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
