Clamp joints used in the mining mechanisms of multibucket wheel excavators are the cause of serious repairing problems as well as financial looses. As far as the mining machines of quite difficult to mine formations in KWB Turów are concerned, the most important deficiency of used in these machines clamp joint is a tendency to form the adhesion connection on the surface of clamp of the movable part of yoke to the pin of the buckle wheel shall. Every time pulling down the gear from the shaft causes the shaft surface defect or is not possible to do without damage. Generally after disassembling, shaft and yoke need to be regenerated or exchanged. This is the one of the main reasons, that the project concerning the elaboration of new solution was started from. In the article, the chosen issues of designing the new connection between planetary gear yoke and bucket wheel were presented. In the chosen concept of shaped joint the existing elements of mining mechanism are maximally used. All of the elaborated structural solutions underwent the penetrating strength FEM analysis with taking the way of performing into consideration.
