Abstract

In a sun-and-planet toothed wheel gearing the width of the tooth spaces of the toothing of the hollow wheel is preferably made three times larger than at a common toothing with substantially the identical widths of the teeth and tooth spaces. Such a inventive toothing can be produced specifically simple and precise by means of non-cutting methods, preferably an impact rolling.
