One-part design with brake disk - Brake disk made of nodular graphite iron The TSCHAN ® TNM ETW is an torsionally flexible and shock-proof claw coupling with brake disc. They compensate for angular as well as radial and axial shaft misalignment within fixed tolerances. The torque is transmitted through an elastic transitional ring. The elastic transitional ring made of Perbunan (Pb) with nitrile rubber as the base material dampens shocks and torsional vibrations, is oil-proof, insensitive to temperature and normally electrically conductive. This prevents undesirable static charging, among other things. The coupling can be used for either direction of rotation and be installed in any position. TSCHAN ® TNM ETW One part design with brake disk in nodular cast iron. Elastic intermediate ring in different hardnesses: standard Pb72, hard Pb82. General features Torsionally flexible, compensate for angular, radial and axial shaft misalignment Intermediate rings loaded in...

RINGFEDER® Flange Couplings are the better alternative to press fits. Neither additional components such as keyways or wedges, nor a warming of the outer section and cooling of the inner section are required. The flange coupling is simply pushed onto the shaft and fastened so it is frictionally engaged by tightening the screws in the shrink disc. They transfer torque and bending moments as well as axial and radial forces. Advantages Strong connection with high torque capacity Easy assembly and disassembly Backlash-free shaft hub connection High level of true running accuracy Applications Mining companies Plant manufacturers Gearbox manufacturers Designs Version A Shrink Discs with hexagon head screws HM = Centering outside HF = Centering inside Version B Shrink Discs with hexagon socket head cap screws HM = Centering outside HF = Centering inside Explanations to tables Basic dimensions when screws are not tightened d w1 = Solid shaft diameter d w2 = Solid shaft diameter A =...

Shaft Couplings RfN 5071 Standard series – this range is the most popular, being used in most applications. Characteristics Shrink discs are the modern method for creating a mechanical shrink fit. The shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening locking screws the thrust rings are drawn together compressing the inner ring and applying pressure to the outside of the hub clamping it to the shaft. Being positioned around the hub there is only one interface transmitting the loads giving the shrink disc method distinct advantages such as offering the possibility of very concentric and well balanced connections that are suited to high speed applications. Traditional shrink fits require complicated calculations, close machining tolerances and fine surface finishes, they also need considerable effort with mounting and removal. The Shrink Disc connection has none of these disadvantages and is better than any of...
