ABSTRACT:
In an internally meshing planetary gear structure with trochoidal tooth profile, the input shaft and the eccentric body are coupled so that radial displacement is possible and that the displacement between the eccentric body shaft and the input shaft is absorbed. In addition to this, positioning members or thrust bearings are used to suppress the axial movement or the inclination of the eccentric body or the external-toothed gears.
