Abstract
1275144 Rolling teeth PRECISION GEAR MACHINES & TOOLS Ltd 25 Aug 1969 42284/69 Heading B3M Teeth are rolled on a cylindrical workpiece 1 by a single rotatable rolling tool 2, the axes of the workpiece and tool being in parallel planes but at an acute angle to one another, and the pitch cylinders of the workpiece and tool meeting at a point of contact. By suitably arranging the angle, spur or helical teeth can be rolled. The workpiece, which may be a gear blank with precut teeth or a splined shaft, can be traversed relative to the tool. The direction of traverse can be axially of the workpiece, at right angles to its axis or at an intermediate angle. In place of traversing movement, a plunge feed of the tool may be used and the teeth of the tool have a concave pitch surface. To provide crowned teeth on the workpiece, the workpiece can be rocked about an axis perpendicular to its rotational axis during rolling. Tapered teeth may be provided by arranging the axes of the workpiece and tool in a non-parallel relationship. To roll one flank of the teeth on the workpiece preferentially compared with the opposite flank, the workpiece can be braked during rolling.
