The invention relates to a driving mechanism used primarily to actuate iron fittings and locking devices of doors and windows, that includes a casing, a force application device provided with a connection piece, a first driving subassembly that includes a driving gear and is connected to the connection piece of the force application device, as well as one or more power transmission pieces being in momentum transfer connection with the first driving gear of the first driving subassembly, while a motion transfer subassembly provided with one or more cogged push-elements as well as a second driving subassembly provided with a driven gear are inserted between the driving gear of the first driving subassembly and the power transmission piece. The characteristic feature of the invention is that the driven gear (51) of the second driving subassembly (5) is composed of two or more rolling wheels (51a) turned away relating to each other by an angle less than one pitch and/or the driving gear (31) of the first driving subassembly (3) is composed of two or more component wheels (31a) turned away relating to each other by an angle less than one pitch. |
