Abstract

A spindle for gas bearing of a rapidly rotating tool, in particular for aerostatic bearing arrangement of an open-end spinning rotor, including a spindle housing, a rotatable elongate shaft supported in the spindle housing in a radial direction of the shaft by a radial gas bearing element and an elongate extension rod. The rotor is coupled to the extension rod at a first end thereof. An extension rod bearing element is arranged at a region proximate the first end of the extension rod at which the rotor is attached. A first bearing clearance is defined between the radial bearing element and the shaft and a second bearing clearance is defined between the extension rod and the extension rod bearing element which is at least twice the first bearing clearance.

Dependent claims

Spindle for gas bearing of a rapidly rotating tool, comprising

a spindle housing,
a rotatable elongate shaft supported in said spindle housing by radial gas bearing means in a radial direction of said shaft, a first bearing clearance being defined between said spindle housing and said shaft,
an elongate extension rod having first and second ends, said extension rod being coupled at said first end to said shaft and unrestrained at said second end such that said extension rod is freely oscillatable from a coupling location of said first end of said extension rod to said shaft, said tool being coupled to said second end of said extension rod, and
an extension rod bearing arranged at a region proximate said second end of said extension rod, a second bearing clearance being defined between said extension rod and said extension rod bearing, said second bearing clearance being at least twice said first bearing clearance.
