Abstract
An assembly is provided for a piece of rotational equipment with an axis. This assembly includes a static structure, a bearing within a bore of the static structure, and a centering spring mounting the bearing to the static structure. The static structure is configured with the bore, a slot, a first slot surface and a second slot surface. The slot extends radially into the static structure from the bore. The slot extends axially within the static structure between the first slot surface and the second slot surface. The centering spring includes an annular hub and a mounting tab. The annular hub is within the bore. The mounting tab projects radially from the annular hub into the slot.
Claims21
An assembly for a piece of rotational equipment with an axis, comprising:
- a static structure configured with a bore, a slot, a first slot surface and a second slot surface, the slot extending radially into the static structure from the bore, and the slot extending axially within the static structure between the first slot surface and the second slot surface;
- a bearing within the bore;
- and
- a centering spring mounting the bearing to the static structure, the centering spring comprising an annular hub and a mounting tab, the annular hub within the bore, and the mounting tab projecting radially from the annular hub into the slot;
- wherein the centering spring comprises a first mounting portion, a second mounting portion and a spring portion extending axially between the first mounting portion and the second mounting portion;
- wherein the first mounting portion comprises the annular hub and the mounting tab;
- and
- wherein the bearing is within and mounted to the second mounting portion.
