Abstract

678,403. Combined friction couplings and brakes. ROTAX, Ltd. March 7, 1951 [March 4, 1950], No. 6339/50. Class 80 (ii). [Also in Group XXXV] A motor drives an axially placed shaft through a spring loaded friction coupling which is adjusted by a rod k passing through a hole in the rotor shaft f, the loading spring j i being located in a bore provided in an electromagnetic brake disposed between the motor and the coupling. The spring j surrounds a spindle h which connects a member g of the coupling with the rotor shaft f. The electromagnetic brake consists of a fixed part n carrying the winding o and brake shoes p loaded by springs q. When the motor current is interrupted, the springs q urge the shoes outwardly to contact the inner periphery of a, rotary brake drum r secured to or formed on the coupling member.
