Operation
In order to generate the relief angle and not affect the tooth shape of the processed gear after regrinding, the shape of a displacement gear is made in each section perpendicular to the axis of the gear shaper. The displacement coefficient gradually decreases from the front end to the rear end surface, and is determined by positive to negative. Gear shapers are subject to some limitations in use:
① Restriction of gear undercut: When the tooth top of the gear shaper cuts into the involute tooth shape of the root of the gear to be cut during the cutting process, it is called undercut. The less the number of teeth of the gear to be processed, the greater the possibility of undercut .
② The limitation of gear top cutting: Top cutting refers to the phenomenon that the tooth top of the cut gear enters into the tooth shape of the root of the gear shaper and is cut off.
③ Limitation of gear transition curve interference: When the gear shaper is cutting teeth, it cannot cut out the involute tooth shape on the entire tooth surface, and the gear root is the transition curve. The smaller the number of teeth of the gear-shaping cutter and the larger the coefficient of tooth profile deformation, the longer the transition curve will be. If the tooth top of the paired gear contacts the transition curve, interference will occur.
④ For the gear shaper for processing internal gears, the restriction that the top cut does not occur during the radial cutting process of the gear shaper should also be considered
