Abstract
A bearing and driving assembly is disclosed for an open and spinning rotor unit of 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. A tension roller is loaded against the tangential belt. To minimize failures of such a system caused by a resonant system vibrations and to facilitate high spinning speeds with minimal manufacturing expenses, the supporting disk pairs are axially spaced a distance slightly larger than the axial width of the tension roller. Brake members are disposed below the tangential belt so as to be applied with substantially horizontal movement radially against the rotor shaft.
