Abstract
A bearing retainer for mounting for a bearing in an X-ray tube, the X-ray tube having a rotating anode supported on an anode shaft held within a hollow anode stem, the retainer being slidably fitted into a hollow anode stem to hold one bearing coaxially with the anode shaft and to permit axial motion of the bearing so held, where the sliding surface of the bearing retainer is coated with titanium carbide, and wherein the bearing retainer includes a bearing flange not coated with titanium carbide which may be swaged around the outer race of the bearing to hold the bearing.
Claims3
In an X-ray tube having a hollow anode stem having an inner surface and containing an anode shaft supported by one or more bearings having inner and outer races, a bearing retainer comprising:
- a retainer substrate means for slidably fitting coaxially within the hollow anode stem;
- a bearing sleeve means coaxially affixed to the retainer substrate for holding an outer race of a bearing fixedly and coaxially with respect to the retainer substrate;
- a coating means applied to the outer circumference of the retainer substrate for lubricating the sliding of the retainer means.
