Abstract

Apparatus for the manufacture or machining of gears with a toothed tool having abrasive working surfaces, in which workpiece and tool, during rotation, are supported by the tooth system of a guide-gear pair. The apparatus works with a single-flank contact between workpiece and tool, whereby for changing the tooth flanks which contact one another, one member of the drive chain can be rotated relative to the other members a preselectable or adjustable amount.
