Robust joints with high strength reserves

Easy to mount and dismount. RINGFEDER POWER TRANSMISSION products reliably transmit torques of up to 2.440 kNm and do not need wear-and-tear parts.

The new flange couplings made by RINGFEDER POWER TRANSMISSION GMBH are designed as a mechanic press fit. As with all tapered fits, it is easy to mount and dismount them using a standard tool. Additional components such as keyways or wedges are not required. Neither is it necessary to heat up the outer components or to cool down the inner ones to assemble them. If heat-shrunk flange couplings are used, they can get fastened prematurely in the assembly process; but even that challenge was no match for the ingenious Groß-Umstadt engineers. To dismount couplings, only the shrink disc needs to be loosened. Using oil pressure (i.e. a pump) and hence the conventional, rather problematic and environmentally-challenging process is a thing of the past.

Under the RINGFEDER trademark, RINGFEDER POWER TRANSMISSION GMBH - which is internationally known for its technically advanced solutions - offers flange couplings, designed for torques of 6.98 kNm up to 2,440 kNm at shaft diameters of 70 mm to 540 mm. The couplings do not just transmit the torque but also bending moments. Thus, their design lends itself to plant engineering and to the manufacturing of gear systems. In addition, it is an excellent choice for even the most difficult conditions, for example in mining applications. The flange couplings are simply pushed onto the shaft. By tightening the screws using a shrink disc, the fit is frictionally engaged and guarantees high strength reserves as well as high concentricity.

RINGFEDER POWER TRANSMISSION GMBH offers its customers a comprehensive and ever-growing range of products with its RING-flex steel disc couplings, GWS heavy-duty safety couplings, and the newly added TSCHAN coupling range - always endeavouring to be a One-Stop-Partner in coupling technology. Fields of application range from treatment plants to crushing units. RINGFEDER couplings can be used both on the drive end of large plants to connect them to the engine as well as on the output end. Conveyor systems, chemical plants, ship engines, crane drives, cable drums, mixers, presses, steel-works, power plants, steel-mills as well as in heavy equipment and plant engineering are examples of where they are being used successfully.
