Specific embodiment
Fig. 1 illustrates the big turbocharging two-stroke internal combustion engine 1 of crosshead, including the He of lubricant source 2 of lubricant fluid body
Connecting rod 3.Connecting rod 3 includes first end 4, the second end 7, and first end 4 has and is configured to be connected to the first hole 5 of crosshead 6, second
End 7 has the second hole 8 for being configured to connect to crank-pin 9.Connecting rod 3 also includes the bar portion being located between the end 7 of first end 4 and second
10.Connecting rod 3 includes the 3rd hole 12 being arranged in bar portion 10, and the 3rd hole 12 is than mid portion 13 (shown in Fig. 2) closer to it
In a bearing, the 3rd hole is configured to change rigidity of the connecting rod 3 on axially extending line L (shown in Fig. 2).
By arranging the 3rd hole 12, the hardness or rigidity of connecting rod 3 diminish, and connecting rod 3 is applied to the power point on crank-pin 9
In the contact surface in the second bigger in than there is no the prior art of the connecting rod in the 3rd hole in disclosure hole 8 of cloth, it is possible thereby to
Connecting rod 3 is made to significantly thinner and is made to may be significantly smaller by the first and second holes 5,8, thus can also be by the He of crank-pin 9
Bearing mnanufacture in crosshead 6 obtains less, and does not reduce bearing performance.By the thickness t (shown in Fig. 2) for reducing connecting rod 3, crank
Axle 35 (shown in Fig. 1) can also be made considerably shorter, be substantially reduced the total length of engine, and in the kinematics of engine
Positive effect is produced in unbalance and vibration.Therefore, it is goods by using the 3rd hole 12, significantly reducing the cumulative volume of engine
Thing vacates bigger space.In addition, the size and the thus size of generator by reducing connecting rod 3, also substantially reduces and sends out
The gross weight of motivation, this causes to reduce the gross weight of ship and the cost related to transport so load.
When power is transmitted from a part to another part, it is extremely difficult to obtain enough lubricating oil, because passing in energy
The power for passing middle applying forces lubricating oil to leave power transmission point.Especially when power is transmitted between connecting rod and crank-pin, big power
The lubricant fluid of compressing such as lubricating oil leaves transmission point, and the more lubricants of hardly possible injection during transmitting.
When the size of crank pin bearing and cross head bearing is determined for big two stroke diesel engine, optimum oil film pressure, bearing clearance,
Stress and tension force in oil film thickness and bearing is considered main standard.Therefore, it is possible to connecting rod and crank-pin/crosshead it
Between bearing supply lubricant fluid and thus reduce the stress in these junctions to obtain optimal oil film thickness and oil film
Pressure is critically important.
When pressure distribution over a larger area when, oil film, i.e. lubricant fluid are easier to be applied to connecting rod and crank-pin
Between junction on, and lubricant fluid is similarly distributed within high surface area, makes the lube layer in the second hole 8 equal
It is even.
