Abstract: A method and apparatus are provided for smoothing the transition in rolling element/cam type nested speed converters and as motorized in a compact pancake package. More specifically, the apparatus for translating motion from a first to a second velocity includes drive devices made up of a conjugate pair of devices and a motion translating device mounted about a common axis. The pair of conjugate devices includes a first cam and a second cam. Each of the cams has at least one flank, the flank having a main drive segment formed according to a first function and at least one transition segment formed according to a second function. In one embodiment, the motion translating device, which is radially nested in between the two cams, has a plurality of radially extending slots, each slot containing one of a plurality of elements. The element is capable of traveling radially within its respective slot.

Abstract: Robust nested speed converter and bearing apparatus providing speed conversion function and bearing support function in a compact package for a range of applications.

Abstract: Methods and apparatus for translating angular velocity and rotary motive force of an input drive to angular velocity and rotary motive force of an output drive, by providing a pair of devices rotatable at, relative to or about a common axis, and translating means for transmitting angular velocity and rotary motive force of a first of the devices to angular velocity and rotary motive force of a second of the devices.

Abstract: Method and apparatus for rotary motion converting power transmission assembly with counter-rotating outputs on the same axis as the rotary input.

Abstract: Method and apparatus for achieving high torque and speed reduction in a compact and light-weight low parts-count speed converter apparatus featuring a floating ground element that both provides a moving ground to the first stage and acts as an input to a second stage, wherein both stages cooperatively drive the output.

Abstract: An in-line speed converter assembly for converting input rotation to output rotation with a minimum number of parts, the in-line speed converter having utility in a dryer as well as other devices which require in-line speed conversion with a minimum number of parts. The in-line speed converter having a conjugate pair of cam devices mounted on a common axis, an intermediate device nested between the cam devices in a common plane and having a plurality of circumferentially spaced-apart elements defining a plurality of radial slots therebetween.
