A closing memberfor compressed air carrying polygonal tubes, which is inserted in a sealing manner into the polygonal tube at one end thereof. The closing memberincludes an elastic sealing element, and the closing member is constructed such that it biases in its inserted state the sealing elementin such a manner that it seals and secures the closing memberrelative to the polygonal tube. Closing members of this type are used to seal mounting tubes in yarn spinning machines with pneumatically loaded top roller support and weighting arms.

A roller for a belt stretching mechanism of a spinning machine has edge regions, a central zone which is depressed relative to the edge regions, and a radially movable sleeve located in a region of the central zone.

Roller for belt stretching mechanism

An open end spinning machine has a spinning rotor, an electric motor with an axial component of a main field having a rotor and a stator, a bearing housing for the spinning rotor, the rotor of the electric motor being arranged on the spinning rotor while the stator of the electric motor being arranged in the bearing housing, and a short shaft arranged so that the spinning rotor is supported on the short shaft near its center of gravity at least in a radial direction limitedly elastically in the bearing housing and magnetically pre-tensioned in an axial direction.

Drive and bearing for a shaft-less open-end spinning rotor

An open-end spinning machine has spinning stations and a magnetic and gas bearing with a stator at each of the spinning stations. A shaftless spinning rotor being electrically drivable with a single motor includes a series of spinning cups with different properties at each of the spinning stations for receiving fibers to be spun, and an electric rotor at each of the spinning stations forming an axial field motor with the magnetic and gas bearing and the stator. The spinning cups and the electric rotor have axially opposing end surfaces, and the end surfaces of the electric rotor and of one of the spinning cups at a time are coupled together to form a functionally appropriately releasable connection as a structural unit at each of the spinning stations.

A ball bearing has inner and outer raceways, and a row of balls mounted to roll between said raceways. The outer raceway is defined by an outer ring axially held in position by flanges of an outer sleeve. An axially extending space is provided between the outer ring and one of the flanges of the outer sleeve, for receiving a bearing element determined by the use in which the bearing will be placed. Examples of the bearing function-defining element are an annular seal, a corrugated annular spring, and the combination of a corrugated annular spring and a rigid washer.

Ball bearing

A bearing in which a cylindrical pin extends axially into a bearing shell, and is separated therefrom by rolling elements. A first annular seal includes an annular support body having a U-shaped cross-section and fitted into a recess in the open end of the bore of the shell, and a flexible first seal affixed to the support body and slidingly engaging the cylindrical surface. A second annular seat has a lip engaging an inclined surface at the open end of the shell, and extends to slidingly engage the cylindrical surface. An annular collar of the second seal extends into the open end of the support body, to engage an annular surface therein. The collar is radially slit.
