Abstract:
One exemplary embodiment of a wheel rim comprises magnesium. The wheel rim has one or more flange(s) that are constructed and arranged to seat a bead portion of a tire. One exemplary embodiment of a wear resistant coating is located over the flange on at least a part of a section of the flange(s) that opposes the bead portion of the tire.
Abstract:
A wheel barrier assembly is disclosed for creating a physical barrier between a wheel hub, a wheel and a plurality of lugs securing the wheel to the wheel hub. The wheel barrier assembly may include a plate extending between the wheel hub and the wheel to insulate the wheel from the wheel hub. The wheel barrier assembly may also include a plurality of collets extending through the wheel and secured to the plate to insulate the wheel from the lugs.

Abstract:
Exemplary embodiments include a product and a method of galvanically isolating an outer wheel portion from a wheel hub. A center wheel portion may comprise a less galvanically active material than the outer wheel portion and may be attached to the outer wheel portion with an interlock.
Abstract:
An end ring assembly for a rotor, wherein the rotor is rotatable about a central longitudinal axis, includes a plurality of annular sheets stacked adjacent one another. Each of the plurality of annular sheets has a first surface and a second surface spaced opposite the first surface. The end ring assembly also includes a braze material sandwiched between and joining only a first portion of the first surface of each of the plurality of annular sheets, and a corresponding second portion of the second surface of a respective adjacent one of the plurality of annular sheets without joining an entirety of the first surface of each of the plurality of annular sheets and the second surface of the respective adjacent one of the plurality of annular sheets. A method of forming the end ring assembly is also disclosed.
Abstract:
A rotor core of an induction motor fabricating method includes a cylindrically shaped steel laminate stack having a plurality of longitudinal grooves distributed around the periphery of the steel laminate stack. A plurality of conductor bars are each located in one of the plurality of longitudinal grooves and each includes a first end projecting from a first end of the steel laminate stack. A shorting end ring includes a plurality of grooves aligned with and mated to the first ends of the conductor bars. The shorting end ring is affixed to the rotor core assembly by a lock ring assembled when at a thermally expanded condition to the rotor core when at a thermally contracted condition.
Abstract:
A method for fabricating a rotor assembly for an induction motor includes assembling a shorting end ring onto the rotor assembly which includes a steel laminate stack and a plurality of conductor bars. The shorting end ring includes a plurality of grooves aligned with corresponding portions of the conductor bars extending from a first end of the steel laminate stack. Assembling includes inserting the corresponding portions of the conductor bars into the grooves of the shorting end ring. The shorting end ring is affixed to the rotor assembly by applying a compressive force around a perimeter of the shorting end ring to deform the conductor bars.
Abstract:
A composite pressure vessel assembly method includes fitting an end portion of a tubular member into an annular slot formed in an end cap. Sealant may be in the annular slot. The end cap includes an annular groove in an exterior surface of the end cap body portion. A first material layer is formed on an exterior surface of the tubular member. The first material layer includes a first composite material including fibers oriented circumferentially to the tubular member. A second material layer is formed on the first material layer with a portion of the second material layer being disposed into the annular groove, and includes a second composite material including fibers oriented axially to the tubular member. A third material layer is formed adjacent the second material layer and in the annular groove, and includes a third composite material including fibers having an orientation circumferential to the tubular member.
Abstract:
A quick plastic forming (QPF) tool is provided in which a thermal gap is created that reduces or eliminates some of the conductive heat loss paths when the QPF tool is in an open position during part removal or sheet loading. By reducing conductive heat loss, a more precise temperature control for the QPF tool from manufacturing cycle to manufacturing cycle may be realized. The QPF tool may also have a thermal gap when the tool is placed in a semi-open position during idle times. The QPF tool may also include components for creating the thermal gap when the QPF tool is moved to the open position and control the lateral movement of the part forming section of the QPF tool as the part is moved between the open position and the closed position.
Abstract:
One embodiment includes a product including a metallic foam portion which may serve to reduce the weight of the product and/or vent the product and/or provide damping.
