Design methods for drivetrain components are usually based on standardized guidelines or historically collected data. This also applies to synchronous belt drives such as timing belts, whose modern applications are characterized by increasing precision and performance. At the same time, their service life is directly influenced by numerous factors such as pretension, torque or ambient temperatures, or disturbed by variances in the tooth geometries. If there is a lack of specific understanding of the system, unplanned system failures or systematic over-dimensioning will result. In the presented reliability modeling project, this problem is addressed using the example of a passenger car steering gear. Using design of experiments for non-normally distributed lifetime data (L-DoE) and variable factor levels, relevant influencing factors are identified, their system effects quantified and transferred to an application-specific lifetime model.
