  • Publication number: 20140334754
    Abstract: A landing bearing for use in a magnetic bearing assembly is provided. The landing bearing includes a first landing surface configured to be mounted on a shaft and a bushing having a second landing surface configured to be mounted in a housing or in a stator coaxially with the landing sleeve. The second landing surface is arranged so as to face the first landing surface. It is proposed that at least one of the first landing surface and the second landing surface is provided with at least one recess for receiving lubricant.

  • Publication number: 20130152716
    Abstract: The roller screw mechanism is provided with a screw including an external thread, with a nut arranged about and coaxial with said screw, the nut including an internal thread, and with a plurality of rollers inserted between the screw and the nut and each including an external thread engaging the external and internal threads of said screw and of said nut. The screw is axially moveable in relation to the rollers. The flanks of the thread of the screw have a concave profile in cross section.

  • Publication number: 20130074622
    Abstract: The roller screw mechanism is provided with a screw comprising an external thread, with a nut arranged around and coaxial with the said screw, the nut comprising an internal thread, and with a plurality of rollers interposed between the screw and the nut and comprising flanks interacting with the said threads. The value of the opening angle ? of the flanks of the external thread of the screw is greater than the value of the opening angle of the flanks of the rollers.

  • Patent number: 7148610
    Abstract: A surface acoustic wave device includes a transducer electrode formed on a substrate. In one aspect, the electrode has a plurality of layers. At least one of the layers is metal and another of the layers is a material for providing a hardening effect to the metal layer by reinforcement with Al2O3 precipitates. In another aspect, the electrode is electrically connected to a metal component that permits electrical connection of the surface acoustic wave device to an electrical device external to the surface acoustic wave device. The electrode has a metal portion of a first metallization. The component is of a second, different metallization. In other aspects, the surface acoustic wave device is made via a method to have such structural aspects.
