Abstract

Infinitely variable motion control (IVMC) using Transgear gear assemblies provides rotary motion control without any requirement for connecting or disconnecting gear meshes or use of a clutch. A bevel, miter, ring or spur gear Transgear gear assembly may be defined as a gear assembly having three or four of variables, input, output and control, assigned in a manner so as to provide, for example, one of accumulation of inputs and direction control. A four variable Transgear gear assembly may be one of a spur gear Transgear gear assembly having an additional ring gear surrounding a set of planetary gears or a bevel gear Transgear gear assembly having a double bevel gear, an outer bevel gear and a bevel gear meshing to the outer bevel gear sleeve surrounding an inner beveled gear and comprising three orthogonal carrier shafts. Rather than two sets of three variable Transgear gear assemblies connected in series or in parallel, a four variable Transgear gear assembly may provide, for example, a direction control function with just one gear assembly with two of the four variables assignable as control variables.
