Abstract

In this paper the structural analysis of a planet carrier was carried out for the design optimization of a slewing reducer used in tower cranes. The stress changes of the planet carrier according to the tolerance of interference fit were investigated, and the strength was evaluated on the basis of the stress level. The analysis results showed that the tolerance of interference fit have an important influence on the stress level of the planet carrier. To guarantee the static safety of carrier, the tolerances of carrier pinhole and planet pin as well as loading level exerted on the planet carrier should be determined considered correctly.
