Abstract
An apparatus for an axially displaced flexural bearing support assembly including a unitary or monolithic bearing support base member having a bearing receiving tube supported by a first and second generally parallel arrangement of flexural spoke members to control bearing pre-load due to axial differential expansion while eliminating radial displacement of the spindle or shaft supported within the tube. The spoke members of each arrangement include a plurality of spoke members arranged in parallel planes generally perpendicular to the axis of a spindle insertable within and supported within the tube by means of bearings. In the preferred embodiment, there are three spokes for each set in each plane, with the spokes being equiangularly displaced. To facilitate casting as a monolithic unit, one set of spokes is offset from the other by an angle half the angle between spokes, that is sixty degrees, and further, the width of the spokes is such that no spoke portion overlies any other spoke portion, as viewed from a line along the axis. The assembly also includes a generally hollow housing portion having a second bearing receiving opening, the housing and the base support member being …
