Definitions
- the invention relates to a device for supporting a marine engine on a motor foundation of a ship according to the preamble of claim 1.
- Marine engines such as marine diesel engines are supported on a motor foundation of the ship by means of appropriate devices.
- devices known from practice for supporting a marine engine on a motor foundation of a ship have a stop device and a catching device. These facilities are for storage, but the storage itself is done on the special known storage elements.
- the stop device is also referred to as a stopper and serves to limit a relative movement between the engine foundation and the ship engine, in particular at normal loads due to sea conditions.
- the catching device which is also referred to as a fishing hook, serves to fix the marine engine on the engine foundation especially at high loads due to distress. Thus, especially with strong rolling motions or high heeling angles as well as extreme shock loads, a release of the marine engine from the engine foundation must be safely avoided.
- the stopper and the catcher are designed as separate assemblies. For the stopper small games are desired and a hard rubber coating of the stopper is preferred to prevent the relative movement between the
- the present invention seeks to provide a novel device for supporting a marine engine on a motor foundation of a ship.
- This object is achieved by a device for supporting a marine engine on a motor foundation of a ship according to claim 1.
- the stopping device and the catching device are jointly provided by a stop-catching unit.
- the stop device and the catching device are formed as a common unit, namely a stop-catch unit.
- a stop-catch unit In this way, both the requirement for a slight relative movement between the marine engine and the engine foundation at sea and on the other hand, the requirement for sufficient freedom of movement of the engine in case of shock can be taken into account.
- the stop-catch unit also allows, if appropriate, an overshoot of the hammering movements that are effective for seaward movements without excessive forces being built up.
- the function of a so-called stopper and a so-called fishing hook which are made available by separate assemblies in devices known from practice, are accordingly realized according to the invention by a common stop-catch unit.
- the stop-catch unit has on both the port side and on the starboard side of the marine engine at least one subunit of a cantilever arm acting in the vertical force direction and a cantilever arm acting in the horizontal force direction, wherein the cantilevers each at a clamped end are fixed independently of each other immovable and non-rotatable on a housing of the respective subunit.
- a secure fixation of the marine engine on the engine foundation can be ensured both at low loads as a result of a sea state as well as high loads due to shock and distress situations.
- the cantilevers on the opposite end of its clamped end to the ship engine facing, in sea conditions elastically deformable attacks, wherein the cantilevers are plastically deformable in shock and distress situations. Due to the plastic deformation of the cantilevers is avoided that in shock load cases build up so high forces that either the housing of the stop-catch unit itself or its screw are destroyed with the foundation or motor-side structural parts and dissolves as a result of the ship engine from the engine foundation. At extremely high loads, the ship's engine can thus be held securely on the engine foundation.
- the cantilevers are supported on a side facing away from the marine engine by supporting elements, wherein the support elements increasingly stiffen the respective cantilever with plastic deformation of the respective cantilever with increasing plastic deformation.
- a progressive force-displacement characteristic is specified with respect to the deformation of the cantilevers.

- the support structure 5a, 5b, 6a, 6b can begin at the clamped end of the respective cantilever 2a, 2b, 3a, 3b instead of tangentially also at a small angle to the cantilever.
- This angle can be between 0 ° and 4 ° (old degree) - the large value applies to the large distance value d (20%) at the free end.
- the cantilevers 2 a, 2 b, 3 a, 3 b are subjected to plastic deformation at high loads as a consequence of simultaneously occurring swellings and shocks, as well as in the event of distress.

It is therefore necessary to produce a tensile test of the semifinished product used and to record from it by tensile test the force elongation behavior.
- the measure of the width B is then adapted to the expected load of the corresponding cantilever and adapted to the semi-finished product used. LIST OF REFERENCE NUMBERS
