    专利说明:

    The invention relates to mechanical engineering, in particular to engine building, and can be used in mechanisms of balancing inertia forces of the second order.
    Known diesel internal combustion engines containing a base plate, a crankcase located on the base plate, bearings for the shafts of the balancing mechanism of second-order inertia sip of inertia installed in the bearings, and connected to the crankshaft, on one side of which are placed ^ devices for connecting the drive.,, and the other side is free £ 1}
    However, in this embodiment of the engine, the balancing mechanism is installed at a considerable distance from the crankcase and its support is attached directly to the foundation plate. In this 2Q case, the engine occupies a significant area of the engine room, resulting in bending moments on.
    In addition to completing, tearing moments can cause unwanted vibration.
    The purpose of the invention is to reduce the size of the engine by reducing the center distance between the shafts of the balancing mechanism.
    The goal is achieved in that the base plate is made with support for at least one of
    In FIG. 1 shows the proposed engine, a longitudinal section; in FIG. 2 - same, left view.
    The diesel internal combustion engine contains a foundation plate. ·, That 1 (Fig. 1), a crankcase 2 placed on a foundation plate 1, bearings 3 and 4 for shafts 5 and 6, respectively, of a second-order inertia balancing mechanism installed in thrust bearings (not shown) and connected to the crankshaft 8, on one side 9 of which devices 10 (Fig. 2) for connecting a drive (not shown) are placed, and the other side 11 (Fig. 1) is made free.
    The base plate 1 is made with a support 3, for at least one of the shafts 5. The support 3 is placed either on the side 9 or on the side 11 of the crankshaft 8. The supports 3 and 4 are made with a recess (not shown) to accommodate thrust bearings (not shown) of the shafts 5 and 6 of the balancing mechanism 7. The shafts 5 and 6 are provided with unbalanced masses 12 and 13. By means of the chain drives 14 and 15, the shafts 5 and 6 are kinematically connected with the crankshaft.
    When the engine is running, the crankshaft 8 through chain gears 14 and 15 drives the shafts 5 and b into rotation with double frequency. The unbalanced masses 12 and 13 during rotation balance the inertia forces of the second order.
    Since the base plate 1 is made with supports 3 and 4, this allows to reduce the dimensions ’of the balancing mechanism 7 by reducing the interaxial distances between the shafts 5 40 and 6, and therefore the area occupied by the engine in the engine room of the vessel.

    The support is placed either from the drive or from a free crankshaft, and the support is made with a recess to accommodate the bearing of the balancing mechanism shaft.
