A clutch that is both bi-directional and one-way might sound like a contradiction. But in fact, we offer just such a clutch. As a bi-directional clutch, the MTL can transmit torque from input to output shaft in either rotational direction. And, its one-way functionality prevents output shaft loads from backdriving into your other power transmission […]

Ringfeder on protecting buildings during earthquakes
1. Additional reinforcement of the building structure Earthquake-proof buildings generally consist of shear walls, cross braces, diaphragms, and moment-resisting frames. These components all serve to redistribute forces. For example, shear walls that are composed of several panels help buildings in motion keep their shape. Cross braces absorb compression and tensile forces by pushing back the […]
Ringfeder — Dynamical torsional stiffness: some couplings need finer tuning
The coupling is normally the softest element in the drive line, literally – but by no means the weakest link of the chain. Its configuration plays a decisive role in the functional capability of the driving and driven machine and in the reliability and lifetime of the entire drive system. The optimum adjustment of the […]

Locking assemblies optimize shredder performance for sustainable farming
Function principle Shredders are constructed with multiple blades that shred the residual crops. In principle, they have a motor that rotates the motor shaft which is fixed with a pulley, and the shaft with blades is fixed with a reducer pulley, with the result that the shaft speed is doubled. When the shaft rotates at […]
