ABSTRACT:
A spindle is provided which is intended especially for use in the mounting arrangement of a spinning rotor within the spinning housing of a textile spinning machine. The spindle comprises an outer sleeve, two rows of balls disposed in cages, and a shaft whose external end portion is adapted to be driven by a drive arrangement for inducing rotary motion. The internal end portion of the shaft is disposed within the outer sleeve and forms a dynamically elastic portion of the shaft having a smaller diameter than that of the main spindle shaft. The spinning rotor is pressed on the dynamically elastic portion of the shaft. Between the rotor space, behind the spinning rotor and a compensation space, a rotary, or non-rotary, gasket is provided which includes a labyrinth knife.
