Апстракт:
Gears in planetary gear set operate with various stress levels and with various stress cycle’s numbers. Failure arises in the place where these conditions are the worst. This is the reason that failure ofone gear causes replacement of complete gear assembly, including gears utilized partly only. Elementary reliability oriented to every potential failure in planetary gear set can indicate it and direct to look for solution. The objective of the article is methodology presentation to identify distribution of elementary reliabilities (Design reliabilities) and to discuss variant solutions which lead to equalize service life and design reliability of all gears in planetary gear set. The case study for this kind of analysis is selected planetary gear unit for bucket wheel traction of bucket wheel excavator.
