FLENDER Standard Couplings Coupling Preselection and Options © Siemens AG 2011 Selection of the coupling series 3 ■ Selection and ordering data The coupling series is frequently determined by the driven machine and the design of the drive train. Common selection criteria are listed below and assigned to coupling properties, which are used to select the coupling series. Additionally, the price of the coupling and availability are important criteria for determining the coupling series to be used. The FLUDEX series operates positively and transmits the torque with the aid of a flowing oil or water filling. FLUDEX couplings are used to reduce starting and/or overload torques. During starting, the motor may, for example, run up within a very short time; because of the FLUDEX coupling, the drive train with the driven machine may accelerate after a delay and without increased torque load. Selection criterion ZAPEX ARPEX N-EUPEX N-EUPEX DS Torque range Speed range Rated coupling torque T KN in Nm Peripheral speed v max = DA ⋅ n max /19100 850 ... 7200000 92 ... 1450000 The FLUDEX coupling cannot compensate for shaft misalignment and is therefore designed in combination with a displacement coupling, a cardan shaft or a belt drive. The displacement coupling may be selected in accordance with the criteria described below. 19 ... 62000 19 ... 21200 RUPEX BIPEX ELPEX-B ELPEX-S ELPEX 200 ... 1300000 13.5 ... 3700 24 ... 14500 330 ... 63000 60 100 36 36 60 36 35 66 60 Torque load uniform non uniform rough – – – very rough – – – – Installation and alignment Rigid installation, well aligned Rigid installation, – – – – – roughly aligned Flexible installation – – – – – Torsional stiffness Torsionally rigid – – – – – – – Torsionally flexible – – – – Highly flexible – – – – – – Torque transmission Free of torsional backlash – – – – – Low torsional backlash – – – – – Overload withstand – – capability Assembly Plug-in assembly – – – with Taper clamping bushes – – – – Maintenance Wear parts easily – dismountable Maintenance-free – – – – – – – Low-maintenance - interval – 1year Environment ATEX 94/9/EC Approval – – – Operating temperature range -20 ... +80 °C -40 ... +280 °C -50 ... +100 °C -30 ... +80 °C -50 ... +100 °C -30 ... +80 °C -50 ... +70 °C -40 ... +120 °C Chemically aggressive Coupling material Cast iron – – Steel – – – Stainless steel – – – – – – Add-on parts / types Adapter – Brake disk – – Brake drum – – Axial backlash limiter – – – – Shiftgear – – – – Flange type – – Flange to SAE J620d – – 1600 ... 90000 -40 ... +80 °C (450) 655-7447 info@pt-dstech.com www.dstech.ca 1275 Newton, local 15 Boucherville, Qc, Canada, J4B 5H2 Standard On request – Not possible 3/2 Siemens MD 10.1 · 2011
© Siemens AG 2011 FLENDER Standard Couplings Coupling Preselection and Options Selection of the coupling series Typical coupling solutions for different example applications The specified application factors are recommendations; regulations, rules and practical experience take priority as assessment criteria. No application factor need be taken into account with FLUDEX couplings. In the case of highly flexible couplings of the ELPEX, ELPEX-S and ELPEX-B series, deviating application factors are stated in the product descriptions. 1275 Newton, local 15 Boucherville, Qc, Canada, J4B 5H2 (450) 655-7447 info@pt-dstech.com www.dstech.ca Example applications Application FLUDEX ZAPEX ARPEX N-EUPEX RUPEX BIPEX ELPEX-B ELPEX-S ELPEX factor FB Electric motor without gear unit Centrifugal pumps 1.0 ... 1.5 – – Piston pumps 1.5 ... 2.0 – – Vacuum pumps 1.5 ... 1.75 – Fans 1.5 ... 2.0 – Blowers 1.5 ... 2.0 – Frequency converters / generators 1.25 ... 1.75 – – Reciprocating compressors 1.75 ... 2.5 – – Screw-type compressors 1.5 ... 1.75 – Internal-combustion engine without gear unit Generators 1.75 ... 2.5 – – – Pumps 1.5 ... 1.75 – – Fans 1.75 ... 2.5 – – – Hydraulic pumps, excavators, construction 1.5 ... 1.75 – machines Compressors / screw-type compressors 1.5 ... 1.75 – Agricultural machinery 1.75 ... 2.5 – Other Turbine gear units 1.5 ... 1.75 – – – – – – Hydraulic motor - gear unit 1.25 ... 1.5 – Electric motor with gear unit Chemical industry Extruders 1.5 ... 2.0 – – – Pumps - centrifugal pumps 1.0 ... 1.5 – – Pumps - piston pumps 1.75 ... 2.5 – Pumps - plunger pumps 1.5 ... 1.75 – Reciprocating compressors 1.75 ... 2.5 – Calenders 1.5 ... 1.75 – – Kneaders 1.75 ... 2.5 – Cooling drums 1.25 ... 1.5 – – – Mixers 1.25 ... 1.5 – – – Stirrers 1.25 ... 1.5 – – Toasters 1.25 ... 1.5 – – – – Drying drums 1.25 ... 1.5 – – – Centrifuges 1.25 ... 1.5 – – Crushers 1.5 ... 2.5 – – Power generation and conversion Compressed air, reciprocating compressors 1.75 ... 2.5 – – Compressed air, screw-type compressors 1.25 ... 1.5 – – Air - Blowers 1.5 ... 1.75 Air - Cooling tower fans 1.5 ... 1.75 – Air - Turbine blowers 1.5 ... 1.75 – – – – – – Generators, converters 1.25 ... 1.5 – – – – – Welding generators 1.25 ... 1.5 – – – – – – Metal production, iron and steel works Plate tilters 1.5 ... 2.0 – – – – Ingot pushers 1.75 ... 2.5 – – – – Slabbing mill 1.75 ... 2.5 – – – – Coiling machines 1.5 ... 2.0 – – – – Roller straightening machines 1.5 ... 2.0 – – – – Roller tables 1.75 ... 2.5 – – – – Shears 1.75 ... 2.0 – – – – Rollers 1.75 ... 2.0 – – – – Preferred solution Possible, less common – Uncommon 3 Siemens MD 10.1 · 2011 3/3
