2 FLENDER Standard Couplings General information Overview Coupling suitable for use in potentially explosive atmospheres. Complies with the current ATEX Directive for: II 2 G T3 D160 C X II 2 G T4 D120 C X (Type EST is not available in Ex version.) ELPEX-S couplings are highly torsionally flexible and because of their low torsional stiffness and damping capacity are especially suitable for coupling machines with a highly non uniform torque pattern. Standard ELPEX-S coupling types are designed as flange-shaftconnections or shaft-shaft connections. Application-related types can be implemented on request. Benefits The ELPEX-S coupling is suitable for horizontal and vertical mounting positions or mounting at any required angle. The coupling parts can be arranged as required on the shafts to be connected. ELPEX-S couplings are especially suitable for reversing operation or operation with changing directions of load. The rubber disk elements are fitted virtually without backlash and give the coupling linear torsional stiffness, i.e. the torsion stiffness remains constant even when the load on the coupling increases. There are 4 different rubber element versions with different grades of torsional stiffness available for each size from stock. On certain types the flexible rings can be changed without having to move the coupled machines. If substantial overload occurs, the rubber disk element of the coupling is irreparably damaged, the coupling throws the load and thus limits the overload for particular operating conditions. The coupling can be inserted and fitted blind e.g. in a bell housing. There are outer flanges with different connection dimensions available for each coupling size. Application The ELPEX-S coupling is available as a catalog standard in 12 sizes with rated torques of between 330 Nm and Nm. The coupling is suitable for ambient temperatures of between -40 C and +120 C. Design The rubber disk element is vulcanized onto a flange on the inside diameter. The flange can mount e.g. a Taper clamping bush or a hub. On its outer diameter the rubber disk element has driving teeth, which are inserted into the outer flange. The torque is transmitted positively between the rubber disk element and the outer flange. In the type for shaft-shaft connection the outer flange is screwed to a flange hub mounted on a machine shaft. Materials Type EST Types E. and ESD.

Because the different rubber versions enable the torsional stiffness to be adjusted to meet requirements, the coupling is also suitable for drives which require a specific and preferably precalculated torsional vibration behavior setting.

4 FLENDER Standard Couplings General information Further application-related coupling types are available. Dimension sheets for and information on these are available on request. The following versions have already been implemented a number of times: ELPEX-S coupling with brake drum, brake disk or flywheel mass ELPEX-S coupling with axial backlash limiter ELPEX-S coupling with adapter ELPEX-S coupling with bearing for mounting a cardan shaft ELPEX-S coupling for engaging/disengaging during standstill ELPEX-S coupling as part of a coupling combination ELPEX-S coupling with fail-safe device Fail-safe device of ELPEX-S coupling G_MD10_XX_00023 The ELPEX-S coupling can also be designed with a fail-safe device. If the rubber disk element fails, the coupling can continue operating in emergency mode for a short time. This option is frequently required e.g. in the case of marine drives. If the rubber disk element fails, cams transmit the torque from the inner and outer parts of the fail-safe device. In normal operation the torsion angle of the rubber disk element is smaller than the gap between the cams, so there is no metalmetal contact. Function The ELPEX-S coupling's transmission characteristic is determined essentially by the rubber disk element. The torque is transmitted positively between the rubber disk element and the outer flange. The outer flange can be bolted to e.g. a diesel motor or compressor flywheel. Configuration Coupling selection The ELPEX-S coupling is especially suitable for rough operating environments. An application factor lower than that in catalog section 3 is therefore sufficient for all applications. In the case of machines which excite torsional vibration, Siemens urgently recommends carrying out a torsional vibration calculation or measuring the coupling load occurring in the drive. Coupling load in continuous operation Application factor FB Torque characteristic of the driven machine Torque characteristic uniform with non uniform very rough of the driving machine moderate shock loads Electric motors, hydraulic motors, gas and water turbines Internal combustion engines Examples of torque characteristic in driven machines: uniform with moderate shock loads: generators, fans, blowers non uniform: reciprocating compressors, mixers, conveyor systems very rough: crushers, excavators, presses, mills Temperature factor FT Coupling Rubber version Elastomer material NR = natural-synthetic rubber mixture VMQ = silicone rubber Temperature T a on the coupling to to to 60 C -30 C +50 C to 70 C to 80 C to 90 C to 100 C to 0 C ELPEX-S,, WN NR ELPEX-S NX VMQ to 120 C Select coupling size with: T KN T N FB FT /4 Siemens MD

5 FLENDER Standard Couplings General information Coupling load under maximum and overload conditions The maximum torque is the highest load acting on the coupling in normal operation. Maximum torques at a frequency of up to 25 times an hour are permitted and must be lower than the maximum coupling torque. Examples of maximum torque conditions are: Starting operations, stopping operations or usual operating conditions with maximum load. T Kmax T max FT Overload torques are maximum loads which occur only in combination with special, infrequent operating conditions. Examples of overload torque conditions are: Motor short circuit, emergency stop or blocking because of component breakage. Overload torques at a frequency of once a month are permitted and must be lower than the maximum overload torque of the coupling. The overload condition may last only a short while, i.e. fractions of a second. T KOL T OL FT Coupling load due to dynamic torque load Applying the frequency factor FF, the dynamic torque load must be lower than the coupling fatigue torque. Dynamic torque load T KW T W FT FF 0.6 FB 1.0 Checking the maximum speed The following must apply to all load situations: n Kmax n max The maximum speed of a size depends only on the size of the outer flange (part 3). Checking permitted shaft misalignment and restorative forces For all load situations, the actual shaft misalignment must be less than the permitted shaft misalignment. Checking bore diameter, mounting geometry and coupling design The check must be made on the basis of the dimension tables. On request, couplings with adapted geometry can be provided. Checking shaft-hub connection Please refer to catalog section 3 for instructions. Checking temperature and chemically aggressive environment The permitted coupling temperature is specified in the Temperature Factor FT table. In the case of chemically aggressive environments, please consult the manufacturer. Frequency of the dynamic torque load f err 10 Hz frequency factor FF = 1.0 Frequency of the dynamic torque load f err > 10 Hz frequency factor FF = (f err /10 Hz) Operation in potentially explosive environments is subject to the following restriction: Operation with low fatigue load The fatigue torque T KW must be reduced by 70 %. In these particular operating conditions the coupling satisfies the requirements of temperature class T4 D120 C. Operation with medium fatigue load The fatigue torque T KW must be reduced by 50 %. In these particular operating conditions the coupling satisfies the requirements of temperature class T3 D160 C. Type EST is not permitted for application in potentially explosive environments.
