Planet rolling screw thread drive, has threaded spindle provided with screw thread, guide grooves connected with nut-side grooves, feed grooves connected with screw thread, and nut elastically deformable in axial direction

摘要

The drive has a nut (2) provided with nut-side grooves (9) at its inner circumference, where the nut-side grooves are arranged transverse to nut axles. A threaded spindle (1) is provided with a screw thread (16), and feed grooves (13) and guide grooves (14, 15) are provided at a periphery-side of a planet (3). The guide grooves are in connection with the nut-side grooves. The feed grooves are in connection with the screw thread, and the nut is elastically deformable in axial direction, where the nut is manufactured from metal sheet by reshaping.
