DIN 743-1
Calculation of load capacity of shafts and axles - Part 1: General

Title (German)

Tragfähigkeitsberechnung von Wellen und Achsen - Teil 1: Grundlagen

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 standard contains the basic equations and the methodology for proof of load bearing capacity for shafts and axles. This standard 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 743:2000-10, clause 5: a) for static proof a distinction between the proof of avoidance of permanent deformation and the proof of the avoidance of precracks of hard surface layers has been made; b) determination of the crack boundary has been supplemented. Previous editions: DIN 743-1:1998-05, 2000-10.
