Abstract
A spindle includes a shaft, at least one non-contact bearing in operable communication with the shaft, and a housing in operable communication with the at least one non-contact bearing. The shaft is rotatable relative to the housing, and at least one non-contact thrust bearing in operable communication with the shaft is configured to transfer oscillations to the shaft in directions parallel to an axis of the shaft.
Claims16
A spindle, comprising:
- a shaft;
- at least one non-contact bearing in operable communication with the shaft;
- a housing in operable communication with the at least one non-contact bearing such that the shaft is rotatable relative to the housing;
- and
- at least one non-contact thrust bearing in operable communication with the shaft configured to transfer oscillations to the shaft in directions parallel to an axis of the shaft.

A shaft supporting device, comprising:
- a housing;
- a shaft in operable communication with the housing;
- at least one non-contact bearing in operable communication with the housing and the shaft configured to provide radial support to the shaft;
- a bearing support in operable communication with the housing and the shaft via at least one non-contact bearing;
- and
- at least one non-contact thrust bearing in operable communication with the bearing support and the shaft configured to transfer oscillatory motion from the bearing support to the shaft.
3 more elements
A method of supporting a rotatable shaft, comprising:
- rotationally supporting a shaft with at least one non-contact bearing;
- axially positioning the shaft with at least one non-contact thrust bearing;
- and
- transferring axial oscillations to the shaft through the at least one non-contact thrust bearing.
