Abstract

Adjusting device for an oscillating workpiece. In one type of gear grinding machine, there is provided means for effecting oscillation of the workpiece simultaneously and in synchronism with reciprocation thereof in order to enable a substantially involute curve to be ground onto the workpiece by a grinding wheel which is fixed excepting for its rotation. In such machine, this oscillation is created by at least one cam fixed to the workpiece spindle together with at least two bands fixed at one of their respective ends to such cam and at the other of their respective ends to a fixed portion of the machine with the bands being wrapped in opposite directions at least partially around such cam. Thus, sidewise reciprocating movement of the workpiece spindle effects oscillation of same in a known manner according to the curve provided on said cams. In the present invention, there is provided means for imposing a further controlled movement onto the workpiece spindle either transversely or longitudinally of its axis, or both, in order to provide modification as desired of the surface being ground onto a workpiece tooth and particularly to cause such surface to deviate in a desired manner…
