Abstract
The utility model relates to a synchronous motor, in particular to a stator structure which is suitable for a deceleration type claw permanent-magnet synchronous motor, comprising an insulation framework, a coil curl, a rotor shaft and a plurality of gear shafts. The utility model is characterized in that certain positions on the end face of the insulation framework are caved and form a plurality of gear shaft holes. The bottom of the insulation framework is extended inward and forms a circular plane. The center position of the circular plane is caved and forms a rotor shaft hole. The gear shafts and the rotor shaft are respectively fixed on the gear shaft holes and the rotor shaft hole arranged on the insulation framework. The utility model has a simple and rational structure. Under the precondition of that the material cost is barely increased, the gear shafts and the rotor shaft are all arranged on the stator. Thus, the positional accuracy between the gear shafts and the rotor shaft is ensured, gears can run smoothly, and the noise is small.
Description
Technical field
The utility model relates to a kind of synchronous motor, relates in particular to a kind of stator structure of speed-reducing type claw poler form permanent magnet synchronous motor.
Background technology
At present, along with the extensive use of speed-reducing type claw poler form permanent magnet synchronous motor on household electrical appliance, especially in air-conditioning blade-rotating, electric heater and fan head swinging control, need the speed-reducing type claw poler form permanent magnet synchronous motor that a kind of noise is little, cost is low.The structure of existing speed-reducing type claw poler form permanent magnet synchronous motor as shown in Figure 1, complex root gear shaft that its armature spindle 3, a support 6 and support that is provided with by a cup-shaped casing 1 and casing is provided with 7, a stator 5, rotor that cylinder permanent magnet constitutes 4, one with cover 2 formations of the gear reduction 8 and an encapsulation motor of rotor 4 interlocks.Rotor 4 is journaled on the armature spindle 3 of casing central authorities, the cylindrical hole inner wall sleeve of stator 5 is stretched on the pawl utmost point 1a that establishes at casing, support is stretched in stator and is established pawl utmost point 6a, and packs in the casing 1 with the cylindrical hole inwall of stator 5 location, and reduction gearing 8 is packed on the gear shaft 7 and rotor 4 interlocks.By said structure as can be known, this kind motor can produce following shortcoming: 1) support 6 is located by stator 5 cylinder endoporus, stator 5 is located with casing pawl utmost point 1a, the rigging error accumulation of three workpiece, make gear shaft 7 and armature spindle 3 relative positions produce skew, cause the rotor 4 and the gear engagement position of reduction gearing 8 to change, when motor moves, produce big noise, influence product quality.2) gear shaft 7 on the support 6 and the armature spindle 3 on the casing 1 all adopt the riveted mode to fix, and its technology is punching on associated workpiece earlier, presses then.Comparatively speaking, the operation very complicated that seems.
Summary of the invention
The purpose of this utility model is to provide a kind of household electrical appliances to use, and locatees stator structure accurately reliable, speed-reducing type claw poler form permanent magnet synchronous motor low noise, easy for installation between armature spindle and the gear shaft.
Press the stator structure of a kind of speed-reducing type claw poler form permanent magnet synchronous motor of this purpose design, it comprises an insulation framework, a coil, an armature spindle and complex root gear shaft, its architectural feature be the ad-hoc location of insulation framework end face to recessed, form the plurality of pins axle hole; The insulation framework bottom surface extends internally, and forms a circular flat, recessed formation one rotor shaft hatch in circular flat centre; Gear shaft and armature spindle are separately fixed on the gear axis hole and rotor shaft hatch set on the insulation framework.
Technique scheme can also be done further improvement by following technical measures.
Gear axis hole and rotor shaft hatch that described stator forms are once obtained by injection molding.
The process that described armature spindle and gear shaft can take injection moulding embedding or interference to be pressed into is fixed.
Described gear shaft Kongzui adopts blind hole well, to increase the dielectric strength of stator.
The utility model is simple and reasonable, under the situation that does not increase material, finishes on stator the installing and fixing of gear shaft and armature spindle, and has substituted the gear shaft of riveting on the armature spindle of riveting on the casing and support.Cause the deviation between gear shaft and the armature spindle when having avoided the assembling of a plurality of workpiece, guaranteed positional precision between the diaxon, make that the synchronous machine gear operates steadily, noise is little.And rotor shaft hatch and gear axis hole adopt the method for injection mo(u)lding to obtain, and have reduced the operation of support, casing punching.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2-Fig. 4, this speed-reducing type claw poler form permanent magnet synchronous motor stator structure comprises an insulation framework, and this insulation framework is made up of insulation framework end face 15a, insulation framework bottom surface 15c and insulation framework cylindrical hole inwall successively.One coil 15e, an armature spindle 13 and complex root gear shaft 17, the ad-hoc location of insulation framework end face 15a form plurality of pins axle hole 15b, fixed gear shaft 17 to recessed; Insulation framework bottom surface 15c extends internally and forms a circular face, and its centre is recessed, forms the rotor shaft hatch 15d of a fixed rotor axle 13; Armature spindle 13 and gear shaft 17 are installed and fixed on stator 15, have substituted riveted armature spindle and gear shaft on casing and the support, so can guarantee to install the precision between the diaxon of back; On the circular face that insulation framework bottom surface 15c extends internally, be provided with plurality of holes, be used for stepping down when stator 15 is loaded on casing with casing pawl utmost point relevant position; Gear axis hole 15b and rotor shaft hatch 15d all add the acquisition in man-hour in the insulation framework injection moulding, have reduced manufacturing procedure; Gear shaft 15b is preferably blind hole, to strengthen stator insulation intensity; Gear shaft 17 and armature spindle 13 preferably adopt the injection moulding embedded mode to fix, and can improve the firmness that diaxon is installed.
Though the utility model is described with reference to above, do not break away from spirit and scope of the present utility model by the claims definition, still can make other modifications and variations.
