Embodiment
The main application of the present invention is the two-stroke large diesel crosshead engine.Such motor is widely used as shiphoard machinery system.The basic structure of this type of motor and working method are well-known.
Two-stroke large diesel crosshead engine shown in Figure 1 comprises the cylinder 1 of a plurality of front and back series connection, and cylinder respectively has a cylinder liner 2 that is provided with suction port, adorns a piston of attaching troops to a unit 3 in the cylinder liner.Piston is connected with crosshead 5 by a coaxial piston rod 4, and crosshead moves up and down equally with piston 3 and is connected with bent axle 7 by connecting rod 6.This bent axle is in the bottom 8 of engine bearer.Installation one comprises the intermediate structure 9 of crosshead 5 on bottom 8, and cylinder 1 is placed on this intermediate structure.Piston rod 4 passes the wall that intermediate structure 9 upwards refers to, for this reason, wall is provided with a current lining 10.The part of above mentioned engine bearer links together by the pull bar 23 that only schematically illustrates by its center line in Fig. 1.
Crosshead 5 has two pairs along the horizontal slide block 11 respect to one another of motor, and they abut on the slide rail that sets respectively 12 and by slide rail and guide.Slide block 11 and slide rail 12 are shaped on the slip surface 13,14 that faces one another.It is the chamber that is respectively applied for a crosshead 5 on boundary that the intermediate structure 9 of engine bearer is provided with the cross wall 15 of engine bearer or parallel with it end wall below cylinder 1.Slide rail 12 is installed on adjacent separately cross wall 15 or the end wall and by side direction intensifier 16 and is bearing on the wall.Intensifier is with the slide rail 12 of attaching troops to a unit and cross wall 15 or the end wall border that to constitute a cross section respectively be leg-of-mutton passage, and above mentioned pull bar 23 can pass this passage.Slide rail 12 can extend along the whole height of intermediate structure 9 together with the intensifier 16 of attaching troops to a unit, but is being not described this situation for the purpose of simplifying view among Fig. 1.
The slip surface 13 of slide block 11 and the slip surface 14 of slide rail 12 are designed to the smooth surface of not segmentation, and they are supplied to lubricant oil in order to obtain the good operation characteristic.Set for this reason lubricating fitting comprises and can produce the beam 18 of aiming at slide rail 12 slip surfaces 14 by oil nozzle for the oil nozzle 17 of lubricant oil.Oil nozzle 17 is located in the zone of slide rail 12 upper end portions in this example, here is installed on the wall that intermediate structure 9 upwards refers to.Additionally or with it differently also can be each slide rail 12 set a plurality of along its height profile oil nozzle and/or be located at oil nozzle on the crosshead 5.
Outside stop, extend with respect to piston or crosshead axis tilt ground from the power that connecting rod 6 transmits to crosshead 5.The horizontal component of this power is extended on the contrary with its direction in up stroke in downward storke.Following and implementing the crosshead 5 downward and pistons reciprocating 3 that makes progress, correspondingly by stroke alternately with along the horizontal component direction that is applied to the power on the crosshead 5 from connecting rod 6 always in front those slide blocks 11 be pressed on and attach troops to a unit on the slide rail 12 of these slide blocks, be in the slide block 11 and slide rail 12 unloadings of relative position during this period.The size of impacting force changes in each stroke, because be applied to the size of the horizontal component of the power on the crosshead 5 from connecting rod 6, depend in the active chamber that with piston 3 is the boundary, to follow the effective pressure that journey changes and the oblique position of connecting rod 6, and thereby depend on crank shaft angle and depend on crosshead 5 position in every trade journey or the downward storke scope thereon thus.
The face that is in contact with one another between slide block 11 and slide rail 12 must be so big, the lubricant film that makes it to be no more than the pressure of permission and can form expectation thickness.Meanwhile, the size that between slide block 11 and slide rail 12, the reactive mutual frictional force itself of moving is depended on the face of contacting with each other.The slip surface 13 of slide block 11 is configurations continuous plane and non-moulding and that a kind of rectangle is arranged, this configuration have with the corresponding height of the height of slide block 11 and with the width corresponding width of slide block 11.Maximum contact face each other is present in following situation,, is placed on slide block 11 on the slide rail 12 of attaching troops to a unit with its whole length all the time that is, also with slip surface 14 collaborative works of its whole width carrying ground with the slide rail 12 of attaching troops to a unit.Maximum area of contact is determined its size according to the maximum impacting force of expection.There is the place of less impacting force to avoid surface of contact mutual between the slide block 11 and the slide rail 12 of attaching troops to a unit oversize in order to make to compare with maximum impacting force in effect, and thereby reduced the resistance of effect of antagonism crosshead 5 motion and the power loss that causes thus as far as possible, the slip surface 14 that makes slide rail 12 along the slide block 11 of being attached troops to a unit in each stroke inswept height by this way and crosshead 5 in the stroke of implementing with compacted slide block 11 along being complementary by the change procedure of mutual impacting force between slide block 11 and slide rail 12 of the inswept ramp area expection of slide block 11, that is, slip surface 14 is contacted by slide block, the area of carrying increases equally with the impacting force that itself changes and reduces.
