5 Definitions and abbreviations 5.1 Lengths Universal joint shaft with length compensation Universal joint shaft without length compensation lB : Operating length (Please indicate with order.) lB : Operating length, corresponds to the universal joint shaft length l (Please indicate with order.) lz : Shortest length of the universal joint shaft (fully collapsed) lv : Available length compensation The distance between the driving and the driven machines, together with any length changes during operation, deter mines the operating length: Optimal operating length: Maximum permissible operating length:...

Components MDW Reversing fatigue torque rating. The shaft will have an infinite fatigue life up to this torque level. MDS Pulsating one-way fatigue torque rating. The shaft will have an infinite fatigue life up to this torque level. Where: MDS « 1.5 • MDW MK Maximum permissible torque. If this level is exceeded, plastic deformation may occur. Values available on request. Bearing Mz Permissible torque for rarely occurring peak loads. Bearing races may suffer plastic deformation at torque levels in excess of Mz. This can lead to a reduced bearing life. CR Load rating for bearings - when used with...
