Description
Technical field
The utility model relates to crankcase body technical field, particularly relates to a kind of cylinder body oblique installing type crankcase body.
Background technique
Common single cylinder diesel engine crankcase structure generally has two kinds, and a kind of is center line and the horizontal plane of cylinder sleeve, is called vertical; Another kind is center line and the plane-parallel of cylinder sleeve, is called horizontal.But two kinds of equal Shortcomings of structure, its Heavy Weight, volume are comparatively large, and the height dimension of vertical casing is larger.
In order to make casing miniaturization, lightweight, usually adopt the wall thickness the intensity/demeanour and the cooling requirements that meet complete machine that alleviate casing.
But in a prior art situation, often go wrong when reducing the wall thickness of crankcase body, intensity, or/and rigidity reduces, vibration increases, can cause casing to ftracture.
Model utility content
The technical problems to be solved in the utility model is to provide that a kind of volume is little, intensity or the large cylinder body oblique installing type crankcase body of rigidity.
For solving the problem, the utility model provides a kind of cylinder body oblique installing type crankcase body, described cylinder body oblique installing type crankcase body comprises casing, cylinder body and cylinder sleeve, the lopsidedness of described casing is provided with cylinder body, described cylinder sleeve is located in described cylinder body, the shaft axis of described cylinder sleeve and horizontal plane have certain angle, the size of this angle is between 20 ° to 30 °, described casing is provided with crankshaft hole, the below of described crankshaft hole is provided with camshaft hole, the outer of described crankshaft hole is arranged with crankshaft hole seat, the surrounding of described crankshaft hole seat is provided with stiffening rib, the outer of described camshaft hole is arranged with camshaft hole seat, the surrounding of described camshaft hole seat is provided with stiffening rib, described cylinder body is provided with some radiating fin.
Further, described bottom half is provided with the integrated fixed base with casing, and described fixed base is provided with some crisscross stiffening ribs.
Further, the top of described casing is provided with fixing frame, and described fixing frame is provided with two fixed holes.
Further, described cylinder sleeve internal diameter is 69-71mm.
Further, the distance between the center of described crankshaft hole and the center of described camshaft hole is 60-62mm.
The utility model cylinder body oblique installing type crankcase body adopts and is obliquely installed cylinder body, makes its height reduction, and volume reduces; The surrounding being simultaneously provided with stiffening rib and camshaft hole seat in the surrounding of the crankshaft hole seat of casing is provided with stiffening rib, even if reduce rigidity or intensity that tank thickness also can guarantee casing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the utility model cylinder body oblique installing type crankcase body.
Fig. 2 is the worm's eye view of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 is the sectional view of A-A in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 4, the better embodiment of the utility model cylinder body oblique installing type crankcase body comprises casing 1, cylinder body 2 and cylinder sleeve 3, the lopsidedness of described casing 1 is provided with cylinder body 2, described cylinder sleeve 3 is located in described cylinder body 2, the shaft axis of described cylinder sleeve 3 and horizontal plane have certain angle β, the size of this angle β is 25 °, makes it reduce the height of crankcase body.Described casing 1 is provided with crankshaft hole 11, the below of described crankshaft hole 11 is provided with camshaft hole 12, the outer of described crankshaft hole 11 is arranged with crankshaft hole seat 111, the surrounding of described crankshaft hole seat 111 is provided with stiffening rib, the outer of described camshaft hole 12 is arranged with camshaft hole seat 121, the surrounding of described camshaft hole seat 121 is provided with stiffening rib, arranges its rigidity or intensity when stiffening rib can guarantee that the thickness of casing 1 reduces and does not reduce thereupon.Described cylinder body 2 is provided with some radiating fin, strengthens the heat dispersion of cylinder body 2.
Be provided with fixed base integrated with casing 1 bottom described casing 1, described fixed base is provided with some crisscross stiffening ribs 14, increases intensity or the rigidity of casing 1.
The top of described casing 1 is provided with fixing frame 13, and described fixing frame 13 is provided with two fixed holes, is convenient to casing 1 better to fix.
Described cylinder sleeve 3 internal diameter is 70mm, should be understood that, in other embodiments, the internal diameter of described cylinder sleeve 3 can also be 69mm, and the internal diameter of described cylinder sleeve 2 also can also be 71mm.
Distance a between the center of described crankshaft hole 11 and the center of described camshaft hole 12 is 61mm, in other embodiments, distance a between the center of described crankshaft hole 11 and the center of described camshaft hole 12 can also be 60mm, also can also be 62mm, optimal design makes the compact structure in casing 1, so guarantees that the volume of casing 1 is little.
The utility model cylinder body 2 oblique installing type crankcase body 1 adopts and is obliquely installed cylinder body 2, cylinder sleeve is located in cylinder body 2, the shaft axis of described cylinder sleeve 3 becomes 25 ° of angle β with horizontal plane, and camshaft hole 12 is located at the lower side of described crankshaft hole 11, the height dimension of such crankcase body obviously reduces, volume-diminished, weight saving simultaneously; The surrounding being simultaneously provided with stiffening rib and camshaft hole seat in the surrounding of the crankshaft hole seat of casing 1 is provided with stiffening rib, even if reduce rigidity or intensity that casing 1 thickness also can guarantee casing 1.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
