ABSTRACT:
A gear drive with variable gear ratio employs a set of idler gear shafts eccentrically mounted on rotating disks surrounding input and output drive shafts. Simple rotation of the disks engages and disengages, in sequence, different idler gear assemblies as mounted on the disks, with and from both the input and output drive shafts providing a simple changing of gear ratio and eliminating unnecessary turning of idler shafts not used for the direct transmission of power.
