  • Patent number: 8353420
    Abstract: A horizontal hinged closure with a large diameter track ring attached directly to the rear of a female threaded head. The threaded female head is designed to removably attach to a male threaded structure. A bearing ring with cam followers that engage the track ring to allow the threaded head to be rotated relative to the male threaded structure to attach and remove the threaded head there from. The bearing ring is attached to a hinge arm that allows the removed threaded head to be moved away from the male threaded structure and then rotated about a vertical axis. Direct attachment of the large diameter track ring to the rear of the threaded head moves the center of gravity forward, resulting in the threaded head remaining essentially vertical when it is removed from the male threaded structure and thereby making it easier to reattach to the male threaded structure.

To oppose axial drift of the workpiece, each idler roller is rotatably journalled on a respective idler axle such that the axis of rotation of the idler roller is oriented obliquely relative to a pivot axis of the idler axle. The idler axles may be pivoted about their respective pivot axes to adjust the orientation of the idler roller axes relative to the workpiece to introduce an axially directed force component acting on the workpiece to counter axial drift. Pivoting of the idler axles may be automatically controlled based on a signal generated by a drift sensor arranged to detect axial drift of the workpiece.

    Abstract: To further reduce the manufacturing cost of a shell type needle roller bearing, and to ensure high quality of the shell type outer ring by subjecting the outer ring to a heat treatment that needs no adjustment of the atmosphere. The steel sheet to be formed into the shell type outer ring 1 by pressing is made of a medium to high carbon steel containing carbon by not less than 0.3 mass percent. With this arrangement, the material cost and thus the manufacturing cost are lower than when using a conventional low-carbon structural alloy steel sheet or a steel sheet for cold rolling and pressing. Also, it is possible to ensure high quality of the outer ring by subjecting the outer ring to simple heat treatment without the need for carburizing or carbonitriding, which needs adjustment of the atmosphere.

In order to be able to achieve an optimal self-adjustment with easy action of each supporting roller, each bedplate is supported by way of two articulated bearings disposed at a transverse spacing from one another on the foundation, of which the inner articulated bearing is constructed in the form of a ball-and-socket bearing, whilst the outer articulated bearing forms a movable bearing and is supported on the foundation so as to be slidably movable about the central point of the ball of the inner articulated bearing.

  • Patent number: 6337525
    Abstract: The present invention relates to a bearing for an open-end spinning rotor. The latter is driven at its rotor shaft by means of a tangential belt in a predetermined direction and is supported in a nip which is formed by at least two bearing disks capable of being driven by the rotor shaft. A bearing disk (at least one) leads in relation to the drive direction of the tangential belt rotating into the nip, and another bearing disk (at least one) trails in relation to the drive direction of the tangential belt rotating out of the nip. The axis of the bearing disk (at least one) rotating into the nip is at a specified distance from the plane which goes through the rotor shafts of the spinning rotors of several adjoining open-end spinning devices. This distance is being smaller than the distance between the axis of the bearing disk (at least one) rotating out of the nip and the rotor shaft plane.

    Abstract: An apparatus and method for polishing a workpiece including a polishing pad, and at least one polishing arm for holding a workpiece to be polished on the polishing pad. The polishing arm includes at least one plastic bearing. The plastic bearing prevents lock up of a vacuum chuck coupled to the polishing arm because it is impervious to slurry which often becomes lodged in conventional ball bearings.

  • Patent number: 6220761
    Abstract: For a bearing arrangement of an open-end spin rotor, which is rotatably set in the “V” between circumferential rims of support disks, one or more of the support disks (14), which bear the open-end spin rotor, has a circumferential cleaning groove (3). The cleaning groove (3) can be a self closing, endless groove, which runs over the contact surface of the support disk (14), wherein it generally does not run parallel to the edges of the support disk (14). Such a meandering groove formulation of the support disk circumference assures that no deposits of impurities can accumulate on the rotor shaft.

  • Patent number: 6212868
    Abstract: The spinning rotors of open-end spinning aggregates are supported on supporting discs. For the purposes of non-contact revolution counting, a front side of a supporting disc is provided with at least one permanent magnet. A signal receiver of a maintenance device selectively arrangeable at the spinning aggregates is arranged at the permanent magnet. The distance between the permanent magnet and the signal receiver is bridged by a ferromagnetic information transmitter, which is preferably arranged on a swivelling housing section of the spinning aggregate.
