Description
Herringbone
Gear
Description:
The
herringbone
gear
is
a
type
of
gear
composed
of
left
and
right
symmetrical
helical
teeth.
Its
tooth
profile
is
arranged
in
the
shape
of
a
"person"
character,
equivalent
to
the
combination
of
two
helical
gears
with
opposite
rotational
directions.
Key
Features
-
It
adopts
a
double
helical
tooth
design,
and
usually
has
a
retraction
groove
in
the
middle
(or
a
seamless
continuous
structure).
-
The
contact
line
on
the
tooth
surface
is
in
the
shape
of
a
"V",
and
the
meshing
process
is
smooth
with
no
axial
thrust.
Technical
Advantages
-
Eliminate
axial
force:
The
axial
forces
of
the
left
and
right
helical
gears
cancel
each
other
out,
reducing
the
load
on
the
bearings
and
making
the
system
more
stable.
-
High
load-bearing
capacity:
The
double
helix
structure
ensures
a
more
even
distribution
of
the
load,
making
it
suitable
for
high-power
transmissions.
