Abstract: A rolling-element bearing with line contact includes bearing inner and outer parts having running surfaces, and at least one rolling element is disposed between and makes line contact with the bearing inner and outer parts. A width of the outer running surface and/or a width of the inner running surface is narrower at least in a first circumferential partial region than a length of the rolling-element, and in the first partial region the bearing outer part running surface and/or the bearing inner part running surface extends obliquely to a rolling direction of the at least one rolling element.

Abstract: A radial bearing assembly for supporting an outer part with respect to an inner part, which parts are rotatable relative to each other about a common longitudinal axis, the radial bearing assembly including a bearing seat formed on the outer part or on the inner part and having a width that varies over a circumference of the bearing seat, and assembly including at least one rolling-element in line contact with the bearing seat. The bearing seat includes at least one interruption configured such that the at least one rolling element is supported by the bearing seat along the entire circumference of the radial bearing assembly and such that at least part of the at least one rolling element makes line contact with the bearing seat along the entire circumference of the radial bearing assembly.

Abstract: A rolling-element bearing with line contact includes a bearing outer part having a running surface, a bearing inner part having a running surface, and at least one rolling element disposed between the bearing inner part and the bearing outer part. The at least one rolling element is configured to make line contact with the running surface of the bearing outer part and with the running surface of the bearing inner part, and either or both of the bearing inner and outer parts includes at least one lubricant channel that is at least partially open to the running surface.

Abstract: The present invention relates to a mechanical system with a one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element which are able to move one with respect to the other in rotation about a central axis and delimit an annular housing radially to the central axis, a one-way clutch device arranged in the annular housing, and at least one rolling bearing arranged in the annular housing. The mechanical system is characterized in that the rolling bearing comprises at least one pressed ring distinct from the constituent elements of the one-way clutch device. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.

Abstract: The invention relates to a one-way clutch mechanical system, in particular a pulley-assembly for a motor vehicle alternator. The one-way clutch mechanical system includes an inner element and an outer element, which are movable relative to one another in rotation around a central axis (X1) and delimits an annular housing between them. The system further includes a one-way clutch device positioned in the annular housing, a member for damping a relative rotational movement between the inner and outer elements and for transmitting torque to the one-way clutch device, which is also positioned in that annular housing. The damping and torque transmission member is axially offset relative to the one-way clutch device, along the central axis (X1).

Abstract: The present invention relates to a mechanical system with one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element able to move one relative to the other. These elements delimit an annular housing including a one-way clutch device and at least one rolling bearing positioned beside the one-way clutch device. The mechanical system is characterized in that the one-way clutch device is lubricated by a lubricant of a first type, in that the rolling bearing or bearings are lubricated by at least one lubricant of a second type, and in that the lubricant of the first type and the lubricant of the second type are different from and compatible with one another. The invention also relates to an alternator comprising such a system configured as a pulley, and to a method of manufacturing such a mechanical system.
