Abstract
An armature comprises a rotor iron core (1), and is characterized in that the rotation shaft (2) of the rotor iron core (1) is connected with a worm rotation shaft (3) as a whole through a claw-type connector. In the utility model, the armature is divided into two parts, and is more convenient in assembly and has more deepened division of labor; and the motor and a speed reduction mechanism are assembled separately to obviate problem of abnormal noise and fault of the motor due to the poor concentricity resulting from the possible bending of the shaft with long length in the assembly process. In addition, the armature has the advantages of long service life, simple structure, low cost and is convenient in use.
Description
Technical field
The utility model relates to a kind of parts armature in the electric motor assembly.
Background technology
Rotor and worm drive shaft in the tradition armature all are same axises, and above-mentioned way is very high to this requirement of beating, processed complex, and also the long more perpendicularity of axle ensures that with crooked just being difficult to motor use a period of time axle is easy to bending, causes motor oscillating.
As the patent No. is the electric rotor that the Chinese patent (notification number is CN2783616) of CN200520011155.1 discloses a kind of electric tool, comprise coil windings and commutator, it is characterized in that: the syndeton of described commutator and described coil windings is: on described commutator, the end of commutator segment has holding tank, weld by of the end clamping of described holding tank the tap of described coil windings, the electric rotor of this utility model electric tool is suitable for a large amount of productions, its structure, make, assemble quick and convenient, but its rotating shaft is whole one, so there is aforesaid defective.
Similar problem also is present in the Chinese patent that the patent No. is CN200520011746.9 (notification number is CN2783609), and it provides a kind of electric rotor of improved electric tool, comprise main shaft and the iron core that is contained on the main shaft, it is characterized in that: on the outer surface of described iron core, have the balance groove.On described main shaft, impeller is housed.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of armature at the present situation of prior art, and it is convenient to the assembling between rotation axis and the rotating shaft, and rotating shaft can be changed, avoided the bending of power transmission shaft, made the electric rotor long service life, simple in structure, cheap, easy to use.
The utility model solves the problems of the technologies described above and the technical scheme that adopts is: a kind of armature, it includes rotor core, it is characterized in that: the rotating shaft of described rotor core and worm screw rotation axis are to link into an integrated entity by claw coupling.
Preferably, described claw coupling adopts the three-jaw connector.
As improvement, the rotating shaft that the rearward end of described three-jaw connector has special-shaped jack and rotor core is plugged on together, and there are three claws the front portion of three-jaw connector along circle distribution, accordingly, the rear section of worm screw rotation axis is furnished with three pawl seats, snaps in for claw.
Preferably, described special-shaped jack is mounting hole, triangle hole, quadrilateral hole or pentagon hole.
At last, the shaft length of described rotor core is 70mm, and the length of worm drive shaft is 32mm.
Compared with prior art, advantage of the present utility model is, traditional armature is divided into two, and assembles easier, divide the work refinement more, can accomplish that electric motor separates assembling with reducing gear, avoid bad in the assembling process, cause problems such as motor is suppressed extremely, abnormal sound because of the long flexible concentricity that causes of axle, and long service life, simple in structure, cheap, easy to use.
Description of drawings
Fig. 1 is a kind of structural perspective of the present utility model.
Figure number explanation: 1, rotor core, 2, rotating shaft, 3, the worm screw rotation axis, 4, the three-jaw connector, 5, special-shaped jack, 6, claw, 7, deck.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As schematically shown in Figure 1, a kind of armature, it includes rotor core 1, rotating shaft 2, three-jaw connector 4, worm screw rotation axis 3 critical pieces such as grade, rotor core 1 is that punching is overrided to form, be provided with rotating shaft 2 in the cavity of rotor core 1, rotor core 1 is provided with the element of winding, the circumferential surface of rotor core 1 is provided with compensating groove, its inventive point is that the rotating shaft 2 of described rotor core 1 and worm screw rotation axis 3 are to link into an integrated entity by claw coupling, and described claw coupling adopts three-jaw connector 4, described three-jaw connector 4 rearward end, have special-shaped jack 5, abnormity jack 5 shapes can adopt mounting hole, the triangle hole, quadrilateral hole or the like, present embodiment adopts mounting hole, the rotating shaft 2 of abnormity jack 5 and rotor core 1 is mapped and is plugged on together, there are three claws 6 front portion of three-pawl type connector 4 along circle distribution, accordingly, the rear section of worm screw rotation axis 3 is furnished with three pawl seats 7, also corresponding one by one, snap in connection for claw 6, rotating shaft 2 length of preferred described rotor core 1 are 70mm, worm drive shaft is 32mm, form the armature of an integral body, realizes integrated, make assemble simple and easy.
Concrete operations, earlier with rotating shaft 2 and three-pawl type connector 4 corresponding insertions, worm screw rotation axis 3 and three-pawl type connector 4 corresponding insertions form the armature of an integral body then, realize integratedly, and the time spent does not pull down one by one, and is simple in structure, cheap, easy to use.Like this, traditional armature is divided into two, assemble easier, divide the work refinement more, can accomplish that electric motor separates assembling with reducing gear, avoid bad in the assembling process, cause problems such as motor is suppressed extremely, abnormal sound because of the long flexible concentricity that causes of axle, and long service life, easy to use.
