7 ADAPTATION HUBS TUBES TORQUE LIMITERS We offer all standard connections, such as evolute splines, flange connections, clamping sets, keyway connections and oil press fits. In addition, CENTA has developed the CENTALOC clamping hub, a shafthub-connection, which is completely free of backlash and has proven itself in thousands of applications. The clamping system prevents wear and tear due to fretting corrosion or deflection of the gearing and is available for all couplings. FLANGES The is available for all SAE flywheels as well as for non-standard flywheels. Flanges can be obtained for all connections and can be adapted to any existing drive or PTO elements as desired. The homokinetic version of the can be delivered in any requested length and thereby adapted to specific mounting conditions. Short shafts are made with tubes of round steel, longer shafts (up to 6 metres and special designs of even greater length) are bridged by a thin-walled precision steel tube. In addition, CENTA has developed light-weight drive shafts made of carbon-fibre reinforced plastic. The rigidity and stability is comparable to steel, but the weight is significantly less, which is an advantage especially for bend-critical applications. For applications which require extremely high insulation values, the can be delivered with a glass-fibre tube. Load holding torque limiters are available for all designs, suitable for mounting either in the middle tube as well as on the generator shaft. Supplied with pre-set slip-through torque and individual calibration protocol. CF-A-EN PAGE 7 PUBLISHED 0. March 017 MAIN MENU CHECK FOR UPDATES

32 1,0 0,8 0,6 St PKV EXPLANATION OF THE TECHNICAL DATA 0,4 0, C Size Rubber quality Maximum torque Continuous vibratory torque Permissible Power Loss Shore A [knm] TKW [knm] PKV [kw] or [W] This spontaneously selected figure designates the size of the coupling. This figure indicates the nominal shore hardness of the elastic element. The nominal value and the effective value may deviate within given tolerance ranges. 3 Nominal torque TKN [knm] Average torque which can be transmitted continuously over the entire speed range. TKmax This is the torque that may occur occasionally and for a short period up to times and may not lead to a substantial temperature rise in the rubber element. In addition the following maximum torques may occur: TKmax = 1,8 x TKN TKmax1 = 1,5 x TKN TKmax = 4,5 x TKN Peak torque range (peak to peak) between maximum and minimum torque, e.g. switching operation. Temporary peak torque (e.g. passing through resonances). ΔTKmax or TKmax1 may occur.000 times alternating or times swelling. Transient torque rating for very rare, extraordinary conditions (e.g. short circuits). Amplitude of the continuously permissible periodic torque fluctuation with a basic load up to the value TKN. The frequency of the amplitude has no influence on the permissible continuous vibratory torque. Its main influence on the coupling temperature is taken into consideration in the calculation of the power loss. Operating torque TBmax [knm] The maximum operating torque results of TKN and TKW. Damping of vibrations and displacement results in power loss within the rubber element. The permissible power loss is the maximum heat (converted damping work into heat), which the rubber element can dissipate continuously to the environment (i.e. without time limit) without the maximum permissible temperature being exceeded. The given permissible power loss refers to an ambient temperature of 30 C. If the coupling is to be operated at a higher ambient temperature, the temperature factor St PKV has to be taken into consideration in the calculation. The coupling can momentarily withstand an increase of the permissible power loss for a short period under certain operation modes (e.g. misfiring). PKV30 [kw] or [W] For a maximum period of 30 minutes the double power loss PKV30 is permissible. CENTA keeps record of exact parameters for further operation modes. CF-A-EN PAGE APP- PUBLISHED 0.

33 1 1,0 0,9 St CTdyn 0,9 St ψ 0,8 EXPLANATION OF THE TECHNICAL DATA 0,8 0,7 Sh 60 Sh 70 Sh 0,7 0,6 Sh 60 Sh 70 Sh 0, C C Dynamic torsional stiffness Relative damping Speed Permissible axial displacement CTdyn [knm/rad] ψ [min -1 ] [mm] The dynamic torsional stiffness is the relation of the torque to the torsional angle under dynamic loading. The torsional stiffness may be linear or progressive depending on the coupling design and material. The value given for couplings with linear torsional stiffness considers following terms: Pre-load: % of TKN Amplitude of vibratory torque: 5% of TKN Ambient temperature: 0 C Frequency: 10 Hz For couplings with progressive torsional stiffness only the pre-load value changes as stated. The tolerance of the torsional stiffness is ±15% if not stated otherwise. The following influences need to be considered if the torsional stiffness is required for other operating modes: Temperature Higher temperature reduces the dynamic torsional stiffness. Temperature factor St C Tdyn has to be taken into consideration in the calculation. Frequency of vibration Higher frequencies increase the torsional stiffness. By experience the dynamic torsional stiffness is 30% higher than the static stiffness. CENTA keeps record of exact parameters. Amplitude of vibratory torque Higher amplitudes reduce the torsional stiffness, therefore small amplitudes result in higher dynamic stiffness. CENTA keeps record of exact parameters. The relative damping is the relationship of the damping work to the elastic deformation during a cycle of vibration. The larger this value [ψ], the lower is the increase of the continuous vibratory torque within or close to resonance. The tolerance of the relative damping is ±0%, if not otherwise stated. The relative damping is reduced at higher temperatures. Temperature factor St Ψ has to be taken into consideration in the calculation. The vibration amplitude and frequency only have marginal effect on the relative damping. nmax nd The maximum speed of the coupling element, which may occur occasionally and for a short period (e.g. overspeed). The characteristics of mounted parts may require a reduction of the maximum speed (e.g. outer diameter or material of brake discs). The maximum permissible speed of highly flexible coupling elements is normally 90% thereof. Ka Ka max The continuous permissible axial displacement of the coupling. This is the sum of displacement by assembly as well as static and dynamic displacements during operation. The maximum axial displacement of the coupling, which may occur occasionally for a short period (e.g. extreme load). The concurrent occurrence of different kinds of displacements is handled in technical documents (displacement diagrams, data sheets, assembly instructions). CF-A-EN PAGE APP-3 PUBLISHED 0.

By experience the dynamic stiffness is higher than the static one. The factor depends on the coupling series. Kr Kr max The continuous permissible radial displacement of the coupling. This is the sum of displacement by assembly as well as static and dynamic displacements during operation. The continuous permissible radial displacement depends on the operation speed and may require adjustment (see diagrams Sn of the coupling series). The maximum radial displacement of the coupling, which may occur occasionally and for a short period without consideration of the operation speed (e.g. extreme overload). The concurrent occurrence of different kinds of displacements is handled in technical documents (displacement diagrams, data sheets, assembly instructions). Cr Crdyn The radial stiffness determines the radial reaction force on the input and output sides upon radial displacement. By experience the dynamic stiffness is higher than the static one. The factor depends on the coupling series. Kw Kw max The continuous permissible angular displacement of the coupling.

As a component supplier CENTA is not responsible for such calculations, and cannot accept any liability for gear noise/-damage or coupling damage caused by torsional vibrations. CENTA recommends that a torsional vibration analysis (TVA) is carried out on the complete drive train prior to start up of the machinery. In general torsional vibration analysis can be undertaken by engine manufacturers, consultants or classicfication societies. CENTA can assist with such calculations using broad experience in coupling applications and torsional vibration analysis. 5.
