摘要： A high-speed ball bearing includes an outer ring, an inner ring, a plurality of balls, and a ball retainer. The ball retainer includes a plurality of pocket holes for arranging a plurality of balls, an inner circumferential surface of each of the pocket holes have a spherical surface is coaxial to the ball. A gap between an outer circumferential surface of the ball retainer and an inner circumferential surface of the ring is defined as a first gap, and a gap between the pocket hole and the corresponding ball is defined as a second gap. The first gap and the second gap have the following relationship: W2=(W1−r′)×A.

摘要： An apparatus and method for unloading a rotor bearing is described. The apparatus includes an electromagnet for levitating the rotor. In one embodiment, a sensor of the magnetic field near the electromagnet is used to control the current to levitate the rotor. In another embodiment, a method is provided that includes rotating the rotor, increasing the current to levitate the rotor and decrease the gap between electromagnet and rotor, and then reducing the current to levitate the rotor with a minimal amount of electric power to the electromagnet.

摘要： The invention relates to a motor vehicle clutch release bearing device including a rolling bearing that forms a member for transmitting an axial force, having a rotating ring and a non-rotating ring, between which a rolling chamber for rolling elements is defined. The rotating ring provides a first radial portion intended to come into contact with an actuating member when a sufficient axial force is applied to the non-rotating ring by a member that is able to move in translation, and a second radial portion that is intended to bear against a spring, which exerts an axial force in the opposite direction to the axial force exerted by the member that is able to move in translation, dedicated to preloading the rolling bearing in an opposite direction to the actuating member.

摘要： A vehicle seat includes a seat base and a seat back rotationally connected at a pivot. The seat base is rotatable about the pivot between a plurality of rotational positions relative to the seat base. A recliner disk is positioned at the pivot. The recliner disk includes a guide plate coupled to the seat base and a tooth plate coupled to the seat back. A plurality of bearings is positioned between the guide and tooth plates. The plurality of bearings and the guide and tooth plates are free of an internal braking mechanism. The engagement of the guide and tooth plates with the bearings provide for substantially free rotational movement between the plurality of rotational positions. The bearings also fix the relative axial position of the guide plate relative to the tooth plate.

摘要： A rolling bearing device includes a rolling bearing; and a spacer provided adjacent to one side of the rolling bearing in an axial direction and having a grease reservoir and a flow path, the grease reservoir being in a form of a groove, extending along a circumferential direction, and having grease reserved in the grease reservoir, and the flow path providing communication between the grease reservoir and an inner part of the rolling bearing. The spacer includes an annular wall surface that defines an inner periphery of the grease reservoir. An end of the annular wall surface on a side of the rolling bearing in the axial direction of the grease reservoir is continuous with an opposed end face of the spacer that is opposed to the rolling bearing. An entire area of the annular wall surface is constituted by a flat surface.

摘要： A rolling bearing apparatus includes: a bearing including an inner ring, an outer ring, a plurality of balls, and a cage; and an oil supply unit provided axially adjacent to the bearing. The oil supply unit includes a tank in which to accumulate lubricant, and a pump that receives the lubricant in the tank and supplies the lubricant to the bearing. The tank is provided with a holding material for the lubricant, the holding material having minute pores. The holding material includes a first holding portion provided in a region on an outlet-side of the tank, and a second holding portion provided in a part other than the region and having a porosity higher than that of the first holding portion.

摘要： An antifriction bearing cage is disclosed including cage pockets that are used for guiding rolling elements, in particular balls, and are formed by two lateral rings having a common axis of symmetry (R) and by webs interconnecting the lateral rings. The lateral rings are designed as single pieces along with the webs and contain a fabric. The fabric is composed of at least two types of different fibers which impart highly anisotropic properties to the fabric.
