An internal combustion engine for driving a propeller shaft is composed of a rearmost main bearing of the internal combustion engine arranged between the throw of a crankshaft and a thrust cam inside a thrust bearing. A thrust segment(20) is arranged between a forward facing sliding face(22) on the thrust cam and a rearward facing supporting face(18) on a fixed type main bearing housing. Within a circumferential area, the thrust cam has a rotationally symmetric arc shaped recessed part(28) extending radially inward to the position of a height without exceeding an intermediate portion of the thrust segment (20).
Description
Technical field
The present invention relates to a kind of internal-combustion engine that is used to drive screw shaft, main bearing place in its rear-most end, it has a thrust-bearing, on the axial direction of bent axle, described main bearing is positioned between the footstalk of a bent axle and the propelling cam of described thrust-bearing (thrust cam), this propelling cam can rotate with described bent axle, thrust bearing shoe be arranged on propelling cam axially forward slip surface and the internal-combustion engine base plate described between axially backward the supporting surface of stationary axle bearing of main bearing.
Background technique
In internal-combustion engine, a such thrust-bearing is integrated in the base plate of main bearing of engine rear-most end, can motor is shortened.This internal-combustion engine generally is the master motor of large ship.Described large ship is such as being Container ship.In this internal-combustion engine, very large moment of torsion must be passed to propeller cavitation from motor by screw shaft.When propeller cavitation promotion boats and ships advanced, propeller cavitation was given power forward of screw shaft, and this power passes to engine foundation by described base plate in described thrust-bearing.
Power transmission from the running shaft to the base plate is undertaken by thrust bearing shoe, and thrust bearing shoe is static with respect to the supporting surface of main bearing seat basically.Slip surface on the propelling cam slides on the supporting surface of thrust bearing shoe, and lubricant film is maintained between this supporting surface and the described slip surface by means of the lubrication system of thrust-bearing.
Each thrust bearing shoe is adjusted with respect to described propelling cam separately, the total load ability of thrust-bearing be each thrust bearing shoe load carrying capacity and.Therefore, the load carrying capacity of wishing described thrust bearing shoe reasonably evenly distributes when work, may be the comparison difficulty in this thrust-bearing in being integrated in main bearing, because in the fan-shaped part that make progress relative, do not have thrust bearing shoe with dismountable top of main bearing.Therefore, the part that makes progress of current propelling cam is not subjected to the supporting of thrust bearing shoe in the axial direction.
Summary of the invention
The objective of the invention is to improve the load carrying capacity of the thrust-bearing in the internal-combustion engine.
For this reason, internal-combustion engine of the present invention is characterised in that described propelling cam zone around has a rotational symmetric arc groove, and this groove radially inwardly extends to the neutral position of thrust bearing shoe at most.
In the oepration at full load that the load carrying capacity of thrust-bearing is utilized, the described arc groove in the described peripheral region means that in this peripheral region, propelling cam is not pressed to the radially outermost zone of thrust bearing shoe so massively.
At first, this means that thrust center (thrust centre) moves inward diametrically slightly.A transverse wall of the standing part of main bearing and described base plate forms an integral body, and this transverse wall is made by heavy material, and has rib shape stiffening rib.Therefore, the radially innermost zone adjacent with itself and axis hole in the main bearing compared, and the supporting surface rigidity in the zone that it is radially outermost is stronger.Under working load, the zone that the rigidity of supporting surface is stronger is out of shape smaller in the axial direction, and this causes on thrust bearing shoe, tends to have maximum load in its radially outermost zone.Arc groove in the described propelling cam has reduced the radially axial pressure in outermost zone of propelling cam, thereby the stronger rigidity of this area supporting face is compensated.
Secondly, never supported being converted to of described arc groove propelling cam on thrust-bearing provides a kind of more uniform pressure distribution in the supported zone.In the not supported zone of propelling cam, the peripheral region of propelling cam tends to deflection, and along with this peripheral region continues to rotate to supported zone, described deflection reduces, and makes the thrust bearing shoe that is positioned at the front be subjected to extra load.Described arc groove provides the part compensation to this overburdening, and this groove has reduced to act on the thrust loading on the bearing shell, and this is especially because the radially outermost zone that deflection took place of propelling cam is maximum.
