iron gears are subcategory of gears.
Cast Iron Gears is also
known as grey iron and provides good stability,
smooth surface finish. The color of surface
is used to identify an alloy. White cast
iron gears is one which allows
the cracks to pass in straight direction
and grey iron is one which initiates countless
cracks as the material breaks and passing
crack deflect graphitic flakes.
Cast iron is brittle in
nature. They have good fluidity, wear resistance,
low melting point, and excellent machinery,
cast iron gears become
a fabulous engineering material and used
in pipes, automotive industry parts, machines
like cylinder blocks, gearbox, and cylinder
A method called welding of fabrication
is used I cast iron by joining metals. This
method is used for structural purpose. By
heating a blanket at a temperature that
is compatible to the blanket and forming
a tooth part, a cast iron gears
can be made.
Many ductile iron is cast iron as it large
amount of carbon in the matrix. Gears
that are made up of cast iron gears
rely on low manufacture cost and easy to
use with high damping. They are used in
commercial gears. Cast iron gears
has variety of advantages like long service
life; ability to obtain high hardness, production
cost is low.
