Abstract
Method and apparatus for rotary motion converting power transmission assembly with counter-rotating outputs on the same axis as the rotary input.
Claims20
Apparatus for converting a rotary input to counter-rotating outputs, the apparatus comprising:
- said apparatus defining a source of rotary input mounted on an axis,
- an input part, a first output part, and a second output part, said parts mounted on said axis, with said input driven by said source for driving said outputs,
- one said output part defining an open center extending along said axis, one said output extending along said open center,
- said input part providing a rotary input rate in a first direction, said input part rotating in said first direction, said input part driving said first output part to provide a first output relative to said input rate in said first direction, said input part driving said second output part in a second direction counter to the first, and
- said input and output parts defining a conjugate pair of cam devices and a slotted device, wherein all three of said devices are located concentrically about said axis, said devices cooperating to rotate said second output in said second direction.

Method for driving counter-rotating concentric shafts, the steps comprising:
- defining a motor output shaft axis,
- providing an input part, a first output part, and a second output part,
- mounting said parts on said axis, in line with said motor shaft, with said input driven by said motor shaft and driving said outputs,
- providing one said output passing through the center of said other output, said input part rotating in a first direction and said input part driving said second output part in a second direction counter to said first direction, and
- providing said input part with a first device and further providing said second output part with a second device and a third device, said second and third devices cooperating with said first device to rotate said second output in said second direction.
