When milling teeth, because the milling cutter feeds in the direction of the helical tooth groove of the helical ring gear, the tooth shape of the milling cutter cross-section should be the same as the normal cross-section (the cross-section perpendicular to the tooth groove) of the helical ring gear. The normal tooth shape of the helical ring gear is very close to the tooth shape of a straight ring gear. The module of the straight ball mill ring gear is the same as the normal module of the helical ring gear, and the number of teeth is. Using the tooth shape of this straight gear gear to replace the normal tooth shape of the helical gear gear, the problem of studying the helical gear gear is transformed into the problem of studying the straight gear gear. We call the straight gear gear with this function the helical gear gear. The equivalent number of teeth of this spur ring gear is called the equivalent number of teeth of the helical ring gear. When copying and milling the helical gear gear, a milling cutter is selected according to this equivalent number of teeth, so as to process the normal tooth shape required by the helical gear gear. The calculation formula for the equivalent number of teeth is
/
where
is the actual number of teeth of the helical gear gear
and the helix angle on the graduation circle.
