Abstract: A ball bearing which includes a cage which defines recesses for receiving balls in a single row. The cage is in the form of a ring obtained by casting or machining and is intended to be interposed between an inner ring and an outer ring of the bearing. The cage includes recesses of a first group each having an opening for positioning a ball located on a first side of the cage, while recesses of a second group each have an opening for positioning a ball located on a second side of the cage, opposite the first side.
Abstract: This invention relates to a process for hard-coating a ball, consisting in:hollowing in the outer surface of the ball a depression whose periphery lies at a certain distance from the two polar faces of the ball in order that it is bordered by elevated zones;coating the whole of the spherical outer surface with a layer of hard matter;and machining the layer over a depth such that this layer disappears completely on the elevated zones and remains only in the depression.The invention also relates to a ball employed in this process.
Abstract: A connecting rod for the control and/or transmission of force, particularly for use in aeronautical construction, comprises a tubular body formed of high-strength fibres bonded together by polymerized epoxy resin. The body has frusto-conical end portions each surrounding a frusto-conical skirt portion of an end member which is adapted to receive coupling means. A ferrule, also formed of bonded fibres, is provided to tighten each frusto-conical end portion of the body against the frusto-conical skirt portion of the corresponding end member.
