The present disclosure relates to an arrangement in an articulated joint of a work machine wherein at least two machine parts are rotatably fastened to each other with a conical sleeve shaft joint in which a conical sleeve is pressed against a conical sleeve shaft by an intermediate plate. This intermediate plate includes members for receiving a channel and for connecting the channel to a lubrication channel. The members are formed on the intermediate plate's outer casing which connects a counter-surface to a pressing surface on the side of the conical sleeve to provide a continuous passage for the conical sleeve shaft of the articulated joint.
