stator is interior, court
Be to the side of rotor it is outer, similarly hereinafter), the outside of skull is arranged in the connecting screw.
Skull 2 in the prior art is made by aluminum alloy materials, and the connecting screw 21 is solid hopkinson bar, with skull 2 one
Body shapes and is located at the outside of central substrate 24 of skull 2, is equipped with axis hole 25 on the inside of central substrate 24, the axis hole 25 be blind hole and
It is coaxially set with connecting screw 21, the outer end of the shaft 4 is placed in the axis hole 25, and axis hole 25 is located in central substrate 24
Top be equipped with machine-processed rice screw hole, it is corresponding, in the shaft 4 opposite with machine-processed rice screw hole be equipped with flat position 8, using machine-processed rice screw
7 screw in machine-processed rice screw holes and tight against on the flat position 8 (shown in Figure 4), can be fixedly connected on shaft 4 and skull 2
Together, achieve the purpose that prevent shaft 4 from loosening with skull 2.
But above structure exists following insufficient:
1) need to do flat position 8 in shaft 4, for axis when being pressed into the axis hole 25, the flat position 8 in shaft 4 needs to be aligned institute
It is pressed into after the machine-processed rice screw hole stated, increases the difficulty that shaft 4 enters in axis hole 25.
2) due to 2 small volume of skull, when to machine-processed rice screw hole machined (i.e. the aperture and tapping), because of operating space
Limitation, difficulty increases, to cause processing cost substantial increase.
3) it after shaft 4 is pressed into axis hole 25, needs the gluing on machine-processed rice screw 7 and then is tightened on the machine-processed rice screw 7
In machine-processed rice screw hole, assembly man-hour is caused to increase.
4) since the model of an airplane is that aircraft usually can lead to its accidental falling because of some reasons during flight
Or collided with other objects, and the connecting screw 21 being connected in the prior art with rotor is with 2 integral structure of skull and by aluminium alloy
Material it is made (skull 2 is manufactured using light aluminum alloy, one being the overall weight in order to mitigate the aircraft, two come be in order to
Reduce the load when rotated of rotor 1), when there is accidental falling or collision phenomenon, connecting screw 21 easily split off and with
The separation of skull 2 causes entire aircraft damage.
5) due to the flat position 8 in shaft 4, the setting of the machine-processed rice screw hole on skull 2 and machine-processed rice screw 7, cause entirely to turn
The Mass Distribution of son 1 is planar uneven in the institute of rotor 1, and it is bigger than normal to will cause dynamic balancing value, thus, influence flight reappearance.
