Abstract: A wing foil bearing may include one or more wing or tab foil layers. A tab foil layer may comprise a thin material with a two-dimensional array of tab shapes. A tab shape may be defined by a boundary of material separated from the thin material and having an integral edge and a free edge. Tab shapes may include one or more free-state bends relative to the thin material, forming a two-dimensional array of cantilever wings or tabs. Tab arrays may be one or more of various types or two-dimensional arrays, and a tab foil layer may include additional tab arrays and tabs. One or more tab foil layers may be engaged with a mounting surface layer and a counter-surface layer to form a wing foil bearing. Tab foil layers may be stacked and or nested, including partial nesting and complete nesting.

Abstract: A transmission in particular for wind power generators, with an epicyclic planetary gear arrangement having a sun gear, a ring gear, multiple planet gears and a planet carrier. The planet gears have planet gear teeth in mesh with sun gear teeth and ring gear teeth. Each planet gear is rotatably mounted via a radial slide bearing on a planet pin that is non-rotatably connected to the planet carrier. Each slide bearing includes a bearing hub positioned between the planet pin and the planet gear, which is non-rotatably connected to the planet pin. Between the bearing hub and the planet pin an annular support is formed, which seen in the axial direction has a smaller dimension than the bearing hub and/or a smaller dimension than the planet gear teeth of the planet gear.

Abstract: A worm drive includes a rotatably mounted worm shaft, and a device for compensating an unwanted axial backlash of the worm shaft. The device for compensating the unwanted axial backlash of the worm shaft includes two pressure bodies between which the worm shaft is clamped in the axial direction by a diaphragm spring device. The diaphragm spring is assigned to one of the pressure bodies.

Abstract: A slide bearing which can be manufactured at low cost is provided. The slide bearing (1) is provided with a cylindrical bearing main body (2) into which a shaft member is inserted, and an elastic ring (3) for urging the bearing main body (2) diametrically inward, the elastic ring (3) being mounted to the bearing main body (2). The bearing main body (2) has a sliding surface (21) which slides against the outer peripheral surface of the inserted shaft member, a plurality of first slits (25) running along the direction of an axis O from one end surface (23) toward another end surface (24), a plurality of second slits (26) running along the direction of the axis O from the other end surface (24) toward the one end surface (23), a plurality of first elastic ring interlocking parts (27) protruding diametrically outward at one end part (220) of the outer peripheral surface (22), and a plurality of second elastic ring interlocking parts (28) protruding diametrically outward at another end part (221) of the outer peripheral surface (22). The first elastic ring interlocking parts (27) and the second elastic ring interlocking parts (28) are positioned so as not to overlap each other seen in an imaginary plane P perpendicular to the axis O.
