Background technique:
Along with fast development of national economy, diesel generating set require supporting power, power is increasing, reliability is more and more higher, existing cylinder diameter is the V-type diesel that 135～138mm adopts the tunnel type crankcase machine body, though through design improvement repeatedly, the output power of diesel engine is constantly promoted, the structure of its body is still more outmoded, intensity and toughness is also relatively poor, the piston stroke of diesel engine reaches present 158mm and has arrived the limit, and the reliability of strengthening type can not be satisfactory.It is bigger to develop output power for this reason, the new architecture of better reliability, at first just must design a kind of body of novel V-type family machine, make it not only can adapt to the diesel engine discharge capacity and further increase, stiffness and strength also increases substantially and can satisfy the requirement of developing V-type 16 cylinder machines.
Summary of the invention:
The purpose of this utility model is to provide a kind of can adapt to cylinder diameter 135～142mmV type serial diesel engine tunnel type crankcase machine body that cylinder diameter is 135～142mm, piston stroke is long, output power is big.
Technical solution of the present utility model is:
A kind of cylinder diameter 135～142mmV type serial diesel engine tunnel type crankcase machine body comprises bearing support, cooling jacket, the cylinder block of main bearing hole, camshaft, and it is characterized in that: the main bearing hole diameter is equal to or greater than 280mm; The bearing support of camshaft is axially being setovered to its supporting plate.
Adopt circular cooling jacket, total water channel leads to the upper angled of the diversion channel of each cylinder to cylinder-bore;
The two side of crankcase is a broken line type.
On the outer side surface of both sides cylinder block, be equipped with crossed reinforced muscle in length and breadth; On the inner side surface of the both sides of V-arrangement angle, also be provided with the stiffening rib that intersects vertically.
The secondary oil duct that connects before and after crankcase inboard below the V-arrangement angle is provided with, the working surface of oil spout cooling piston nozzle is installed on the secondary oil duct, protrude the non-working surface of its periphery, the filler opening of secondary oil duct is at the front end of body, connects with oil duct on the driving mechanism cover plate.
The diaphragm of main bearing seat top is a circular arc being in the cylinder-bore position, and the local reduction district that dodges cylinder liner and piston on the main bearing seat periphery also is circular arc.
The screw of cylinder head bolts " lug " extends downwardly into the middle part near water jacket, and the two bottom sides of each " lug " is equipped with stiffening rib.
The oil road of oil pump is being equipped with outlet on two sides about body.
The utility model novel and reasonable structure, can adapt to cylinder diameter is 135～142mm, piston stroke is long, output power is big, bearing capacity is strong, the various V-type machines that can adapt to multiple cylinder diameter, multiple stroke and difference cylinder number use, existing good technology inheritance, can satisfy series product development again, for the V-type machine development of new high-output power is laid a good foundation.
