Description
Description
of
Helical
Gear
A
helical
gear
is
a
cylindrical
gear
whose
tooth
line
is
inclined
at
a
certain
angle
to
the
axis.
It
achieves
meshing
transmission
through
spiral
tooth
surfaces,
and
the
angle
between
the
tooth
direction
and
the
axis
is
called
the
helix
angle.
Features
of
Helical
Gear
-
High
contact
ratio:
Multiple
pairs
of
teeth
are
engaged
simultaneously,
resulting
in
better
transmission
smoothness
compared
to
spur
gears.
-
Low
shock
and
vibration:
It
can
significantly
reduce
noise,
making
it
suitable
for
high-speed
operation
conditions.
-
Even
load
distribution
on
single
tooth:
This
enhances
the
load-bearing
capacity
and
prolongs
the
service
life.
Working
Principle
of
Helical
Gear
When
the
driving
gear
rotates,
the
spiral
tooth
surface
gradually
contacts
the
driven
gear
along
the
tooth
width
direction.
The
load
is
transmitted
through
multiple
tooth
surfaces,
and
the
length
of
the
line
of
action
changes
dynamically
during
rotation,
thus
achieving
continuous
and
smooth
power
transmission.
Application
of
Helical
Gear
Metal
helical
gears
are
commonly
used
in
industrial
machinery,
aerospace
and
other
high-load
transmission
fields;
engineering
plastic
helical
gears
are
mostly
used
in
office
equipment,
medical
devices,
toys
and
other
occasions
where
noise
and
weight
requirements
are
higher.
