Abstract
The utility model relates to a single-cylinder water-cooled diesel splitting housing divided into a cylinder block and a crankcase. The cylinder block is provided with a water chamber with nozzle communicated with the nozzle below the cooling water tank chamber. A plurality of screw holes is disposed at the joint face of the crankcase and the cylinder block, and a plurality of through holes for connecting bolts is disposed on the cylinder block corresponding to the screw holes on the crankcase. After division of the single-cylinder water-cooled diesel housing into a cylinder block and a crankcase, the utility model has simple and reasonable structure, good heat dissipation, good casting and machining process, and low manufacturing cost.
Description
Affiliated technical field
The utility model relates to a kind of single-cylinder water cooled diesel engine split body.
Background technique
Single-cylinder water cooled diesel engine is a kind of series model that output is big, wide in variety in the little bore internal combustion engine system of China, purposes is wide, specialist manufacturers is many.The body of existing single-cylinder water cooled diesel engine is a monolithic construction, its complex structure, and casting and technology capability are poor.Along with the increase of market to the light power demand, because the geneogenous defective of integrated type body causes the cylinder block water cavity narrow and small, the water cavity rough surface, the cylinder body wall is thicker, so that cooling water inflow is less than normal, and flow of cooling water is poor, easily boil in the diesel engine work, heat load increases.
Summary of the invention
In order to overcome the above-mentioned deficiency of integrated type body, the utility model provides a kind of single-cylinder water cooled diesel engine split body, existing body is resolved into cylinder block and crankcase (containing gear chamber) two parts that cylinder liner is installed, it can not only strengthen the water cavity area, and the casting and the technology capability of body have been improved, heat dispersion greatly improves, and weight also alleviates to some extent.
The technological scheme that its technical problem that solves the utility model adopts is: the body of existing single-cylinder water cooled diesel engine is separated into cylinder block and the crankcase (containing gear chamber) that cylinder sleeve is installed, the original structure complexity, it is simpler that the body of casting and technology capability difference is separated into structure, casting and technology capability be cylinder block and two parts of crankcase preferably, the foundry goods appearance is more smooth, and wall thickness is more even, and yield rate is higher, weight saving, cost reduces.Keeping existing same type machine power, apparent size is constant substantially, under the general prerequisite of auxiliary equipment, other structure and size are optimized design, as increase the volume of cylinder block water cavity, and the mouth of a river area that is communicated with water tank case chamber on the intensifying cylinder body, cooling water flow is bigger, it is more unimpeded to flow, better heat-radiation effect.A plurality of screws are arranged on the junction plane of crankcase and cylinder block, have a plurality of on the cylinder block and the corresponding through hole that is used for Bolt Connection of crankcase.There is positioning spigot the connecting part that is preferably in cylinder block and crankcase or locating stud is arranged or existing positioning spigot also has locating stud, the position when guaranteeing to assemble.This split body has reached rapid heat dissipation after adopting abovementioned technology, and thermo-mechanical property is stable, weight saving, the purpose that manufacture cost reduces.The utility model such as part or all of employing aluminium alloy casting effect are better.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is that the master after the utility model cylinder block and the crankcase assembling cuts open figure.
Fig. 1. cylinder block, 2. crankcase, 3. water cavity, 4 cooling water tanks, 5. stud bolt, nut, packing ring, 6. cylinder cap.
Embodiment
The utility model is separated into independent cylinder block (1) and (2) two foundry goods of crankcase with the body of existing single-cylinder water cooled diesel engine, cylinder block (1) has water cavity (3), corresponding mouth of a river below cooling water tank case chamber, the mouth of a river of water cavity (3) is connected, after packing cylinder block (1) into, cylinder liner just formed an annular water chamber that removes the sealing of opening wide at the mouth of a river, during diesel engine work, water in this water cavity carries out heat exchange with the water convection current in the cooling water tank that is in its top, reaches the diesel engine cooling purpose.Owing to adopt the split body, casting and processing technology are improved, and water cavity (3) the casting inside and outside surfacing in back of cylinder block (1) is smooth, and the volume of cavity can also suitably strengthen, and the wall thickness of air cavity (1) is more reasonable, and thickness is more consistent.
The casting manufacturability of same crankcase (2) also is improved together, and everywhere structure and size are improved targetedly, and its structure is simpler, and weight also can reduce.
On the junction plane of crankcase (2) and cylinder block (1) a plurality of screws are arranged, a plurality of and the corresponding through hole of crankcase (2) screw are arranged on the cylinder block (1), to overlap the screw of through hole on crankcase (2) that stud bolt (5) passes cylinder cap (6), cylinder block (1) more in the assembling, the three will be fixedly connected.Every cover stud bolt is made up of stud bolt, packing ring, nut.Such split body weight is light, thermal diffusivity good, and cost is low.
Accurate for better guaranteeing cylinder block (1) crankcase (2) when assembling position, on the junction plane of cylinder block (1) and crankcase (2), there are positioning spigot or locating stud or both to have concurrently.
Claims (4)
1, a kind of single-cylinder water cooled diesel engine split body, it is characterized in that body is made up of cylinder block (1) and crankcase (2), water cavity (3) is arranged on the cylinder block (1), water cavity (3) has the mouth of a river under the case chamber of the mouth of a river and cooling water tank (4) to be connected, on the junction plane of crankcase (2) and cylinder block (1) a plurality of screws are arranged, the corresponding through hole that is used for Bolt Connection of screw on a plurality of and the crankcase (2) is arranged on the cylinder block (1).
2, single-cylinder water cooled diesel engine split body according to claim 1 is characterized in that on cylinder block (1) and crankcase (2) junction plane positioning spigot being arranged.
3, single-cylinder water cooled diesel engine split body according to claim 1 is characterized in that on the junction plane of cylinder block (1) and crankcase (2) locating stud being arranged.
4, single-cylinder water cooled diesel engine split body according to claim 1 is characterized in that existing positioning spigot has locating stud again on the junction plane of cylinder block (1) and crankcase (2).
