Spiral bevel Gear Theory for design and manufacturing of large spiral bevel gears for mining and other applications
Very often,
large spiral
bevel gears have less then optimized tooth contact. Most of the large
spiral bevel gears are not finished after induction hardening. Tooth
deflections significantly effect poorly design spiral bevel tooth
because of deflections during the hardening process. Commonly produced
large spiral bevel gears are often made over sized for the operating
load because of the poor design methods and poor tooth contact.
With our high-resolution tooth contact simulation
software we can often increase tooth contact area for 50% without
reduction of sensitivity to misalignments. Root area of
the tooth can be also optimized for reduction of the tension stress for
30% or more. If the tooth form is optimized for highest area of the contact
and lowest level of the root stress the size of the gear can be reduced
by 30% or more by weight, with significant cost reduction.
