Description
Technical field
The invention belongs to shipboard vertical pivot internal combustion engine shafting thrust technical field, used more particularly, to a kind of shipboard
Vertical pivot Diesel Shafting thrust structure.
Background technology
Shipboard is that one kind is suspended on boat, on ship stern trimming flag, can promote boat, also known as the detachable power set of ship navigation, ship
Outer machine, outboard motor, on-hook, are mainly made up of vertical pivot internal combustion engine and transmission, operation, suspension arrangement and propeller etc..Shipboard
With compact conformation, lightweight, convenient disassembly, simple to operate, noise is small the features such as, it is adaptable to make in inland river, lake and coastal waters
With.It is commonly used in military affairs and performs scouting, log in, cross a river, going on patrol, on boat, ship and the raft of pontoons of task such as lifesaving.Civilian racing boat, trip
Ship, short-distance transport ship and fishing boat can also be used.Shipboard with using two-stroke gasoline engine internal combustion engine more, minority for diesel engine and
Motor, power bracket is 0.74~221 kilowatt, and has continuous lifting trend.
Current shipboard is mainly two-stroke or four-stroke gasoline engine with vertical axis internal combustion engine, because its is simple in construction, heat
Load is low, cylindrical implosion hair pressure≤11MPa, the relatively low feature of structural member load.After gasoline shipboard is arranged vertically using bent axle
Generally prevent bent axle, camshaft and movement parts from excessive axial movement value occur as thrust using needle bearing.
Diesel engine is higher due to its load, cylindrical implosion hair pressure >=17.5MPa, and shipboard vertical axis diesel engine is full
The high explosion pressure of foot, main force support structure uses reciprocating part in the higher material of coefficient of intensification and structure, same internal combustion engine (bent
Axle, piston) higher level material is also used, not only complicated and its rotary inertia is much larger than gasoline engine.Shipboard diesel oil
Bent axle, the big shafting of camshaft two use vertical disposition in machine structure design, and piston rod uses horizontal arranging mode, this
Frame mode, which changes, proposes higher requirement for high load capacity diesel engine load-carrying construction axial thrust form.
Conventional engine is because the shaftings such as bent axle, camshaft are using horizontally disposed, in order to prevent bent axle in operation process
With body direct friction, the axial movement value of control bent axle is engine design key technology, if bent axle axial movement value is excessive
Or it is too small, all thrust plate inordinate wear can be caused to form chain damage, cause bent axle to destroy piston rod with body direct friction
With the axial movement track of bent axle, so as to cause body, bent axle, connecting rod to damage, will more seriously engine output end be caused to be driven
Case damages, therefore excellent thrust structure can not only improve engine reliability, while also can increasing service life of engine.
Horizontal internal combustion engine thrust plate is two panels hemisphere format up and down, and movement parts are primarily subjected to carry out spontaneous combustion in the course of the work
Expect the vertical surface pressure broken into, driving toggle does circumferential movement, so that power output.Its horizontal direction thrust knot
Structure is mainly using thrust plate come limit value shafting horizontal direction play.Vertical axis internal combustion engine cloth is postponed, because shafting rotates from heavy-duty machine
Reciprocal inertia force, job requirement can not be met by carrying out thrust with rolling bearing according to vertical axis gasoline engine.
The content of the invention
In view of this, the present invention is directed to propose a kind of shipboard vertical pivot Diesel Shafting thrust chip architecture, perpendicular to improve
High explosion pressure ability is resisted in the thrust of shaft internal combustion engines shafting, solves vertical axis Diesel Shafting shifting amount control difficult problem.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of shipboard vertical pivot Diesel Shafting thrust chip architecture, including shafting, load-carrying construction and annular thrust piece, institute
Connection boss insertion the load-carrying construction such as body, cylinder cap of shafting bottom are stated, between the both sides edge and load-carrying construction that connect boss
The annular thrust piece is set, and the annular thrust piece outer circumferential sides center is provided with circumferential even distribution type asphalt channel and annular
The position of opposed annular groove is provided with grease channel on groove, the load-carrying construction, and the extraneous lubricating oil of grease channel connection is described
Grease channel is fitted close to form voltage stabilizing oil pocket with annular groove, and extraneous lubricating oil is entered by lubricating oil pipeline under pressure
Enter in voltage stabilizing oil pocket, then shafting is entered with the fit clearance of annular thrust piece, forming sliding axle by even distribution type asphalt channel
Hold.
Further, the shafting coordinates with annular thrust piece for gap.
Further, the even distribution type asphalt channel connection annular groove on the annular thrust piece and annular thrust piece and shafting
One side surface of contact.
Further, the shafting be vertical pivot engine block in bent axle shafting or with camshaft shafting, the load
Structure is located at the corresponding vertical pivot diesel body structure of shafting and air cylinder head structure.
Relative to prior art, the present invention has the advantage that：
The present invention cooperatively forms gap with annular thrust piece with shafting, under lubricating oil pressure effect after filling fit clearance
Circulation oil film type sliding bearing is formed, monoblock type has the advantages that high intense, high anti-explosion pressure, high reliability.
