Drive p-m rotor 4 that driven shaft 3 is driven to rotate.
Wherein, the permanent magnet transmission governor can be tubular permanent magnet transmission governor or dish type permanent magnet transmission governor,
Or combination shape permanent magnet transmission governor.
The Fluid-transmission regulating module includes connecting with the p-m rotor 4 far from the side of the conductor rotor 2
What reciprocating round 7 and 7 male-female engagement of reciprocating round and the reciprocal ring 6 being relatively rotatable to each other and the driving reciprocal ring 6 moved
Fluid-transmission cylinder 5, wherein the Fluid-transmission cylinder 5 be piston type drive cylinder, the piston rod 14 of the Fluid-transmission cylinder 5 with it is described
The axis of driven shaft 3 is arranged in parallel, and is connected and fixed with the reciprocal ring 6.
Wherein, the reciprocating round 7 and the p-m rotor can in such a way that screw 8 as shown in Figure 1 is fixedly connected,
The connection type that can also be relatively rotatable to each other using pin shaft etc..It should be appreciated that the Fluid-transmission cylinder 5 is living for hollow Dual-barrel-shaped
When plug drive cylinder, not an only piston rod 14, specifically refers to that hollow Dual-barrel-shaped piston type drive cylinder includes extremely
Few two piston rods 14, and all piston rods 14 are flexible towards same direction, for Fig. 1 namely the work of piston type drive cylinder
The rod to the left of stopper rod 14.

Simplicity further eliminates rolling bearing in the prior art, can be used for high revolving speed, powerful operating condition, operates controlling party
Just, it is easy to accomplish stepless speed regulation and speed adjustable range is big；It only needs Fluid-transmission cylinder in conjunction with electric control part simultaneously, forms electro-hydraulic
Control or pneumoelectric control or gas-liquid control integral system, realize the mutual supplement with each other's advantages of various automatic controls；Be easily achieved standardization,
Seriation and generalization convenient for design, manufacture and promote and apply；Safety is good, and overload protection function may be implemented；Further,
Since structure is simple, reciprocal ring and reciprocating round are avoided in background technique forever using male-female engagement and the form that can relatively rotate
In magnet rotor rotation process the occurrence of mutual stuck between speed adjusting gear component.
As shown in Figure 1, the drive mechanism of 6 male-female engagement of the reciprocating round 7 and reciprocal ring can be, in the reciprocating round 7
Between be provided with the first groove, the centre of the reciprocal ring 6 is provided with and the second protrusion of first groove cooperation or described
Be provided with the first protrusion among reciprocating round 7, the centre of the reciprocal ring 6 be provided with it is the second of first male cooperation recessed
The axial dimension of slot, and either which kind of set-up mode, the protrusion is respectively less than the axial dimension of the groove.
Mating surface between the reciprocal ring 6 and the reciprocating round 7 is concave-convex matched groove and protrusion, groove and protrusion
Between be reserved with gap, i.e. the axial dimension of groove is bigger than the axial dimension of protrusion, namely concave-convex in reciprocal ring 6 and reciprocating round 7
There are a fixed gaps between the groove and protrusion of cooperation, in this way can by adjust gap avoid stable operation process further groove and
Phase mutual friction, abrasion between protrusion.If the groove and it is described protrusion between total axial gap be A, wherein the value of A be 1~
40mm, when the permanent magnet transmission governor adjusts the speed, the reciprocal ring is contacted with the reciprocating round, and the Fluid-transmission cylinder passes through institute
It states reciprocal annulus and moves the reciprocating round movement；The permanent magnet transmission governor completes speed regulation process and enters steady operational status, institute
State the direction mobile 0.5 that Fluid-transmission cylinder drives the reciprocal circumferential direction opposite with the reciprocal ring direction of motion described in speed regulation process again
~1/2A mm namely the Fluid-transmission cylinder drive the direction of the reciprocal circumferential contact surface far from reciprocal ring and reciprocating round
Mobile 0.5~1/2A mm, often more stable, reliable for actual motion, the line shaft between the groove and the protrusion
It can be preferably 5~25mm to gap A, the protrusion and groove of reciprocal ring and reciprocating round concave-convex fit structure in steady operational status
Between the axial spacings of two sides be 1/2A mm.The optional shape in male-female engagement face of the reciprocating round 7 and the reciprocal ring 6
For dove-tail, rectangle, V-arrangement or U-shaped and other shapes that can be adapted to.
As shown in Figure 1, the Fluid-transmission cylinder 5 of permanent magnet transmission governor provided by the invention preferably uses the hollow bitubular
Shape piston type drive cylinder, the hollow Dual-barrel-shaped piston type drive cylinder that is to say that the built-in annular of hollow Dual-barrel-shaped cylinder body cooperation is living
The piston cylinder formed is filled in, is connected with the identical piston rod 14 at least two rod directions, while preferred institute on annular piston
State hollow Dual-barrel-shaped piston type drive cylinder be coaxially set in the driven shaft 3 periphery namely hollow Dual-barrel-shaped piston type
The axis of drive cylinder is overlapped with the axis of driven shaft, and the inner peripheral wall of the hollow Dual-barrel-shaped cylinder body and the driven shaft 3
Evenly spaced radial 1~100mm between the wall surface of periphery, it is preferred that week of the piston rod 14 along the hollow Dual-barrel-shaped cylinder body
To uniformly.
It is readily appreciated that, there are appropriate between the inner peripheral wall of hollow Dual-barrel-shaped cylinder body and the periphery wall surface of the driven shaft 3
Radial clearance, be that of avoiding first driven shaft 3 during rotation with Fluid-transmission cylinder 5 generate friction, equipment is caused to damage
Evil；Secondly, preferably radially gap is 1~100mm, it can guarantee the radial direction of the hollow Dual-barrel-shaped cylinder body of Fluid-transmission cylinder 5 in this way
Size is unlikely to too big, reduces the sealing difficulty between hollow Dual-barrel-shaped cylinder body and annular piston, and save Fluid-transmission cylinder 5 and account for
Space.
Simultaneously because between the inner peripheral wall of the hollow Dual-barrel-shaped cylinder body and the periphery wall face of the driven shaft 3 are radially uniform
Away from 1~100mm, the Fluid-transmission cylinder 5 needs additional support component to support fixation.In practical applications, work as permanent magnet transmission
When governor is cooling using air, the Fluid-transmission cylinder 5 can be fixed by ad hoc bracket (not shown), when permanent magnetism passes
When dynamic governor is cooling using liquid, the shell that the Fluid-transmission cylinder 5 can be fixed on Control device of liquid cooling (does not show in figure
Out) on inner wall, to keep the relative position between the Fluid-transmission cylinder 5 and the driven shaft 3 invariable.
