<p>A rotary drum humidifier has the rotor shaft connected to an electric motor by a corrosion resistant slip clutch assembly consisting of a telscoped relatively rotatable plastic clutch members interconnected in torque transmitting relation by ball elements seated in sockets on the inner member and projecting into the outer member where they are retained by a rubber annulus in a groove in the outer member, and when the torque exceeds a predetermined amount the balls are forced out of the sockets to interrupt torque transmission until the excess torque condition no longer prevails.</p> |
