Background technique
As everyone knows, diesel-engine body is the important component part of diesel engine, it is the skeleton of diesel engine, by it, support and install other parts, therefore its soundness is had to higher requirement, in some current diesel engine, be provided with horizontal oil duct, the i.e. oil duct of cross setting in main bearing wall between two cylinder holes, at present, horizontal oil duct is generally arranged between a cylinder and two cylinder, the machine oil that filtering finishes arrives main oil gallery by horizontal oil duct, because horizontal oil duct is in the bottom of bolt of main bearing cap, be subject to the alternating stress that bolt is larger, cause horizontal oil duct drawing crack, therefore, need stiffening rib to reinforce, and current stiffening rib shape and unreasonable structure, stiffening rib is bar shaped, the area of contact of stiffening rib and horizontal oil duct is less, horizontal oil duct can be by drawing crack or frequent, cause leakage of oil, serious impact user's use.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of horizontal oil duct service-strong diesel-engine body is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of diesel-engine body, comprise some cylinders hole, wherein in the main bearing wall between two adjacent cylinder holes, be provided with horizontal oil duct, the both sides of described main bearing wall are respectively equipped with some stiffening ribs that connect described horizontal oil duct, described stiffening rib comprises a main muscle, one end of described main muscle is provided with muscle at least 2 times, and the both sides of main muscle bearing of trend are all no less than muscle 1 time, the end of described muscle is connected with described horizontal oil duct, the angle that any one muscle and main muscle form is greater than 145 degree, the both sides up and down of described horizontal oil duct are equipped with described stiffening rib.
Owing to having adopted technique scheme, by having changed shape and the structure of stiffening rib, both sides up and down at horizontal oil duct are all provided with stiffening rib, and some the muscle by stiffening rib are connected with horizontal oil duct, and the both sides of main muscle are all no less than 1 time muscle, any one muscle is greater than 145 degree with the angle of main muscle formation, stress can be disperseed thus, can guarantee that the power being subject on every muscle is all little than main muscle, thereby prevent that horizontal oil duct is by drawing crack.
Preferred as one, the main muscle that is positioned at the described stiffening rib of described horizontal oil duct below is connected on the bolt of main bearing cap reinforcing boss of described body, the main muscle that is positioned at the described stiffening rib of described horizontal oil duct top is connected in the water cavity bottom of described body, main muscle is connected to above-mentioned position, it is more firm to guarantee to connect, and uses more reliable.
Preferred as one, the stiffening rib of the both sides of described main bearing wall is symmetrical arranged, and every side is equipped with 4 stiffening ribs, 4 described stiffening ribs that are positioned at main bearing wall the same side wherein 2 be positioned at described horizontal oil duct top, other 2 are positioned at described horizontal oil duct below, described stiffening rib is all installed on the position near described horizontal oil duct end, horizontal oil duct is comparatively fragile in the position near end, easily drawing crack, by being all provided with 4 in each side of main bearing wall, the end that guarantees horizontal oil duct all has stiffening rib to reinforce up and down, thereby can be with less stiffening rib, play best consolidation effect, this is also easy in the manufacture of body casting mold.
Preferred as one, the main muscle of described stiffening rib is provided with muscle 2 times, and the angle between described twice muscle is less than 90 degree, whole stiffening rib is Y type, by using the stiffening rib of Y type, is guaranteeing under the prerequisite of consolidation effect, can simplify the structure of stiffening rib as far as possible, be convenient to manufacture.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 2 is the structural representation of the stiffening rib of the utility model diesel-engine body;
In figure: 1, main bearing wall; 2, horizontal oil duct; 3, stiffening rib; 31, main muscle; 32, inferior muscle; 4, bolt of main bearing cap is reinforced boss;
Embodiment
As depicted in figs. 1 and 2, a kind of diesel-engine body, comprise some cylinders hole, wherein in the main bearing wall 1 between two adjacent cylinder holes, be provided with horizontal oil duct 2, current diesel-engine body, conventionally as shown in Figure 1, horizontal oil duct 2 be arranged between a cylinder and two cylinder main bearing wall 1 on, the both sides of described main bearing wall 1 are respectively equipped with the some stiffening ribs 3 that connect described horizontal oil duct 2, described stiffening rib 3 comprises a main muscle 31, one end of described main muscle 31 is provided with muscle 32 at least 2 times, and the both sides of main muscle 31 bearing of trends are all no less than muscle 32 1 time, the end of described muscle 32 is connected with described horizontal oil duct 2, any one muscle 32 is greater than 145 degree with the angle that main muscle 31 forms, as preferred version, as shown in Figure 2, the main muscle 31 of described stiffening rib 3 is provided with muscle 32 2 times, angle between described twice muscle 32 is less than 90 degree, whole stiffening rib 3 is Y type, guaranteeing under the prerequisite of consolidation effect, can simplify the structure of stiffening rib 3 as far as possible, be convenient to manufacture, from mechanics principle, 2 times muscle 32 equates with the power on main muscle 31 with joint efforts, 2 times muscle 32 is under acute angle state, the size of the component of every muscle 32 is less than the size of the suffered power of main muscle 31, the stress that can make oil duct be subject to thus reduces, improve the reliability of using.Certainly, the quantity of the inferior muscle 32 of stiffening rib 3 can be more, but, on manufacturing, can bother, but effect can be better on dispersive stress.The both sides up and down of described horizontal oil duct 2 are equipped with the stiffening rib 3 of said structure, the main muscle 31 that is positioned at the described stiffening rib 3 of described horizontal oil duct 2 belows is connected on the bolt of main bearing cap reinforcing boss 4 of described body, the main muscle 31 that is positioned at the described stiffening rib 3 of described horizontal oil duct 2 tops is connected in the water cavity bottom of described body, like this, the main muscle 31 that is positioned at the stiffening rib 3 of horizontal oil duct both sides Shang Xia 2 is all connected to the thicker position of main bearing wall 1 wall thickness, it is more firm to connect, the stiffening rib 3 of the both sides of described main bearing wall 1 is symmetrical arranged, and every side is equipped with 4 stiffening ribs 3, 4 described stiffening ribs 3 that are positioned at main bearing wall 1 the same side wherein 2 be positioned at described horizontal oil duct 2 tops, other 2 are positioned at described horizontal oil duct 2 belows, described stiffening rib 3 is all installed on the position near described horizontal oil duct 2 ends, due near the easiest drawing crack end of horizontal oil duct 2, can make so horizontal oil duct 2 ends obtain fine protection, thereby make horizontal oil duct 2 entirety all very firm.
