  • Unitized seal with integral spacer
    Patent number: 7845740
    Abstract: A unitized seal assembly is provided for installation between linkages of a chain drive designed for tracked vehicles. The seal assembly facilitates field preventative maintenance on the drive chain by utilizing an integral spacer that holds the critical sealing surfaces together at all times, and has a seal head that can be easily removed from the outer link bore of a chain link. Removal of the seal head from the outer link bore causes as-installed clearance passageways between the seal head and seat portions and the spacer to forcefully close and prevent abrasive particles from getting inside the seal and reaching the interior interface junction of the dynamic sealing surfaces during seal maintenance. The seal assembly also includes additional sealing features that provide improved performance.

  • Two-Piece Valve Stem Seal
    Publication number: 20100295252
    Abstract: A valve stem seal utilizes a multi-piece construction to reduce the required manufactured tolerances and/or improve the stress handling capabilities. The valve stem seal can include a first member or can which can be assembled to a second member or spring seat. The can and/or spring seat can have a plurality of axially extending resilient fingers that are biased such that when assembled the fingers are bent against the bias due to the engagement between the can and the spring seat. The fingers on the spring seat allow the spring seat to bend or move relative to the can to accommodate the loading of a valve spring on the spring seat. The use of resilient fingers on the can and/or the spring seat reduces the manufacturing tolerances required for the valve stem seal.

  • Arrangement for connecting two shaft ends with a bearing
    Patent number: 7837565
    Abstract: An arrangement, comprising two shaft ends (1, 2), which are mutually connected by a coupling element (3) so as to transmit torque, the coupling element (3) being associated with a bearing (4), which receives at least one shaft end (1), the bearing (4) comprising a support body (5) for the shaft end (1) and an outside body (6) surrounding the support body, and an elastic deformable layer (7) being disposed between the support body (5) and the outside body (6), with the aim of creating an arrangement that guarantees the lowest possible cardan rigidity while achieving maximum radial rigidity, is characterized in that the elastic layer has at least in part a spherical configuration. A bearing also has at least in part a spherically configured layer.

  • Dryer sheets including bicomponent fibers
    Patent number: 7838449
    Abstract: A dryer sheet substrate is provided having improved loft and reduced fuzz wherein the substrate comprises relatively low denier bicomponent fibers. The bicomponent fibers may comprise two or more polymers having different melting temperatures, with the relatively lower melting temperature polymer making up at least a portion of the outer surface of the fiber. Upon heating to a sufficient temperature, the lower melting temperature fibers may soften and melt, providing bonding at crossover points of the fibers in the laid web. The web indicates advantageous characteristics with respect to thickness (loft), fuzz factor and ability to absorb a fabric treating composition.

  • Dynamic Seal
    Publication number: 20100264604
    Abstract: A dynamic shaft seal assembly is provided including a dynamic seal for engaging a rotary shaft. The dynamic seal includes a base portion that is mounted within a casing and has an axially extending barrel portion extending from a radially inner end of the base portion. The axially extending barrel portion terminates in a radially extending leg portion which extends inwardly from an end of the axially extending portion. A generally conically shaped seal portion extends from an end of the radially extending portion and the seal portion includes a radially inner face engaging the shaft and a radially outer face having a stiffening bead integrally formed thereon. The stiffening bead reduces the seal's propensity for “bell mouthing” while the axially extending barrel portion provides improved shaft followability for the dynamic seal.
