Ringfeder Power Transmission is the international leader in niche markets for drive and damping technology. Under the strong brand, Ringfeder® offers users worldwide outstanding shaft-hub connections, damping solutions and coupling systems for the highest functionality and durability requirements in a wide variety of industries.
Simple and quick assembly and disassembly, complete freedom from maintenance and wear, absolutely backlash-free power transmission: Ringfeder® Locking Assemblies are friction-locked shaft-hub connections manufactured to the highest quality standards. They are suitable for the precise fastening of all types of hubs, e.g. toothed gears, running wheels and chain sprockets, levers, cam discs, belt and brake discs, slip-on gears, couplings or flanges, on shafts and axles. Compared to external clamping connections, e.g. shrink discs, locking assemblies are installed between shaft and hub. By tightening the clamping screws, inner and outer rings press themselves onto the contact surfaces of the components to be connected, thus creating a friction-fit press connection. This allows not only the highest torques but also axial and radial as well as bending loads to be transmitted reliably. RINGFEDER® Locking Assemblies are the superior alternative to conventional shrink-fits, wedge, keyway or polygonal connections and offer outstanding concentricity and resistance to alternating torsion. Our locking assemblies are available to users in various standard designs and sizes as well as customised special solutions.
The high-quality original from the world market leader: Ringfeder® Shrink Discs are flange-shaped, friction-locked shaft-hub connections and the more powerful and reliable alternative to conventional shrink fits, wedge, keyway or polygonal connections. In contrast to internal locking devices, e.g. locking assemblies, the pressure is applied from the outside to the hollow shaft or hub, thus creating an absolutely backlash-free, frictionally engaged connection between shaft and hub. The shrink disc is therefore not in the load path – instead, the torque is transmitted in a force-locking manner at the joining surface between shaft and hub without an intermediate element. Ringfeder® Shrink Discs also convince through complete freedom from wear and maintenance, easy assembly and dismantling as well as outstanding resistance to alternating torsion and concentricity properties. Depending on customer-specific requirements, our shrink discs are available in proven standard and specially developed special variants, in two- and three-part designs as well as in stainless steel. In addition to torque and bending loads, axial and radial loads can also be transmitted.
