FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARC-8/-10 Series © Siemens AG 2015 General information ■ 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.
6 ■ 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 • Rotary furnaces • Stirrers 1) Protected by patent in a number of countries on the date of creation of this catalog. 6/27 Siemens MD 10.1 · 2015
