Abstract
The invention is a mounting system for a vibrational element. The vibrational element has a longitudinal axis, an outer surface and an axial displacement node. The mounting system includes an isolation member which has an isolation surface, an isolating body, and an engaging portion. The engaging portion is immovably secured to the isolation member and extends radially inward from the isolation body at a point radially opposite the isolation surface. The engaging portion is disposed so as to engage the outer surface of the vibrational element. Radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.
Claims6
A mounting system for a vibrational element having a longitudinal axis, an outer surface and an axial displacement vibration node on the outer surface comprising:
- an isolation member having an isolation surface, an isolation body and an engaging portion wherein the isolation member further comprises:
- a first ring formed of a first material;
- and
- a second ring formed of a second material wherein the first ring is integrally formed with the engaging portion;
- wherein the engaging portion is immovably secured to the isolation body at a nodal point and extends radially inward from the isolation body at a point radially opposite the isolation surface so as to engage the outer surface of the vibrational element;
- wherein radial displacements of the vibrational element are substantially decoupled from the isolation surface through the engaging portion;
- and
- wherein the vibrational element is an ultrasonic horn.
A mounting system for a vibrational element having a longitudinal axis and an outer surface comprising:
- an isolation member having an isolation surface;
- a plurality of engaging members extending radially from an isolation member at a position radially opposite the isolation surface wherein the engaging members are disposed so as to be normal to the longitudinal axis of the vibrational element when the engaging members are removably secured to the vibrational element;
- wherein the isolation member and the engaging members are non-resonant with the vibrational element;
- wherein the engaging members and isolation member substantially decouple the vibrations of the vibrational element from the isolating surface while having a stiffness of greater than or equal to about 4.7×108 N/m;
- wherein the vibrational element is an ultrasonic horn;
- and
- wherein the isolation member further comprises
- a first ring formed of a first material;
- and
- a second ring formed of a second material, wherein the first ring is integrally formed with the engaging members.
