These torsional highly elastic CENTAMAX couplings were first introduced in 1980. Since that time they have been proved in numerous difficult applications.
Drives subject to torsional vibration especially diesel engine drives, where the driven components have relatively small inertias and are required to run over a wide speed range from low idling rpm to full engine speed, free from dangerous resonances. For these applications it is desirable to shift the critical speeds far enough below engine idling speed so that the whole engine working speed range can be utilized without limitation.
For such drives a torsionally very soft coupling is more desirable than a torsionally stiff coupling because the whole drive power train is then subjected to very low vibratory torques and is therefore more lowly stressed.
Important Areas of Application:
- Splitter gears, with several hydraulic pumps
- Compressors
- Ship propulsion
- Generator sets
- Pumping sets
- Locomotives
Design Sizes
The complete range is now comprised of 15 sizes for the torque range from 100 48000 Nm. This means it ranges from 1cylinder engines with a few kW up to large multi cylinder engines with about 3000 kW capacity. Types 4000 SD and 18000 SD (D means double) are comprised of 2 parallel acting elements, in order to increase the torque.
Materials
Inner Hub: Steel with minimum tensile strength of 600 N/mm2 (8500 psi).
Outer ring: High grade cast aluminium alloy.
Flexible disc: High quality, natural rubber (NR) in diffe rent Shore hardnesses, temperature resis tant.
For applications with high ambient temperature, especially in bell housings, we recommend the high temperature resistant version with Silicon elastomer (SI).
Allowable ambient temperature:
NR: –45°C up to + 90°C
SI: –45°C up to +120°C
