DESCRIPTION OF DISCS
The fundamental elements of this torsionally rigid coupling are the disc packs, built from a series of stainless steel discs type AISI 304-C,
connected by steel bushes. This disc pack is connected in an alternate way to the hub
fl
ange or the eventual spacer, by using screws in steel
class 10.9 and the relevant self-locking nuts.
With reference to the con
fi
gura
Ɵ
on, the disc packs can be:
A)
Con
Ɵ
nuous ring disc pack for 6 screws (coupling sizes 1-7)
B)
Sec
Ɵ
onal disc pack for 6 screws (coupling sizes 8-11)
C)
Sec
Ɵ
onal disc pack for 8 screws (coupling sizes 12-15)
Assembly example with internal and external locking bushes.
Designed to suit applica
Ɵ
ons where high reliability, precision and an op
Ɵ
mum weight/power ra
Ɵ
o is required; ideally suited for applica
Ɵ
ons
with high speeds and power, also o
ff
ering low overhung loads when using the spacer version.
This coupling is composed of three main items: the two fully turned hubs, made in steel UNI EN10083/98 and the disc pack, in stainless steel
AISI 304 C with connec
Ɵ
on screws in steel class 10.9. In the “double” version, GTR/D, there is also a spacer made to length, also built in steel
UNI EN10083/98,
fi
xed between the hubs and the two disc packs.
All the components of GTR couplings, except the spacer (GTR/D and GTR/DBSE) are made and sta
Ɵ
cally balanced in class DIN ISO 1940-1:2003
Q 6.3, before the machining of the keyway.
In accordance to the speci
fi
c need of the applica
Ɵ
on, it is possible to make sta
Ɵ
c or dynamic balancing on each separate component or on the
coupling, fully assembled to customer requirements.
