    摘要： A planetary drive containing two gear wheels with differing numbers of teeth and a radially flexible planetary wheel in engagement with these gear wheels. The planetary wheel has internal teeth and external teeth and is arranged at least partially in an annular gap between a hollow wheel and a sun wheel. The planetary wheel is forced by a cam element into the gaps between the teeth of the gear wheels in engagement zones. There are four engagement zones distributed around the circumference of the planetary wheel in which the teeth of the planetary wheel engage either the hollow wheel or the sun wheel. A roller bearing is provided between the cam element and the planetary wheel. The drive has a short axial structural length and a low manufacturing cost, assures uniform loading of the gear teeth, and enables the reduction ratio to be selectively predetermined throughout a large range.
