Abstract: A gear mechanism includes a rotating input element, a rotating output element, and at least one first force transmission device arranged along a spiral line on a face of the input element. A second force transmission device is arranged along an encircling line on a face of the output element. The interaction of these force transmission devices transmits a turning moment from the input element to the output element, whereby this turning moment effects a rotating motion in the output element so that the rotational speed is lower than the rotational speed of the input element. A rotary encoder may be equipped with a gear mechanism of the aforementioned type.

Abstract: A method and a tool are provided for producing structural parts from sheet metal which have a vault-structured stiffening zone and adjacent, flat connection zones. The starting point for producing these structural parts is vault-structured blanks which are smoothed in the region of the connection zones in the course of the forming, whereas the vault structure is retained unchanged in the region of the stiffening zone. These structural parts are produced by an embossing tool which has a die and a two-piece punch including of a fixing punch and a forming punch. In the process, the blank is first of all fixed relative to the fixing punch in the region of the vault-structured stiffening zone by a fixing element which is in a leading position with respect to the die. The connection zones are then shaped between the punch and the forming punch.
