Abstract
The utility model discloses a rotor structure for mounting a fan. The rotor structure comprises a rotor and the fan which is sleeved on one end of the rotor, wherein the fan comprises a fan hub, fan blades and fixing feet; the fan blades are arranged on the outer circumference of the fan hub; and the fixing feet are arranged on an end face of the fan hub and are arranged between a rotor winding and slot wedge paper. The rotor structure is stable, is difficult to fall off and does not have influence on dynamic balance of the rotor and subsequent processing thereof.
Description
Technical field
The utility model relates to rotor, particularly relates to a kind of rotor structure that fan is installed.
Background technique
As everyone knows, rotor is the core component of motor, heat radiation then is the precondition of motor stabilizing operation, little for cooling micromachine (power is at 100w-150W) owing to volume, generally adopt in the rotor core and fan to be installed to solve, conventional fan mounting type is to stretch out four fastening foot on fan, be fixed in the narrow slot part of rotor between the rotor tooth, and by the fixing described fastening foot of the epoxy resin between the rotor tooth, such structure is very insecure, because fastening foot is exposed on the rotor core surface, and follow-up processing is had a significant impact.
The model utility content
It is a kind of firm that the purpose of this utility model is to provide, difficult drop-off and do not influence the rotor structure of the installation fan of rotor following process.
For achieving the above object, the utility model provides a kind of rotor structure that fan is installed, the fan that comprises rotor and be sheathed on described rotor one end, described fan comprises fan hub, be located at the fan blade on the described fan hub excircle and be located at fastening foot on the described fan hub end face, and described fastening foot is located between rotor winding and the slot wedge paper.
Described fastening foot tightly fits on the rotor winding outer surface.
Described fastening foot is processed with sphenoid surface with the free end surface that the rotor winding contacts.
Adopt the beneficial effect of the technical program to be: described fastening foot is located between rotor winding and the slot wedge paper, described fastening foot can tightly be fixed on the winding by described slot wedge paper, so described fan structure difficult drop-off, owing to be hidden in the rotor core groove, can not influence the dynamic balancing and the following process thereof of rotor, and not influence the planarization of rotor surface.
Description of drawings
Fig. 1 is a kind of schematic representation that is installed on epitrochanterian fan structure of the utility model;
Fig. 2 is a kind of plan view that is installed on the fan of epitrochanterian fan structure of the utility model.
Wherein: 1. fan hub 2. fan blade 3. fastening foot 4. rotors 41. rotor windings 42. slot wedge paper 43. rotor 5. commutators
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, shown in legend wherein, a kind of rotor structure that fan is installed, a fan that comprises a rotor 4 and be sheathed on described rotor one end, described fan comprises fan hub 1, be located at the fan blade 2 on described fan hub 1 excircle and be located at four fastening foot 3 on described fan hub 1 end face, and described fastening foot 3 is located between rotor winding 41 and the slot wedge paper 42.
Described fastening foot 3 tightly fits on rotor winding 41 outer surfaces.
Described fastening foot 3 is processed with sphenoid surface with the free end surface that rotor winding 41 contacts.
Described fan begins to install from an end of rotor commutator 5, on the rotor winding 41 in the described fan fastening foot 3 insertion rotor 43, the position of slot wedge paper 42 just had living space originally in the described rotor 43, and the rotor winding all has certain loosening property, therefore, described fastening foot 3 can be inserted in the described rotor winding 41 and tightly fit on the described rotor winding 41, and described slot wedge paper 42 also can play fixing effect to described fastening foot 3 in fixing described rotor winding 41 simultaneously.
Adopt the beneficial effect of the technical program to be: described fastening foot is located between rotor winding and the slot wedge paper, described fastening foot can tightly be fixed on the winding by described slot wedge paper, so described fan structure difficult drop-off, simultaneously can not influence the dynamic balancing and the following process thereof of rotor, and not influence the planarization of rotor surface.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (3)
1. rotor structure that fan is installed, the fan that comprises rotor and be sheathed on described rotor one end, described fan comprises fan hub, be located at the fan blade on the described fan hub excircle and be located at fastening foot on the described fan hub end face, it is characterized in that described fastening foot is located between rotor winding and the slot wedge paper.
2. the rotor structure of installation fan according to claim 1 is characterized in that, described fastening foot tightly fits on the rotor winding outer surface.
3. the rotor structure of installation fan according to claim 1 is characterized in that, described fastening foot is processed with sphenoid surface with the free end surface that the rotor winding contacts.
