2 Description of coupling ROTEX - couplings are characterized by small dimensions, low weight and low mass moments of inertia yet transmit high torques. Running quality and service life of the coupling are improved by accurate all-over machining. Their application is ideal for transmitting torque while damping torsional vibrations and absorbing shocks produced by the uneven operation of certain prime movers. General description ROTEX - couplings are torsionally flexible and designed for positive torque transmission. They are fail-safe. Operational vibrations and shocks are efficiently dampened and reduced. The two congruent coupling halves with concave claws on the inside are periphally offset in relation to one another by half a pitch. In addition, they are designed in such a way as to enable an involute spider to be located between them. The teeth of the spider are crowned to avoid edge pressure if the shafts are misaligned. ROTEX couplings are capable of compensating for axial, radial and angular displacements of the shafts to be connected. torsion load on spider pressure Druck Performance In contrast to other flexible couplings, the intermediate members of which are subject to bending stress and are therefore prone to earlier wear, the flexible teeth of ROTEX couplings are subject to pressure only. This gives the additional advantage of the individual teeth being able to accept considerably higher loads.the elastomer parts show deformation with load and excessive speeds. Sufficient space for expansion should be ensured (see drawing deformation with load). The maximum torsion angle with ROTEX couplings of any size amounts to 5. They can be fitted both horizontally and vertically. deformation with load torsion requested mounting space min. D H x 0,05 Explosion-proof use ROTEX couplings are excellently suitable for power transmission in s in hazardous areas. The couplings are certified according to EC Standard 94/9/EC (ATEX 95) as units of category 2G and thus suitable for the use in hazardous areas of zone 1 and 2. Please read our information in the respective Type Examination Certificate and the operating and mounting instructions under Spiders An operating temperature range of - 40 to + C ensures perfect operation. Transient temperature peaks up to + 0 C do not cause any damage on the coupling. Continuous improvement of materials has resulted in a standard spider of 92 Shore A which offers various advantages over usual polyurethane materials. For higher torques it is also possible to make use of a spider 95/9 Shore A or 4 Shore D-F. The spiders are extremely resistant to wear, oil, ozone and ageing. In addition, they are resistant to hydrolysis (ideal for tropical climates). The high internal damping protects the against dynamic overload. standard spider tooth flanks crowned GS spiders tooth flanks rectangular, with web 1

4 Coupling selection The ROTEX coupling is selected in accordance with DIN 740 part 2. The coupling has to be dimensioned in a way that the permissible coupling load is not exceeded in any operating condition. For this purpose the actual loads have to be compared to the permissible parameters of the coupling. 1 Drives without periodical torsional vibrations e. g. centrifugal pumps, fans, screw compressors, etc. The coupling is selected taking into account the rated torques T KN and maximum torque T K max. 1.1 Load produced by rated torque Taking into consideration the ambient temperature, the permissible rated torque T KN of the coupling has to correspond at least to the rated torque T N of the machine. 1.2 Load produced by torque shocks The permissible maximum torque of the coupling has to correspond at least to the total of peak torque T S and the rated torque T N of the machine, taking into account the shock frequency Z and the ambient temperature. T KN T N S t P AN/LN [kw] T N [Nm] = n [1/min] T K max T S S z S t + T N S t Drive-sided shock T S = T AS M A S A Load-sided shock T S = T LS M L S L J L J A MA = M L = J A + J L J A + J L This applies in case if the rated torque T N of the machine is at the same time subject to shocks. Knowing the mass distribution, shock direction and shock mode, the peak torque T S can be calculated. For s with A. C.-motors with high masses on the load side we would recommend to calculate the peak driving torque with the help of our simulation programme. 2. Drives with periodical torsional vibrations. For s subject to high torsional vibrations, e. g. diesel engines, piston compressors, piston pumps, generators, etc., it is necessary to perform a torsional vibration calculation to ensure a safe operation. If requested, we perform the torsional vibration calculation and the coupling selection in our company. For necessary details please see KTR standard Load produced by T KN T N S t rated torque Taking into account the ambient temperature, the permissible rated torque T KN of the coupling has to correspond at least to the rated torque T N of the machine. 2.2 Passing through the resonance range T K max T S S t Taking into account the temperature, the peak torque T S arising when the resonance range is run through must not exceed the maximum torque T Kmax of the coupling. 2. Load produced by vibratory torque shocks T KW T W S t Taking into account the ambient temperature, the permissible vibratory torque T KW of the coupling must not be exceeded by the highest periodical vibratory torque T W P KW P W with operating speed. For higher operating frequencies f >, the heat produced by damping in the elastomer part is considered as damping power P W. The permissible damping power P KW of the coupling depends on the ambient temperature and must not be exceeded by the damping power produced.

23 Hub designs ROTEX -NORM Pin & bush coupl. Due to the numerous applications of ROTEX for many different mounting situations, this coupling system is available with various hub designs. These designs mainly differ in that they offer either positive or frictionally engaged connections, but mounting situations like, for example, gear shafts with integrated transmission cams or similar applications are covered, too. Design 1.0 hub with keyway and fixing screw Positive power transmission; permissible torque depends on the permissible surface pressure. Not suitable for backlash-free power transmission for heavily reversing operation. Design 1.1 hub without feather key, with setscrew Positive torque transmission for connections pressed or glued in. (No ATEX release) Design 1. hub with spline bore (page ) Design 2.0 clamping hub, single slotted, without keyway Frictionally engaged, backlash-free shaft-hub-connection. Transmittable torques depend on the bore diameter. (Only for ATEX category ) Design 2.1 clamping hub, single slotted, with keyway Positive power transmission with additional frictional tightness. The frictional tightness avoids or reduces reversal backlash. Surface pressure of the keyway connection is reduced. Design 2. clamping hub with spline bore (page ) Design 4.0 with CLAMPEX clamping set KTR 250 Frictionally engaged, backlash-free shaft-hub-connection for transmission of average torques. Design 5.0 w. CLAMPEX clamping set KTR 200/KTR 400 Frictionally engaged, backlash-free shaft-hub-connection for transmission of larger torques. Largest clamping set possible depends on the hub collar diameter. Clamping set screw fitting possible both internally and externally. For details of calculation please see CLAMPEX catalogue. Design.0 clamping ring hub (see ROTEX GS series) Integrated frictionally engaged shaft-hub-connection for transmission of higher torques. Screw fitting on elastomer side. For details about torques and dimensions see ROTEX GS catalogue on page 4. Suitable for high speeds. Design.5 clamping ring hub Design equal to.0, but clamping screws to be fitted externally. Suitable, for example, for disassembly of radial spacer tubes (special design). Special hubs on request Special lengthened hub/shaft with integrated cams. Special hubs on request Special hub with external taper as a frictionally engaged connection. 9

For different operating conditions please order our data sheet KTR-N 200 regarding displacements for ROTEX. The displacement figures may only be used one by one - if they appear simultaneously, they must be limited in proportion. Care should be taken to maintain the distance dimension E accurately in order to allow for axial clearance of the coupling while in operation. In case of an axial shifting the dimension "L" has to be considered as a minimum dimension in order to keep the spider free from pressure on its faces.
