Beschreibung
Zusammenfassung:	The invention relates to the welding engineering, in particular to the welding wire feeding mechanisms and may be used in the automatic and semi-automatic welding machines. The mechanism contains an electric motor, a planetary precession reduction gear, drive and pressure rollers. The reduction gear includes a satellite gear installed onto the crank, central wheels: fixed and mobile joined with the driven shaft. The drive roller is freely installed onto the body and it is joined with the driven shaft.The result - an increased bearing capacity, the possibility of using an expanded range of welding wire diameters from 2 up to 12 mm.Claims: 2Fig.: 4
