DIN 743 Beiblatt 2
Calculation of load capacity of shafts and axles - Supplement 2: Examples to part 4
Tragfähigkeitsberechnung von Wellen und Achsen - Beiblatt 2: Anwendungsbeispiele zu Teil 4
A large number of failures in mechanical engineering is due to damage on axles and shafts. The most frequent cause for this is fatigue failure (fatigue fractures, vibration fractures). In addition to the optimum structural design, the calculation of the safety against the occurrence of fatigue failure and damage due to maximum load (permanent deformation, precrack) presents a necessary measure. This supplement contains application examples to Part 4 and is exclusively for demonstration of the calculation process. This supplement has been prepared by Working Committee NA 060-34-32 AA "Wellen und Welle-Nabe-Verbindungen" ("Shafts and shaft to collar connections") at the Technical Section Power transmission engineering of the Mechanical Engineering Standards Committee (NAM) at DIN, the German Institute for Standardization e. V. The DIN 743 standard series - Shafts and axles, calculation of load capacity - consists of - Part 1: General basics; - Part 2: Theoretical stress concentration factors and fatigue notch factors; - Part 3: Strength of material; - Part 4: Fatigue limit, endurance limit - Equivalently damaging continuous stress; - Supplement 1: Examples to Part 1 to 3; - Supplement 2: Examples to Part 4.
