ABSTRACT:
A bearing and driving assembly is disclosed for an open end spinning rotor at a spinning unit of the type having a rotor mounted on a rotor shaft, a twin disk bearing arrangement for rotatably supporting the rotor shaft and a tangential belt drivingly engaging the rotor shaft of the radial side thereof opposite the twin dusk arrangement. To minimize failures of such a system caused by resonant system vibrations and to facilitate high spinning speeds with minimal manufacturing expenses, the assembly is designed so that the system critical velocity where excessive resonant vibrations may occur is substantially lower than spinning operational speeds.
