Coated Gear Shaving Cutter
Common
normal
length
The
external
gear
is
the
common
normal
distance
measured
between
the
two
outer
tooth
surfaces
of
adjacent
teeth;
the
internal
gear
is
the
common
normal
distance
measured
between
the
two
outer
tooth
surfaces
of
several
adjacent
tooth
slots,
which
is
called
the
common
normal
length.
For
involute
spur
gears,
the
common
normal
length
is
calculated
in
the
end
plane,
and
the
calculation
formula
is:
Wt=mtcosat[(k-0.5)x+zinvat]+2mtxtsinat
(x
should
have
its
own
symbol,
k
is
the
number
of
cross
teeth).
The
involute
helical
tooth
(or
herringbone
tooth)
cylindrical
gear
is
measured
in
the
normal
plane,
and
its
value
is:
Wn=Wtcosβb.
The
length
of
the
common
normal
line
is
an
important
indicator
for
checking
the
depth
of
cutting
teeth
and
determining
the
level
of
accuracy.
The
length
of
the
common
normal
can
be
directly
checked
from
the
relevant
table.
