Abstract: A gearcase seal assembly includes an inboard seal body and an outboard seal body both extending about and along a center axis between respective interior and exterior portions. The inboard and outboard seal bodies include respective inboard and outboard pockets configured to receive first and second surfaces of a gearcase of an axle assembly, respectively. The interior portions of the inboard and outboard seal bodies include respective gutters configured to direct fluid away from the first and second surfaces of the gearcase, respectively. The exterior portion of the inboard seal body includes plural fingers disposed outside of the inboard pocket and extending in one or more directions away from the inboard pocket. The exterior portion of the outboard seal body includes plural other fingers disposed outside of the outboard pocket and extending in one or more directions away from the outboard pocket.

Abstract: The invention relates to a method for the production of a catalyst system comprising a catalytically active component, in particular a supported catalyst, and to a catalyst system as such. The present invention also relates to uses of the catalyst system according to the invention and further to protective materials as well as filters and filter materials which are produced using the catalyst system according to the invention or which comprise such a catalyst system.

Abstract: A system is provided that may include a generator or alternator. A ceramic bearing assembly is within the alternator or generator. The ceramic bearing assembly may include one or more ceramic rolling elements formed of a ceramic material not including metal and disposed between a metallic inner race and an outer race of the ceramic bearing assembly.

Abstract: A seal structure can include a protruding portion of an outer surface of a body. An inner surface of the protruding portion may define at least a portion of a channel. The protruding portion may be configured to engage and at least partially deform into the channel in response to a load generated by pressing an outer surface of the protruding portion against a contact surface of a contact member to provide a seal between the body and the contact member. The seal structure may be integrally formed within the body as a monolithic object. The body may face towards the contact surface of the contact member during operation of the seal structure. A method may include forming a monolithic body with an integral seal structure by additively fusing material so that the body has an outer surface facing towards a contact surface of a contact member.

Abstract: An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position.

Abstract: A torque transmission and sealing assembly includes a ring gear having a first axial end, a second axial end opposite the first axial end, an inner surface including a plurality of teeth and an axial-facing surface at the first axial end, a barrel portion joined to the second axial end of the ring gear, and a plurality of annular, axial extending fingers integrally formed with the ring gear and extending from the axial-facing surface.

Abstract: This sensor, comprises: a first surface acoustic wave device, comprising a first piezoelectric substrate, formed from a (YXw/t)/?/?/? cut of a Langasite crystal, where ? is equal to 0±5° is equal to 55±20° and ? is equal to 32.5±7.5° and a first resonator having a first transducer laying on a first propagation surface and having two sets of interdigitated first electrodes formed from an electrically conductive material having a high melting temperature; and a second surface acoustic wave device, comprising a second piezoelectric substrate, formed from a (YXw/t)/?/?/? cut of a Langasite crystal, where ? is equal to 0±5°, ? is equal to 5±20° and ? is equal to 0±7.

Abstract: A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox.
