ABSTRACT:
The disclosure pertains to a locking arrangement for a despin bearing assembly. The lock is produced by introducing liquid gallium into an annular gap having a V-shaped cross-section between shaft and housing of the assembly. The gallium is cooled to a temperature at which it becomes solid. Numerous depressions are milled into the inside sloping surface of the V-groove in the housing and as many holes are drilled through the mating annular protrusion on the shaft. These recesses become filled with gallium and provide many shear surfaces to accept loads between shaft and housing, thus avoiding yielding of metal at the ball-race interfaces in the bearings. Compression loads are also distributed over a broad surface of gallium throughout out the V-groove.
