摘要： A step bearing is provided to axially support a shaft of an open-end spinning rotor, having a step bearing housing with a freely rotatable supporting ball, against which the end of the shaft is supported. The step bearing housing has a take-up space in the form of a lubricating grease reservoir in which the supporting ball is located. A lubricant distributor is arranged at the take-up space and is movable relative thereto.

摘要： In the case of an opening device for an open-end spinning machine, the rotating opening roller is arranged in a housing with a prevailing vacuum and has one front side which is exposed to the free atmosphere. In the area of this front side the opening roller is sealed off against the housing by means of a labyrinth seal. The labyrinth seal starts in the area of a peripheral combing structure of the opening roller with a first sealing gap and ends with a second sealing gap in the free atmosphere. The sealing gaps are formed by cylindrical collar surfaces of the opening roller and corresponding hollow cylindrical countersurfaces of the housing. In addition, the collar surfaces are provided with fly repulsing notches, whose direction of effect is such that the fly is repulsed at the first sealing gap towards the combing structure and at the second sealing gap, repulsed towards the free atmosphere. The front side of the open roller exposed to the free atmosphere is not covered by a lid.
摘要翻译：在开口纺纱机的打开装置的情况下，旋转打开辊布置在具有主要真空的壳体中，并且具有暴露于自由气氛的一个前侧。在该正面的区域中，打开辊通过迷宫式密封件与壳体密封。迷宫式密封件在具有第一密封间隙的打开辊的外围精梳结构的区域中开始，并且在自由气氛中以第二密封间隙结束。密封间隙由开口辊的圆柱形套圈表面和壳体的相应的中空圆柱形对面形成。此外，套环表面设置有飞行排斥凹口，其作用方向是使得飞沫在第一密封间隙处朝着梳理结构排斥，并且在第二密封间隙处朝向自由气氛排斥。暴露于自由气氛的开放辊的前侧不被盖子覆盖。

摘要： An opening roller for an open-end spinning device comprises a shaft supported in a bearing housing. A base body is arranged on the shaft, on which base body an exchangeable ring with combing structure is slidably arranged . The ring with combing structure is fixed at its end faces between a flange of the base body and a flange of a detachably applied tension disc. In order to brace the tension disc against the ring with combing structure by means of a spring element, a screw is axially screwed into the shaft, which screw is provided with working surfaces for a tool for pulling the opening roller out of a holding device of the bearing housing. The working surfaces are located at the end of a through bore hole of the screw on the side facing away from the head of the screw. The tension disc has an even outer front surface, which is partly formed by a covering cap, which comprises, in extension of the through bore hole, a small bore hole for inserting the tool.
摘要翻译：用于开放式旋转装置的打开辊包括支撑在轴承壳体中的轴。基体设置在轴上，基体具有可滑动地布置有梳理结构的可更换环。具有梳理结构的环在其基体的凸缘和可拆卸地施加的张力盘的凸缘之间的端面处固定。为了通过弹簧元件将紧固盘支撑在具有梳理结构的环上，螺钉被轴向地拧入轴中，该螺钉设置有用于将开启辊拉出保持装置的工具的工作表面轴承座。工作表面位于螺钉的通孔孔的远离螺钉头部的一侧的末端。张紧盘具有均匀的外前表面，其部分地由覆盖帽形成，其包括在通孔的延伸部中的用于插入工具的小孔。

摘要： A yarn withdrawal nozzle is provided for an open-end spinning arrangement, the essentially funnel-shaped contact surface of which consists of a material which, in a temperature range of approximately 50.degree. C. to approximately 100.degree. C., has a thermal conductivity of at least 80 W/mK (Watts per meter Kelvin) so that as a result damage to synthetic fibers caused by overheating is avoided also in the case of relatively high rotational rotor speeds.

摘要： An opening roller for an open-end spinning arrangement is disclosed which contains a basic body pressed onto a shaft. This basic body contains an exchangeable ring mounting which is held by means of its end faces between a flange of the basic body and a tension disk. It is provided that the tension disk fitted onto the shaft is loaded in the axial direction by means of a screw which is screwed axially into the shaft and which, by means of the head, rests against the front face of the shaft. A spring element, preferably a cup spring, is arranged between the head of the screw and the tension disk.
