For solving the means of problem
To achieve these goals, the crosshead of the crosshead type diesel engine of the present invention adopts the following technical scheme that.
That is, the crosshead of the crosshead type diesel engine of the present invention the first form, has: one end of piston rod and one end of connecting rod are connected into rotating pin；Carrying out sliding and reciprocating sliding part relative to sliding panel, described sliding panel erects setting from the side being fixed on main body side to another side；And connect described pin and the connecting portion of described sliding part, arm is positioned at the described sliding part side of described connecting portion, described arm deviates from the central part on the axis direction of described pin of described sliding part to the axis direction center side of described pin, described connecting portion is configured to, from described pin, the power to described sliding part is applied to the position from the deviation of the described opposite side side of sliding panel described in the mediad of this sliding part, the described opposite side side of whole described sides being configured in described sliding panel of described sliding part.
Owing to connecting portion is configured to, it is applied to, to the power (side force) of sliding part, the position that the opposite side side of the mediad sliding panel from sliding part is deviateed from pin, therefore the application point of the side force on sliding part just deviates to the opposite side side of sliding panel.Thus, the end of the side, side that sliding part is just indexed to sliding panel side, sliding part by the end of the opposite side side of sliding part around application point is indexed to the moment of pin side.Therefore, when side force is applied in crosshead, sliding part just can carry out such displacement: the end of the opposite side side of sliding part conjugates to sliding panel side, and the end of the side, side of sliding part conjugates to pin side, and the displacement of the end of the side, side of sliding part is more than the displacement of the end of opposite side side.This displacement becomes the deformation identical with sliding panel when applying side force.Its reason is, a side of sliding panel is fixed on main body side and erects setting to another side, therefore when applying side force from crosshead, displacement bigger than the side ground flexure of another side.Therefore, the crosshead of the present invention the first form is to make sliding part conjugate accordingly with the deformation of sliding panel being applied with side force, therefore can make the face drops between sliding part and sliding panel.
In the crosshead of the crosshead type diesel engine of the present invention the first form, it is preferable that described arm deviates from the described opposite side side of sliding panel described in the mediad of described sliding part.
Owing to the arm of connecting portion is positioned at the sliding part side of connecting portion, therefore the application point of the side force being applied on sliding part can be determined according to the position of this arm.In said structure, owing to making the opposite side side of the arm mediad sliding panel from sliding part deviate, therefore the end of the opposite side side of sliding part can be made to conjugate to sliding panel side, and make the end of the side, side of sliding part conjugate to pin side.
Further, since determine application point according to arm, therefore in addition to arm, preferably it is not provided with passing to side force the rib etc. of sliding part, only makes arm be connected with sliding part.
It addition, in the crosshead of the crosshead type diesel engine of the present invention the first form, it is preferable that in the side, described side of the arm being positioned at described sliding part side of described connecting portion, it is provided with the notch part formed to another side described.
Owing to being provided with the notch part formed to another side in the side, side of arm, therefore the application point of side force can be made to deviate from the opposite side side of the mediad sliding panel of sliding part.It addition, arm can be allowed with notch part for playing point deformation.Thus, can more successfully make the end of the opposite side side of sliding part conjugate to sliding panel side, and make the end of the side, side of sliding part conjugate to pin side.
It addition, as notch part, preferably R shape is to avoid because repeating the life-span decline that load is brought.
Additionally, in the crosshead of the crosshead type diesel engine of the present invention the first form, it is preferable that the end on the described vibration-direction of described sliding part is the thinner wall section that thickness is thinner than the part beyond this end.
Being made the end of the vibration-direction of sliding part than end with the thin thickness of outer portion, the rigidity making end is lower than the part beyond end.Thus, the side force being passed to sliding panel by the end of sliding part can be reduced, therefore the local that the face between sliding part and sliding panel can be suppressed to press rises.
In the crosshead of above-mentioned crosshead type diesel engine, it is preferable that described thinner wall section is the shape after the face of the side contrary with described sliding panel is removed.
It is removed the thinner wall section of rear shape owing to making the face of the side contrary with sliding panel, therefore can easily be processed.Further, since do not reduce relative to sliding panel slide area form thinner wall section, therefore form thinner wall section while face pressure can not be increased.
It addition, in the crosshead of above-mentioned crosshead type diesel engine, it is preferable that described thinner wall section is the shape after the face of described sliding panel side is removed.
