Carbon fibre linear guides by Igus
When it comes to weight savings, designers rely on carbon fibre
reinforced plastic (CFRP). To meet this demands, igus has
developed a drylin W profile. A very lightweight, high stiffness
and non-magnetic CFRP. For aerospace or medical technology,
igus offers the lightest linear guide in its magnitude made of
carbon, for up to 2 000 mm stroke. Here, it is not only the
support material that is made of CFRP, but the whole rail. The
entire system is up to
40 % lighter than
aluminium and up to
60 % lighter the than
steel system.
Industries where
high dynamic
movements plays are
important, such as
robotics, are
increasingly utilising
CFRP components.
The high profile geometry of the CFRP rail enables an attachment
by means of clamping jaws, which makes a complicated
mechanical reworking superfluous. Moreover, the rail with high
profile is the basis for a completely metal-free toothed belt axis,
which is available in lengths up to 1000 mm. Here a deflection
consisting of a carbon axis, a plastic gear and xiros plastic ball
bearings from the igus range is used. Thus, it can be used
without restrictions in X-ray equipment in medical technology.
The carbon guide, does not require any external lubrication and
thus is maintenance free.
Expansion of product
portfolio at Desch
The demand for couplings with compact sized and high
power transmission rate is continuously increasing. With
requirements for high power density systems are
increasing the manufacturer are dealing with extremely
high levels of torque. Consequently, gear couplings are
becoming more and more significant. They provide
extremely high torque capacities and can also cope with
extremely high peak loads. The Desch GC gear coupling
is a double-cardanic shaft coupling with positive torque
transmission via the toothing in the mesh. The convex
toothing of the hub enables compensation of radial, axial
and angular shaft displacements. The coupling is
normally installed horizontally. Special customized
versions, can be installed vertically without any problems.
The bandwidth of Desch GC gear coupling sizes
ranges from 50 to 1 000, permitting torque transmissions
from 1,920 to 8,000,000 Nm, to fit shaft diameters from 20
to 1 000 mm. Compared to
other gear couplings, the
Desch GC’s main distinguishing
feature is an
extremely high power
density combined with
compact design.
