Досліджено вплив фізико-механічних властивостей матеріалу робочого органу, абразивних властивостей ґрунтів і конструктивних параметрів робочого органу на виникнення ефекту самозагострення. Отримані уточненні умови самозагострювання для робочих органів дискових ґрунтообробних знарядь. Set conditions of independent intensifying working organ soil-cultivating instruments. Influence of mechanical properties of material working organ, abrasive properties soils, structural parameters of working organ is investigational on the origin effect of independent intensifying. Got clarification of condition of independent intensifying for the workings organs of disk soil-cultivating instruments:
1. Value thickness and hardness of the strengthening and base layer should be a lifetime condition to
ensure R < Rɞ.
2. The thickness of the base layer should be as short as possible, while providing the necessary increase in
strength solid layer.
3. The hardness of hardened layer should be determined in relation to the base layer hardness depending
on the abrasive properties of soil.
4. Strengthening and exacerbate the line and must be subject to more intense wear that.
6. Sharpening angle must be at 28Û ... 30Û.
To achieve the effect independent intensifying working organ soil-cultivating instruments must fulfill five
conditions and the second and the third condition suggested by V.M. Tkachev for plowshares completely fair and intensifying working organ soil-cultivating instruments, the first condition is clarified, and 4 opposite condition is reversed.
