1 BoWex FLE-PA DBGM BoWex-ELASTIC DBP Flange coupling for I. C.-engines BoWex BoWex-FLE-PA BoWex ELASTIC BoWex FLE-PA couplings are torsionally rigid curved-tooth flange couplings, made from a combination of nylon and steel, for diesel engine s in combination with hydraulic pumps. The FLE-PA mounting flange is made from glass fiber reinforced polyamide with high mechanical stability and thermal strength. The coupling hub with external curved teeth is made from steel. The BoWex FLE-PA allows an extremely short installation space. Apart from that it is easy to assemble without any additional tools for alignment. BoWex-ELASTIC is highly flexible, combining the benefits of the wellapproved BoWex system with the suppleness of a highly flexible coupling in compact design. Torsional vibrations and shock loads that may occur are dampened and reduced. The BoWex-ELASTIC consists of a highly flexible, annular rubber element from temperature-resistant natural caoutchouc, stressed for torque-tobore ratio, and a BoWex coupling hub to be plugged-in axially

2 BoWex FLE-PA couplings Flange coupling for I.C.-engines Types FLE-PA No. 016 and BoWex-ELASTIC No.055 High standards in quality and design are the basis for all KTR products. KTR couplings for I. C.-engines are subject to particularly strict criteria for the right balancing of vibrations in a system. The selection of couplings in combination with I.C.- engines requires a certain basic knowledge and some experience. Thus, the selection of the wrong coupling may cause torsional vibrations in the system which would result in an early failure of the coupling and other components. EDP calculation programs for the coupling selection allow us to assure our customers of a safe and long-term operation of the couplings. The team of KTR design engineers is available for our customers to solve special problems. Many users of KTR couplings all over the world benefit from this know-how. Advice seeking to solve problems and support will characterize our efficiency in the future, too. In the range of I. C.-engines we distinguish between two coupling systems which are necessary for an optimum and safe adaptation to the market conditions for s: The torsionally stiff BoWex FLE-PA flange coupling for the use in mobile hydraulics for a direct of hydraulic pumps. The highly flexible BoWex-ELASTIC HE coupling for s subject to dangerous torsional vibrations.

11 BoWex - ELASTIC Highly flexible couplings Coupling selection 1. BoWex-ELASTIC couplings should be selected in accordance with DIN 740 part 2. The coupling must be sufficiently sized to ensure that the maximum permissible coupling load is not exceeded in any operating condition. It is therefore necessary to compare the actual loads with the permissible rated parameters of the coupling according to tables listed below. For s subject to dangerous torsional vibrations it is necessary for a safe operation to review the by means of a torsional vibration calculation. 1.1 Load by rated torque The permissible rated torque TKN of the coupling must, at all operating temperatures, be at least as high as the rated torque T N of the machine. 1.2 Load by torque shocks The maximum permissible torque of the coupling must, at all operating temperatures, be as high as the operational peak torque T S, taking into account the shock factor S Z. T K max T S S z S t Shock on driving side T S = T AS M A S A Shock on n side T S = T LS M L S L J L J A M A = M L = J A + J L J A + J L With knowledge of mass distribution, direction and type of shock it is possible to calculate the peak torque T S. If the moments of inertia are unknown, M A or M L = 1. T KN T N S t 1.3 Passing through resonance range The peak torque TS arising when the T K max T S S Z S t resonance range is passed through T N [Nm] = 9550 must not exceed the maximum P AN/LN [kw] torque T kmax of the coupling, taking n [1/min] into account the temperature. 1.4 Load by vibratory torque shocks The permissible vibratory torque T KW of the coupling, at the operating speed and ambient temperature, must not be exceeded by the biggest periodical vibratory torque T W. With operating frequencies f > 10 Hz the heat produced by damping in the elastomer is considered as damping power P W. T KW T W S t P KW P W The permissible damping power P KW of the coupling depends on the ambient temperature and must not be exceeded by the actual damping power produced.

-engines Additional Information Use of PC with special software for coupling selection Application: 3-cylinder diesel engine - screw compressor Use: BoWex-ELASTIC 42 HE - 50 Shore A Calculation:

This ensures a resonancefree operation of the machine, along with a safe, long-lasting operation of the components. This is part of the usual KTR standard service.

13 BoWex Curved-tooth gear couplings Flange couplings for I.C.-engines Additional Information Use of PC with special software for coupling selection Application: 3-cylinder diesel engine - screw compressor Use: BoWex-ELASTIC 42 HE - 50 Shore A Calculation: Acceleration from 300 min -1 to 2700 min -1 KTR makes use of special simulation calculation programs for the coupling selection and the torsional vibration determination of the system. This ensures a resonancefree operation of the machine, along with a safe, long-lasting operation of the components. This is part of the usual KTR standard service. BoWex BoWex-FLE-PA BoWex ELASTIC Use of CAD and FEM systems for development and construction Apart from new products the team of KTR design engineers develops specific solutions for customers which are adapted to your application in detail. For that purpose we make use of latest 3D-CAD and FEM equipment, ensuring an optimum and quick service. R & D center Test benches KTR has test benches in its research and development center with servo-hydraulic and electronic control and data processing by PC. A special software which was developed for KTR ensures a short-term and detailed evaluation. In total ten static and dynamic test benches of different performance are installed in the R & D center. These test benches are used to test performance, capacity of resistance to wear, etc. of KTR elements. Apart from that serial tests are performed to ensure a constant quality standard of KTR products. 93
