| 摘要: |
| 本文从理论上阐述收割机齿纹动刀片的切割机理。分析了齿纹刀片的磨损规律、组成刀片齿纹诸多空间角度参数的作用及其对“自磨锐”性能的影响。通过对齿纹刀片的外形、结构和参数的合理设计,使刀片在切割茎秆的磨损过程中得到自身的刃磨,获得优良的“自磨锐”和“长齿”性能,从而发挥刀片金属材料的充分利用率,达到延长刀片使用寿命的目的。 |

| Abstract: |
| Theoretically,this paper describes the cutting principle of serrated blade of harvester,and analyses the wearing laws of serrates blade,the function of several space angle parameters forming the serrated sections of the blade annd its effect upon self-sharpening property.Rational design of the outline shape,structure and parameters serrated blade can make the blade itself sharpen in the wearing process of cutting stalks so as to obtain "self-sharpening" and "growing tooth" properties.In this way,the metal materials used for making the blade can be fully used,and also,the service life of the blade may be prolonged. |
| Key words: self-sharpening blade,growing tooth property,topserrated blade,structural parameters,grain combine |
