Abstract
The star-shaped internal geared wheel ( ) of a harmonic drive ( ) consists of individual tappets ( ) which are displaceably interconnected by a retainer ring ( ) which circles them at approximately half the height of the tappet shaft, so that they form a single part that can be handled. The inner front end ( ) of the tappet shaft, which is thermally dimensionally stable, is provided with a guiding shoe or at least provided with a slide-resistant coating opposite a radially elastically compressible head ( ). The internal geared wheel ( ) is produced as a one-part plastic injection-moulded element in a multiple component method, with a thermally dimensionally stable foot ( ), support ring arms ( ) which are elastically moulded onto the respective dimensionally stable and extremely resistant tappet shaft and head walls ( ) consisting of different plastics.
