Description

A kind of feet bolt hole localization method of marine main engine and gear-box
Technical field
The invention belongs to shipbuilding technical fields, and in particular to the feet bolt of a kind of marine main engine and gear-box Hole localization method.
Background technique
The axially position deviation of marine main engine and gear-box will directly determine the installation accuracy (producer of geislinger coupling It is required that the axially mounted spacing tolerance range of host output end and gear box input are as follows: ± 0.5mm), if this precision is lost Control, it is most likely that cause torsional oscillation exceeded phenomenon when shafting operates from now on.Therefore, the axially position deviation of host and gear-box will Directly affect the service performance of geislinger coupling.In addition, the located lateral deviation of host and gear-box will will cause bearing Eccentric operating to influence the service performance and service life of bearing, and then influences the propulsive efficiency and fortune of entire propulsion system Turn the service life.Therefore, marine main engine and gear-box need to be accurately positioned.
The position of marine main engine and gear-box depends on the position of feet bolt hole, and the positioning of the latter is according to axis The shafting actual center line determined when rudder system looks for middle, on host and gear cage base panel, with scriber and sample punching calibration host It is realized with the center line in gear-box foundation bolt hole.Although the quantity in the foundation bolt hole of host and gear-box is more, The foundation bolt hole of host and gear-box is all located in respective base plane, and relative position is illustrated on drawing, as long as One of benchmark hole site is fixed, and the position in remaining foundation bolt hole can determine, therefore, host and gear cage base bottom The key point of bolt holes scribing line is the position of " finding accurately " datum hole, while need to ensure that the relative position between each bolt hole is closed System.
In general, the oil sump of hull structural design Shi Huiwei gear-box designs a dedicated accommodation space, therefore, gear The axial position of case is determined by the Ship Structure position where it, as long as the axial dimension of entire shafting meets design requirement (in general, the adjustment amount for having ± 50mm using the axle-system axial size of shaft coupling type of attachment), the position of gear-box is also It is relatively fixed.Since the relative position of host and gear-box is determined by the geislinger coupling of both connections, As long as the position of gear-box is fixed, the position of host also therewith depending on.
Problem is main engine foundation panel and gear cage base panel not on one face, and there are differences in height, this is increased by The scribing line difficulty in its foundation bolt hole.Thus, it is necessary to which an object of reference leads to the axially opposing size of gear-box and host It crosses on the object of reference " drawing " to main engine foundation panel, this was on be utilized in main engine foundation panel in the past along foundation bolt hole The line of centres draws steel tape to gear cage base, while founding a straight steel ruler along steel tape on gear cage base panel, leads to It crosses and reads the position scale of straight steel ruler to calculate the position in host foundation bolt hole, but straight steel ruler and gear cage base panel hang down All there is certain uncertainty in straight degree, steel tape and the verticality of straight steel ruler and the straightness of straight steel ruler, this is easy for making Bigger than normal at the accumulated error measured size, deviation can reach 5mm or so sometimes.The key point of problem is to produce deviation often It is not easy to find, after need to waiting until that host and gear-box all lift in place, host and gear-box pair before geislinger coupling is installed It could find, but late how deviation to be eliminated in " rudiment " stage, be just particularly important when middle.
Therefore, it is badly in need of the precise scoring lines method of a kind of host and gear cage base foundation bolt hole.In addition, host and gear Bottom bolt holes quantity it is more (using twin shafting paralleled twin-engine propulsion system host and gear-box foundation bolt quantity up to 200 or so), therefore, the scribble method in foundation bolt hole is directly related with scribing line efficiency.Demarcating each foundation bolt in the past It is to be ensured in foundation bolt hole using the equal characteristic of rectangle diagonal line by the method repeatedly attempted when the relative position in hole The parallel and vertical relation of heart line and center line of shafting and host center line, this way inefficiency and is difficult to ensure precision, Therefore, method is to then getting twice the result with half the effort, based on this present invention by by theodolite, a kind of dedicated subsidiary tooling of L-type and It plans etc. and to cross host and gear cage base foundation bolt hole to achieve the purpose that upgrading synergy.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides the feet bolt of a kind of marine main engine and gear-box Hole localization method, the present invention can be avoided the deviations of host and gear-box, guarantee entire propulsion system installation accuracy and Service performance.This patent is devised for the host during the construction of ship dock, the scribing line operation of gear cage base foundation bolt hole A method of for improving certain type shipowner machine, gear cage base foundation bolt hole scribing line efficiency and precision, for avoiding because of master The vibration damping effect of machine and gear-box deviations and the service performance for influencing entire basic propulsion system, especially Geislinger elastic coupling Fruit.Meanwhile this method is simple and easy to operate, operating efficiency is high, initially puts into the very little and later period and will not generate additional use And maintenance cost.In addition, this method is suitable for similar ship type, versatility is stronger, application easy to spread.Therefore, this method is advantageous This gain and upgrading synergy are dropped in shipyard, embodies the soft power of shipyard, can fundamentally improve the core competitiveness of shipyard.
