Cardan Shafts for Industrial Applications - Dana

Additional information and ordering instructionsSelection of cardan shaftsThe selection of a SPICER ® GWB TM cardan shaft ist determinednot only by the maximum permissible torque of the shaft and theconnections but also by a variety of other factors.For the exact determination andselection of cardan shafts, seethe Selection of Cardan Shaftspages in this brochure.Dana engineers can preciselycalculate the correct size of theshaft and joint for your applicationwith the use of computerprograms created specificallyfor this purpose.In order to best match your requirements,you’ll be asked toprovide the following information:• Installation length of thecardan shaft• Maximum joint anglerequirement• Required length compensation• Maximum rotation speed ofthe shaft• Shaft end connection details• Maximum torque to betransmitted• Nominal torque to betransmitted• Load occurrences• Description of the equipmentand working conditionsSpecific applicationsCardan shafts in railwaytransmissionsThe selection of cardan shafts inthe secondary system of railwayvehicles must be based on themaximum torque that can betransmitted to the track (wheelslip or adhesion torque).Cardan shafts in crane traveldrivesThe particular operating conditionsfor travel drives of craneshave been taken into considerationin the DIN-standard 15 450.As a result, cardan shafts forthese applications can be selectedby using that standard.Cardan shafts in marinetransmissionsThese cardan shafts are subjectto acceptance and must correspondto the standards of therespective classification society.Cardan shafts for other formsof passenger conveyanceCardan shafts used in amusementpark equipment, ski liftsor similar lift systems, elevators,and rail vehicles must be inaccordance with the standardsand specifications of the appropriatelicensing and supervisoryauthorities.Cardan shafts in explosiveenvironments (Atex-outline)For the use of cardan shafts inareas with danger of explosion,an EC-conformity certificate acc.to EC-outline 94/9/EG can beprovided. The possible categoriesfor the product „cardan shaft“ are:a) in general: II 3 GDc T6b) for cardan shafts with adaptedfeatures: II 2 GDc T6The cardan shaft should not beused under the following operatingconditions:• Within the critical bendingspeed range of the drive• Within the critical torsionalspeed range of the drive• At operating angles which exceedthe specified maximum(refer to drawing confirmedwith order)• At dynamic and static operatingtorques which exceed thespecified limit (refer to drawingconfirmed with order)• At speed x deflection angle(n x b) conditions whichexceed the limit (refer toSPICER ® GWB TM catalogue)• For usage time which exceedsthe calculated bearing lifetimeof the joint bearingsIf you’d like more information onSPICER ® GWB TM cardan shafts,or would like to discuss specificapplication requirements withan engineer, please call Danaat 00 49 (0) 201- 81 24 - 0 or visitwww.gwb-essen.de,www.dana.com.51
