Abstract
A power steering device includes a first gear provided on the first shaft, the first gear having a centerline axis, and a second gear operatively connected to the first gear. The second gear includes a rotational axis that is maintained substantially coplanar with the centerline axis. The power steering device further includes a compliant member operatively connected with the second gear. The compliant member allows rotational compliance of the second gear while avoiding axial and radial compliance.
Claims16
A power steering device comprising:
- a first gear having a centerline axis;
- a second gear operatively connected to the first gear, the second gear having a rotational axis, the rotational axis being maintained substantially coplanar with the centerline axis;
- and
- a compliant member operatively connected with the second gear, the compliant member allowing rotational compliance of the second gear while avoiding axial and radial compliance;
- a first drive element fixedly mounted to the second gear, the first drive element including an external bearing land and an inner hub, the inner hub receiving the compliant member;
- and
- a first bearing mounted to the external bearing land of the first drive element and a second bearing mounted in the inner hub of the first drive element, the first and second bearings enhancing alignment of the centerline axis and the rotational axis.

An apparatus comprising:
- a worm having a centerline axis;
- a worm gear operatively connected to the worm, the worm gear having a rotational axis, the rotational axis being maintained substantially coplanar with the centerline axis, the worm gear including a compliant member, the compliant member allowing rotational compliance of the worm gear while avoiding axial and radial compliance that would impact alignment between the rotational axis and centerline axis;
- a first drive element fixedly mounted to the worm gear, the first drive element receiving the compliant member;
- and
- a first bearing mounted to the external bearing land of the first drive element and a second bearing mounted in the inner hub of the first drive element, the first and second bearings enhancing alignment of the centerline axis and the rotational axis.
