Abstract
A linear wave gear drive has a car with oppsoite walls on which pluralities of apertures carrying reciprocating roller assemblies are arrayed. The car is located between inwardly-facing cam surfaces on a track and a belt housing outwardly-facing cam surfaces is passed through the car, with the assemblies contacting facing ones of the surfaces to move the car linearly in response to lineal movement through the car of the belt. The assemblies preferably have three rollers contrally mounted in axially-spaced locations for free, independent rotation about common shaft pins. The apertures are shaped to accommodate the pins in orientations perpendicular to the directions of movement of the belt and car, and parallel to the apertured car sides. Upper and lower rollers have identical larger diameters than central rollers to capture the belt edge in order to inhibit axial displacement of the pins. Assemblies are eliminated from a usual 'one more' or 'one less' wave gear construction to provide a stronger car.
