The tooth contact stiffness is very important value for calculation of the dynamic properties of the planetary gear drives. This type of gearing has advantage in splitting the force flow into several planet stages. The dimensional or mounting errors can cause that some planets take more load than the others. Application of flexible planetary pins or free central wheel improves the load distribution. But in such cases, the wheels radial motions have to be included in the mathematical model.. The focus of this contribution is to derive the stiffness of this radial connection and to analyze the influence of radial stiffness on planetary gear dynamics.
