Abstract:
An apparatus for supporting a steady bearing holder for a bearing in a coaxial rotational contact with the surface of a shaft having a longitudinal axis of rotation in a vessel, comprising:means for allowing axial movement of the bearing along the shaft in response to changes in radial dimensions of the vessel and for maintaining radial support of the shaft using a plurality of strut assemblies, each of said strut assemblies comprising a strut pair disposed radially around the shaft for supporting the bearing holder within the vessel; and means for resisting torsional movement about the shaft axis by the bearing due to friction between the bearing and shaft by locating the pairs of struts with an included angle between the struts of the pair so that the struts are disposed along a conical surface of rotation about the shaft axis.