The face that may be alternatively configured sliding panel side is removed the thinner wall section of rear shape.
It addition, the crosshead type diesel engine of the present invention the second form, there is the crosshead of any of the above-described kind.
Owing to having the crosshead of any of the above-described kind, therefore the face drops of sliding panel can be made, can the thickness of sliding panel be done thin, or need not unnecessary strengthening measure, therefore overall weight can be reduced, reduce cost.

Detailed description of the invention
Below, it is explained with reference to one embodiment of the present invention.
Fig. 1 represents the skeleton diagram of the crosshead type diesel engine of an embodiment of the present invention.Diesel engine shown in this figure principally serves as the main frame of Ship Propeling, uses the uniflow scavenging mode of two-stroke one cycle of operation.
This diesel engine has: be positioned at support 20, the frame (main body) 5 being located on support 20 and the cylinder sleeve 21 being located in frame 5 of lower section.These supports 20, frame 5 and cylinder sleeve 21 utilize the multiple stress bolts (not shown) vertically extended and integral by being fastened and fixed.
Cylinder sleeve 21 is provided with cylinder buss 22, is provided with cylinder cover 23 in the upper end of this cylinder buss 22.Reciprocating piston 1 it is provided with in the space formed by cylinder buss 22 and cylinder cover 23.The upper end of piston rod 24 it is rotatably mounted with in the lower end of piston 1.
Support 20 is crankcase, is provided with bent axle 4.The lower end of connecting rod 3 it is rotatably coupled in the upper end of bent axle 4.
In frame 5, it is provided with and piston rod 24 and connecting rod 3 are connected into rotating crosshead 2.That is, the lower end of piston rod 24 and the upper end of connecting rod 3 is connected with crosshead 2.At the both sides (left and right in Fig. 1) of crosshead 2, the pair of sliding plate 6 vertically extended to be fixed on the state of frame 5 side to be provided with.
As in figure 2 it is shown, sliding panel 6 is fixed on the next door 9 of frame 5.That is, the i.e. fixing end 6a of a side of sliding panel 6 is fixed on next door 9, and sliding panel 6 sets for thirty years of age towards another side.It addition, another side is the free end 6b not being fixed on next door 9.
The strengthening parts such as sliding panel 6 is simply fixed on next door 9 by fixing end 6a, the rib being not provided with preventing sliding panel 6 from deforming.
Crosshead 2 has: the lower end of piston rod 24 and the upper end of connecting rod 3 connect into rotating pin 14；Carry out sliding and reciprocating crawler shoe (sliding part) 8 relative to sliding panel 6；And the connecting plate (connecting portion) 13 of connecting pin 14 and crawler shoe 8.
Fig. 3 represents the side view of the crosshead 2 in terms of the end face side of pin 14.As shown in the drawing, crawler shoe 8 is provided with a pair in pin 14 both sides.It is provided with arm 13a in crawler shoe 8 side of connecting plate 13.As shown in Figure 4, this arm 13a connects crawler shoe 8 and the main part 13b of connecting plate 13.The side force carrying out self-marketing 14 passes to sliding panel 6 through this arm 13a.It addition, as shown in the drawing, crawler shoe 8 only connects and has arm 13a, in addition to arm 13a, be not provided with transmitting the force to the parts of crawler shoe.
As shown in Figure 4, arm 13a deviates to the axis direction center side (left side in this figure) of pin 14 from the central part (central part of left and right directions in this figure) on the axis direction of pin 14 of crawler shoe 8.More specifically, the central axial line C1 of arm 13a deviates with bias d0 to the axis direction center side of pin 14 from the central axial line C2 of crawler shoe 8.Therefore, pass to the application point P of the side force of crawler shoe 8 through arm 13a from pin 14 be located in the central axial line C1 of the arm 13a deviateed from the central axial line C2 of crawler shoe 8.Therefore, when side force is applied on application point P, around application point P, just produce the moment counterclockwise in Fig. 4, the medial end 8b of crawler shoe 8 conjugates to sliding panel 6 side (lower section in Fig. 4), and outboard end 8a of crawler shoe 8 conjugates to the axis side (top in Fig. 4) of pin 14.
