Abstract
A wave spring is disclosed herein that creates hysteresis between two components. The wave spring includes an annular body having a wave-shaped profile, and a plurality of axially extending fingers extending from the annular body. The wave spring is dimensioned to be received in a space between at least two axially opposed hub components.
Claims20
A wave spring comprising:
- an annular body having a wave-shaped profile that defines a first axial height (h1) in an uninstalled state, wherein the annular body includes at least one trough and at least one crest that is axially and circumferentially spaced from the at least one trough, and wherein the first axial height (h1) is defined between the at least one trough and the at least one crest, and
- a plurality of axially extending fingers extending from a radially inner edge of the annular body, the plurality of axially extending fingers having an axial extent (d) that is greater than the first axial height (h1), and the wave spring being dimensioned to be received in a space between at least two axially opposed hub components;
- wherein the wave spring, in an installed state, has a second axial height (h2) extending from the at least one trough to the at least one crest, the second axial height (h2) being less than the first axial height (h1).
A hub assembly comprising:
- a wave spring including an annular body having a wave-shaped profile that defines a first axial height (h1) in an uninstalled state, and a plurality of axially extending fingers extending from a radially inner edge of the annular body, the plurality of axially extending fingers having an axial extent (d) that is greater than the first axial height (h1), wherein the annular body includes at least one trough and at least one crest that is axially and circumferentially spaced from the at least one trough, and wherein the first axial height (h1) is defined between the at least one trough and the at least one crest;
- a cover plate and a flange hub both arranged on a first axial side of the wave spring, an opening being defined between the cover plate and the flange hub and the opening being dimensioned to receive at least one of the plurality of axially extending fingers, and
- a turbine hub arranged on a second axial side of the wave spring,
- such that a predetermined gap is defined between the cover plate and the turbine hub and the wave spring is arranged within the predetermined gap.
