<p>PURPOSE:To prevent vibration of an armature member of an electromagnetic clutch at high speed revolution by making the armature member in close engagement with a spline hub concentrically and slidably at the inner periphery part of the armature member or in the vicinity thereof. CONSTITUTION:In an electromagnetic clutch, a magnetic flux through a yoke 1 and a rotor 6 is formed by electrifying a coil 2 so that an armature ring 11 is attracted to a rotor 6 to be engaged with a frictional part 7, thereby transmitting rotation of a driving boss 9 to a driven spline hub 17. A-slide ring 19 having a cylindrical part 19a which makes close engagment with a spline 17a of the aforementioned hub 17 is provided and the armature ring 11 is made to come in close engagement with the external periphery of the cylindrical part 19a. An armature adapter 14 is fastened to the armature ring 11 with bolt-nuts 15 via said slide ring 19. Thereby, the armature ring 11 may be prevented from vibration at high speed revolution.</p> |
