ABSTRACT:
A fluid-powered device having a body with interior helical grooves, an output shaft with exterior helical grooves, a plurality of rollers having circumferential grooves, and an axially receiprocating piston sleeve mounted within the body and retaining the rollers in fixed axial and circumferential position relative to the piston sleeve during powered operation of the device. The rollers are retained by the sleeve portion of the piston sleeve in circumferentially distributed arrangement between the grooved body and shaft surface portion with at least a first plurality of the rollers in seated engagement with the grooved body and at least a second plurality of the rollers in seated engagement with the grooved output shaft for transmitting force between the body, output shaft and piston sleeve. In alternative embodiments, the rollers include a single set of rollers mounted on spindles carried by the piston sleeve, two sets of axially separated rollers positioned in windows of the piston sleeve and mounted on spindles therein, and two sets of radially staggered rollers in both nested and spaced-apart arrangements. The rollers may be an integral unit or comprised of a plurality of rollers disk. The spindles are axially adjustable to eliminate backlash.
