An electric powered recirculating ball assembly comprising:
- a shaft having a plurality of sector teeth extending therefrom;
- an eccentric sleeve defining a bore containing a portion of the shaft, the eccentric sleeve comprising an upper sleeve segment and a lower sleeve segment that are separate components, the eccentric sleeve defining an opening that the sector teeth extend through;
- a male interlock feature on one of the upper sleeve segment and the lower sleeve segment;
- and
- a female interlock feature on the other of the upper sleeve segment and the lower sleeve segment, wherein the male interlock feature and the female interlock feature position the sleeve segments relative to each other.
An electric powered recirculating ball assembly comprising:
- a shaft having a plurality of sector teeth extending therefrom;
- an eccentric sleeve defining a bore containing a portion of the shaft, the eccentric sleeve comprising an upper sleeve segment and a lower sleeve segment that are separate components, the eccentric sleeve defining an opening that the sector teeth extend through
- a pin pocket defined along an outer surface of the upper sleeve segment;
- a cover disposed on an upper end of the upper sleeve segment and mechanically fastened to a sleeve housing;
- and
- a pin extending through the cover and into the pin pocket to adjust the position of the eccentric sleeve.
An electric powered recirculating ball assembly comprising:
- a shaft having a plurality of sector teeth extending therefrom;
- an eccentric sleeve defining a bore containing a portion of the shaft, the eccentric sleeve comprising an upper sleeve segment and a lower sleeve segment that are separate components, the eccentric sleeve defining an opening that the sector teeth extend through;
- and
- a one-directional clutch bearing located on an outer surface of the eccentric sleeve.
