Abstract
An ultrasonic resonator support structure including a holder supports an ultrasonic resonator at both sides such that the ultrasonic resonator is rotatable to the holder. The ultrasonic resonator includes an ultrasonic horn with a machining tool attached, and a first booster and a second booster coaxially fixed one by one to both ends in the axial directions of the ultrasonic horn. The holder has a rolling bearing mechanism that rotatably supports the first booster side of the ultrasonic resonator and a gas bearing mechanism that rotatably supports the second booster side of the ultrasonic resonator.
Claims18
An ultrasonic resonator support structure configured to support an ultrasonic resonator at both sides rotatably to a holder, the ultrasonic resonator including an ultrasonic horn with a machining tool attached and a first booster and a second booster coaxially connected one by one to both ends in axial directions of the ultrasonic horn, the holder provided in the ultrasonic resonator support structure comprising:
- a rolling bearing mechanism rotatably supporting a first booster side of the ultrasonic resonator;
- and
- a gas bearing mechanism rotatably supporting a second booster side of the ultrasonic resonator, wherein the rolling bearing mechanism supports a force applied in a thrust direction, and the gas bearing mechanism rotatably supports the second booster side of the ultrasonic resonator by a radial gas bearing part.
