Abstract:
A device for curing a photosetting substance in an assembly, such as a pivot assembly or a disk drive motor, having a housing with an interior and an opening to the interior, a shaft having an axis mounted inside the interior of the housing such tat one of the shaft and the housing is rotatable relative to the other, wherein the photosetting substance is located at interfaces between the housing and the shaft at opposite axial ends of the assembly, comprising:a UV light source for emitting UV light; a conduit having proximal and distal ends for concentrating light from the light source at the proximal end and directing the light to the distal end and into the opening in the housing to cure the photosetting substance located inside the assembly; and a beam splitter mounted to the distal end in the conduit for distributing the light inside the housing, wherein the beam splitter is a prism-shaped mirror that divides an original beam of the light into multiple beams that are essentially orthogonal to the original beam and move in substantially opposite directions.
