Technical field
The invention belongs to technical field of engines, specifically, the particularly air-cooled crankcase body radiating structure of a kind of single cylinder diesel.
Background technique
At present, the crankcase body of small single-cylinder air cooling diesel engine is generally distributed with radiating fin in the periphery of cylinder block, is taken away the heat in cylinder block by air-cooled mode.Because radiating fin concentrates in cylinder block, and the wall of cylinder block is thicker, the less effective of heat radiation, and the cylinder temperature on diesel engine is still higher, easily affects reliability and the stability of diesel engine, diesel engine is often broken down.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of air-cooled crankcase body radiating structure of single cylinder diesel that effectively can reduce cylinder temperature.
Technological scheme of the present invention is as follows: the air-cooled crankcase body radiating structure of a kind of single cylinder diesel, comprise casting all-in-one-piece crankcase body (1) and cylinder block (2), crankcase body (1) is provided with starting electrical machinery mounting hole (3), Curved shaft support hole (4) and camshaft mounting hole (5), Curved shaft support hole (4) is positioned between starting electrical machinery mounting hole (3) and camshaft mounting hole (5), its key is: described starting electrical machinery mounting hole (3), the line of centres of Curved shaft support hole (4) and camshaft mounting hole (5) three is generally within straight line, the first cooling duct (6) through before and after the epicoele wall of described crankcase body (1) die cavity offers, the root of this first cooling duct (6) adjacent cylinder block (2), and the cross section of the first cooling duct (6) is the elongated rectangular shape of lateral arrangement, the radiating fin (7) that a row is parallel to each other is provided with in the bottom of described crankcase body (1), top and the crankcase body (1) of this radiating fin (7) are connected as a single entity, be provided with one at the top of described cylinder block (2) along its true dip direction and ranked second cooling duct (8), distance between two adjacent second cooling ducts (8) is equal, the cross section of described second cooling duct (8) is also elongated rectangular shape, the length direction of this elongated rectangular shape is vertical with the shaft axis of cylinder block (2), the 3rd cooling duct (9) through before and after offering in the angle region that the bottom of described cylinder block (2) and crankcase body (1) are formed, 3rd cooling duct (9) is triangle.
Above structure is conducive to starting electrical machinery, bent axle and cam shaft arrangement, each several part is assembled simpler, convenient.First cooling duct of crankcase body die cavity epicoele wall is used for ventilation and heat, to take away the heat at crankcase body top; Row's radiating fin bottom crankcase body also can play the effect of wind-cooling heat dissipating, to take away the heat bottom crankcase body; Cylinder block has in periphery the basis of radiating fin sets up one ranked second cooling duct, and this second cooling duct is used for ventilation and heat, and the radiating fin that the second cooling duct and cylinder block carry combines, and can distribute the heat in cylinder block as much as possible; Offer the 3rd cooling duct in the angle region formed with crankcase body bottom cylinder block, the 3rd cooling duct is used for ventilation and heat, to take away the heat in crankcase body and cylinder block.The present invention can effectively reduce the heat load of diesel engine, and make the cylinder temperature of diesel engine lower, the reliability of such diesel engine and good stability, rate of fault is few.The cross section of the first cooling duct is the elongated rectangular shape of lateral arrangement, and ventilation is large on the one hand, and radiating effect is remarkable; On the other hand, the ingenious thickness that make use of crankcase body die cavity epicoele wall can be shaped, and processing and fabricating is easy, and can not destroy the structural strength of this part of crankcase body.Second cooling duct is arranged in a row, and its cross section is also elongated rectangular shape, and the point that ventilates is many, and ventilation is large, and radiating effect is remarkable equally.3rd cooling duct is triangle, the ingenious clear position that make use of angle between crankcase body and cylinder block, and ventilated is good, and can play the effect of loss of weight.
As preferably, have angle theta between the horizontal axis of described Curved shaft support hole (4) and the shaft axis of cylinder block (2), this angle theta is 25-30 °.
Beneficial effect: the present invention by setting up cooling duct on crankcase body and cylinder block, can effectively reduce cylinder of diesel engine temperature, diesel engine is operated reliable, good stability, rate of fault is few, there is the features such as design is ingenious, structure simple, transformation is easy, reforming cost is low, all applicable on the diesel engine of various model.
