The
unique
operating
principles
and
flexible design
configurations
of
Harmonic  Drive transmissions make
them
ideal
for
a
wide range of
applications.
Harmonic

superior to
conventional
transmissi­ ons
in
a
number
of
ways,
including
compact size,
l

weight
,
simple
construction,
high reduction
ratios
in
a
single
stage
,
zero

lash
and  co-axia
l
input/output.
Harmonic Drive
transmissions
are
successfully
used
in industrial robots,
machine
tools,
printing machines
,
medical
equipment,
communica­ tions
equipment
,
solar energy
applications
,
and
high  precision
electronic
component production

offers
high

Zero
Backlash
Harmonic
Drive
gearing
may
operate
with
essentially
zero
backlash between
mating
teeth
because

High
Single-Stage
Reduct

With
only
three
basic
elements
the
single-stage
reduction
ratios
range f
r
om
50:1
to
320:1
within
the
same
envelope.
High
Efficiency
Operating
efficiencies
of
up
to
85%
can
be
obtained.
Ratings
are based
on
actua
l
shaft-to-shaft
tests.
Back

Harmonic
Driv

are
reversib

and
can
be
back

.
Minimal
Wea
r
,
Long
Li
fe
In
Harmonic
Drive
gearing
the
teeth
come
into
contact
with
an
almost pure
radial
motion
,
and
have
essentially
zero
sliding
velocity
,
even
at high
input
speeds.
Tooth
friction
losses
and
wear
are
thus
negligible.
Improved
Torsional
Stiffness
Soft
wind-up
in
the
low torque
region
has
been
reducted
to
achieve high
overall

.
The
soft
wind-up
characteristics
are also
subject
to
improvement
on
a
custom
basis.
