CYLINDRICAL MAGNETIC CLUTCH Russian patent published in 2002 - IPC

FIELD: chemical, petrochemical and other industries. SUBSTANCE: invention relates to cylindrical magnetic clutches with permanent magnets. Proposed clutch has enveloping semiclutch and enveloped semiclutch enclosed in sealed cup. Each semiclutch is provided with magnetic circuit and radial permanent magnets uniformly spaced over circumference with alternation of poles. Tangential permanent magnets are installed between radial magnets on at least one on semiclutches. Invention makes it possible to use larger thickness of nonmagnetic clearance between rotating semiclutches and fixed cup at preset value of maximum torque. EFFECT: improved reliability of device, simplified assembling. 2 dwg
