摘要： A rotor shaft of an open-end spinning rotor is provided with a peg-like shaft end having a reduced diameter. The shaft end has a front-end supporting surface which can be arranged to a step bearing, said supporting surface being provided with a wear-resistant insert. The reduced diameter of the peg-like shaft end is at least 0.68 times the diameter of the rotor shaft. In addition, the reduced diameter of the shaft end measures at least 0.82 times the length of the peg-like shaft end.

摘要： A bearing and driving assembly is disclosed for an open and spinning rotor unit of a spinning unit of the type having a rotor mounted on a rotor shaft, a twin disk bearing arrangement for rotatably supporting the rotor shaft and a tangential belt drivingly engaging the rotor shaft. A tension roller is loaded against the tangential belt. To minimize failures of such a system caused by a resonant system vibrations and to facilitate high spinning speeds with minimal manufacturing expenses, the supporting disk pairs are axially spaced a distance slightly larger than the axial width of the tension roller. Brake members are disposed below the tangential belt so as to be applied with substantially horizontal movement radially against the rotor shaft.

摘要： In the case of an open-end spinning arrangement, a spinning rotor is arranged in a rotor housing, to which a vacuum of at least 500 mm water column is applied. A fibre feed channel, beginning at an opening roller with an entry opening, is directed with an outlet opening at a sliding wall of the spinning rotor. The fibre feed channel bends slightly in the direction towards a fibre collecting groove of the spinning rotor. The cross sectional area of the outlet opening of the fibre feed channel measures at least 19 mm.sup.2 and amounts to at least 30% of the cross sectional area of the entry opening. As a result of the bend in the fibre feed channel, the fibres are collected together in a fibre bundle on a longitudinal side of the fibre feed channel. The fibre bundle occupies only a part area of the outlet opening when leaving the fibre feed channel and is fed with high precision onto the sliding wall. The outlet opening can thus have larger dimensions without this leading to inaccurate feeding of the fibres. The outlet opening possesses dimensions that permit a large volume of air to flow at high speed from the opening roller through the fibre feed channel. Fly accumulation in the area of the opening roller is thus avoided.
摘要翻译：在开放式纺纱装置的情况下，在转子壳体内设置有旋转转子，在该壳体内施加至少500mm的水柱的真空。从具有进入开口的打开辊开始的纤维进料通道与纺丝转子的滑动壁处的出口开口导向。纤维进料通道沿着纺丝转子的纤维收集槽的方向稍微弯曲。纤维进料通道的出口开口的横截面积至少为19mm 2，并且相当于入口的横截面面积的至少30％。由于纤维供给通道的弯曲，纤维在纤维供给通道的纵向侧以纤维束收集在一起。当离开纤维进料通道时，纤维束仅占出口开口的一部分区域，并且高精度地供给到滑动壁上。因此，出口开口可以具有更大的尺寸而不导致纤维的不准确的供给。出口开口具有允许大量空气以高速从打开辊通过纤维进料通道流动的尺寸。因此避免了在打开辊的区域中的飞累积。

摘要： An opening roller unit for open-end spinning installations as a shaft supported in a bearing box and an opening roller arranged on an end of the shaft which projects from the bearing box. The opening roller extends over the bearing box in a manner forming a cavity that is sealed toward the outside with an annular sealing gap and comprises the base member and the ring detachably secured thereto which has a fitting provided on the outer periphery thereof. The detachable ring is mounted upon the base member in a manner blocking the external axis to the cavity. In accordance with one preferred embodiment, the ring of the opening roller extends over the bearing box and the cavity is defined by the ring and bearing box, while the scaling gap is provided between the ring and the bearing box in conjunction with an annular insert attached to the bearing box. In an alternative embodiment, the base member extends over the bearing box and defines the cavity in conjunction therewith, while the detachable ring blocks axis to the cavity by covering radial openings formed in the base. In accordance with an advantageous feature, the frictional connection between the base member and the ring secured thereto is provided by an annular spring band received within an annular groove provided on an outer surface of the base member.

摘要： An opening roller for an open-end spinning arrangement is provided with a combing ring, which is slidably mounted onto a base body and is supported between two clamping surfaces. In order to fix the combing ring radially to a cylindrical guiding surface of the base body, the combing ring is provided with a centering surface on its inner circumferential surface. The combing ring has stopping surfaces on its end sides, which are arranged to engage the clamping surfaces. The centering surface is limited to an end area of the inner circumferential surface. The part of the inner circumferential surface of the combing ring which is located outside of this end area is free from counter-surfaces of the base body. As a result of this arrangement, the seat-engaging surfaces are on the one hand very short, while on the other hand various embodiments of combing rings can be used.
