摘要： A higher efficiency roller screw system (10) that includes a nut body (12) designed to engage a threaded shaft (70). The nut body (12) includes a center bore (15) with closed, partial helical grooves (20) formed therein. Disposed inside the center bore (15) is a shaft (70) with open helical threads (72) formed thereon. A plurality of rollers (34) with non-helical grooves (35) formed thereon are also disposed inside the nut body’s center bore (15) and longitudinally alligned with the shaft (70) the grooves (35) on each roller (30) are designed to engage the grooves (20) on the nut body (12) and the threads on the shaft. The nut body (12) includes a cross-over region (40) where the trajectory of the internal grooves (20) extend radially outward and axially. When the roller’s grooves (35) contact the grooves (42) in the cross-over region (40), the rollers (34) are forced outward to maitain contact with the grooves (20) on the nut body (12) and are defleted axially. When they move outward, they disengage from the helical threads (72) on the shaft (70). As the nut body (12) continues to rotate, the grooves (35) on the rollers (34) maintain contact with the grooves (20) on the nut body (12) and re-engage the helical threads (72) on the shaft (70).

摘要： A hand tool with a mechanical linear drive mechanism coupled to a linear activated working implement. The drive mechanism includes a roller screw that includes a torque tube connected to a roller screw's nut body. The roller screw includes a fixed outer race, a rotating set of grooved rollers axially aligned inside the outer race, a cylindrical nut body located inside the set of grooved roller, a plurality of inner rollers axially aligned and inside the nut body, a threaded shaft axially aligned and inside the inner rollers, and a torque tube axially aligned inside the inner rollers. The torque tube is connected at one end to a multiple speed gear box which includes a primary motor coupled to a earner gear with three planet gears. Disposed around the planet gears is a ring gear. Coupled to the ring gear is a secondary motor which when activated causes the ring gear to rotate in the opposite direction of the planet gears. At least one sensor measures the rotation of an elastomeric ring and control activation of the secondary motor to change the operational speed of the tool.
