Abstract
In rotor spinning devices whose rotors are mounted in a support-disk bearing and in which a support disk (1) has openings (5, 9) serving for the contactless measurement of speed for an optical control of a spinning-start carriage, deposits of dirt, especially fine dust, can build up in said openings (5, 9). This impairs the detection of signals. The portion of the inner surface (19) of the openings (6, 9) of a support disk (1) which is located in the direction of the outer edge of the support disk (1) forms such an angle (α) with a line parallel to the axis of rotation (27) that the buildup of deposits of dirt is prevented.
Claims10
In a rotor spinning device having a sensor device with a light source which emits a light beam and with a receiving device for receiving the light beam, a support disk (1) comprising openings (5 to 12, 15, 25, 26) disposed in a measuring range of the light beam of the sensor device, each of the openings (5 to 12, 15, 25, 26) having an inner surface (19) at least a portion of which is located in the direction of an outer edge of the support disk (1) and forms an angel (α) with a line parallel to the axis of rotation (27) of the support disk (1) for preventing accumulation of debris during the operation of the rotor spinning device.