Additionally, by making the central authorities of application point P deviation crawler shoe 8, thus it is positioned at the outboard end (end of the side, side of sliding part) of the crawler shoe 8 of the fixing end 6a side of sliding panel 6 distance d1 between 8a and application point P and is greater than being positioned at the medial end (end of the opposite side side of sliding part) of crawler shoe 8 of free end 6b side of sliding panel 6 distance d2 between 8b and application point P.Thus, when side force puts on application point P, the displacement of outboard end 8a is greater than the displacement (with reference to Fig. 5 (b) described later) of medial end 8b.
On the other hand, as it is shown on figure 3, on the upper end 8c and bottom 8d of the vibration-direction (above-below direction in this figure) of crawler shoe 8, be provided with thinner wall section 8f that thickness is thinner than the central part 8e of the above-below direction of crawler shoe 8.This thinner wall section 8f is formed as the taper that the outer contour 13b with arm 13a is connected when crosshead 2 is seen in side as shown in Figure 3.That is, thinner wall section 8f is formed by the face of the side contrary with sliding panel 6 is removed into taper.Fig. 6 (b) is the diagram that the end of crawler shoe 8 gives enlarged representation, and knowable to this figure, the outer contour 13b of arm 13a is formed continuously with the tapering 8g of thinner wall section 8f.This shape is formed preferably along from arm 13a towards the line of tension of the side force of crawler shoe 8.It addition, the shape of comparative example is represented by dashed line in this figure.This compares shape is commonly used shape, and the end thickness of crawler shoe 8 is identical with central part, and, arm 13a ' was the width identical with crawler shoe 8 before its outer contour 13b ' is connected with crawler shoe 8.That is, the shape of comparative example is that the end of crawler shoe 8 has the rigid shape bigger than present embodiment.
Then, side force the deformation of the sliding panel 6 caused is described with Fig. 7 and Fig. 8.
Fig. 7 represents the change of the side force corresponding with the position of crosshead 2, and in the figure, transverse axis represents the size of the side force being applied on sliding panel by crosshead 2, and the longitudinal axis represents the vibration-direction position of crosshead 2.As shown in the drawing, represent that side force is maximum at position Z1 and position Z2.This is because, position Z1 represents that side force increases because of the blast of the combustion space in cylinder, and position Z2 represents that piston rod 24 (with reference to Fig. 1) tilts from vertical and makes the component in the direction (lateral) towards sliding panel 6 become big.So, the size of side force changes with the vibration-direction position of crosshead 2.
Fig. 8 represents two kinds of deformation patterns by the sliding panel 6 during side force.
Deformation pattern A is the pattern that the free end 6b of sliding panel 6 is carried out deflection deformation by side force with fixing end 6a for fulcrum.
Deformation pattern B is the pattern that crawler shoe 8 locally pushing sliding panel 6, sliding panel 6 locally produce recessed deformation.
Below, deformation pattern A and deformation pattern B it are respectively directed to so that the action effect of present embodiment to be described.
[deformation pattern A]
For deformation pattern A, the deviation of the application point P shown in the crosshead 2 of present embodiment, Fig. 4 plays a role effectively.
That is, as shown in Fig. 5 (a), when side force is applied to left from right in the figure, the free end 6b of sliding panel 6 is as displacement (deformation pattern A) to the left as shown in double dot dash line.
On the other hand, due to present embodiment crosshead 2 arm 13a to free end 6b lateral deviation from, therefore application point P from the central axial line C2 of crawler shoe 8 to free end 6b lateral deviation from.Thus, clockwise moment is applied on crawler shoe 8, as shown in Fig. 5 (b), outboard end 8a of crawler shoe 8 can be made to conjugate significantly to pin 14 side (right side in figure).Owing to the deformation of this crawler shoe 8 is the deformation as deformation pattern A of sliding panel 6, therefore make the deformation of crawler shoe 8 and then sliding panel 6 and deform, the face drops between sliding panel 6 and crawler shoe 8 can be made.
So, use present embodiment, owing to the deformation of deformation pattern A of sliding panel 6 can be allowed and makes face drops, therefore this strengthening measure of strengthening part of the rib etc. that need not increase the thickness of slab of oscillating deck 6 or increase other.Therefore, as in figure 2 it is shown, the structure cancelled by the rib of the free end 6b deformation of suppression sliding panel 6 can be used.Then, lightweight and the cost that can obtain crosshead type diesel engine decline.Additionally, due to the operation being welded on by reinforcement rib on sliding panel 6 and next door 9 (with reference to Fig. 2) can be omitted, therefore manufacturing time and manufacturing cost can be greatly reduced.
