Abstract
An exemplary center housing rotating assembly includes a turbine wheel (260); a compressor wheel (240); a center housing (210) that includes a through bore (215), extending from a compressor end to a turbine end along a bore axis, and a recess (217), adjacent the bore, in a plane orthogonal to the bore axis; a bearing assembly (230) positioned in the bore that includes a keyway (233); and an anti-rotation component (280) seated in the recess and at least partially in the keyway to restrict rotation of the bearing assembly in the bore. Various other exemplary devices, systems, methods, etc., are also disclosed.
Claims13
A center housing rotating assembly comprising:
- a turbine wheel (260);
- a compressor wheel (240);
- a center housing (210) that comprises
- a through bore (215), extending from a compressor end to a turbine end along a bore axis, and
- a recess (217, 297), adjacent the bore, in a plane orthogonal to the bore axis;
- a bearing assembly (230, 291) positioned in the bore that comprises an inner race (234), rolling elements (236), and an outer race (232, 292) with a keyway (233, 293);
- and
- an anti-rotation component (280, 296) seated in the recess (217, 297) and at least partially in the keyway (233, 293) to restrict rotation of the outer race (232, 292) of the bearing assembly (230, 291) in the through bore (215),
- wherein the anti-rotation component (280, 296) comprises dimensions in the plane orthogonal to the bore axis,
- wherein the recess (217, 297) comprises dimensions in the plane orthogonal to the bore axis that exceed the dimensions of the anti-rotation component (280, 296) to determine an amount of rotation of the outer race (232, 292) in the through bore (215) by points of contact that restrict rotation of the outer race (232, 292) for clockwise rotation of the anti-rotation component (280, 296) and by other points of contact that restrict rotation of the outer race (232, 292) for counter-clockwise rotation of the anti-rotation component (280, 296), and wherein the anti-rotation component does not receive axial thrust forces from an axial face of the outer race.
