Fig. 1 is the utility model magnetic control resistance gauge front view;
Fig. 2 is the utility model magnetic control resistance gauge resistance maximum rating A-A cutaway view;
Fig. 3 is the utility model magnetic control resistance gauge resistance minimum state A-A cutaway view;
Fig. 4 is a partly cutaway view of the utility model magnetic control resistance gauge;
The specific embodiment:
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment: see that Fig. 1 comprises drag devices and drag regulator to magnetic control resistance gauge shown in Figure 4, this drag devices is the reluctance force device, and it comprises magnet 3, rotary flyweights 1 and fixed disk 5.The rotary flyweights 1 of magnetic control resistance gauge is the cast iron flywheel, and this cast iron flywheel constitutes a metallic closed ring, but cutting magnetic line produces resistance in rotary course.In order to increase reluctance force, compressed conductive ring 2 at the disk medial surface of cast iron flywheel, relative with magnet 3.Gapped between magnet 3 and the conductive ring 2.This conductive ring 2 can be copper band or aluminium circle.The cast iron flywheel is the disk of hollow, and fixed disk 5 is positioned at the hollow disc of cast iron flywheel, can move axially, and magnet 3 is fixed on the side face of fixed disk.Magnet 3 is a plurality of circular arc magnet and is evenly arranged on the side face of fixed disk 5.Drag regulator links to each other with fixed disk 5, is used to regulate the relative position of fixed disk 5 and rotary flyweights 1, and and then changes the position of magnet 3.The commentaries on classics scooter of cast iron flywheel is very high, and the reluctance force effect is fairly good.The motional inertia of cast iron flywheel is big, and the reluctance force effect also can be better.
Certainly, also magnet 3 can be fixed on the disk medial surface of rotary flyweights 1, and conductive ring 2 is fixed on fixed disk 5 side faces, by the magnetic line of force of the magnet in conductive ring 2 cutting movements, can produce resistance too like this.Simultaneously, fixed disk 5 also can be made with metal, makes the itself also can cutting magnetic line.
Control for ease of installation, the magnetic control resistance gauge also comprises flywheel stator 9, fixed disk 5 is fixed on the axle center 7 with rotary flyweights 1, flywheel stator 9 is fixed in the two ends in axle center 7, and drag regulator is a steel cable side draw mechanism, and it comprises first spring 6 and steel cable 8, first spring 6 places between flywheel stator 9 and the fixed disk 5, steel cable 8 is two, and there is projection its end, in the groove that is loaded on fixed disk 5 both sides of projection horizontal symmetrical.One side of steel cable 8 has stop screw 11,12, and one of them screw 11 vertically passes the hole on the flywheel stator 9, and another screw 12 vertically passes the hole on the fixed disk 5, is fixed on the previous screw 11, at outer second spring 10 that is with of stop screw 11,12.Adopt steel cable side draw mechanism, but make fixed disk 5 move axially stepless speed regulation, and uniform and stable.
In order to strengthen magnetic field intensity, also be provided with iron ring 4, fixed disk 5 and iron ring 4 injection one, it is solid and reliable that fixed disk 5 is combined with iron ring 4, and magnet 3 places on the outer peripheral face of iron ring 4.Experiment showed, that magnet 3 is arranged on the iron ring 4, the magnetic field of magnet surface is increased, played the effect that strengthens resistance.
For the moving range that makes fixed disk 5 is bigger, guarantee that simultaneously fixed disk 5 resets smoothly to the left.To shown in Figure 4, first spring 6 is a volute spring as Fig. 2.
Described magnetic control resistance gauge has following characteristics:
Noncontact, nothing are worn and torn, are as good as sound, energy free loss and meet environmental protection standard;
The linear stability of characteristics of resistance, adjusting are exerted oneself little and balanced, can realize stepless adjustment, are particularly suitable for the environment of rotation at a high speed;
Simple in structure, mechanical strength there is not specific (special) requirements, reluctance force maximum when resetting, degree of safety height.The resistance size adjusting method of embodiment is: flywheel is only done the circumferencial direction rotation, the magnet 3 that is arranged on the fixed disk 5 axially moves with fixed disk 5, magnet 3 changes with conductive ring 2 and the corresponding area of cast iron flywheel, thereby reaches the purpose of regulating reluctance force.Magnet 3 is more little with conductive ring 2 gaps, and reluctance force is also big more.
The reluctance force Principles of Regulation of embodiment are: owing to cutting magnetic line in rotary course, thereby produce reluctance force, hinder the motion of rotary flyweights 1.Because the size and the magnetic field intensity of reluctance force are proportional, in diverse location place magnetic field intensity difference, the resistance that cutting magnetic line produces is also just different, thereby plays the effect of step-less adjustment reluctance force.
