The collars include a small diameter collar of which a press-fit portion has an outer diameter which is press-fitted into an inner diameter of the small diameter portion, and a large diameter collar of which a press-fit portion has an outer diameter which is press-fitted into an inner diameter of the large diameter portion.

Abstract: The flyer and spindle brake assembly for hand spinning wheels includes a cantilevered spindle and flyer assembly extending from a single maiden post. The spindle base is secured in an adjustable brake mechanism installed in the upper end of the maiden. The flyer has a closed distal end with a spindle bearing and yarn orifice. The flyer is urged toward its whorl or drive pulley by a coil spring on the spindle. The flyer is pulled axially outwardly away from the whorl to release the distal end of the spindle therefrom, the flyer then pivoting from the spindle axis for installation or removal of a bobbin or spool on the spindle. The brake mechanism provides extremely fine and accurate adjustment of braking force for the spindle and spool, while the flyer mechanism allows removal and installation of a spool on the spindle without the need for disassembly of components.

Abstract: A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.

Abstract: In the case of a spinning or twisting spindle, it is provided that the spindle shaft is radially fixedly disposed in the spindle bearing housing, and that centering devices and vibration damping devices are integrated into a holding arrangement for the spindle bearing housing.

Abstract: A bearing assembly for a spinning or twisting spindle shaft is provided which includes at least one support bearing device for supporting a shaft.

The lubricant feeding and discharging duct member includes an outlet discharging member for discharging lubricant out of a bearing housing.

Abstract: A mount for spinning spindles which discloses various embodiments of wedge type clamping devices for clamping a sleeve, which is disposed around the spindle housing, securely to a spindle bearing plate. The sleeve surrounds the spindle housing with vibration damping elements between them. The wedge clamping devices are driven by a threaded nut which is tightened up around the sleeve and this clamps the sleeve to the plate. A device for separating the drive belt from the drive whorl of the spindle is attachable on the sleeve and presses the belt off the drive whorl, freeing the spindle so that it may then be unclamped for removal from the spindle bearing plate.

Abstract: A device for supporting the spindles of textile machines, in which a spindle support cartridge is radially held by means of a double system of elastically-yielding thrust members, disposed inside an outer casing for the cartridge, and radially acting on the cartridge itself.

Abstract: A resilient element connects the housing of the spindle collar bearing with the spindle rail and contains a circumferential arrangement of resiliently flexible rods surrounding with play the housing of the spindle collar bearing in a substantially parallel relationship thereto. The resiliently flexible rods which are arranged at substantially uniform circumferential spacing from one another extend at both of their ends from an associated common retaining sleeve for the related rod ends. One such retaining sleeve is anchored at the spindle rail. The other retaining sleeve is fixedly anchored at the housing of the spindle collar bearing in a region or at a location spaced from a housing side at which the spindle exits from such housing. The resilient element forms a spatial parallelogram permitting only radial movement of the housing against the spring action of the resiliently flexible rods without inclined positioning of the housing.

Abstract: In order to be able to achieve, in yarn manufacture, the very high speeds required by the textile industry in open-end spinning devices, for the purpose of increasing production, and in order to achieve high operating reliability and a long life of the spinning devices, the rotor which rotates at high speeds and is subject to a variable imbalance and which is guided in gas-dynamic radial plain bearings is guided in a bearing carrier which is elastically pivotable in relation to the rigid bearing journal. At the same time, the bearing journal is connected, but so as to be elastically pivotable, to the bearing carrier via a bearing-body joint. A first gas-dynamic radial plain bearing, which is located in the region in the center of gravity of the rotor, is arranged on the bearing carrier, and a second gas-dynamic radial bearing is arranged at the opposite end of the bearing carrier.

Abstract: A spindle brake for a spinning or twisting machine has a pair of arms whose jaws are engageable with the whorl of a spinning or twisting spindle. One of these arms carries a belt-lifting roller adapted to lift the belt away from the whorl when the brake is actuated thereby preventing friction between the belt and the immobilized whorl.

Abstract: A row of spindles carried on a common rail have whorls in tangential contact with a driving belt urged toward the spindle axes by pressure rollers offset therefrom, the whorls being of a diameter on the order of half the roller diameter. Each whorl is journaled on an upper end of an upright, stationary shaft supported by the rail through two vertically separated elastic retainers.

Abstract: A new locking arrangement is disclosed for effectively locking bobbins in place on associated roving machine spindles. The locking arrangement includes a body that is drivingly connected to the spindle and has torque transmitting surfaces coacting with the bobbin. A deformable retainer is moveably coupled to the body. An over center cam is moveably coupled to the body and is coactable with the retainer in retainer compression and a retainer release position. When the cam is in the compression position, the retainer is deformed into a lock producing position securing the body and the bobbin in a torque transmitting relationship with forces which include an axial vector urging the members together. When the cam is in a release position, the bobbin can be removed from the spindle.

Abstract: A spinning or twisting spindle is formed of a one-piece metal spindle top having a spindle shank and a whirl formed of a die cast aluminum alloy, and preferably one containing more than 12 percent silicon in crystalline form. The spindle is formed according to preferred methods whereby the spindle top is die cast so as to produce a spindle that is overized relative to an intended final size, the cast spindle top is machined to its final size and a fixed connection is formed between the shaft and the spindle top. The connection, in one embodiment, is created by press fitting the shaft into an opening cast into an end of the spindle top, while in a second method, the connection is formed by die casting the spindle top about the shaft.

Abstract: A textile spindle mount is provided by the subject invention in which a layer of elastomeric material is disposed between and attaches to a flat washer along its bottom surface and a cupped washer along its top surface. The cupped washer includes end sections which extend downwardly and attach to the outer edge of the elastomer layer for limiting the bulging thereof under compression loads. The bulging of the elastomer layer is further controlled by removing a generally curved section of elastomeric material adjacent the outer edge of the elastomer layer. As a result, a high compression to shear springrate ratio is obtained with the spindle mount herein which is capable of good noise and vibration isolation and can accommodate high compression loads without bond failure.

Abstract: An adjustable support system mounts one member, such as a textile spindle, on a second member, such as a textile machine rail, so as to reduce the transmission of vibrations between the two members. The support system incorporates a flange to which is secured an elastomeric element for resiliently mounting the textile spindle relative to the flange. The flange is kept spaced apart from the machine rail by a member or members that at least contact the flange and at least contact the machine rail. The spacing between the flange and the machine rail can be adjusted through manipulation of adjusting screws or bolts in such a manner as to change the orientation of the flange and the textile spindle mounted on the flange relative to the machine rail. Like the spacing member, the adjusting elements contact both the flange and the machine rail.
