Operation principle：The size of magnetic field intensity is relevant with the corresponding area of conductor pin and magnet cylinder, and conductor pin stretches into magnet
During cylinder, conductor pin and magnet cylinder corresponding area are bigger, and magnetic field is bigger, and the moment of torsion of generation is bigger, and rotating speed of transmission shaft is faster；Lead
Scapus is stretched out during magnet cylinder, and conductor pin and magnet cylinder corresponding area are smaller, and magnetic field is smaller, and the moment of torsion of generation is smaller, transmission
Rotating speed is slower；When corresponding area is 0, i.e. conductor pin fully extended magnet cylinder, motor idle running, power transmission shaft does not turn.Use tune
Regulating device changes the size of the corresponding area of conductor pin and magnet cylinder, so as to realize speed-regulating function.
The present invention realizes the speed governing to coupler, Bu Huifa by adjusting the position of conductor pin extension entry/exit magnet cylinder
Magnetisation is leaked, and the distance between magnet cylinder and conductor pin can be adjusted indirectly by rotating the stubborn handle of hand, so as to realize speed governing.
Beneficial effect：The present invention is compared with prior art：Magnet cylinder of the present invention is set permanent magnet using tubular design
Magnet cylinder inner side is placed in, by design of the magnet cylinder for steel disk or iron pan, steel/iron has envelope magnetic action, will not occur magnetic leakage, leads to
Cross the supporting part being fixedly connected with power part and the cylinder adjusting gear rack being fixedly connected by fix bar with supporting part, cylinder regulation
Rack is arranged in the fixing groove on pedestal, and hand twists the cylindrical straight gear portion that handle is arranged at fixing groove side and cylinder adjusting gear rack
Adaptation connection realizes that rotating hand twists the size that handle is the corresponding area between adjustable magnet cylinder and conductor pin, so as to realize tune
Speed, while setting rotation stop groove and rotation stop plate to prevent cylinder adjusting gear rack from sliding in cylinder adjusting gear rack side, passes through butterfly screws
Prevent cylinder adjusting gear rack from sliding from now on, prevent cylinder adjusting gear rack from being rolled in groove by rotation stop plate, improve plant running
Stability, be imbued with practicality.
