Service FactorsTsubaki offers simplex, duplex and triplex chains in RF06B toRS40B of BS/DIN European standard. In ANSI standard, up to6 strands are available as standard items from RS40 to RS240and up to triplex for RS25 and RS35. In multiple strand chaindrives, the load is unequal across the width of the chain, so thetransmission capability of multiple strand chain is calculatedusing multiple strand factors shown in the table below.Table 1 : Multi-strand factorNo. of strands2 strands3 strands4 strands5 strands6 strandsService factor K sThe chain’s transmission capacity is affected if there is frequentload fluctuation. The appropriate service factor K s must beapplied based on the source of power and type of machine asshown in the table below. Please note that the service factor isnever smaller than 1.0.Table 2 : Service factor KsType ofImpactSmoothSome impactLarge impactMulti-strand factor1.72.53.33.94.6MachinesBelt Conveyors with smallload fluctuation, chainconveyors, centrifugalblowers, ordinary textilemachines, ordinary machineswith small load fluctuation.Centrifugal compressors,marine engines, conveyorswith some load fluctuation,automatic furnaces, dryers,pulverizers, general machinetools, compressors, generalwork machines, generalpaper mills.Press, construction or miningmachines, vibration machines,oil well rigs rubber mixers,rolls, roll gangs, generalmachines with reverse orlarge impact loads.ElectricMotororTurbine1.01.31.5Source of PowerInternal Combustion EngineWith hydraulicdrive1.01.21.4Withouthydraulic drive1.21.41.7Speed factor K v and sprocket teeth factor K CTable 3 : Speed factor, K v and sprocket teeth factor K CKv·Kc1.41.31.21.11.033Speed factor K vShock factor KThis coefficient is determined by the rate of inertia between thepower source (eg. motor or engine) and the driven machinery(rate of I, GD 2 ) as well as the amount of backlash in thetransmission equipment.When rate of inertia R > 10, R = 10When rate of inertia R < 0.2, R = 0.2When I or GD 2 for either the motor/power source or drivenmachinery is unknown, use the value of R on table 4.Table 4 : Shock factor KShock factor3.02.52.01.51.00.80.60.5k 0.40.30.2Sprocket teeth factor K c49 66 82 98 115 131 164Chain speed (ft/min)10 15 20 25 30 35 40 50 60Small sprocket teeth0For backlash in transmission equipmentR=Motor shaft converted inertia of loadInertia of motorFor NO backlash in transmission equipment, etc.0.2 0.3 0.5 0.8 1 2 3 5 8 10Hoist work ConveyorMillHoistgang rollcrane travel and shuffleInertia ratio RflywheelImbalance load factor K uWhen carrying out shuttle traction and lifting with two chains, orfour chains for shuttle drive and lifting, the chain tension is notuniform.
