Abstract
A machine has first and second members. A bearing has an inner race mounted to the second member and an outer race rotatable relative to the inner race about an axis. A ring holds the outer race. A radial spring extends radially between the ring and the first member. First and second damper rings extending radially between the ring and the first member at first and second axial sides of the radial spring. First and second damping chambers are radially between an outer diameter surface portion of the respective damper rings and an inner diameter surface portion of the first member.

A machine comprising:
- a first member;
- a second member;
- a bearing having an inner race mounted to the second member and an outer race rotatable relative to the inner race about an axis;
- a ring holding the outer race;
- a radial spring extending radially between the ring and the first member;
- a first damper ring extending radially between the ring and the first member at a first axial side of the radial spring;
- a first damping chamber radially between an outer diameter surface portion of the first damper ring and an inner diameter surface portion of the first member;
- a second damper ring extending radially between the ring and the first member at a second axial side of the radial spring;
- and
- a second damping chamber radially between an outer diameter surface portion of the second damper ring and an inner diameter surface portion of the first member.
