It is right, and keep certain space, being correctly combined.Stator interior, which has, produces magnetic field, magnetized rotor after magnet coil, energization
Magnetic field is produced, attracts armature and produces combination, now plate-shaped springs are deformed, and the torque of driving side is transmitted by plate-shaped springs
To slave end.In release, the power supply of magnet coil is cut off, with the disappearance of electric current, magnetic field also disappears, due to plate-shaped springs
Release action, armature is begun to from mid-career student gap, so that torque disappears.Existing electromagnetic clutch has the disadvantage that：
Shortcoming one：Flat key, which coordinates, has clearance, and angular deviation is had during precision drive.
Shortcoming two：When having the shock loading to occur in transmission process, flat key easily loosens.
Utility model content
