The paper presents the method which evaluates the gear ratio error of envelope chain and indexing chain spiral-bevel-gear generator ZFTKK250X5 in the Gleason system. The elements in power transmission chains are gear transmitters, which are subject to kinetic errors, pitch errors, cumulative pitch errors, etc . |
