ROTORWELLE EINES OFFENEND-SPINNROTORS

摘要

A rotor shaft of an open-end spinning rotor is provided with a peg-like shaft end having a reduced diameter. The shaft end has a front-end supporting surface which can be arranged to a step bearing, said supporting surface being provided with a wear-resistant insert. The reduced diameter of the peg-like shaft end is at least 0.68 times the diameter of the rotor shaft. In addition, the reduced diameter of the shaft end measures at least 0.82 times the length of the peg-like shaft end.
