Selection of Spicer ® GWB TM cardan shaftsThe design of cardan shaftsmust exclude all possible dangerto people and material bysecured calculation and testresults, as well as other suitablesteps (see Installation andMaintenance/Safety Instructions).The selection procedure describedon these pages is onlya general recommendation.Please consult Dana engineersfor the final design for yourapplication.The selection of a cardan shaftshould be based on the followingconditions:1. Specifications of cardanshafts2. Selection by bearing life3. Operational dependability4. Operating angles5. Speed6. Length dimensions7. Load on bearings of theconnected units1. Specifications of cardan shaftsT CS = Functional limittorque [Nm]Up to this maximum permissibletorque, a load may be appliedto a cardan shaft for a limitedfrequency without the workingcapability being affected bypermanent deformation of anycardan shaft functional area. Thisdoes not result in any unpermissibleeffect on bearing life.Yield torqueThis torque level leads to irreversibleplastic deformation of thecardan shaft which could resultin a failure of the complete drivesystem.T DW = Reversing fatiguetorque [Nm]At this torque, the cardan shaftis permanently solid at alternatingloads. The values for cardanshafts of series 687/688 with weldedbalancing plates are lower.With a fatigue torque of thisorder, the transmission capacityof the flange connection mustbe checked.T DSch = Pulsating fatiguetorque [Nm]At this torque, the cardan shaftis permanently solid at pulsatingloads.T DSch = 1,4 · T DWL C = Bearing capacity factorThe bearing capacity factor takesinto consideration the dynamicservice life C dyn (see DIN/ISO281) of the bearings and the jointgeometry R. The L C values for thedifferent shaft sizes are shown inthe tables (see data sheets).When selecting cardan shafts,the bearing life and the operatingstrength must be consideredseparately. Accordingto the load state, the reversingfatigue torque T DW or the pulsatingfatigue torque T DSchmust also be taken into consideration.48
Selection of Spicer ® GWB TM cardan shafts2. Selection by bearing lifeBy bearing capacity factor L CThe bearing life Lh of a cardanshaft depends on the bearingcapacity factor and is based onthe following formula:L h =L C · 10 10n · b · T 10/3 · K 1If the desired bearing life L h isgiven, the joint size can be calculatedby the bearing capacityfactor L C .L C =L h · n · b · T 10/3 · K 110 10The L C values can be taken fromthe tables (see data sheets).L C = Bearing capacity factorn = Operating speed [rpm]b = Operating deflectionangle [
