Magnetic coupling
First Claim
1. A magnetic transmission device by which torque can be transmitted without contact of the driving and driven elements comprising a first stationary magnetic pole ring, a second stationary magnetic pole ring circumferentially surrounding and radially spaced from said first magnetic pole ring, a first rotatable torque transmitting ring connected to one of said elements and having an even number of axially aligned bars of highly magnetic material causing a magnetic connection between said first pole ring and said second pole ring, and a second rotatable torque transmitting ring connected to the other of said elements with the first torque ring circumferentially surrounding and being radially spaced from said second torque ring and with said first and second torque transmitting rings separating said magnetic rings in the radial direction.
