Patent ES-451373-A1 (ES)
Title: Variable speed drive mechanism
IPC: F16H15/28
Filed: 1976-09-09
Abstract: A drive mechanism is described that provides a speed ratio that is infinitely variable between predetermined limits. Coaxial driving and driven shafts carry discs formed with frusto-conical friction surfaces arranged face-to-face with control spheres in frictional engagement with these surfaces and equidistantly distributed round the discs. Each control sphere has an annular groove in which rolling elements of a rolling bearing run. Each bearing is mounted on one face of a control segment formed on the opposite face with an arcuate surface which rolls on the base of a groove in an adjusting ring, concentric with the shafts, when the adjusting ring undergoes axial movement. Each control surface has a spherical journal that projects into a bore in the adjusting ring so as to ensure such rolling action when the ring is adjusted to vary the speed ratio, which variation results from the consequent variation of the angular dispositions of the control segments, whose arcuate surfaces are centered on the centers of the control spheres. The adjusting ring may be outside the assemblies of control spheres, rolling bearings and segments, or inside these assemblies. Two means are described whereby the torque reaction of the transmission maintains the control spheres in good frictional contact with the discs.
