Threaded spindle adjusting drive

摘要

A threaded spindle adjusting drive, e.g., a vehicle seat adjusting drive, includes a threaded spindle, a drive gear operably connected to the threaded spindle, and a bearing system for supporting axial and radial forces from the threaded spindle and/or the drive gear on a jacketed pipe. The bearing system has an axial bearing element abutting on at least one radially inwardly directed crimp of the jacketed pipe for supporting axial forces and a radial bearing ring abutting on the inner circumference of the jacketed pipe for supporting radial forces.

1. A threaded spindle adjusting drive, comprising:
a threaded spindle; a drive gear component operably connected to the threaded spindle; and a bearing system configured to support axial and radial forces from at least one of the threaded spindle and the drive gear component acting on a jacketed pipe, wherein the bearing system includes:
an axial bearing element, abutting on at least one radially inwardly directed crimp of the jacketed pipe, for supporting axial forces, the axial bearing element including a first axial-facing surface extending from the inner circumference of the jacketed pipe, anda radial bearing ring, separate from the drive gear component and abutting on the inner circumference of the jacketed pipe and at least a portion of the drive gear component, for supporting radial forces, the radial bearing ring including a second axial-facing surface extending from the inner circumference of the jacketed pipe, the second axial-facing surface of the radial bearing ring abutting the first axial-facing surface of the axial bearing element,wherein the axial bearing element and the radial bearing ring are separate components including different materials.
