Description
Technical Field
The utility model relates to an air-cooled engine takes the starting gear of forced air cooling blade, specifically speaking is the structure that electric starting gear and forced air cooling blade unite two into one.
Background
At present, a starting gear and an air-cooled blade of an air-cooled engine are all split structures. Wherein, the starting gear is made of metal, and the air-cooled blade is made of plastic. The starting gear and the air cooling blade are respectively arranged on a crankshaft of the engine through a mechanical structure. Such a structure leads to an increase in the volume and weight of the engine, and increases the mounting process and the component cost.
Disclosure of Invention
The utility model discloses to the shortcoming that present air-cooled engine starting gear and forced air cooling blade are bulky, weight is big, aim at providing a starting gear and forced air cooling blade unites two into one's structure, satisfy the operation requirement of engine, light in weight simultaneously, it is small.
In order to achieve the purpose, the technical proposal adopted by the utility model comprises a starting gear meshed with a one-way gear when the engine is electrically started and a plurality of air-cooled blades for providing cooling airflow for the cylinder body; the roots of the air cooling blades are arranged on the end surface of one side of the starting gear; the end part of the air cooling blade faces the heat radiation body.
When the engine is electrically started, the engine is started by the starting gear; when the engine runs, the air cooling blade rotates along with the starting gear and conveys cooling air flow to the engine.
Wherein, the starting gear and the air-cooled blade are vertically connected.
Wherein, the air-cooled blades are uniformly distributed along the radius of the end surface of the starting gear.
Wherein, the starting gear and the air-cooled blade are integrally formed.
The starting gear and the air cooling blade are made of modified POM plastics, and the part is molded through injection molding.
The strength of the starting gear with the air cooling blades meets the electric starting requirement of the engine; the air-cooled blades meet the cooling requirements of the cylinder head and the cylinder body of the engine.
Compared with the prior art, the utility model has the advantages that the starting gear and the air cooling blade are combined into a whole, the volume of the engine is reduced on the premise of achieving the same technical effect, and the manufacturing cost is reduced; and the whole injection molding of the starting gear and the blades is finished, so that the weight of the whole body is reduced.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic view of the installation and use of the present invention;
referring to the attached drawings, 1, a starting gear and 2, an air cooling blade.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the structural schematic diagram of the present invention is shown, in which a starting gear 1 and an air-cooling blade 2 are combined into one, so as to satisfy two functions of electric starting and heat dissipation for an engine. Specifically, the starting gear 1 is meshed with the one-way gear when the engine is electrically started, and sixteen air-cooling blades 2 provide cooling air flow for the cylinder body; the root of the air-cooled blade 2 is arranged on the end surface of one side of the starting gear 1; the end part of the air cooling blade 2 faces the heat radiation body; the air-cooled blades 2 are circular arc-shaped.
When the engine is electrically started, the engine is started by the starting gear; when the engine runs, the air cooling blade rotates along with the starting gear and conveys cooling air flow to the engine.
Further, the starting gear 1 and the air-cooling blade 2 are vertically connected. And the air cooling blades 2 are uniformly distributed along the radius line of the end surface of the starting gear 1 in a circumferential manner.
Preferably, the starting gear 1 and the air-cooling blade 2 are integrally formed. The material is modified POM plastic, and the part molding is completed through injection molding; the integrally injection-molded part has high reliability and light weight. The strength of the starting gear 2 needs to meet the electric starting requirement of the engine; meanwhile, the air-cooled blade 2 meets the cooling requirements of a cylinder cover and a cylinder body of the engine. Referring to fig. 2, there is shown an installation schematic of the present invention. When the air cooling device is used, the starting gear 1 and the air cooling blades 2 rotate anticlockwise under the driving of a crankshaft of an engine, and the arrow points to the direction of air delivery of the air cooling blades 2 in the operation process, so that cooling and heat dissipation of the head (heat dissipation body) of the cylinder are improved.
The structure of the present invention has been described above with reference to the accompanying drawings, and the embodiments are not to be construed as limiting the present invention, and those skilled in the art can make modifications as needed, and various changes and modifications can be made within the scope of the appended claims.
