6 Basics Introduction The rotationally resilient coupling of the TSCHAN Nor-Mex series is flexible in all directions and therefore compensates for angular, parallel and axial shaft misalignments of the connected machines. Misalignments can be caused, for example, by inaccurate assembly, heat movements or settling phenomena. Avoiding torsional vibration By virtue of the rotational resilience of the coupling, dangerous torsional vibrations from the operational range of plant machinery can be transfer to rotational speed ranges in which no negative effects are to be expected. The elastic intermediate rings possess a high material damping capability which makes it possible for the couplings to keep the resonance enhancements within limits when passing through dangerous speed ranges, thereby protecting the coupled machines against damage. The couplings also mitigate torque shocks and cause a vibrating system that has been excited by an impact to come to rest very quickly due to the material damping qualities. The conduction of structure-borne noise is prevented. lastomer materials Synthetic rubbers are used as base material for the elastic elements of the Nor-Mex couplings. As a rule these are electrically conductive and therefore prevent undesirable static charges. For the elastic elements of the TSCHAN Nor-Mex coupling series, there are two different material hardnesses available as standard. 1. Perbunan (Pb 7 with nitrile rubber (NBR) as the basic material and a hardness of 72 Shore A. 2. Perbunan (Pb 8 with nitrile rubber (NBR) as the basic material and a hardness of 82 Shore A. The resilience of the individual elastomer materials is designated by their shore hardness. From these values an indirect conclusion can be drawn with respect to the torques the coupling is able to transmit and its spring stiffness. For further details, please see the technical data sheet. nvironmental conditions The employed elastomer materials operate reliably in ambient temperature ranges of 30 C to +100 C. Please contact RINGFDR POWR TRANSMISSION if higher ambient temperatures are involved. The influence of the temperature on the coupling size selection is explained in more detail in the below-mentioned design directives. It is only allowed to operate the coupling in normal industrial air. Aggressive media may attack the coupling components, bolts and elastic elements and therefore present a danger to the operational safety of the coupling. The coupling can be certified in accordance with the uropean Directive 94/9/ C, also known as ATX95. Please contact RINGFDR POWR TRANSMISSION regarding the declaration of conformity according to 94/9/C and the effects of aggressive ambient media.

7 Basics Dimensioning of coupling - design directives The dimensioning of the elastic TSCHAN couplings is based on the nominal torque T N and maximum impact torque T max of the machines. T N = Nominal torque of machine [Nm] P N = Machine power [kw] n N = Operating speed [min -1 ] T N = 9550 P N / n N (1) The following equation applies when subjected to the nominal torque: T KN > T N S S f ( T KN = Nominal torque of coupling [Nm] acc. to catalogue data T N = Nominal torque of machine [Nm] acc. to equation (1) S = Temperature factor [-] according to table S f = Service factor [-] S A S S A = oad factor of drive side S = oad factor of output side Verifying the maximum torque of the coupling: The following equation applies for transient impact torques, which occur e.g. by starting an electric motor. T Kmax > T max S S Z ( T Kmax = Maximum torque of the coupling [Nm] according to catalogue T max = Maximum impact torque of machine [Nm] (e.g. when starting an electric motor: T max = T Kipp T Kipp = Tipping torque by starting with directly engaged asynchronous motor e.g. T Kipp ~ 2,5 T; observe details of motor producer) Start-ups per hour [1/h] Start-up factor S Z < ,3 >240 On request S Z = Start-up factor Check the power transmission capability of the shaft-hubconnection. The nominal torques stated in the tables will be reliably transmitted by the couplings. The introduction of the torque into the coupling hub has to be verified by the user of the coupling according to recognized rules of technology. If necessary, the second key is to be offset by 180. Observe the maximum permissible speed of the coupling. Check whether balancing is necessary. We advise to balance the coupling parts or sub assemblies if the circum ferential speed at the outer diameter exceeds 22 m/s. Balancing can only be performed on couplings with finish-bores. Unless otherwise specified, the half-key convention applies, so that the coupling hubs are balanced prior to producing the keyways. Required are balancing quality and balancing speed. Dimensioning example xample for dimensioning a coupling for a pump drive with electric motor type IC 225 M; preselected type: TSCHAN Nor-Mex G Input power P N = 45 kw Operating speed n N = 1480 min -1 Nominal torque TN = 9550 P N / n = / 1480 = 290 Nm Ambient temperatur = 65 C Acc. to equation (1) Temperature factor S = 1,2 Pb72 oad factor Drive motor oad factor of drive side S A = Working machine oad factor of output side S = Directly engaged asynchronous motor ( -connection) 1 Centrifugal pump - torque characteristics uniform with little variations, skight shocks Required nominal torque of the coupling T KN > T N S S f = 290 Nm 1,2 1,25 = 435 Nm S Z = Start-up factor 1,25 Figure b) Acc. to equation ( Check selected coupling size Check whether the hub bore is able to accommodate the shaft diameters. The values of the maximum finish bores stated in the tables are applicable for keyed connections according to DIN 6885/1 and must not be exceeded. The dimension of coupling G 168 Pb72 is OK for the performance data and a nominal torque of 630 Nm is selected. The operating speed of 1480 min -1 results in a circumferential speed of 13 m/s. Therefore it is not necessary to balance the coupling parts. If the shaft-hub connections are dimensioned sufficiently, this coupling can be used. 7

