2 and 4 is magnetic piece fixed disk, and 3 is gear drive grooved cam speed adjusting gear, and 6 is to turn round at a high speed conductive contact, and 7 is fixed for motor
Son, 8 is rotor, and 9 is synchronous disk, and 10 is expansion set, power transmission shaft centered by 11, and 19 is support, and 23 is flange shaft sleeve.
In two big series Y type grooved cam electric speed regulation disc type magnetic coupler, all of inductive disks is made up of caging bolt connection
Outer rotor, all of magnetic piece fixed disk is connected on center driving axle, and inner rotor motor external gear drive grooved cam speed governing
Mechanism forms internal rotor together.Turn round at a high speed slip ring and the motor stator synchronous axial system of conductive contact, geo-stationary, at a high speed revolution
The brush of conductive contact and support keep geo-stationary.The brush of revolution conductive contact connects external power source at a high speed.Two-way switch control
System enters the sense of current of motor, thus changes motor internal rotor and turn to the relative of center driving axle.Motor internal rotor drives tooth
Wheel shaft rotates, and is then driven the solid fixed-axis rotation of roller by gear drive, thus driven roller moves along the curved grooves of grooved cam,
Owing to roller is shaftless to displacement, so grooved cam will be subjected to displacement vertically, magnetic piece fixed disk is driven to slide along center driving axle,
Thus change the distance (magnetic field coupling gap) between magnetic piece fixed disk and inductive disks, to reach purpose (the magnetic field coupling of variable speed energy saving
Close the change in gap, the change of magnetic coupling inner and outer rotors slip, the namely change of input and output rotating speed will be caused).
Fig. 2, Fig. 3 show inner rotor motor external gear drive grooved cam speed adjusting gear, and spacing back-up ring 3-13 is used for ensureing
Synchronizing bar 3-11 will not occur axial float, and 3-12 is fine setting spring, and 3-15 is grooved cam, and 3-14 is that roller fixes axle,
3-16 is roller, and 3-3 is the retainer of synchronizing bar and leading screw.For motor stator, (outer surface has groove for drawing power supply to label 7
Line), 8 is rotor, and synchronous disk 9 ensures that with expansion set 10 motor stator 7 is (relative quiet with center driving axle 11 synchronous axial system
Only), rotor 8 and gear shaft 3-7 holding screw 13 are fixed together, synchronous axial system.3-6 is gear, and roller
Fixing axle interference fit.Grooved cam assembly (is fixed axle 3-14, roller 3-16 etc. by grooved cam 3-15, roller to form)
Cam groove can also be placed on part 3-14, then roller 3-16 is fixed on part 3-15.
Fig. 4 show magnetic piece fixed disk 2, has clearly given expression to powerdriven mode semiaxis, also show dividing of magnetic piece
Cloth situation.
Fig. 5 show magnetic piece fixed disk 4, and it can not directly and center driving axle 11 carries out power transmission, but can slide axially,
Magnetic piece fixed disk 4 relies on three synchronizing bar 3-11 to carry out driving coupling, also show the distribution situation of magnetic piece.
Fig. 6 show revolution conductive contact at a high speed, uses modular construction, and the quantity of slip ring determines as required, shown in figure
Being three slip rings (can be six or the most individual), connect three of the wires, adapter ring 6-2, overcoat 6-7, overcoat 6-1 adopt
With electrically insulating material, 6-5 is brush, and 6-4 is slip ring (being embedded in overcoat 6-1), and 6-8 (is used for putting down for fine setting spring
