Embodiment Construction
[0016] An air-cooled diesel engine flywheel with blades includes a flywheel main body, long blades, short blades, keyways, tapered holes and threaded holes; the outer diameter of the flywheel main body is 270 mm, and 24 air outlets are evenly distributed on the outer circumference. Connected with the engine system; 24 fan blades, 12 long blades and 12 short blades are evenly arranged in the middle part of the main body of the flywheel, which are staggered in turn to form the air inlet; the outer ends of the fan blades are distributed on a circumference of 265 mm in diameter , the inner end is distributed on a circle with a diameter of 111 mm, the cross-sectional shape is a circular arc with a radius of 43 mm, the center of the arc is distributed on a circle with a radius of 110 mm, and the thickness of the blade is ≤ 7 mm; the inner hole of the flywheel body It is a tapered hole for matching with the crankshaft, with a taper of 1:5. One side of the tapered hole is provided with...

The invention discloses a flywheel with blades for an air cooling diesel engine. The flywheel comprises a flywheel main body (1), long blades (2), short blades (3), a key groove (4), a conical hole (5) and threaded holes (6); 24 air outlets are uniformly distributed on the outer circumference of the flywheel main body (1), and are communicated with an engine system; the 12 long blades (2) and 12 short blades (3) are uniformly arranged at the middle part of the flywheel main body (1), and are staggered in sequence to form air inlets; an inner hole is the conical hole (5), and the key groove (4) is arranged at one side of the conical hole (5); the plurality of threaded holes (6) in central symmetry are uniformly distributed at the middle part; the flywheel is tightly pressed on a crank shaft through a nut and a gasket; the relative positions of the flywheel and the crank shaft can be determined by keys; a dustproof cover is tightly pressed on the flywheel through the nut and the gasket; and a gear ring is mounted on the flywheel in an interference fit manner. With the adoption of the flywheel with blades provided by the invention, a rotating speed can be stabilized, the noise is reduced, and the operation balance property of the diesel engine is improved. Furthermore, the flywheel has air exhaust and cooling functions of a fan; the service life of the diesel engine is prolonged; and the manufacturing cost of the diesel engine is reduced.
Description
technical field [0001] The invention belongs to a component of an internal combustion engine, in particular to an air-cooled diesel engine flywheel with blades. Background technique [0002] At present, the cooling of air-cooled diesel engines mainly relies on a dedicated cooling fan, which increases the weight and cost of the internal combustion engine. Some fans are fixed on the flywheel, but the structure is complex and the efficiency is low, which cannot meet the cooling requirements of diesel engines. SUMMARY OF THE INVENTION [0003] The invention aims to solve the problems of the air-cooled diesel engine fan, which is heavy in weight, high in cost, complicated in structure and low in efficiency, and cannot meet the cooling requirements of the diesel engine. [0004] Technical scheme of the present invention: [0005] An air-cooled diesel engine flywheel with blades includes a flywheel main body, long blades, short blades, keyways, tapered holes and threaded holes;...
