MSC
Innovative coupling designed to satisfy a vast spectrum of diesel drive and compressor applications.
The Standard Range Comprises
- Flywheel to shaft
- Shaft to shaft
- Flange to flange
- Flywheel to shaft ½ stiffness
- Shaft to shaft ½ stiffness
Spanish F100 frigate fitted with four Renold Hi-Tec MSC 12.5 half stiffness couplings between the Navantia MTU diesel engine and the alternator for power generation. Two Renold Hi-Tec DCB 848.0 cardan shaft couplings are fitted to the cruise diesel engines on the main propulsion drive.
Applications
- Marine propulsion
- High power generator sets
- Reciprocating compressors
Features
- Intrinsically fail safe
- Control of resonant torsional vibration
- Maintenance free
- Severe shock load protection
- Misalignment capability
- Zero backlash
- Noise attenuation
Benefits
- Ensuring continuous operation of the driveline in the unlikely event of rubber damage.
- Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
- Radial removal of rubber elements allows replacement without moving driven or driving machine.
- No lubrication or adjustment required resulting in low running costs.
- Avoiding failure of the driveline under short circuit and other transient conditions.
- Allows axial and radial misalignment between the driving and driven machines.
- Eliminating torque amplifications through pre-compression of the rubber elements.
- Giving quiet running conditions in sensitive applications by the elimination of metal to metal contact.
Construction details
- The driving member is manufactured in steel to BS3100 Grade BT2
- The inner member is manufactured in steel to BS3100 Grade A6
- The driving flange is manufactured in steel to BS3100 Grade A3
- Rubber elements can be fitted and removed without moving the driving or driven machine.
