2 2 FLEXIBLE COUPLIN The flexible Hadeflex couplings are claw couplings with a flexible element 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 flexibility, 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 Hadeflex couplings are of the plug-in type for installation and do not involve any particularly rigorous requirements with respect to alignment accuracy. Hadeflex couplings can be used in the whole of machine construction wherever a reliable shaft connection is needed between motor and working machine. TYPE X The Hadeflex version X coupling is fail-safe 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 BUH The 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 type with taper bush has the advantage that even with greater shaft tolerances there is a backlash-free 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 F The Hadeflex version F coupling is manufactured in two-piece and threepiece variants. With the two-piece coupling (FW series) it is possible to install packages after axial displacement of the drive engines or working machines. With the three-piece coupling (FNW series) it is possible to install packages without axial displacement of the drive engine or working machine.
