Roller screw thread drive for industrial application, has rollers with arrangement whose direction is different, so that quantity ratio of rollers that are arranged in different directions, for industrial application is constant or uniform

摘要

The drive has a turning element set between an elongated shaft (1) and a nut (2). The turning element defines a turning passage extending over a circumferential surface along the shaft, and is connected between two load paths in the elongated shaft and the nut to form a circulating path. The direction of arrangement of rollers is different, so that quantity ratio of the rollers that are arranged in two different directions, for an industrial application is constant or uniform. A nut module comprises the nut, a circulation element (3) and the turning element.
