Abstract
A nuclear reactor coolant pump utilizes a pivoted pad bearing assembly to rotatably mount its shaft through the pump housing. The bearing assembly includes a plurality of arcuate bearing segments disposed end-to-end in circumferentially spaced relation for encompassing the shaft and providing bearing contact therewith, and a plurality of pivot pins each extending radially between an outer annular split ring attached to the pump housing and one of bearing segments. The pivot pins are mounted for universal pivotal movement at their inner ends with the respective bearing segments. The pivot pins at their outer ends are mounted to the annular ring for adjustable radial movement for changing the radial position of the pivot pins relative to annular ring and thereby of the bearing segments relative to the shaft. A plurality of locking cups are provided for coupling the pivot pins in locked relation the annular ring to fix the pivot pins in desired adjusted positions relative thereto.
