Abstract
To provided a pivot bearing assembly that can be easily assembled without deformation, featuring lower amount of outgas and thermal compensation of bond strength. Further, with the pivot bearing assembly, between a bearing inner ring and a shaft, between a bearing outer ring and a housing are slidingly fitted, bonded and secured to each other with an ultraviolet curing type anaerobic adhesive having a high vitrification temperature, respectively.
Claims5
A pivot bearing assembly comprising:
- a bearing inner ring, a shaft, a bearing outer ring, and a housing, wherein the bearing inner ring and the shaft, the bearing outer ring and the housing are bonded and secured to each other with an ultraviolet curing type anaerobic adhesive having a high vitrification temperature, respectively.
A method of manufacturing a pivot bearing assembly, comprising steps of;
- applying or injecting an ultraviolet curing type anaerobic adhesive to predetermined spots between a bearing inner ring and a shaft, between a bearing outer ring and a housing,
- sustaining a curing time under extremely vacuumed ambience, and
- curing an overflowed portion of the adhesive by irradiating ultraviolet rays under atmosphere so as to further cure the overflowed portion of the adhesive.
