Design
The classic design of an ARPEX couplings of the ARS-6 series is
shown in the following illustration. The plate packs are bolted al-
ternately between the flanges of the coupling hubs and the inter-
mediate spacer. Up to size 280-6 close-fitting bolts and from size
305-6 conical screw connections are used for fastening. A large
number of intermediate spacer and shafts, hubs and flanges
can be combined and thus cover a large number of possible
drive requirements.
Design of an ARPEX coupling, ARS-6 series, type NEN
Variants of the ARPEX coupling, ARS-6 series
All coupling types can be very easily combined with further stan-
dard components in the ARPEX modular system. Jumbo hubs
are used to permit larger maximum bores.
Clamping hubs transmit torque by friction without the use of par-
allel keys.
F, D and C flanges offer many different possibilities for flange
connection.
The coupling parts of the ARPEX ARS-6 series are machined on
all sides. Exceptions are H and Z spacers and intermediate
shafts. The spacers are delivered with unmachined, primed
spacer tube.
Higher torques and maximum speeds with similar coupling outer
diameters DA can be achieved with the ARPEX ARC-8/-10
series.
