Abstract
An internal support interface which provides vibration and acoustic isolation. A stationary shaft has a medial portion about which a rotatable member rotates. An end portion of the shaft has an annular base surface surrounding a stub shaft projection. A substantially planar housing member has a support post which extends from an annular interior surface in adjacent, non-contacting proximity to the stub shaft projection to form a gap therebetween. An annular damping member mutually contactingly surrounds the stub shaft projection and the support post while being compressed between the base surface of the shaft and the interior surface of the housing member.
Claims19
An internal support interface comprising:
- a stationary shaft comprising a medial portion about which a rotatable member rotates, and an end portion comprising an annular base surface surrounding a stub shaft projection;
- a substantially planar housing member comprising a support post extending from an interior surface, the support post in adjacent, non-contacting proximity to the stub shaft projection to form a gap therebetween;
- and
- an annular damping member which mutually contactingly surrounds the stub shaft projection and the support post while being compressed between the base surface of the shaft and the interior surface of the housing member.
An internal support interface comprising:
- a stationary shaft configured to support a rotatable member for rotation about a central axis;
- and
- first means for supporting a selected end of the shaft with respect to a housing member to provide relatively higher mechanical compliance in a direction along the central axis and relatively lower mechanical compliance in a direction along a plane normal to the central axis, wherein the first means comprises an annular damping member which mutually contactingly surrounds a stub shaft projection of the shaft and a support post extending from the housing member while being compressed between a base surface of the shaft and an interior surface of the housing member.
