Abstract:
A vibration isolation apparatus, comprising:a first bearing support;a second bearing support spaced a distance from said first bearing support;a first bearing structure attached to said first bearing support;a second bearing structure pivotally attached and freely rotatable relative to said second bearing support;an elastic member having a midportion and opposing ends, said elastic member being capable of bending from an original position to assume a more or less bowed position in response to changes in a load applied to the midportion of the elastic member intermediate said ends, said elastic member engaging said bearing structures at a distance spaced from each of said ends, said elastic member and said bearing structures cooperating to allow oscillation of said elastic member in response to a vibrating load in communication with said elastic member, said second bearing structure rotating in response to oscillation of said elastic member; anda mechanism for centering a load on said elastic member.
