Overview

A large number of failures in mechanical engineering is due to damage to 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 Parts 1 to 3 and is exclusively intended 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. The following modifications have been made with respect to DIN 743 Supplement 1:2000-10: a) clause 4.3 - Calculation of the safety of an axle with recess and relieve groove during bending in order to prevent fatigue failure and permanent deformation (example) has been replaced by clause 4.3 - Calculation of the safety of an axis with retaining ring groove during bending in order to prevent fatigue failure and permanent deformation (example). Previous editions: DIN 743 Supplement 1:2000-10.
