Cardan Shafts for Industrial Applications - Dana

Selection of Spicer ® GWB TM cardan shaftsTypical types of torques:TPulsating stressT < T DSchThe maximum peak torque T SP is the extremelyrarely occuring torque of the system (crash,emergency case).This maximum torque (T SP ) should not exceedthe functional limited torque T CS of the cardanshaft.Alternating stressT SP < T CSTT < T DWT SP = Maximum peak torqueT N = Nominal torqueT CS = Functional limit torque ofthe cardan shaft[Nm][Nm][Nm](see data sheets)Light shock load: K = 1,1 – 1,5Heavy shock load: K = 2 – 3Driven machinesDriven machinesCentrifugal pumpsMixersGenerators (continuous load)Bucket wheel reclaimersConveyors (continuous load)Bending machinesSmall ventilatorsPressesMachine toolsRotary drilling rigsPrinting machinesLocomotive secondary drivesContinuous castersMedium shock load: K = 1,5 – 2Crane drivesDriven machinesCentrifugal pumpsGenerators (non-continuous load)Extra-heavy shock load: K = 3 – 5Driven machinesConveyors (non-continuous load)Continuous working roller tablesMedium ventilatorsMedium section millsWood handling machinesContinuous slabbing andSmall paper and textile machinesblooming millsPumps (multi-cylinder)Continuous heavy tube millsCompressors (multi-cylinder)Reversing working roller tablesRoad and bar millsVibration conveyorsService factor KLocomotive primary drivesScale breakersStraightening machinesHeavy shock load: K = 2 – 3Cold rolling millsThe service factors shown inthe following tables should beused as approximate valuesonly.Driven machinesLarge ventilatorsMarine transmissionsCalender drivesTransport roller tablesReeling drivesBlooming standsExtreme shock load: K = 5 – 10Driven machinesSmall pinch rollsFeed roller drivesSmall tube millsWrapper roll drivesHeavy paper and textile machinesPlate-shearsCompressors (single-cylinder)Reversing slabbing50Pumps (single-cylinder)and blooming mills
