Background technique
The rotor structure of existing kitchen ventilator brshless DC motor is SPM structure, i.e., magnetic links are surface-mount type, Surface Mount
Formula is easy to be knocked broken deficiency there are magnetic links.It in addition is then logical by Interference Fit Design between rotor and motor shaft
Cross press and squeezed and realize to be fixed together and transmit torque, the press of large-tonnage is not only needed in such assembling process and
And it is laborious when being separated between motor shaft and rotor；The axial float of rotor is completed by spring bearing, and branch is easy to cause
Support bearing damage or spring bearing fall off from end cap.
Summary of the invention
The present invention provides a kind of magnetic links to be not easy to be collided, is not necessarily to big pressure extrusion i.e. between rotor and motor shaft
It can link together and separate convenient soot motor, solve existing soot motor magnetic links and be easy to be knocked
And shaft need big pressure extrusion that can be assembled together, be assembled together after separate laborious problem.
The above technical problem is solved through the following technical scheme: a kind of soot motor, including from outside to inside successively
Motor casing, stator and the rotor of setting, the both ends of shell are equipped with end cap, and the rotor is equipped with motor shaft, and the two of the motor shaft
End is supported on the end cap by spring bearing, and the rotor includes rotor core and several magnetic links, which is characterized in that institute
It states rotor core and is equipped with several magnetic links installation through-holes extended along rotor axial, described one a pair of magnetic links is threaded through the magnetic
In steel disc installation through-hole, the both ends of the rotor core are equipped with several axially extending circumferentially distributed jacks along rotor, described
Motor shaft includes two semiaxis, and one end of the semiaxis is supported on the end cap by the spring bearing, the other end is equipped with
Several driving claws being threaded through in the jack correspondingly, are only transmitted by the driving claw between the rotor and semiaxis
Torque.By the way that magnetic links mounting hole is arranged in iron core, magnetic links are mounted in magnetic links mounting hole, so that iron core energy
It is enough that magnetic links are protected, prevent magnetic links to be knocked.Driving claw is cooperated to realize rotor and motor by design jack
The existing usual fixed form being pressed together by tight fit is changed in the connection of axis, so that assembly rotor and motor shaft
Shi Wuxu press is squeezed, and when assembly is easily laborsaving, and while separating is also laborsaving.
The magnetic links limited block at magnetic links both ends is connect the invention also includes gear.Magnetic links can be effectively prevent to generate axis
To play.
Preferably, the quantity of the jack and the quantity of the magnetic links installation through-hole are equal, the magnetic links limit
Block is connected to correspondingly on the driving claw, and the driving claw is equipped with block connecting hole, and the limited block screw thread connects
It connects in the block connecting hole.It is convenient when fixed magnetic links limited block.It is threadedly coupled, not only not easy to fall off, Er Qiean
Without separating motor shaft and rotor when magnetic links are unloaded in assembly and disassembly.
Preferably, being equipped with driving claw fastening structure, the driving claw fastening structure packet between the driving claw and rotor

Direction rotating magnetic steel piece limited block, magnetic links limited block drive trundle towards sliding in the second slide opening, trundle driving
Ejector pin stretches out the second slide opening and holds out against on the side wall of jack, so that driving claw be tightened together with rotor.Pressure limiting is separately driven
In pawl and rotor, then opposite direction rotating magnetic steel piece limited block, which makes transmission pin not, influences the contraction of ejector pin, outer drawing driving claw
When ejector pin can generate contraction and lose the effect of holding out against.
Preferably, the both ends of the magnetic links installation through-hole be respectively provided with it is a pair of for taking out magnetic links when grabbing of entering of finger
Take notch.Magnetic links are too loose when installing, and are easy to produce shaking, then rely on gravity that can not drop out when tight, and lifting is grabbed at this time
Conveniently put forth effort when taking notch, allowing to carry out crawl.
Preferably, two crawl notches in a pair of of crawl notch are distributed along the width direction of magnetic links.In magnetic links
It also can easily be grabbed when relatively thin.
Preferably, forming inflection point between the crawl notch and magnetic links installation through-hole.When crawl notch is along rotor
Axially through rotor frame mode when, the setting for grabbing notch will not provide the mobile space of magnetic links and not will lead to magnetic
Steel disc can move.
Preferably, between the rotor and end cap together by plane bearing support.Rotor can be effectively prevent to produce
Raw axial float.
Preferably, the plane bearing is supported on the driving claw.It is convenient when layout.
Preferably, the driving claw is equipped with the bearing limited block for keeping off and connecing in plane bearing radial outer end.It can be right
Plane is axially reliably fixed.
It is good to the protection effect of magnetic links that the present invention has an advantage that, magnetic links are not easy to be collided；It changes existing
Motor shaft and rotor connection type so that carry out operation without large-scale compress when being attached between rotor and motor shaft,
And it separates laborsaving when rotor and motor shaft.
