DOPPELTES PLANETENGETRIEBE MIT VERSTAERKTER VERZAHNUNG FUER EIN MIKROMETRISCHES GELENK, INSBESONDERE VERWENDET IN FAHRZEUGSITZEN.

摘要

Double planet gear in which the teeth (2, 3) of the planet gear having different diameters but a same diametral pitch, or a same tooth diameter (6, 7) but of different diametral pitches, are produced by die stamping to a certain depth from a disc (1) in such a way as to form, in the mid plane of the latter, a central cheek (4, 8) against which the teeth (2, 3 or 6, 7) bear, as a result stiffening each tooth in order to prevent its crushing or its deformation. ……