Can obtain optimum efficiency in this case; promptly; the slip surface 14 of slide rail 12 is designed to; make pressure between the slip surface 14 of the slip surface 13 of slide block 11 and the slide rail 12 of attaching troops to a unit during the stroke that the compacted slide block 11 of crosshead 5 usefulness is implemented; along the whole length that is in contact with one another stroke is constant basically; so on whole stroke, also can obtain a kind of predetermined lubricant film, thereby guarantee especially little resistance to motion and special protectorate work near constant thickness.This instruction can take measures to realize simply, and the carrying width edge that makes slide rail 12 slip surfaces 14 shown in Fig. 2 to 6 is by the length of the stroke S of slide block 11 processes, and the change procedure that mutual impacting force is expected along this trip between slide block 11 and slide rail 12 changes equally.
Represented the position of slide block 11 among Fig. 2 in top dead center of representing with dot and dash line and lower dead center.When top dead center on the slide block seamed edge and when lower dead center the distance between the seamed edge under the slide block, the length of the stroke S that moves past at each stroke by slide block 11 that has mentioned above equaling, hereinafter it is called contacting travel, and it equates with height that the length of crosshead 5 strokes is added slide block 11.
Be in the Base Design with Fig. 2 and 3, slide rail 12 has identical width b on its total length.Therefore provide slide rail 12 parallel side, slide rail 12 at the regional internal fixation of a side on the adjacent cross wall 15 of engine bearer, and slide rail at the regional internal support of its another side on intensifier 16.The slip surface 14 of slide rail 12 is stretched from that side that faces cross wall 15 always and is reached that edge that slide rail 12 is parallel to cross wall.Slip surface 14 is in the edge 20 of relative position and is not parallel to cross wall 15 and extends, but is designed to curve, and this curve changes with the function relation of slide block 11 positions along contacting travel S according to the impacting force that a compacted slide block 11 is applied.Therefore, the Effective face width of slip surface 14 changes along contacting travel S, and wherein Extreme breadth equals the width b that slide rail 12 has been mentioned in the above.The width of slide block 11 is equally corresponding to width b.Here, slip surface 14 is the boundary with the zone 21 that sinks with respect to its upside.
This curve can be removed material by part and make, and for example by milling or corrosion etc., maybe can make by the chipless distortion, for example by compacting.Sinking with degree of depth t can be clear that by Fig. 4.Sinker area 21 contacts therewith in the time of on the slip surface 14 that the degree of depth t that sinks is designed to make slide block abut in slide rail 12 with its slip surface 13.Here submergence depth is that 1mm is just much of that fully.Transition between sinker area 21 and the slip surface 14 that do not sink is cavetto rightly, and this can make seamed edge district off-loading.
For the slip surface 14 that constitutes curved edges 20 required in form for milling the processing of system process, corrosion process or extrusion process etc., can on new or already used slide rail, implement.Therefore also might make the slide rail of existing crosshead engine be equipped with the slip surface that designs by the present invention in an advantageous manner.
Based on the slide rail 12 of Fig. 2 stand under load when the downward storke.Maximum impacting force appears near top dead center in downward storke.Impacting force then reduces, and reaches minimum in about tail end on contacting travel S top 1/3rd.Then this power increases once more, but does not reach the high value of upper zone, drops to a low value then near the end of contacting travel S again, and this value equals above-mentioned minimum substantially.The edge 20 that constitutes slip surface 14 width borders changes by same mode, that is to say that the width of slip surface 14 increases and subtracts along contacting travel S, and Extreme breadth is consistent with the top width b that has mentioned in this process.