[deformation pattern B]
For deformation pattern B, thinner wall section 8f shown in the crosshead 2 of present embodiment, Fig. 3 plays a role effectively.
That is, as shown in Fig. 6 (b), owing to being provided with thinner wall section 8f at end 8c, 8d of crawler shoe 8, therefore the rigidity of this thinner wall section 8f is less than the central part 8e of crawler shoe 8.Thus, can reduce and be delivered to the side force of sliding panel 6 by end 8c, 8d of crawler shoe 8.Accordingly, it is capable to the local avoiding the face of crawler shoe 8 end to press increases.Such as, when as the comparative example shown in dotted line, make a timing by identical with central part for the thickness of the end of crawler shoe 8, the side force transmitted through the end of crawler shoe 8 as the dotted line of Fig. 6 (a) as shown in, expression maximum.On the contrary, in the present embodiment, shown in solid such as Fig. 6 (a), owing to the rigidity making end 8c, 8d is lower than central part 8e, therefore the face pressure of end 8c, 8d of crawler shoe 8 can be made the most certain identically with central part 8e.
So, use present embodiment, owing to the deformation of deformation pattern B of sliding panel 6 can be allowed and makes the face drops of crawler shoe end 8c, 8d and homogenization, therefore the thickness of slab that need not to increase oscillating deck 6 or this strengthening measure of strengthening part of the rib etc. that increases other.Therefore, as in figure 2 it is shown, the structure cancelled by the rib of the free end 6b deformation of suppression sliding panel 6 can be used.Then, lightweight and the cost that can obtain crosshead type diesel engine decline.Additionally, due to the operation being welded on by reinforcement rib on sliding panel 6 and next door 9 (with reference to Fig. 2) can be omitted, therefore manufacturing time and manufacturing cost can be greatly reduced.
Further, since the face making the side contrary with sliding panel 6 be removed after thinner wall section 8f of shape, therefore can easily be processed.Additionally, due to do not reduce relative to sliding panel 6 slide area form thinner wall section 8f, therefore face pressure can not be made to form thinner wall section 8f with increasing.
Below, modified embodiment of the present embodiment is described.
The deviation method of the application point P shown in Fig. 4 can be replaced to use the deviation method shown in Fig. 9.I.e., although at the base end part 30a of the arm 30 shown in Fig. 9, the central axial line of arm 30 is consistent with the central axial line C2 of crawler shoe 8, but is formed with notch part 31 in crawler shoe 8 side of base end part 30a.This notch part 31 is located at the fixing end 6a side (i.e. the outboard end 8a side of crawler shoe 8, the upside in this figure) of sliding panel 6, and is formed towards the free end 6b side (i.e. the medial end 8b of crawler shoe 8, the downside in this figure) of sliding panel 6.So, by arranging notch part 31, it is thus possible to make application point P to the medial end 8b lateral deviation of crawler shoe 8 from, it is allowed to the deformation of notch part 31.
Additionally, due to notch part 31 is in R shape, therefore can concentrate by relaxing stress and avoid repeating the life-span decline that load is brought.
Though it addition, make the central axis of the base end part 30a of the arm 30 shown in Fig. 9 consistent with the central axial line C2 of crawler shoe 8, also can make the central axis of base end part 30a to the medial end 8b lateral deviation of crawler shoe 8 from.
It addition, about thinner wall section 8f shown in Fig. 3, although making the face tapered (with reference to Figure 10 (a)) of the arm 13a side of crawler shoe 8, but also can replace, as shown in Figure 10 (b), the face making the arm 13a side of crawler shoe 8 is rectangular.It addition, as shown in Figure 10 (c), it is possible to the face making the arm 13a side of crawler shoe 8 is R shape.
It addition, as shown in Figure 10 (d), it is possible to make the face of sliding panel 6 side of crawler shoe 8 end leave sliding panel 6 ground and be formed as taper, thinner wall section 8f is thus set.
In addition, the shape of sliding panel 6 side of thinner wall section 8f shown in Figure 10 (d), it is possible to the combination of shapes shown in Figure 10 (a) to (c) after being processed with the face (face of arm 13a side) of the opposition side to sliding panel 6.
