Abstract
Cilj ovog rada bio je analizirati trošenje diskova tanjurače sijačice za direktnu sjetvu koji su nastali tijekom eksploatacije, kroz analizu stvarnih iznosa trošenja (gubitka mase i smanjenja promjera diskova tanjurače), kao i analiza oblika i mehanizma trošenja koji su isto uzrokovali. U radu je analizirano trošenje diskova na sijačici „Pöttinger Terrasem C6 fertilizer“ u eksplotaciji tijekom 2 godine i obraĎeno oko 4000 ha. UtvrĎen je prosječni gubitak mase od 1,99 kg, odnosno 32,91 %, te prosječni gubitak promjera od 77,13 mm, odnosno 15,08 %. Iz podataka o gubicima mase i promjera vidljivo je da su se najviše trošili krajnji bočni diskovi (1., 2. i 3.). Trošenje diskova je uglavnom nastalo mehanizmom abrazije i djelomično mehanizmom tribokorozije materijala, dok trošenje nastalo umorom površine nije uočeno. Kako bi se produţio vijek trajanja materijala u zaključku su navedene neke mjere za zaštitu od trošenja.
Abstract (english)
The aim of this work was to analyze the wear of disc seed drills for direct seeding that occurred during exploitation, through the analysis of the actual amount of wear (loss of mass and reduction in diameter of disc discs), as well as the analysis of the form and mechanism of wear that caused the same. The paper analyzed the wear of the discs on the seed drill "Pöttinger Terrasem C6 fertilizer" in operation for 2 years and cultivated about 4000 ha. An average weight loss of 1.99 kg, or 32.91%, and an average diameter loss of 77.13 mm, or 15.08%, were determined. From the data on mass and diameter losses, it is evident that the end side discs (1st, 2nd and 3rd) were the most worn. Disc wear was mainly caused by the mechanism of abrasion and partially by the mechanism of tribocorrosion of the material, while wear caused by surface fatigue was not observed. In order to extend the service life of the material, some measures for protection against wear are listed in the conclusion.
