Abstract: A roller bearing provided with flanges and having an inner ring, an outer ring and roller elements therebetween, sealed to prevent penetration of foreign matter, and constructed so that at least one of the rings is integral with two flanges extending on either side of the ring.

Abstract: A sealing ring for sealing between a stationary first member and a second member coaxially rotatable in relation to said first member and having a rotationally symmetric surface zone. The sealing ring is adapted for stationary attachment relative to said first member and elastically deformable at its portion located closest to said second member. The sealing ring further includes two annular surface portions provided in spaced relationship to each other along said portion, said surface portions during absence of external actuation sealingly abutting the rotationally symmetric surface zone on said second member and having between themselves an intermediate annular groove, into which open a plurality of channels.

Abstract: A hydrostatic bearing having a cylindrical sleeve in which a shaft is located. The inner surface of the sleeve is formed with a plurality of bearing compartments about its periphery separated by axial webs. Each web is provided with a recess forming a chamber running parallel to the axis of the sleeve and having a radial hole communicating therethrough. Each hole is connected in common to a source of bearing media under pressure.

Abstract: An adjustable ball groove slide having a slide movable axially along a beam, with balls secured in recirculation paths between the beam and slide, and pressure members carried by the slide for partially defining said paths, with adjustment means for varying selectively the force on said pressure members and the play in the assembly of the beam, balls and slide.

Abstract: Wheel bearing application, including same for a wholly unloaded, rigid rear shaft, comprising drive means arranged in a sleeve portion for transferring torsional movement from a drive shaft and a bearing consisting of a moment-carrying, play-adjusted, rigid inner-ring-rotated roller bearing. The inner ring comprises two directly adjacent separate rings that are fitted on the sleeve portion and an outer ring of one piece, with rolling bodies arranged between the inner and outer rings.

Abstract: A fluid bearing system for journalling a shaft against radial and/or axial loads. The described bearing consists of a housing having at least one fluid compression chamber. The housing surrounds the shaft and is provided with at least one portion which is stationarily fixed with respect to the shaft. Inlet means are provided through the stationary portion for the introduction of air or liquid. A ring securely fixed to the shaft for rotation therewith extends in opposition to the stationary portion. The ring forms with a surface of the stationary portion a throttling gap between the inlet and the compression chamber by which the restriction of fluid flow is accomplished.

Abstract: An aerostatic bearing for the shaft of a spinning turbine of an open end spinning unit. The shaft is located in a cylindrically hollow housing to which gas under pressure is supplied to form a radial aerostatic bearing about the shaft. A permeable supporting sleeve is preferably interposed between the housing and the shaft. The shaft is provided with a radial duct and an axial bore opening only toward the rear end of the shaft. A supporting surface is fixed opposite the rear end of the shaft and is spaced therefrom so that the exhausting gaseous media impinges thereon and forms an axial bearing. Preferably, means are provided for resiliently biasing the shaft toward the supporting surface against the action of the axial aerostatic bearing. Such means are preferably magnetic.

Abstract: A bearing is provided with an inner and an outer ring, at least the innerring forming an integral part of a fixing or supporting flange, and rolling elements, arranged between the rings in a bearing-cage. Sealing elements prevent the penetration of dust, dirt and the like, while on the other hand retain the lubricant between the rings. The sealing element further includes a relatively rigid fixing part, the size thereof in radial direction being determined by the maximum eccentric or radial displacement of the rings with regard to one another during the assembly.

Abstract: A fluid bearing system for journalling a rotatable shaft in which an annular housing is fixed about the shaft and is provided with an inlet for the supply of fluid under pressure. At least one bearing compression chamber is formed in the housing and/or the shaft and is distributed about the periphery of the shaft. The housing and the shaft form an integrated throttle control means in which a restrictor opening and a discharge opening is formed between the housing and the shaft for the flow through of fluid from the inlet. The openings are simultaneously varied relative to each other in an opposing manner as a function of the size and distribution of the load placed on the shaft.

Abstract: A pump unit for liquid-cooled internal combustion engines preferably for vehicle engines and of the type including a pump unit housing, an impeller, a drive member operatively connected to the impeller to rotate the same and forming therewith a rotatable assembly, bearing means supporting the drive member for rotation relative to the housing and a seal adapted to seal an annular space between the rotatable assembly and housing characterized in that the axial length of the pump unit as measured from the impeller to the oppositely located end of the drive member and the pitch diameter of the bearing are of about the same order of magnitude.

Abstract: System for journalling a high speed rotary shaft in which a spherical fluid dynamic cap bearing is adapted to receive an end of the shaft. A magnet arrayed in the vicinity of the cap exerting a force axially on the shaft. The shaft is provided with magnetic material cooperation with the magnet, so that that the shaft is drawn and/or pushed into the bearing.

Abstract: A ball bushing device adapted to be mounted on a shaft, comprising a sleeve element containing a bore defined by an interior wall surface, plural balls within the sleeve, and a raceway structure between the balls and the sleeve element, the raceway structure having curved elastic plate members and having a generally concavo-convex surface facing toward the shaft and the concave surface facing toward the sleeve element.

Abstract: A method of manufacturing rotating electric machines comprising a stator and a rotor consisting of the steps of forming the stator in at least two sections by permanently moulding in a plastic mass at least the means providing the magnetic flux, positioning the stator sections to circumscribe the rotor and thereafter securing the stator sections in a fixed position relative to one another.
