Abstract
A device for cutting teeth in gear blanks by hob peeling, the device having a workpiece spindle for holding the gear blank, the workpiece spindle being rotationally drivable about a workpiece rotational axis, the device having a tool spindle which carries a peeling wheel having cutting edges and which is rotationally drivable about a tool rotational axis, wherein the tool spindle and the workpiece spindle may be positioned relative to one another at a fixed or variable axis intersection angle, and for the purpose of forward feed and infeed, the tool spindle is movable relative to the workpiece spindle in the radial direction and in the axial direction with reference to the workpiece rotational axis by means of positioning drives, and the device having an electronic control device for controlling the positioning drives and rotationally driving the tool spindle and the workpiece spindle at a specified rotational speed ratio, optionally with a changing phase position. In order to expand the production spectrum, it is proposed that the control device is set up or may be set up in such a way that during cutting of teeth in a coarsely precut or uncut blank, a radial emerging motion out of the gear blank is superimposed on the axial feed at the end of the feed, and/or a radial submerging motion into the gear blank is superimposed on the axial feed at the start of the feed.
