WAVES
DAMPENED
High speeds and high
waves not only make
for a lot of fun on board
high-speed boats, they can also
be dangerous as passengers
experience a physical shock every
time the boat's hull strikes the
water. Vibration-dampening seats
with bearings that absorb these
shocks are therefore called for.
Designers are able to rely on
wear-resistant igus linear bearing
technology, distributed by
Treotham, thanks to the use of
tribo-polymers that are lubricationfree,
maintenance-free and
corrosion-free.
Waves, a light breeze and sunshine
are the conditions that guarantee
an enormous amount of fun on
high-speed boats. To make sure
of this, designers need to install
not only a powerful motor but also
seats that give the crew a feeling of
safety and comfort when travelling
on the water. High waves and high
speeds require cushioned and
lightweight components such as
vibration-dampening seats. The
reason is that the passengers on
board are subjected to repeated
impacts when the hull of the
boat hits the water. Powerful
COMPACT,
COST-EFFECTIVE:
Fast automation in confined
installation spaces: igus has
now developed an extracompact
toothed belt axis based
on its flat drylin N linear system. The
new axis consists of a completely
standard fitment of components
and is thus easily assembled within
a few minutes and cost-effective.
Equipped with motor and control,
the new system can carry loads of
up to 20 Newton and a translation
of 60 millimetres per revolution.
From the lubrication-free plain
bearing and the maintenance-free
linear guide up to the completely
ready-to-install linear robot, igus
develops solutions for the industry
with its plastics - either as a single
part or as a system. With the help
of its linear construction kit, the
motion plastics specialist has
combined its drylin N low-profile
linear guide with a toothed belt
and has now developed the new
cost-effective drylin ZLN toothed
belt axis as standard. Whether in
vending machines, service robotics
or even in automation systems, the
new compact toothed belt system
can be installed quickly and easily
in the smallest of spaces. The
flat drylin N linear guide ensures
compact construction, which is
just 27 millimetres high and 40
millimetres wide. The toothed
belt mounted on ball bearings
enables high speed dynamics.
With the combination of lowprofile
linear guide and toothed
belt, loads up to 20 Newton can
be moved vertically at a ratio of
60 millimetres per revolution. By
using high-performance polymers
in the sliding carriage, users can
completely dispense with lubricants
and thus the maintenance of the
unit. Moisture, dirt and dust are
no problem for the drylin ZLN:
great advantages, especially for
machines that are in use 24/7.
The new toothed belt axis for
low cost automation consists of
standard components from the
drylin modular system that can
be fitted together and assembled
quickly. Thus, the new axis is not
only lightweight due to the use of
plastic components, but also costeffective
and delivered quickly. A
completely ready-to-install drylin
ZLN can be ordered with NEMA
stepper motors or with EC/BLDC
DC motors as well as a suitable
dryve control system. The new,
cost-effective toothed belt axis can
be delivered from Treotham in the
desired size with a maximum length
of up to 750 millimetres already
from 24 hours.
impacts like this can quickly lead
to serious injury to the spine or
internal organs. Such seats must
therefore rest on wear-resistant
bearings and rails that can absorb
the forces involved. This is why
developers of high-speed boats
such as Kaj Naval from Poland or
Cobra Seats Technology Ltd from
Great Britain use lubrication-free
and maintenance-free igus linear
bearing technology made of highperformance
plastics.
The Polish company Kaj Naval has
been developing seats for motor
boats for seven years. For the
latest type of seat, the designers
are using a drylin W linear guide
for the spring-mounted shockabsorbers.
This guide ensures
that the seats slide about gently
even at high speeds, absorbing the
vibrations of the waves. The guide
carriage has no lateral clearance
due to the use of sliding elements
made of tribo-polymers and,
even after a long operating time,
does not show any signs of wear.
Another advantage: the corrosionfree
solution from Treotham is
maintenance-free, lubricationfree
and considerably lighter
than metallic alternatives like
recirculating ball bearing guides.
