Flexible Couplings ( DCB )

Fail safe coupling for use on reciprocating machinery upto 5520 kNm.
	The Standard Range comprises • Flywheel to shaft • Flywheel to flang • Shaft to shaft
	Applications • Marine propulsion • High power generator sets • Reciprocating compressors

Features	Benefits
• Intrinsically fail safe	• Ensuring continuous operation of the driveline in the unlikely event of rubber damage.
• Control of resonant torsional vibration	• Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
• Severe shock load protection	• Avoiding failure of the driveline under short circuit and other transient conditions.
• Maintenance free	• With no lubrication or adjustment required resulting in low running costs.
• Misalignment capability	• Allows axial and radial misalignment between the driving and driven machines.
• Zero backlash	• Eliminating torque amplifications through precompression of the rubber elements.
• Noise attenuation	• Giving quiet running conditions in sensitive applications by the elimination of metal to metal contact.

Construction details
	Each rubber element would be 5.5 inch diameter. Each cavity would house three rubber elements. Eight rubber element cavities radially spaced around scoupling diameter referred to as "Series 8" coupling
• Available options are : Series 6, Series 8, Series 10, Series 16
• 2,3,4 or 5 rubber elements per cavity are available. Rubber elements upto 15" diameter are manufactured.
• The inner and outer members are manufactured in stell to BS3100 Grade A1.
• Some sizes are available in SG Iron Castings to BS2789 Grade A1.