If this groove is further extending radially inwardly, surpass the middle part of thrust bearing shoe, bearing shell can transmit the ground maximum thrust and just may reduce, and this is reluctant to see.
Best, described arc groove inwardly extends to 30% radially outermost place of thrust bearing shoe at most, because the radially innermost zone that influenced by maximum thrust just can comprise the big zone of of this thrust bearing shoe like this, this is favourable.
In a kind of preferred embodiment, described arc groove is positioned on the outer surface of propelling cam.It is bigger flexible that this groove makes propelling cam have in radially outermost zone.When the load on the thrust-bearing was low, the pressure on the propelling cam was just too low and can not make the propelling cam distortion, and described slip surface just can be arranged essentially parallel to described supporting surface.When the pressure on the propelling cam was high, because that this groove forms is bigger flexible, the radially outermost zone relative with this groove can be axially to this groove deflection.The thrust loading that described deflection means vast scale is more absorbed by the radially inner side zone of thrust axis watt.Therefore, to be slip surface regulate self shape by self according to the size of load to this embodiment's advantage, makes that to remain on lubricant film between thrust bearing shoe and this slip surface in good condition and have suitable thickness.
In one embodiment, described arc groove links to each other with at least one freezing mixture supplying pipe.By the normally freezing mixture of lubricant oil is provided to described arc groove, the front in the radially outermost zone of propelling cam and the back side obtain cooling simultaneously, thereby can keep lower temperature, thereby help to improve load carrying capacity, can not squeezed away because colder lubricant oil can transmit bigger thrust.Because freezing mixture is not to bring into play lubricating function in described arc groove, delivery rate can be adjusted according to the cooling needs fully.
In one embodiment, the propelling cam in the described internal-combustion engine has a radially outstanding flange, and sprocket wheel is fixed on a position that is positioned at the radial outside of described arc groove on this flange.In some cases, described thrust-bearing is arranged on the chain transmission equipment that drives the camshaft that is positioned at the motor rear end.In this case, flexible that arc groove obtains depend in the radially outermost zone that described sprocket wheel can the limit thrust cam.By described sprocket wheel is fixed on the described flange, this sprocket wheel only is fixed on the described propelling cam in a side of described arc groove, and that the opposite side of this groove has kept fully is required flexible.
In a kind of alternative design, described propelling cam has in the axial direction respectively at two barrel surfaces of arc groove both sides, and two ring parts of a sprocket wheel are respectively fixed on the described barrel surface.Two parts that described sprocket wheel are divided into the resilience (mutuallyflexible) of suitably helping each other have in the axial direction also prevented the flexible counteracting in the radially outermost zone of this sprocket wheel and propelling cam.
Perhaps, described arc groove can be arranged on the axial slip surface forward of propelling cam.But this can cause in the thrust-bearing of unloading, and than bigger in radially innermost zone, this can cause oil film very thick in the radially outermost zone of low-load to the distance between slip surface and the supporting surface in radially outermost zone.Yet this can't cause the problem moved.When thrust-bearing at full capacity, and radially outermost regional specific diameter gets more for a long time to innermost regional deflection, the distance between slip surface and the supporting surface will be more even, this even distribution on thrust bearing shoe that can promote to load improves load carrying capacity.
Because load upwards is more evenly distributed in the footpath of thrust bearing shoe, the present invention is very large, and Continuous Maximum Rating is at least in the two-stroke crosshead diesel engine of 40000kW and is particularly useful.Because generally will be under the slow-speed of revolution, 70 to 200rpm the rotating speeds very high power of output down for example, end thrust can be high, and thrust-bearing is corresponding to have very large-area thrust bearing shoe.Thereby the oil slick thickness between bearing shell and the slip surface is less with respect to the size of thrust bearing shoe, and, the skewness of thrust on bearing shell, this has remarkable influence to load carrying capacity.
