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 is an angular-contact bearing and comprises at least one pressed ring comprising means of attachment of the rolling bearing to the first element or the second element. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.
