Electrically operated gate electromagnetic clutch.
Background technique
When electromagnetic clutch is mainly used in needing the operating condition of frequent starting in mechanical transmission course, it is responsible for connection and separation
Torque, while having both overload protection function.The achievable function of electromagnetic clutch has connection separation, speed change, positive and negative rotation, height
Frequency operation, positioning, indexing, fine motion etc..Electromagnetic clutch belongs to a kind of precision parts, and the precise degrees of installation directly affect
The performance guarantee transmitted to power, and then influence the reliability of complete machine.
Traditional electromagnetic clutch is three stator, rotor, armature component part-structure compositions, and stator passes through mounting flange
It is mounted directly, is fixed on the static positions such as bracket.Rotor is fixed in rotary shaft by flat key.Stator and rotor pass through conduct
The narrow air duct of magnetic circuit a part is combined, and forms magnetic pole.Armature unit and is turned by armature annular plate-like spring
It is sub opposite, and certain gap is kept, correctly it is combined.Stator interior has electromagnetic coil, and magnetic field is generated after energization, magnetization
Rotor generates magnetic field, attracts armature and generates combination, plate-shaped springs are deformed at this time, and the torque of driving side passes through plate-shaped springs
It is transmitted to slave end.In release, the power supply of electromagnetic coil is cut off, with the disappearance of electric current, magnetic field also disappears, due to plate bullet
The release action of spring, armature are begun to from mid-career student gap, so that torque disappears.
Traditional electromagnetic clutch is insufficient for opening electrically operated gate torque.
