Description

Method and device for assembling elastically mounted power machines

The invention relates to a method for elastic assembly stored power machines, in particular the main engines of ships, and the information required to carry out the procedure Facilityo

With the elastic mounting of electrical units with Piston engines has recently become the arrangement the rubber isolators at a certain angle of inclination to the horizontal. The one with such storage High-speed machines of lighter design occurred The advantages of damping mechanical vibrations and structure-borne noise also led to the use of this arrangement for electrical units with medium-speed machines heavier construction In recent times ship's main engines have also been used larger power units in this way elastically mounted · in the case of the Monbage elastically mounted Ship's main engines result from taking into account the specific properties of the isolator rubber - in particular its flow behavior - a special problem because here a mechanical power transmission to rigidly mounted Shaft systems or gearboxes are successful due to the flow behavior the insulating rubber takes place after loading the rubber insulating laboratory an initially sable, lowering of the rubber insulation laboratories over the duration of the exposure. With Sücksichb up the later operational security of the GfcSfmfcanlage, in particular

the coupling arranged between the elastically mounted motor and the rigidly mounted shaft system or gearbox, the alignment of the motor to the shaft system can only be done after the flow of the isolator rubber a certain preload time has been completed to a certain extent. The preload on the rubber isolators takes place with the operating mass of the engine, usually through Put the motor down on the rubber insulators, taking care of the installation angle of the rubber insulators must be that horizontal displacements of their foundation-side Metal plates or "feet are excluded" Ss elastically mounted main ship engines are known, where the engine base frame and the ship foundation the installation angle of the Rubber insulators have corresponding areas between which, after roughly aligning the motor base frame to the shaft axis, the rubber isolators in the unloaded state can be fitted and installed with IT filler pieces. After weaning of the motor, the rubber isolators are preloaded and, after the specified preload duration, the alignment and the Fixing of the motor on the mofcor base frame similarly rigid of engines installed on ship foundations «, In a further known embodiment, the engine and engine base frame are as a fixed unit before being introduced into the ship mounted and the already attached rubber isolators, also arranged at a certain angle, on the foundation side Equipped with counter bearings that have horizontal base plates. A is used as an aid to assemble this version

special dismountable one equipped with cross connections Mounting frame, which is connected to the untouched counter bearings of the rubber insulation laboratories, which must not be braced in this case, is screwed. The preload on the rubber isolators takes place by lowering the Monba frame onto the ship's foundation.

If the pre-blasting time has been reached, it takes place aligning the motor to the shaft system, with the Mobor still remains on the mounting frame. Do the alignment are between the foundational counter bearings and fitted to the support bars of the Mils foundation, the counter bearings are attached to the foundation in the usual way and then the dismantled mounting frame is dismantled. The known versions have the "each part, that a very high effort is required for the assembly of the ship's main engines. The first execution requires a relatively complicated one Ship foundation with inclined supports, increased design effort - rough and fine alignment - as well as double Passport work. The other version avoids the double calibration and fitting work, but requires an additional one relatively complex mounting frame. '

The purpose of the invention is to avoid the said specialist parts

The invention is based on the object of a method and a device for assembling elastically mounted power machines, in particular of the main shipbuilders,

about the technological effort and the scope of necessary auxiliary equipment with uncomplicated. Significantly reduce _{foundation training Wj}

According to the invention the object is achieved in that each the upper counter bearings are rigidly connected to the lower counter bearings in the unloaded state of the rubber insulators that after setting down the machine with the footplates of the lower counter bearing on the foundation support after lateral fixation of the lower counter bearings by means of stoppers attached to the foundation supports in a known manner. and after lifting the rigid connection of the upper and lower counter bearings, the preload takes place that after their Completion and restoration of the rigid connection of the upper and lower counter bearings in the loaded state of the Rubber isolators the alignment of the machine to the shaft system is made, that afterwards in the usual V / eise the lower Counter bearing by means of adapters and screws on the foundation supports and the rigid connection between the upper and lower counter bearings is finally broken

The device according to the invention for carrying out the method provides .vor that one or more mounting brackets are preferably symmetrical to the rubber insulator or to several A common lower counter bearing attached rubber insulators are arranged, which are preferably vertical Faces of the upper counter bearing and rest on preferably horizontal surfaces of the lower counter bearing, with

the upper and lower counter bearings are detachably connected, wherein the releasable connection of the mounting bracket with the upper counter bearings within a certain vertical Area can be produced.

A special embodiment of the device according to the invention provides that each lower counter bearing is equipped with at least one forcing screw *,

The advantage of the solution according to the invention is that ■ the technological effort for the assembly of elastically mounted Power machines "as well as the expenditure on special facilities lowered for assembly and complexity the assembly of these machines can be reduced practically to the level of rigidly installed power machines.

The invention is shown below using an exemplary embodiment are explained in more detail. The accompanying drawing shows in