Based on the slide rail 12 of Fig. 3 stand under load when the up stroke.The impacting force of being transmitted by the slide block 11 of attaching troops to a unit reaches a maximum value that continuity is long here near lower dead center, then drop to a minimum value that is positioned at the lower end on contacting travel S top 1/3rd substantially, and then near top dead center, be increased to maximum value.The edge 20 that constitutes slip surface 14 Effective face width borders changes by same mode, that is to say that the width of slip surface subtracts and increases along contacting travel S, and Extreme breadth is still corresponding to the width b of the top slide rail of having mentioned in this process.
The zone of playing slip surface 14 effects of comparing projection in both cases with the zone 21 that sinks all constitutes a continuous surface, and this surperficial side terminates on the cross wall 15 along seamed edge always, and opposite side is the boundary with curved edges 20.Because slip surface 14 does not have any existence discontinuously along its length, so lubricant film inside that forms in the gap between the slip surface 13 of the slip surface 14 of slide rail 12 and the slide block 11 of attaching troops to a unit, set up a bigger oil film pressure along the height of slide block 11, therefore have smaller height just enough for reaching predetermined pressure slider 11.With top combining of having illustrated, caused the minimizing and thereby improve the efficient of motor and prolong its working life of wearing and tearing of the minimum friction forces of effect of antagonism slide block 11 motion and expection along variable slip surface 14 width of contacting travel S.
Fig. 5 represents to constitute the another kind of possibility of sunken regions 21.Here, the support of the intensifier of in form mentioning for preface 16 that is respectively that slide rail 12 sets on purpose is out of shape in order to make slide rail 12 under the effect of pull bar 23, is shaped on appropriate elastic groove 24.In fact they constitute one type of intensifier 16 weakening.Here the slide rail 12 that extends along engine bearer intermediate structure 9 whole height passes through pull bar 23 compression chords.Place in affiliated intensifier 16 flexible holes 24, slide rail 12 is in that be subjected to can be perpendicular to longitudinal bending under the corresponding load that is caused by adjacent pull bar 23.And in the place of not establishing elastic groove 24 or additionally being strengthened by the slide rail that intensifier 16 constitutes, slide rail 12 is less or not crooked.Can obtain the support profile of expectation in this way in slip surface one side.
In order to obtain the elasticity of intensifier 16 expectation, the configuration of elastic groove 24, that is its length and/or width can change.This realizes in Fig. 5, wherein, set elastic groove 24 causes the slip surface 14 of a carrying as shown in Figure 2 and the zone 21 that sinks in the intensifier 16 that is drawn in the right, and set elastic groove 24 causes the slip surface 14 of a carrying as shown in Figure 3 and the zone 21 that sinks in the intensifier 16 of on the left side.But also it is contemplated that, reach same or similar effects by the distribution that changes identical elastic groove.The degree of depth of elastic groove 24 also can change.Their grooves that can be designed to connect or that do not connect.Under any circumstance elastic groove 24 all should design and be arranged as, and makes the distortion of possible thus slide rail 12 cause the support profile of expecting.
The elastic groove 24 of having mentioned type above can adopt as substitute mode or the additional measure of conduct by measure shown in Fig. 2-4, as with dashed lines hint among Fig. 4.
Certainly also all right, make slide rail 12 unnecessary zones not only sink but whole removal as slip surface.Fig. 6 has represented this form of implementation.Therefore, here slide rail 12 has a kind of variable width along contacting travel S, and wherein the width of slip surface 14 follows journey S corresponding to slide rail 12 the width there itself.What constitute slip surface 14 is fixed on the edge 20 that cross wall 15 above it is in that lateral boundaries of relative position with slide rail 12, can make by cutting or flame cutting process.Be in the zone at edge 20, to stipulate cavetto here for what reach that a kind of shielded work also can be appropriate.Slide rail 12 exceeds the end portion that contacting travel S end stretches out can a constant width with the width that exists in contacting travel S associated end here respectively.By the recess 22 at edge side set in pressing the form of implementation of Fig. 6, certain that causes slide rail 12 weakens.Therefore, this slide rail 12 must have one with Fig. 2 with slide rail shown in 3 design compare more bigger thickness.
In Fig. 2,3 and 6 edge 20 along contacting travel S follow exactly one with the expection the corresponding curve of power change procedure.But also it is contemplated that a kind of change procedure that is similar to above-mentioned curve of employing for the ease of making, as the edge 20 ' in dashed lines hint among Fig. 6 schematically illustrates.
