Abstract
A godet roll for guiding at least one yarn on the circumference of a hollow-cylindrical godet roll casing. The godet roll casing is rotatably seated on a projecting support by a bearing arrangement which includes a radially acting magnetic bearing having a plurality of bearing pole windings distributed in the circumferential direction on the support. The bearing pole windings are arranged on the support at spacings from one another circumferentially about the support and also at spacings along the support in a plurality of adjacent bearing planes in order to make possible a low-vibration guidance of the godet roll casing.
Claims26
A godet roll for guiding at least one yarn, the godet roll comprising a projecting support, a hollow-cylindrical godet roll casing forming a circumferential yarn guiding surface, and a bearing arrangement rotatably seating the godet roll casing on the projecting support, the bearing arrangement comprising a radially acting magnetic bearing having a plurality of bearing pole windings spaced both about the support in the circumferential direction relative to the godet roll casing and along the support in a plurality of adjacent bearing planes, wherein only one of the bearing pole windings of the radially acting magnetic bearing is arranged in each of the bearing planes.
A godet roll for guiding at least one yarn, the godet roll comprising a projecting support, a hollow-cylindrical godet roll casing forming a circumferential yarn guiding surface, and a bearing arrangement rotatably seating the godet roll casing on the projecting support, the bearing arrangement comprising a radially acting magnetic bearing having a plurality of bearing pole windings spaced both about the support in the circumferential direction relative to the godet roll casing and along the support in a plurality of adjacent bearing planes, wherein a pair of the bearing pole windings disposed opposite each other is arranged in each of the bearing planes.
