The FLEXDUR – HighSpeed (short form: FD-HS) All-metal couplings are developed and manufactured to the highest standards, especially for applications with higher speeds. The coupling uses bushed flexible disc packs of stainless spring steel as power transmitting elements. The special shape of the precision bushes results in a uniform tension distribution of the disc pack when assembled. The torque is transmitted backlash-free by means of high-strength fitting screws.
The disc pack is designed so that it combines high torque transmission capacity with suitability for high speeds; it has been specially designed for use in test benches. Nominal torques range from 320 Nm to 12 500 Nm. The permissible speeds are adapted to the requirements of the test specimens.
The FLEXDUR – HighSpeed has been designed with modular components. Therefore the coupling can be fitted to many different installation situations: As a torsionally rigid double-jointed coupling with two flexible disc packs it compensates for axial, radial and angular displacement and is therefore flexible in all directions.
Different mounting lengths are available as standard. For a completely backlash-free connection between shaft and hub, the FLEXDUR – HighSpeed is equipped as standard with clamping hubs as a shrink disc connection.
