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.
Claims31
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 engaging portion is immovably secured to the isolation body 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;
- and
- wherein radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.
The mounting system of claim I 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.
A mounting system for a vibrational element having a longitudinal axis and an outer surface comprising:
- an isolation member having an isolation surface;
- an engaging member extending radially from the isolating member at a position radially opposite the isolation surface wherein the engaging member is disposed so as to be normal to the longitudinal axis of the vibrational element;
- wherein the isolation member and the engaging member are non-resonant with the vibrational element;
- wherein the engaging member and isolation member substantially decouple the vibrations of the vibrational element member from the isolating surface while having a stiffness of greater than or equal to about 4.7×108 N/m.
A method for forming a mounting system on a rotary ultrasonic element having an annular outer surface comprising:
- forming a series of members on an isolating member;
- disposing the isolating member radially around the annular outer surface;
- interference fitting the members with the annular outer surface at nodal positions;
- and
- machining an outer surface of the isolating member to be concentric with the annular outer surface of the ultrasonic element.
