Patent number: 4759226Abstract: A device for measuring the tensile force on a thread includes a housing having thread guides at the points of inlet and outlet of the thread. A spring plate is mounted on the housing intermediate the thread guides and has a dumbbell-shaped guide member at its end for engaging the thread. The spring plate is so mounted that the tension on the thread displaces the spring plate from its initial unflexed position. Adjacent the guide member on the movable spring plate is a permanent magnet which moves with the spring plate as it displaces. A sensor employing the Hall effect is fixed to the housing at a given distance from the magnet. Movements by the magnet are detected by the Hall sensor, which produces an output signal indicative of the displacement of the spring plate, which signal is processed to give an indication of the thread tension.Type: GrantFiled: February 25, 1986Date of Patent: July 26, 1988Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventor: Erwin Leurer

Patent number: 4756150Abstract: 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.Type: GrantFiled: June 8, 1987Date of Patent: July 12, 1988Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventors: Gunther Schmitt, Gunter Oppl, Armin Bohn

Patent number: 4726549Abstract: An electromagnetically actuatable pressure modulator for anti-locking brake systems utilizes a variable lever-type transmission interposed between a pressure relief piston of the modulator and the compression spring biased armature of an electromagnet whereby the non-linear force/air-gap relationship of the electromagnet is converted to a linear variation of the force applied to the pressure relief piston for moving same. When a predetermined maximum brake pressure is applied to the modulator, the latter automatically isolates the wheel cylinder from the master cylinder.Type: GrantFiled: August 21, 1986Date of Patent: February 23, 1988Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventors: Adam Dittner, Franz Fellner, Norbert Oberlack, Erich Graf, Joachim Sauer, Ulrich Sieme

Patent number: 4725081Abstract: A detachable plug assembly for making a connection between a pipe and an external unit such as a hose fitting or hydraulic unit, for example, in which the pipe can be automatically locked in a well-defined axial position in a bore of the external unit, and thus be assembled in a short time on an assembly line, particularly in the case of assembly by robots, without requiring special tools for either assembly or disassembly. The assembly comprises a bushing which is mountable in a fixed axial position on the pipe, the bushing having a conical shoulder at a forward end thereof for axially engaging the bore of the external unit and centering the pipe therein. The external unit has slots through which project the free ends of a locking element. The free ends extend into the bore of the external unit and engage a groove in the bushing for retaining the pipe in the bore of the external unit.Type: GrantFiled: September 8, 1986Date of Patent: February 16, 1988Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventor: Herman Bauer

Patent number: 4707152Abstract: A cage for a tapered roller bearing includes a small diameter ring, a large diameter ring and circumferentially spaced arms joining the rings and defining pockets for the tapered rollers. The inwardly facing opposite surfaces of the arms in a pocket including an axial region adjoining the large diameter ring, which is also radially outside of the mold parting line developed during the formation of the cage. Those surfaces of the arms in the region adjoining the large side ring of the cage are shaped to the roller within the packet. In each cylindrical sectional plane through the bearing, which also passes through each of the rollers and is parallel to the axis of the bearing, the distance apart of the surfaces of the arms is approximately the length of a chord of the largest diameter of the roller in that cylindrical sectional plane.Type: GrantFiled: January 20, 1987Date of Patent: November 17, 1987Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventor: Gerhard Neese

Patent number: 4665333Abstract: A separator for accurate positioning and easy replacement of magnets in an annular array around a spindle comprises an annularly shaped, elastic separator constructed of plastic materials. The plastic separator includes either cross machine struts that define open bottom recesses or it includes closed bottom recesses for receiving and accurately positioning and retaining the magnets circumferentially around its annular body. The separator applies an initial stress to the magnets to assure precise positioning. Radially directed projections on the body of the separator are shaped to fit into a groove defined in the interior of a motor housing, whereby the magnets carried by the separator are precisely located relative to the motor housing. The Separator-based magnet fixing means are particularly suitable for disk storage spindle applications.Type: GrantFiled: February 27, 1986Date of Patent: May 12, 1987Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventors: Edgar Heim, Horst Voll

Patent number: 4650195Abstract: A seal for an anti-friction bearing, which bearing includes an outer and inner ring and rolling elements riding between them. At the inner ring, the seal includes an axially outwardly extending leg or membrane, the radially inward side of which carries two axially spaced apart sealing ridges which are resiliently biased against the inner ring for effecting a seal. In the above axial membrane, there is an additional membrane of smaller cross section formed by a radial constriction of that axial membrane between the two sealing ridges, which makes the support of the axially outward sealing ridge more flexible. The distance between the sealing ridges is at least equal to the axial clearance in the completed installed bearing.Type: GrantFiled: April 18, 1986Date of Patent: March 17, 1987Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventors: Peter Dreschmann, Wilhelm Walter

Patent number: 4633661Abstract: In a friction false-twisting unit including three parallel spindles supported on a mount and each spindle carrying a stack of friction disks and the friction disks of the various spindles being interleaved, the thread to be threaded into the unit passing from an upper thread guide above the ends of the spindles, over a thread guide arm which holds the thread away from contact with the disks, and to a feeder system below the other end of the spindles. A support lever is movable between an operative position which holds the drive whorl for the spindles in contact with an operating belt and an inoperative position at which the spindle mount is moved to separate the drive whorl from the belt. The thread guide arm is on the support lever to be moved to the position holding the thread away from the disk when the support lever is moved to the inoperative position of the unit.Type: GrantFiled: May 24, 1985Date of Patent: January 6, 1987Assignee: FAG Kugelfischer Georg Schafer (KGaA)Inventors: Gunther Paul, Kirit Patel, deceased

Patent number: 4620101Abstract: The disclosure concerns a bar dosimeter used for measuring ionizing radiation. In a hollow housing, an axially deflectible contact pin is centrally supported in a deflectible membrane. The pin and the membrane are deflectible over center to a first deflected position wherein the pin engages another contact leading to an ionizing capacitor, and to a second deflected condition, where the pin is spaced away from the contact of the capacitor. Stops supported in the housing define the first and second deflected positions of the pin and the membrane. A spring acts through an intermediate piece to normally bias the pin and the membrane to the second deflected condition where the pin is out of engagement with the contact.Type: GrantFiled: December 5, 1984Date of Patent: October 28, 1986Assignee: Fag Kugelfischer Georg Schafer KGaAInventor: Werner Merkel
