Abstract
The utility model relates to a reinforced multicylinder diesel engine body. Water jackets on an upper part of the engine body are circular hole shaped, Water pores on an end face of the engine boy are arranged on the top of the water jackets, stepped shoulder reinforcing bars are positioned outside a pore wall of a stub shaft of the engine body on all water jackets, the reinforcing bars are disposed between a bottom of a bolthole buckle of the cylinder cover on the upper part of the engine body and the bottom of a bearing bolthole buckle below and the depth of counterbores of all boltholes of the cylinder cover is between 25mm to 35mm. The utility model intensifies key parts of the engine body, so as to reduce the deformation stress at connections of the engine body, promote the rigidity of the engine body. The deformation of the cylinder sleeve is small and the air leakage is reduced, so that the quality of the stability of the diesel engine is ensured.
Description
Technical field
The utility model relates to a kind of multi-cylinder diesel engine body, relates in particular to a kind of reinforced multi-cylinder diesel engine body.
Background technique
Diesel-engine body occupies extremely crucial position in parts and components of diesel engine, all work systems all are installed on the body, the rigidity of body and intensity not only directly influence life-span, the sealing between each assembly and the distortion of component of component, and strength of machine body also is directly connected to the working life of diesel engine, and involves the problem that component and complete machine lost efficacy.Present disclosed multi-cylinder diesel engine body as shown in Figure 1, body significant points such as water jacket 1 part are basket shape, the stiffening rib 2 at water jacket position is positioned at its inboard, water hole 3 is not arranged on the end face of body, especially the counterbore in cylinder head bolt hole is usually at 8～10mm, therefore after bolt cylinder is installed on the body, can cause the stressed of body upper, easily cause the cylinder gasket that is installed between body and the cylinder head to damage, not only can lose sealing effect and serious gas leakage, and, also can cause the distortion of cylinder liner because of the local strength and the rigidity of body are not enough.
Summary of the invention
The purpose of this utility model provides a kind of key position to body and improves reinforcement, can make the body more reasonable stress, improves the reinforced multi-cylinder diesel engine body of body rigidity.
The utility model is that the technological scheme that solves the problems of the technologies described above is: a kind of reinforced multi-cylinder diesel engine body, it is characterized in that: the described water jacket that is positioned at body upper is a circular hole, the water hole of body end face is arranged on the top of water jacket, each water jacket is provided with the stiffening rib of stepped shaft convex shoulder in the hole wall outside of body minor axis, between the bottom of its bottom of the cylinder head screw lug of body upper and the bearing screw lug of its corresponding bottom, have stiffening rib, and the degree of depth of each its counterbore of cylinder head screw is between 25～35mm.
The utility model improves at original multi-cylinder diesel engine body, change the water jacket of body upper into circle hole shape, and the water hole is arranged on the end face of machine side, and each water jacket is provided with the stiffening rib of stepped shaft convex shoulder in the hole wall outside of body minor axis simultaneously, has improved strength of machine body and rigidity.The utility model can reduce the distortional stress of body joint owing to increased the cylinder head screw counterbore degree of depth, makes the cylinder head gasket sealing reliable, reduces gas leak phenomenon, and cylinder liner deformation is small, has guaranteed the diesel engine quality of stability.The utility model causes the more weak characteristics of body intensity at no stiffening rib between cylinder head bolt and the Main bearing bolt, increase stiffening rib in the bottom of cylinder head screw lug with the bottom of the bearing screw lug of its corresponding bottom, improved strength of machine body and rigidity.The utility model is owing to be optimized design to body, do not change on the basis of former porose system of body and processing technology in assurance, the architecture advances of carrying out by to the crucial force part of body makes the body more reasonable stress, and the Diesel Engine Complete Machine operational reliability is improved.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is former multi-cylinder diesel engine housing construction schematic representation.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the cross section sectional structure schematic views of Fig. 2.
Wherein: 1-water jacket, 2-stiffening rib, 3-water hole, 4-cylinder head screw, 5-cylinder head screw lug, 6-stiffening rib, 7-bearing hole screw lug.
Embodiment
See Fig. 2, reinforced multi-cylinder diesel engine body of the present utility model shown in 3, the water jacket 1 that is positioned at body upper is circular hole, the diameter of bore of this water jacket 1 is at 114～118mm, the water hole 3 of body end face is arranged on water jacket 1 top, water hole 3 communicates with water jacket 1 hole, water jacket 1 by circle hole shape is to improve strength of machine body, and each water jacket 1 is provided with the stiffening rib 2 of stepped shaft convex shoulder in the hole wall outside of body minor axis, between the bottom of its bottom of cylinder head screw lug 5 of body upper and the bearing screw lug 7 of its corresponding bottom, has stiffening rib 6, see shown in Figure 2, be provided with four cylinder head screws around each sleeve port, and corresponding bearing hole also is provided with four bearing screws, therefore be provided with four stiffening ribs 6 around each cylinder sleeve, this stiffening rib 6 is the rectangle stiffening rib, and the width of rectangle stiffening rib is at 15～20mm, and length can increase substantially the strength and stiffness at body cylinder sleeve position at 20～30mm.See shown in Figure 2, the utility model is arranged on the degree of depth that goes up all cylinder head screw 4 its counterbores of body between 25～35mm, owing to increased the degree of depth of counterbore, body end and cylinder cap joint stress have been reduced, make the cylinder head gasket sealing reliable, reduce gas leak phenomenon, guaranteed the diesel engine quality of stability.
