Filed: 1982-07-21
Abstract: PURPOSE:To make it possible to transfer forcibly scattered magnetic power into an operating gap in the titled clutch by a method wherein deflecting vanes are arranged near the operating gap. CONSTITUTION:When a magnetic flux is generated in the operating gap 27 by energizing an electromagnetic coil 3, the powder 28 is magnetized and the torque of an engine is transmitted to a drive member 20 due to the connecting force of the powder itself and the frictional force generating between the magnetized powder 28 and the operating surface of a clutch. When the clutch is in its unexicited condition, a drive member 1 rotates with the engine in the direction of the arrow while the deflecting vanes 33 are at a standstill together with the driven member 20. Further, the magnetized powder 28 rotating with the drive member 1 within gaps 29a and 29b runs against the deflecting vanes 33 and is transferred to the central part of the operating gap 27 by being guided along the inclined surfaces of the deflecting vanes. Accordingly, it is possible to gather the magnetized powder 28 in the operating gap 27 and to make the effective use of the powder for power transmission when the clutch is excited by energizing the electromagnetic coil 3.
