Abstract
The invention discloses a V-shaped diesel engine cylinder body for a ship. The V-shaped diesel engine cylinder body comprises a V-shaped part positioned at the upper part and a crankcase positioned at the lower part, wherein a transverse cylindrical oil cooler cavity is formed in the middle of a V angle of the V-shaped part; and the oil cooler cavtiy is paralllel to a main oil gallery of the V-shaped diesel engine cylinder body. As the oil cooler cavity is arranged in the middle of the V angle of the V-shaped part, the lubricating oil cooling effect is good and the V-shaped diesel engine cylinder body is compact in struture, reasonable in layout and beatiful in appearance; and in addition, a monoblock pump cavity is obliquely arranged at a certian angle with the vertical diretion, and the top surface of the monoblock pump cavity and the gas distribution part of a V-shaped diesel engine are not on the same plane, so that a designed cylinder cover does not need to be matched with the top surface of the monoblock pump cavity, thereby lowering the requirement of the process of manufacturing the cylinder cover.
Description
Technical field
The present invention relates to diesel engine arts, particularly a kind of Marine V Type cylinder of diesel engine.
Background technique
At present, traditional Marine V Type cylinder of diesel engine is the main body of motor, and each cylinder and crankcase are connected by it, is the support framework installing piston, bent axle and other part and accessories.Wherein, cylinder lines up two row, the angle γ < 180 ° of left and right two row cylinder centerline, and V-type engine, compared with straight engine, shortens body length and height, adds the rigidity of cylinder block, alleviate the weight of motor.
The machine oil cooler of Marine V Type diesel engine a kind ofly accelerates lubricating oil heat radiation and make it keep the device of lower temperature.Installing the object of this device, is cause lubrication to weaken in order to avoid oil temperature raises.In the hydroecium that machine oil cooler is arranged on water tank usually or in cooling water system, make the integral layout of Marine V Type diesel engine unreasonable, structure is not compact.
In addition, the distribution of traditional Marine V Type diesel engine and Injection Pump plane of arrangement are a face, cause cylinder cover structure will corresponding to design, technological requirement is high.
Summary of the invention
The technical problem that the present invention solves is to provide one and has machine oil cooler chamber, rationally distributed, the Marine V Type cylinder of diesel engine of compact structure.
For achieving the above object, according to the invention provides a kind of Marine V Type cylinder of diesel engine, comprising: superposed V-type portion and the crankcase being positioned at bottom; Be provided with horizontal cylindric machine oil cooler chamber in the middle of the V angle in V-type portion, machine oil cooler chamber is parallel with the main oil gallery of V-type diesel cylinder block.
Further, the bi-side in V-type portion are arranged at intervals with tappet room watch window and monomer pump chamber respectively, and monomer pump chamber is obliquely installed in vertical direction with several angle, and the distribution of end face and V-type diesel is not in same plane.
Further, the side opening of crankcase is provided with the crankcase watch window corresponding with tappet room watch window.
Further, the both sides, bottom surface of crankcase reserved dismounting adjustment screw respectively.
Further, the both sides of crankcase adopt the horizontal bolt that draws to strain the main bearing cap of described crankcase and diesel engine.
According to technological scheme of the present invention, because machine oil cooler chamber to be arranged in the middle of the V angle in V-type portion by this Marine V Type cylinder of diesel engine, make lubricating oil good cooling results, and compact structure, rationally distributed, appearance looks elegant.In addition, monomer pump chamber is obliquely installed in vertical direction with several angle, and the distribution of end face and V-type diesel not in one plane, makes the design of cylinder cover structure not need with the end face of monomer pump chamber adaptive, reduces the technological requirement manufacturing cylinder cap.

Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Referring to Fig. 1, this Marine V Type cylinder of diesel engine comprises: superposed V-type portion 1 and the crankcase 2 being positioned at bottom.Wherein, the upper plane in V-type portion 1 offers cylinder barrel 11 arranged side by side.Horizontal cylindric machine oil cooler chamber 12 is provided with in the middle of the V angle in V-type portion 1, for holding machine oil cooler, this machine oil cooler chamber 12 be arranged in parallel (as shown in Figure 2) with the main oil gallery 13 of V-type diesel cylinder block, front and back sealing station utilizes twice O RunddichtringO to seal, and guarantees that structure is reliable.This structure lubricating oil good cooling results, and structure is quite compact, appearance looks elegant.The bi-side in V-type portion 1 are respectively arranged with tappet room watch window 14 and monomer pump chamber 15, and tappet room watch window 14 is for installing and removing connecting rod and tappet; Monomer pump chamber 15 is for installing Injection Pump, be obliquely installed in vertical direction with several angle, make the distribution of end face and V-type diesel not in one plane, the design of cylinder cover structure does not need with the end face of monomer pump chamber 15 adaptive, reduces the technological requirement manufacturing cylinder cap; Monomer pump chamber 15 is corresponding with cylinder barrel 11 to be arranged, and a corresponding monomer pump chamber 15 of cylinder barrel 11, can ensure that each cylinder interior core is consistent like this, easily can realize increase and decrease cylinder number, reduce cylinder block die cost.Monomer pump chamber 15 is obliquely installed in vertical direction with several angle, this ensure that the cylinder cap of V-type machine and arranging machine, rocking arm are general, does not need to do any change.
The side opening of crankcase 2 is provided with the crankcase watch window 21 corresponding with tappet room watch window 14, for observing crankcase internal state; In addition, the cover plate of crankcase watch window 21 adopts pad to ensure sealing, and cover plate stays an interface can directly input lubricating oil to enter body.As shown in Figure 3, the both sides of crankcase 2 adopt the horizontal bolt 22 that draws to strain the main bearing cap 23 of crankcase 2 and diesel engine, and such structure enhances the rigidity of cylinder block, obvious to the noise reduction of motor.Horizontal drawing between bolt 22 and Main bearing bolt leaves gap to guarantee not interfere between two bolts.The bottom surface 24 of crankcase 2 is widened, and except installation oil sump, the width of increase can conveniently install keel and support; Meanwhile, as shown in Figure 4, both sides reserved several dismounting adjustment screw 25 respectively of bottom surface 24, easily can back down it with screw when pasting too tight to facilitate plate below.As shown in Figure 5, the skirt section 26 of crankcase 2 is obviously widened, if like this motor to increase series increase stroke directly can increase and cylinder block mould need not be changed, shorten the construction cycle, saved development cost.
Because machine oil cooler chamber to be arranged in the middle of the V angle in V-type portion by this Marine V Type cylinder of diesel engine, make lubricating oil good cooling results, and compact structure, rationally distributed, appearance looks elegant.In addition, monomer pump chamber is obliquely installed in vertical direction with several angle, and the distribution of end face and V-type diesel not in one plane, makes the design of cylinder cover structure not need with the end face of monomer pump chamber adaptive, reduces the technological requirement manufacturing cylinder cap.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
