1. A machine comprising:
- an outer housing receiving a drive shaft, at least one bearing housing supporting at least one bearing, said shaft being mounted within said at least one bearing, and said outer housing outward of said at least one bearing housing, at least one attachment member extending between said outer housing and said bearing housing;
a selected damping system including an elastomeric ring attached to a surface on one of said bearing housing and said outer housing, and a selectively moveable plate connected to the other of said outer housing and said bearing housing, and said plate being selectively moveable by an adjustment member from a position at which it engages said elastomeric ring and to a point at which it is spaced from said elastomeric ring;
said adjustment member being threaded, and being movable to achieve selective damping by turning said adjustment member in one direction to bring the plate to engage said elastomeric ring, and said adjustment member being moveable in an opposed direction to bring said plate to said point at which it is spaced from said elastomeric ring such that damping can be achieved or not utilized; and
wherein an actuator member includes a piston which is driven by a spring to move said plate towards said elastomeric ring, and said adjustment member moving said piston.

Abstract
A machine has an outer housing that receives a drive shaft. A bearing housing supports a bearing. The drive shaft is mounted within the bearing and the outer housing. Attachment members extend between the outer housing and the bearing housing. A selected damping includes an elastomeric ring attached to a surface of a bearing housing and an outer housing. A selectively moveable plate is connected to the outer housing and the bearing housing. The plate is selectively moveable from a position at which it engages the elastomeric ring to a point at which it is spaced from the elastomeric ring.

8. A machine comprising:
-
an outer housing receiving a drive shaft, at least one bearing housing supporting at least one bearing, said shaft being mounted within said at least one bearing, and said outer housing outward of said at least one bearing housing, at least one bolt extending between said outer housing and said bearing housing, a selected damping system including an elastomeric ring attached to a surface on one of said bearing housing and said outer housing, and a selectively moveable plate connected to the other of said outer housing and said bearing housing, and said plate being selectively moveable by an adjustment member from a position at which it engages said elastomeric ring and to a point at which it is spaced from said elastomeric ring, said adjustment member being threaded, and being movable to achieve selective damping by turning said adjustment member in one direction to bring the plate to engage said elastomeric ring, and said adjustment member being moveable in an opposed direction to bring said plate to said point at which it is spaced from said elastomeric ring such that damping can be achieved or not utilized, the component to be tested is a compressor rotor for a gas turbine engine, an actuator member includes a piston which is driven by a spring to move said plate towards said elastomeric ring, and said adjustment member moving said piston, wherein said adjustment member may be adjusted to cause said piston to move inwardly or outwardly of an actuator housing to move said plate portions towards and away from said elastomeric ring; and wherein said adjustment member is threadably mounted within an actuator member housing.
