Abstract
The invention relates to fan using inducing electric machinery rotating shaft structure. The inducing electric machinery includes shell, stator fixed on the shell, rotor set in the stator, rotating shaft rotated together with the rotor and supported by the bearing. The two ends of the rotating shaft are extended out of the shell; and each its outer circle face has one plane perforated by the screwed hole. It's only need one screw to fix the rotating shaft end, fan, and ventilating fan end while assembling which can save time and labor, reduce cost, and increase working efficiency.
Description
Technical field
The invention belongs to the fan electromotor field of air conditioner, the fan electromotor that particularly relates to a kind of window air conditioner is when assembling with fan, and is both convenient and swift, time saving and energy saving again, the revolute axes configuration of the inducing motor for fan of enhancing productivity.
Background technique
In general, motor is made up of stator and rotor two-part, and stator and rotor are made of the stacked iron core that forms of silicon steel core sheet respectively.Be cylindric by the stacked stator iron core that constitutes of lamination.Rotor is cylindric, and rotor is pressed on the running shaft and inserts in the cylinder cavity of stator iron core, has air gap to be separated by between rotor and the stator.Embed the winding of enameled cable coiled on the stator, staor winding outside source current by the time produce magnetic field.Rotor interacts with stator field when having electric current to pass through, and the generation electromagnetic torque also rotates in stator.
The household electric appliance that power is slightly little as window air conditioner, wall-hanging air conditioner etc., adopt single phase motor mostly.Be not with the enameled cable winding on the single phase motor rotor, the electric current in the rotor is not supplied with by external power, but is induced by stator field, and induction current and former magnetic field interaction make rotor rotation.
Stator comprises: by the winding of the enameled cable coiled that embeds in stacked stator iron core that constitutes of silicon steel core sheet and the stator shaft orientation groove;
Rotor comprises:. rotor iron core, cage type winding portion.Cage type winding portion has several stubs, end ring portion and counterweight portion.Rotor iron core is formed with axis hole in inside.
In the inner axis hole that forms of rotor iron core, be pressed into the running shaft that together rotates with rotor.
There is motor cabinet to be arranged on the chassis on the outdoor of window air conditioner, motor cabinet is being provided with motor, the running shaft of motor is outstanding to the indoor side and the outdoor of air conditioner separately, the axial rotary indoor side of one side is inner outstanding, on the outstanding running shaft in indoor side, fan is being set, fan be with indoor air be incorporated into carry out on the indoor heat converter again air being entered into after the heat exchange indoor.
On the outdoor running shaft of motor ventilation fan is being set, ventilation fan is introduced the air of outdoor, and the outdoor heat converter of air by the outdoor of air conditioner carried out heat exchange.
There is following problem in the running shaft of prior art single-phase inducing motor:
Its two ends shape of running shaft of technology as shown in Figure 1 and Figure 2 now, a plane 1 is respectively arranged on the outer peripheral surface of rotating shaft terminal, with the motor of this running shaft assembling with fan, ventilation fan assembling the time, axial restraint need be carried out with clip in rotating shaft terminal and fan, ventilation fan end, need the operator clip to be installed during assembling, waste time and energy with pliers.
Summary of the invention
The present invention provides a kind of when assembling with fan, both convenient and swift, time saving and energy saving again, the revolute axes configuration of the inducing motor for fan of enhancing productivity for solving the technical problem that exists in the prior art.
The technological scheme that the present invention takes for the technical problem that exists in the solution prior art is:
The revolute axes configuration of inducing motor for fan of the present invention, inducing motor comprises: housing, be fixed on the stator of being made up of stator iron core and staor winding on the housing; The rotor of being made up of rotor iron core and cage type winding portion is housed in the stator; In rotor shaft hatch, be pressed into the running shaft that together rotates with rotor; Running shaft is by the bearings that is fixed on the housing two side ends; Bearing has end bracket enclosed outward; The two ends of running shaft are elongated to outside the housing, and a plane is respectively arranged on the outer peripheral surface at two ends; The tapped hole that a perforation is arranged on its plane.
The present invention can also adopt following technical measures:
The tapped hole on the plane of described rotating shaft terminal is in same direction.
Advantage and good effect that the present invention has are:
The revolute axes configuration of inducing motor for fan of the present invention, with fan, ventilation fan assembling the time, steady job only need can be finished with a screw in rotation axle head and fan, ventilation fan end, and is time saving and energy saving with the motor of this running shaft assembling, reduce cost, improved working efficiency.

Fig. 2 is an A portion enlarged view;
Fig. 3 is the general assembly drawing of inducing motor for fan of the present invention;
Fig. 4 is the running shaft parts drawing of inducing motor for fan of the present invention;
Fig. 5 is a B portion enlarged view.
Embodiment
It is following that the present invention will be described in detail with reference to drawings and Examples.As shown in Figure 3, inducing motor for fan of the present invention comprises: housing 4, be fixed on the stator of being made up of stator iron core 2 and staor winding 3 on the housing; The rotor of being made up of rotor iron core 6 and cage type winding portion 5 is housed in the stator; In rotor shaft hatch, be pressed into the running shaft 8 that together rotates with rotor; Running shaft is supported by the bearing 7 that is fixed on the housing two side ends; Bearing has end cap 9 sealings outward; Motor connects lead 10 in addition.
The two ends of running shaft are elongated to outside the housing, and a plane is respectively arranged on the outer peripheral surface at two ends; The tapped hole 11 that a perforation is arranged on its plane.
The tapped hole on the plane of rotating shaft terminal is in same direction.
The use installation situation of the running shaft of inducing motor for fan of the present invention is as follows:
After being fixed to inducing motor on the motor cabinet, the rotating shaft terminal of motor stretches out to the forward and backward side of air conditioner, and the front end of running shaft inserts in the attachment hole of fan end, and insert in the attachment hole of ventilation fan end the running shaft rear end.The tapped hole of rotating shaft terminal all exposes beyond fan, ventilation fan end.At this moment again the screw corresponding with the tapped hole aperture is screwed in the tapped hole, can finishes the steady job of electric machine rotational axis and fan, ventilation fan.
When lead feeds electric current, machine operation, the running shaft rotation, running shaft drives fan, ventilation fan work.
