Shaft bearing for mounting a spinning rotor of a rotor spinning machine

Abstract

The invention relates to a shaft bearing for mounting a spinning rotor of a rotor spinning machine, with a double-row rolling bearing, which comprises two rolling-body rows that roll on their inner side without an inner ring, on two inner bearing races arranged at a distance from one another on a rotor shaft, and on their outer side on outer bearing races of two separate outer rings. According to the invention, the outer rings are mounted resiliently in a shaft bearing housing so as to provide a shaft bearing for mounting a spinning rotor of a rotor spinning machine with high reliability, even at rotational speeds of more than 110,000 revolutions per minute, which shaft bearing also allows trouble-free operation of a rotor spinning machine equipped with the shaft bearing.
