ABSTRACT:
The invention relates to an adjustable force transmission arrangement in a big diesel engine for accomplishing force transmission from a crankshaft (9) of the engine by means of gear wheels to at least one camshaft (11). The arrangement includes a first gear wheel (1), which is in connection with the force transmission of the crankshaft (9), and a second gear wheel (2), which is in connection with the force transmission of the camshaft (11), said gear wheels (1,2) being arranged adjacent to each other and arranged in force transmitting connection with each other through a friction surface (5). In accordance with the invention the arrangement comprises a guiding element (3), which is supported by means of a separate slide bearing element (7) to the engine block (6) so that it is guided both in the radial and in the axial direction. The guiding element (3) is arranged to be fixed by means of one or several screw bolts (4) or the like to said first gear wheel (1) so that said second gear wheel (2) is positioned between the first gear wheel (1) and the guiding element (3) and receives from these pieces its guidance also in the radial direction.
