Abstract
The invention relates to an outer rotor motor, comprising an outer rotor, a rotating shaft, a stator iron core, a first bearing, a second bearing and an end cover. The inner hole of the stator iron core is provided with a first bushing in a pressing manner; the first bearing and the second bearing have the same specification and are both arranged in the first bushing. The first bearing is arranged at the end of the first bushing close to one end of the outer rotor, and the second bearing and the first bearing are separated by a second bushing. A third bushing is clamped between one end of the rotary shaft close to one end of the inner cavity of the end cover and the second bearing by a gasket. The end of the rotary shaft close to one end of the outer rotor is provided a guiding part convenient to press and mount by the rotating shaft. The first bearing and the second bearing n are mounted in the same part so as to ensure the concentricity of two mounted bearings; during the operation of the motor, the two bearings are not easy to vibrate, the outer rotor is not easy to move up and down, thus, the motor of the outer rotor has low noise and less bounce.
Description
Technical field
The present invention relates to a kind of external rotor electric machine.
Background technology
Outer rotor blower fan has been widely used in the fields such as the room ventilation exhaust equipments such as hotel, large parking lot, building, office, mansion, air-conditioning unit, air cleaning system, smoke exhaust ventilator, apparatus cools.Outer rotor blower fan is structure and the pneumatic design that has adopted the rotation of the direct impeller of external rotor electric machine direct-connection transmission, the characteristics such as have that efficient height, noise are low, lightweight, compact conformation, installation and maintenance are convenient.
As shown in Figure 1, conventional external rotor electric machine is equipped with two bearings at present, one is installed in the bearing chamber of end cap bottom surface, another places in the bearing pedestal of the stator core other end, this bearing pedestal and iron core are not an integral body, but an independent part, bearing pedestal is fitted in the stator core end after the processing separately.Two bearings place respectively in two parts of processing separately, and the specification of bearing is not identical yet, therefore, are difficult to the concentricity of rear two bearings of control assembling.Can vibration in the bearing rotation process of different axles thereby drive external rotor and beat, beat is serious and noise arranged when causing vane rotary.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of external rotor electric machine is provided, two bearings of its inside are positioned at Same Part, and bearing is difficult for vibration in rotation process, and external rotor is difficult for beating.
The technical solution adopted for the present invention to solve the technical problems is: a kind of external rotor electric machine, have external rotor, rotating shaft, stator core, clutch shaft bearing, the second bearing and end cap, the endoporus of described stator core is pressed with the first sleeve pipe, clutch shaft bearing and the second bearing are the bearing of same size, and clutch shaft bearing and the second bearing are installed in the first sleeve pipe.
Described the first sleeve pipe covers the stator core endoporus and axially exceeds the stator core endoporus at the end near external rotor.
The end end that described clutch shaft bearing is installed in close external rotor in the first sleeve pipe also with between the external rotor is connected by stage clip.
Described the second bearing is installed in an end of close end cap in the first sleeve pipe, uses the second case off between the second bearing and the clutch shaft bearing.The second sleeve pipe fixed intervals clutch shaft bearing and the second bearing, clutch shaft bearing are difficult for waving in operation process, not easy glide.
Described end cap is installed in the second bearing outside, and described end cap (6), the first sleeve pipe (7), the second sleeve pipe (8) are three independently parts.Described rotating shaft penetrates from external rotor, passes clutch shaft bearing and the second bearing to the end cap inner chamber, with the pad card the 3rd sleeve pipe is arranged between an end end of the close end cap inner chamber of rotating shaft and the second bearing.The 3rd sleeve pipe is fixed the second bearing, and the second bearing is difficult for waving in operation process, not easy glide.
Described the first sleeve pipe, the second sleeve pipe, the 3rd sleeve pipe all adopt metal tube.
The end of close external rotor one end of described rotating shaft has is convenient to the leader that rotating shaft press-fits, and described leader is positioned at the outside of external rotor.
Further, described leader is the heat treatment seeker.
The invention has the beneficial effects as follows: clutch shaft bearing of the present invention and the second bearing adopt the bearing of same size, and be installed in Same Part namely in the first sleeve pipe, guaranteed to assemble the concentricity of latter two bearing, motor is in running, two bearings are difficult for vibration, and external rotor is difficult for beating, therefore, the external rotor electric machine noise is lower, is difficult for beating.
After increasing the heat treatment seeker in the rotating shaft, can guide press-fiting of rotating shaft, and when after external rotor electric machine fine finishining, checking, clamping parts when can be used as check, clamping when being convenient to check, and, the heat treatment seeker is because passed through heat treatment, namely drop so only need putt, process simple and conveniently, can not affect the profile of finished product external rotor electric machine.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention;
Wherein: 1. external rotor, 2. rotating shaft, 3. stator core, 4. clutch shaft bearing, 5. the second bearing, 6. end cap, 7. the first sleeve pipe, 8. the second sleeve pipe, 9. the 3rd sleeve pipe, 10. heat treatment seeker
Embodiment
