Abstract
752,818. Powder clutches. SOC. MEDITERRANEENNE MINIERE METALLURGIQUE ET COMMERCIALE. March 5, 1954 [March 9, 1953], No. 6530/54. Class 80(2) A centrifugal powder coupling between two shafts 1, 2, either one of which may be the driving shaft, comprises a two-part casing 3 of lenticular shape integral with or connected to the shaft 1, said casing containing a quantity of metallic powder and enclosing a rotor 9 which is carried by the shaft 2 and is of annular or disc form. having a plurality of radial undulations 9a or other deformations around its periphery, the amplitude of the undulations increasing outwardly of the rotor so that as the speed of rotation increases the powder is compacted into a number of approximately triangular prisms 15 adjacent the crests of the undulations and readily becomes decompressed as rotation ceases. A ball race 7 is provided between the shaft 2 and casing 3. The metallic powder is introduced through a stopper in the casing and is prevented from escaping by felt rings 14. It is stated that the coupling may act as a torque-limiting device, since excessive torque will break down the prisms 15. In a modification, a central partition divides the casing into two equal parts, each of which encloses a ring-like rotor, both rings being connected to the shaft 2. Specification 697,557 is referred to.
