HYDRODYNAMIC PIVOTED PAD BEARING ASSEMBLY FOR A REACTOR COOLANT PUMP

摘要

The present invention relates to a hydrodynamic pivot pad bearing assembly for a reactor cooling pump, comprising: an annular member (50) attachable to a housing (32); A plurality of arcuate bearing segments 52 arranged so as to be connected between one end and the other in a circumferentially spaced interval to surround the shaft 22 and to provide bearing contact therewith; A plurality of pivot pins (54) extending radially between any one of said bearing segments (52) and said annular member (50); Means (68) for widely pivotally discharging each of the pivot pins (52) at an inner end (54A) of one of the bearing segments (52); Means (84) for installing each of the pivot pins (54) at an outer end of the annular member (50); The bearing assembly 48 is mounted on the annular member 50 to prevent inadvertent release of the pivot pin 54 at its inner end from the bearing segment 52 before it is installed on the shaft 22. A means for continuously holding the bearing segment (52).
