Abstract
A flywheel for a single-cylinder air-cooled diesel engine comprises an inertia wheel, fan blades and a connecting wheel, wherein the outer diameters D1 of the inertia wheel and the connecting wheel are 280 mm, the inner diameters D2 of the inertia wheel and the connecting wheel are 210 mm, 20-30 fan blades are uniformly arranged between the inertia wheel and the connecting wheel, the outer ends of the fan blades are distributed on the circumference with the radius R1 of 139.5 mm, the inner ends of the fan blades are distributed on the circumference with the radius R3 of 106 mm, the cross section of the fan blades is an annular belt with the radius R4 of 43 mm circular arc, the circle center of the circular arc is distributed on the circumference with the radius R2 of 135 mm, and the thickness of the circular arc; because the number of the fan blades is increased from 15 to 20-30, the air volume generated by the flywheel is in direct proportion to the number of the fan blades under the condition of the same rotating speed, when the number of the fan blades is more than 30, the air volume generated by the flywheel is the largest, and when the number of the fan blades is 30 under the condition of the same output rotating speed, output power and working time, the machine temperature of the diesel engine is the lowest.
Description
Technical field:
The present invention relates to a kind of small-sized single cylinder air-cooled diesel engine component, relate in particular to the flywheel that 170F type single-cylinder air-cooled diesel engine is used.
Background technique:
On small air-cooled diesel engine, flywheel is one of key components and parts extremely, it be the flying wheel of diesel engine motion be again the cooling fan of whole diesel engine, in the working procedure of diesel engine, flywheel structure is very big to the cooling effect influence of diesel engine.The used flywheel of 170F type single-cylinder air-cooled diesel engine includes flying wheel at present, fan blade and connecting wheel, between flying wheel and connecting wheel, be distributed with 15 fan blade equably, the sectional shape of fan blade is the endless belt of circular arc, through the examination cls analysis, under the same rotational speed condition, the distributing position of fan blade and structure shape are very big to the influence of cooling air quantity, the present used flywheel of 170F type single-cylinder air-cooled diesel engine, the distributing position of its fan blade and structure shape design are unreasonable, can not make diesel engine reach comparatively desirable cooling effect by 15 air quantity that fan blade produced, the machine temperature is too high in actual use for diesel engine, the output power instability of diesel engine, the working life of diesel engine is not long.
Summary of the invention:
Goal of the invention of the present invention is: the flywheel that provides a kind of single-cylinder air-cooled diesel engine to use.
The flywheel that described single-cylinder air-cooled diesel engine is used, comprise flying wheel, fan blade and connecting wheel, fan blade is evenly distributed between flying wheel and the connecting wheel, flying wheel has spoke, it is characterized in that: the outer diameter D 1 of flying wheel and connecting wheel is 280 millimeters, inside diameter D 2 equal 210 millimeters, between flying wheel and connecting wheel, be provided with 20～30 fan blade equably, it is on 138.5～140 millimeters the circumference that the outer end of fan blade is distributed in radius R 1, it is on 105～106.5 millimeters the circumference that the inner of fan blade is distributed in radius R 3, the sectional shape of fan blade is that radius R 4 is the endless belt of 43 millimeters circular arcs, it is on 135 millimeters the circumference that the center of circle of fan blade circular arc is distributed in radius R 2, the thickness of fan blade≤4 millimeter.
As to of the present invention perfect, be provided with 30 fan blade between flying wheel and connecting wheel equably, the thickness of fan blade is 4 millimeters, and it is on 139.5 millimeters the circumference that the outer end of fan blade is distributed in radius R 1, it is on 106 millimeters the circumference that the inner of fan blade is distributed in radius R 3
Owing in existing flywheel, increased the quantity of fan blade, fan blade is increased to 20～30 by original 15, through test, the quantity of fan blade is between 20～30, under equal speed conditions, the air quantity that flywheel produced is directly proportional with the quantity of fan blade, when the quantity of fan blade during greater than 30, the air quantity that flywheel produces is constant substantially, under the identical condition of output speed, output power, operating time, when fan blade quantity was 30, the machine temperature of diesel engine was minimum.
