POWER TRANSMISSION | GEARBOXES
ALL THE GEAR… A view of some of the latest
gearbox technologies that increase
performance and e ciency to have
reached the market.
There have been
a number of
developments
in the eld of
industrial gearboxes
that offer designers
improved options in
terms of performance
and ef ciency.
Among these is a
robotics and factory
automation, applications
for the versatile motors
include electronic and
semiconductor equipment,
medical equipment...
laser processing and
new range of right-angled
planetary gearboxes is
now available from Motor
Technology for a wide range of
industrial applications. Manufactured
by Italian rm, Tramec, the TEP
range is based on the company’s
long-established EP range of generalpurpose
planetary gearboxes.
Right-angled gearboxes are
frequently used where there are
space constraints on a machine, often
machines with high axis counts, such
as slitters and winders, printing and
packaging machines, handling and
robotics, etc.
Currently available in
four frame sizes, 55, 75, 90,
and 120, in one and two
stage con gurations.
Single stage
versions offer
ratios from 3:1
to 10:1, and two
stage versions
offer ratios from
12:1 to 100:1.
Backlash
ranges from 12-17
arcminutes for the
single stage and
15-20 arcminutes for
the two-stage versions.
Gearbox ef ciency
is 94% for the single-stage
type and 91% for the two
stage.
The gearboxes also
perform well in terms of
noise generated during
operation with levels
between 65 to 70dB at
3000rpm input speed. Gearbox
output torque is up to 180Nm
nominal, 290Nm peak, and with an
E-Stop torque of 600Nm.
The gearboxes are ange
compatible with Tramec’s EP series
and also offer alternative
shaft and output ange options. A
wide range of motor adapters are
available for typical servo, stepper,
DC and AC motors.
Another innovation comes from
Motion Control Products, which has
introduced compact high torque
motors with integral strain-wave
(harmonic) gearboxes.
Offering high levels of torque
and precision, the latest torque
motors have an integral strain wave
(harmonic) gearbox. With high
ef ciencies and compact sizes, they
are available in four series: MAS,
MAT, MAH and MGM.
The all-in-one MGM series has an
integral torque motor, encoder, brake
and servo drive. Delivering a high
precision of up to 60 arcseconds,
their high torque of up to 557Nm
suits them for a host of applications
demanding low noise, high torque
and precision control, such as
collaborative robot applications
for loads of up to 25kg. Integrated
servo drives for EtherCAT or
CANOpen enable the units to
interface with most mainstream
controllers on the market.
A hollow shaft simpli es system
design by allowing the
passage of cables,
pipework etc.
The other series
of low-cogging,
low noise
motors have an
integrated strain wave
As well as
spray-painting
equipment
