DISPOSITIF POUR L'AJUSTEMENT AXIAL D'UN CORPS ROTATIF, PAR EXEMPLE UN PIGNON

摘要

A bearing assembly rotatably supporting a shaft journal having a gear wheel at one end in a cylindrical seat in a housing comprising a one-piece outer ring having threads on its outer periphery cooperating with threads in the cylindrical seat. A plurality of circumferentially spaced openings are provided in the outer axial end face of the outer ring to accommodate a turning tool having projections corresponding to the openings to permit axial adjusting movement of the bearing assembly relative to the housing. The bearing assembly further includes an inner race ring on the shaft journal, two rows of rolling elements in the annular space between the rings spaced closely relative to one another. One of the rows comprises rollers having axes inclined at an angle to the bearing axis disposed adjacent the gear wheel and the other row comprises balls which roll against raceways in the rings to provide angular contact which are disposed at the opposite end of the shaft journal.