8 Basics Technical installation instructions Arrangement of the coupling parts The coupling hubs have to be arranged on the shaft ends in accordance with the coupling type. In order to obtain a shaft-hub connection that is capable of carrying the load it is important to ensure that the hubs are pushed onto the shaft until the face of the hub is flush with the shaft end. Finished bore The stated values for the finished bore d 1f max /d 2f max are valid for a keyway according to DIN 6885/1 and must not be exceeded. To ensure true running, select the bore fit in such a manner that, when mating it with the shaft tolerance, a tight fit or light interference fit, such as e.g. H7/m6 or tighter, results. Fastening on a shaft If not specified TSCHAN couplings are usually supplied with keyways according to DIN 6885/1. In addition, the hub should be axially locked in position, for example by means of a set screw, or by means of distance rings in case of longer shaft ends. The key must be axially fixed in the shaft. Observe restoring forces The coupling compensates the permissible misalignments with low restoring forces. Please observe the alignment values specified in the assembly and operation manual. If highly loaded bearings are involved, the additional loads resulting from the restoring forces should be taken into consideration. In such cases, please contact RINGFDR POWR TRANSMISSION for more detailed information. Shaft end bearings The shaft ends to be coupled should be supported by bearings which are directly fitted in front and after the coupling. Attention! In the interest of further development, we reserve the right to make changes which serve technological progress. Carefully observe the actually instructions given in the relevant installation and operation manual, which can be downloaded from our webpage Data overview: The technical data tables for the coupling types supplied in this catalogue include elastic elements that are available in two different shore hardness values (Pb72 and Pb8. The higher the hardness of the elastic elements, the higher the torque transmission capability of the coupling and as a result the higher is the spring stiffness. The rated torque T KN listed in the tables is the torque that the coupling is capable of transmitting continuously. The maximum torque T Kmax is the torque that the coupling is able to transmit for short periods, e.g. during start-up. When the hard elastic element of Pb82 is used for multi-part coupling designs, it has to be taken into account that the maximum transmittable torque (T KGmax ) is reduced. In these cases, T Kmax is limited by the frictional engagement between the coupling hub and the claw ring. Torsional vibration analyses (DSR) are performed by specialists to optimize the drive line. To this purpose, a detailed description of the oscillatory system is required, including the mechanical arrangement (spring-mass system) as well as the plant-related excitation functions. The specific coupling data such as stiffness, damping and mass moments of inertia will be supplied on request.

9 Basics Principle of the one-part design lastic elements replacement requires extensive dismounting operations as the driving and driven machines have to be moved axially. Principle of the multi-part design lastic elements replacement only requires a minimum of work and the driving and driven machines do not need to be axially displaced. 9
