2 mart Drive olutions Flexible Hadeflex -couplings The flexible DECH Hadeflex couplings are claw couplings with flexible elements to provide a torsionally flexible connection for shafts. The flexible elements excel in their wear resistance, their oil, ozone and ageing resistance and their temperature resistance from -20 C to +80 C. Thanks to their flexiblility, impacts, rotary vibrations and noises are effectively absorbed. The flexible elements are dimensioned such that radial, axial and angular movements between the two halves of the coupling are cancelled out. The flexible DECH Hadeflex couplings are of the plug-in type for installation and do not involve any particularly rigorous requirements with respect to alignment accuracy. The balancing quality is, in accordance with DIN-IO 1940, in the quality range 16. DECH Hadeflex couplings can be used in the whole of machine construction wherever a reliable shaft connection is needed between motor and machine. Type X The DECH Hadeflex version X coupling is failsafe up to the fracture moment of the cast iron transmission cam and this provides maximum operational safety. The coupling star can be supplied with hardness 92 hore A and 98 hore A. With the fixed position of the coupling star its deformability in axial direction is free, and so no damaging axial forces can act on the machine bearing even with alternating torque. Type TX with taper bush The DECH Hadeflex version TX coupling combines the outstanding features of the flexible couplings with the advantages of the taper bush system: fast and easy installation for a torsionally flexible connection between shafts and elimination of shaft balancing errors. The TX version with taper bush has the advantage that even with greater shaft tolerances there is a backlashfree and at the same time axial fixing of the shaft. In addition the close sliding fit makes axial alignment of the coupling easier. The coupling star can be replaced by a simple axial displacement of the coupling halves without having to disassemble the machines connected Type > tandard coupling FW/FNW > tandard coupling XW > Taper-bush type TX Type F The Hadeflex version F coupling is manufactured in two-piece and three-piece variants. With the two-piece coupling (FW series) it is possible to install packages after axial displacement of the drive engines or machines. With the threepiece coupling (FNW series ) it is possible to install packages without axial displacement of the drive engine or machine. 2
