Part or other component parts.
As shown in Figure 1,10 cylinder diesel crankshaft of V-type according to the preferred embodiment of the invention specifically includes: trunnion 11,
Rod journal 12, crank arm 13 and balance weight.Wherein, trunnion 11 is installed on cylinder body, rod journal 12 and big end
Hole connection, connecting rod small end hole are connect with steam-cylinder piston, and trunnion 11 and rod journal 12 are connect with the two sides of crank arm 13 respectively,
One trunnion, 11, rod journals 12 and a crank arm 13 constitute a crank throw.The 10 cylinder diesel crankshaft of V-type tool
It is equipped with suitable firing order, can be effectively reduced crankshaft by the design to five crank throw major parameters there are five crank throw
Torsional oscillation performance, and crankshaft strength and Lubrication Film Thickness are improved, so that crankshaft of diesel engine is able to bear higher explosion pressure.
Specifically, engine crankshaft is the main rotary gadget of engine, after loading onto connecting rod, can accept the upper and lower of connecting rod
(reciprocal) movement becomes to recycle (rotation) movement, is an important parts on engine.The rotation of crankshaft is engine
Power source.It is also the driving source of entire mechanical system.
Trunnion 11 is hollow structure, i.e. the center of trunnion 11 offers the first axially extending lightening hole, it is preferred that
First lightening hole is cylindric.The centre of first lightening hole is provided with ribs.
Rod journal 12 is hollow structure, i.e., the second lightening hole is offered in rod journal, and second lightening hole is through company
The left and right sides end face of bar axle journal, it is preferred that second lightening hole is arc.
One end of trunnion 11 and one end of rod journal 12 connect with the two sides of crank arm 13 constitute crank throw respectively.
The centrifugal force and torque that balance weight is generated for balance crankshaft rod journal and crank arm, make crankshaft operation steadily and
The load that trunnion bearing shell is born is reduced, so that engine steadily operates, reduces trunnion load.There are two types of balance weights, a kind of
It is that one is made with crankshaft;Another kind is formed into individually, then is screwed on crank.Latter is called assembled balance
Block, engine generally use the balance weight of integral type.
(1) main design parameters of crank throw:
As shown in Fig. 2, the diameter d1/D (cylinder diameter) of trunnion is 0.91~1.1, crankshaft strength can be effectively improved.
