Description
Technical field
This utility model is related to a kind of bonder and in particular to magnetic is vortexed safety speed regulating bonder.
Background technology
At present, the magnetic eddy-current coupling on market divides plane driver and coaxial (or cylinder) type driver.
Plane driver, due to its architectural feature and operation principle, less demanding to the axiality of two axles during installation.
And for coaxial type driver, between main driven rotor, having certain air gap, air gap is less, magnets magnetic fields
Effectively utilizes are higher, but the requirement to installation quality is also higher, otherwise air gap is bigger, and the effectively utilizes of magnets magnetic fields are poorer, peace
Reload request is low.Therefore, during design, the moment of torsion of required driver can be obtained by adjusting the size of air gap radius.But in gas
In the case that gap is constant, also can increase moment of torsion by increasing the axial length (i.e. coupling area) of coupling magnet.
It is split type because principal and subordinate moves flange, the control of air gap is determined by the installation quality of field worker, and due to scene
Installer is unclear to product structure understanding or situations such as working sense of responsibility is not enough, lead to principal and subordinate move flange install centering less than
Position, thus lead to product cannot normally using or the defect such as life of product is short.
Utility model content
This utility model mainly solves in prior art principal and subordinate and moves flange and is split type and then is easily caused and looks for during installation
Just not in place, so lead to product cannot normally using or the problems such as life of product is short, a kind of magnetic solving the above problems is provided
Vortex safety speed regulating bonder.
This utility model is achieved through the following technical solutions:
Magnetic is vortexed safety speed regulating bonder, including motor connection axle, is arranged on the outer rotor in motor connection axle, turns with outer
The internal rotor that son matches, is arranged on the driven shaft on internal rotor, described motor connection axle is provided with and extends to driven axle position
Put the extension at place, this internal rotor is provided with the parallel-segment parallel with extension, between this parallel-segment and extension, pass through angle
Contact ball bearing connects.
This utility model passes through to optimize internal rotor, motor connection axle, and by the setting of angular contact ball bearing, effectively makes
Internal rotor and outer rotor connect as one in the case of not affecting to interact, both can guarantee that the topology requirement of itself moreover it is possible to
It is prevented effectively from Zhao's situation just not in place during installation.
In-site installation centering situation about leading to not in place and consequence are as follows:
1. parallel flange but misalign, flange secundly even contacts, and leads to air gap too small, another side air gap mistake on the contrary
Greatly, vortex occurs uneven, the phenomenon of monolateral stress, and then greatly impact using effect and life-span；
2. angle misaligns, and setting angle error is more than more than 2 °, or even contact or interference, and this phenomenon can lead to
Damage magnet or copper band；
3. flange axial gap is excessive or too small, affects magnet effectively utilizes area, and then leads to operation torque not enough, shadow
Ring effect.
Thus, by structure setting of the present utility model it is ensured that copper band and magnet on internal rotor and outer rotor when installing
Between air gap, greatly improve magnets magnetic fields effective rate of utilization, evade installation quality impact, exclusion install exist shakiness
Determine factor, effect is very notable.
Further, described extension is additionally provided with the gear displacement set threadeded with it, described outer rotor is arranged
There is the gear rotary shaft running through this outer rotor the rotation of driving gear displacement sleeve；Described angular contact ball bearing passes through gear displacement set

Connect, described driven flange is connected with internal rotor by arc safety pin.
In routine duties, equipment transmission unavoidable exist abnormal, when the situation of stuck or overload in working machine, that is, when
When load exceedes arc safety pin maximum permissible torque, arc safety pin is cut off, so that principal and subordinate moves flange and mutually disengages, main
Moved end (i.e. motor and magnetic coupling position) may continue to rotate freely, and protects motor not to be burned out and magnet demagnetization phenomenon.Fault
It is only necessary to more transducer set arc safety pin can return to normal production at once after exclusion, simple to operate, easy to maintenance, maintenance time
The advantageous feature such as short, greatly prolongs the service life of product.
Meanwhile, this utility model not only has above-mentioned Overload Protection by the way of the connection of arc safety pin and makees
With can also compensate for shafting deviation, reaching the effect of vibration and noise reducing, protecting against shock, and installation accuracy requires lower, installation operation
Easier.
Further, described internal rotor is fixed with the pin circle being socketed on driven flange, described arc safety pin is located at
Between pin circle and driven flange.
As one kind preferably specific implementation, described driven flange is provided with outer double wedge, described pin circle sets
It is equipped with interior double wedge, one end of this arc safety pin is connected on outer double wedge, and the relative other end is then connected on interior double wedge.
Further, the curved structure of described arc safety pin, and this arc safety pin adopts non-metallic material to constitute.Because
Arc safety pin is non-metallic material, thus protect principal and subordinate to move flange matrix not being worn, it is only necessary to change after long time running
Arc safety pin, with low cost, easy to maintenance.
Further, described arc safety pin is made up of nylon material.This material is not only only capable of meeting self-protection
Purpose, also has excellent toughness, self lubricity, wearability, chemical resistance, gas-premeable and oil resistivity, nontoxic etc.
Advantage, is very suitable for the requirement of this utility model arc safety pin.
