This paper presents the analysis of failure causes and reliability
assessment executed for the gearbox of the bucket-wheel excavator SRs
470.20/3 “TAKRAF” (produced by “Lauhhammer”, Germany), which is
engaged in overburden excavation at the surface mine ’Kostolac’ (in
Serbia). In order to determine during which phase the error was made
(during the design process, production or exploitation), failure analyses
and assessments of reliability have been performed for gearbox elements
through the use of Pareto analysis, FTA - Fault Tree Analysis, reliability
allocation and failure intensity. For the calculation of reliability allocation
and failure intensity an adequate program package was developed.
Through the use of the above mentioned procedures data necessary for the
identification of most important elements for the analysis regarding the
maintenance process and failure prevention measures have been collected.
