Description

Magnetic coupling double layers of rolling balls screw synchronous motion
Technical field
The utility model relates to a kind of magnetic coupling mechanism, and particularly a kind of magnetic coupling is with double layers of rolling balls screw synchronous motion
Background technique
Magnetic coupling is also to claim magnetic coupling, permanent magnetic transmission device, mainly is comprised of rotor, permanent magnetic disk and three parts of controller.Rotor is connected with motor shaft, and permanent magnetic disk is connected with the axle of working machine, and air clearance (being called air gap) is arranged between rotor and the permanent magnetic disk, and rotor and permanent magnetic disk do not have the mechanical connection of transmitting torque.Form soft (magnetic) between the machine operation machine and connect, realize the variation of working crankshaft moment of torsion, rotating speed by regulating air gap.And require the magnetic conductive disk synchronization motion of permanent magnetic disk both sides in technique, spacing between permanent magnetic disk and the magnetic conductive disk needs synchronous variation all the time, generally realize traditionally the synchronization motion of two magnetic conductive disks by linkage mechanism and pinion and rack, to realize output torque, the rotation speed change of magnetic coupling, it is very accurate that the problem that this structure exists is that synchronous effect is not, while structure relative complex, cost of production and maintenance cost are higher.Therefore need now a kind of novel magnetic coupler that can address the above problem synchronism mechanism of magnetic conductive disk.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structure, design ingenious, can the fine adjustment move distance, motion is smooth, rapidly, magnetic coupling with low cost is with double layers of rolling balls screw synchronous motion.
Technical solution of the present utility model is: a kind of magnetic coupling double layers of rolling balls screw synchronous motion, described synchronism mechanism is arranged between the first magnetic conductive disk 1 and the second magnetic conductive disk 2 symmetrically, it is characterized in that: described synchronism mechanism comprises that an end is fixed on the screw mandrel 4 on the first magnetic conductive disk 1, the other end of leading screw 4 matches is provided with inner nut 5, the inner ring of inner nut 5 cooperates with leading screw 4, the outer ring of inner nut 5 then is provided with threads of lead screw, be fixed on the large flange 3 inner nut 5 axial limitings, and inner nut 5 can rotate along self axis, and outside inner nut 5, also being socketed with the outer nut 6 that matches with its threads of lead screw, outer nut 6 is fixedly connected with the second magnetic conductive disk 2.
The utility model is compared with prior art, has following advantage:
The speed-regulating type magnetic Coupler synchronism mechanism of this kind of structural type, is swift in response at its fluent movements, can guarantee that two magnetic conductive disks can do take permanent magnetic disk as axle symmetrical action; Pass through the mechanism that linkage mechanism and pinion and rack are realized the synchronization motion of two magnetic conductive disks than traditional, it is with low cost, and is easy to maintenance, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the A section enlarged view of Fig. 1.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.Such as Fig. 1, shown in Figure 2: a kind of magnetic coupling double layers of rolling balls screw synchronous motion, described synchronism mechanism is two covers, and be arranged on symmetrically between the first magnetic conductive disk 1 and the second magnetic conductive disk 2, this synchronism mechanism comprises a leading screw 4, one end of this leading screw 4 is fixed on the first magnetic conductive disk 1, the other end then matches is provided with an inner nut 5, inner nut 5 can be when leading screw 4 rotates with respect to the axial motion of leading screw 4, but inner nut 5 large flange 3 axially on relatively fixing, outer ring at inner nut 5 then is provided with threads of lead screw, be socketed in the outer outer nut 6 of inner nut 5 with being provided with of matching of threads of lead screw, outer nut 6 is fixedly connected with the second magnetic conductive disk 2.
The utility model embodiment's magnetic coupling is as follows with the working procedure of double layers of rolling balls screw synchronous motion: when the first magnetic conductive disk 1 moves with respect to permanent magnetic disk under the effect of driving mechanism, drive the first magnetic conductive disk 1 and leading screw 4 actions that are fixedly connected with it, during leading screw 4 motion, inner nut 5 rotates with respect to leading screw 4, because inner nut 5 is fixed with large flange 3 in the axial direction, therefore being socketed in inner nut 5 outer outer nuts 6 this moment just can rotate at inner nut 5, drive the second magnetic conductive disk 2 with respect to inner nut 5 axial motions when rotating, this synchronism mechanism can realize that the first magnetic conductive disk 1 and the second magnetic conductive disk 2 do symmetrically relative movement, reaches the purpose that spacing between the first magnetic conductive disk 1 and the second magnetic conductive disk 2 and the permanent magnetic disk is regulated in adjusting simultaneously.
