ELECTROMAGNETIC CLUTCH Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: electromagnetic clutch has a housing with a coil and a friction unit. The friction unit has a stack of the flat magnetically conducting and flexible wavy disks including two axially arranged ring members interconnected with radial pieces. Each disk is made of a sine-like wave in the along-periphery direction. The number of waves on the inner and outer ring members is n₁ and n₂, respectively, with n₁≠ n₂. The radii of the waves are and , respectively, where x₁ and x₂ are the wavelengths over the periphery of the mean diameters of the ring members D₁ and D₂, and a₁ and a₂ are the heights of the wave measured from the axial plane of the disk. The amplitude of the waves in the radial direction is constant throughout the width of the ring members.

EFFECT: reduced coupling time.
