Abstract

870,914. Variable-speed gearing; shaft couplings; universal joints. PERBURY ENGINEERING Ltd., and PERRY, F. G. DE B. Sept. 9, 1957 [Sept. 11, 1956], No. 27819/56. Class 80 (2). In an infinitely variable speed gear having first, 10, and second, 11, coaxial torus discs connected by rollers 13 precessionally rocked to vary the transmission ratio and in which the pressure between the discs and the rollers is increased with the load on the input shaft 1 of the gear. a flexible coupling connects the input shaft 1 with the means for generating the frictional engaging pressure. The means for generating the engaging pressure in a Hayes type gear comprises cam surfaces 8, 9 and tapered rollers 15, as described in Specification 870,913. The end of the input shaft 1 is formed as a drum 6 having axially-extending dogs 7 engaging dogs on a coaxial ring 31 to which is welded a ring 32 having offset parallel faces. The periphery of the ring 32 is riveted to a plane coaxial disc 34. The driving-cam 8 is similarly attached to a disc 36 through dogs 41 and a ring 38. The discs 34, 36 are connected by a ring 35 of synthetic rubber bonded thereto, to provide a flexible coupling. In modifications the rings 32 38 are flanged inwardly for connection by a pleated spring welded to the flanges, or are flanged outwardly and connected by rubber rings bonded to the flanges and to an enveloping cylinder. In other modifications, the drum 6 and driving cam 8 are formed with radial slots engaging radially disposed spring strips retained by a cover member, alternatively one spring carrier may be dogged to the cam 8 and the springs arranged at an angle to the axis of the gear unit.
