Material Carbon Steel, UsageApplication DG Set Double Diaphragm Couplings, Size 34 inch

Unique double diaphragm couplings use highly flexible diaphragms. These consist of rubber reinforced with nylon chords. Further at internal and external bolting pcd steel ring reinforcements are used. Torque ratings are determined after extensive tests and have large service factor against rupture. Rupture torque is typically 6 as much as ten times rated torque. At nominal torque torsional angle is large, Typically 10 to 15 degrees. Torsional stiffness is low. This yields low critical speeds, Usually below operating speed. Further torsional stiffness varies with load. At lower loads stiffness is lower. The feature allows operation at diverse selection of speeds. Favourable damping characteristics ensure vibration amplitude are limited at resonance. Design series, Series 1000, Series 1100 are for direct flywheel mounting. Series 1750 are for shaft to shaft connection. Series ip are perfect for diesel drives in association with cardan shaft, Highly popular for diesel driven vertical turbine fire pumps. Selection first selection is based on nominal torque, Max bore, Max speed, End fitment. Next for diesel / compressor drives in particular, Tv analysis is performed to check that vibratory torques are within acceptable limits in operating speed range. If necessary several sizes are tested, To obtain best match unique would be glad to perform tv analysis on request. For this normally we would require mass elastic data, Torque, Crank angle data for compressors note many alternative custom made designs can be offered to suit specific requirements. Torsional stiffness may vary,, A fifth of catalogue figures. Key features highly flexible and resilient low dynamic torsional stiffness torsional stiffness varies with load isolates and dampens torsional vibration ideally suitable for diesel engine drives, Compressors, Rolling mills, Dg sets pumps available for reputed makes of diesel engines & compressors.
