ABSTRACT:
An isolator mechanism is provided for use with a machinery housing and a rotatable shaft protruding through the housing. The isolator mechanism comprises a stator ring affixed to the housing and a rotor ring which is attached to the shaft and which nests within the stator. The stator and rotor are so shaped that the stator has a male cylindrical surface, and the rotor has a female cylindrical surface located radially outwardly of the stator male surface. A solid, circumferentially stretchable annular seal member is mounted on the rotor female surface and engages the stator male surface when the rotor and seal member are at rest. However, the deformable seal member is stretched circumferentially by centrifugal force out of engagement with the stator when the rotor and seal member are moving at operating speeds.
