ABSTRACT:
A device for dressing a grinding wheel for form grinding of helically toothed involute cylindrical gears comprises a straight edge rolling on an arcuate guide, and a guideway adjustable to the base helix angle of the gear being ground is given an involute movement by the straight edge and guides a tool-holder slide carrying a pointed dressing tool. A pivot member participates in the pivoting component of the straight edge movement, and for modifying the dressing tool path by moving the slide along said guideway there is a crank gear comprising a first crank slide rectilinearly displaceable by the pivoting of said pivot member, a crank on a fixed pivot and connected to said first crank slide and a second crank slide guided parallel to said first slide and driving the tool-holder slide.
