Abstract:
1. A rolling apparatus for rolling a workpiece rotatable about a rotational axis, the rolling apparatus comprising: a rolling arm; an arm support for supporting the rolling arm to allow the arm to follow the workpiece as it rotates for being rolled; a first rolling head mounted on the rolling arm and including at least one roller to engage the workpiece and apply pressure thereto during a rolling operation; a second rolling head mounted on the rolling arm spaced from the first rolling head and including at least one roller to engage the workpiece and to apply pressure thereto during a rolling operation; a drive associated with the rolling arm for shifting one of the first and second rolling heads relative to the other rolling head between an open position to provide clearance between the heads for a workpiece bearing to be rolled and a closed position for undertaking the rolling operation; guide surfaces of the arm and the one rolling head that guide the shifting of the one rolling head by the drive from the open position to the closed position with the guide surface of the one rolling head engaged with the guide surface of the arm when the one rolling head is shifted to the closed position; and a backing portion of the arm that is disposed behind one of the drive for the one rolling head and the other roller head with the backing portion being integral with the arm to provide robust mounting for the one of the drive and the other rolling head for resisting reactive forces generated by the pressure applying tool head rollers in the closed position during the rolling operation of the workpiece bearing.
