General information
6
■
Overview
Coupling can be designed for use in potentially explosive
atmospheres in accordance with the current ATEX Directive.
■
Benefits
ARPEX couplings of the ARC-8/-10 series are outstanding for
their robust construction. They have been optimized for high
torques combined with high speeds. The patented
1)
conical
screw connection ensures reliable torque transmission by a true
positive fit and is designed to be extremely easy to fit. Couplings
can be designed for use in potentially explosive atmospheres in
accordance with the current ATEX Directive.
■
Application
ARPEX couplings of the ARC-8 and ARC-10 series are output-
and speed-optimized coupling solutions. Power transmission is
by means of patented
1)
conical screw connections and plate
packs of the octagonal and decagonal types. Torques of be-
tween 8.5 and 1450 kNm can be transmitted at a permitted an-
gular misalignment of 0.2° to 0.4°. The closed flange shape and
a compact construction permit high peripheral speeds and high
speeds. On most types, the intermediate spacer can be radially
fitted without moving the connected units.
Main areas of application for the ARC-8/-10 series:
•
Paper-making machines
•
Printing machines
• Compressors
•
Fans and blowers
• Generators
• Presses
• Conveyors
•
Crane systems
• Pumps
• Mills
•
