摘要
Polymer and composite machine elements are used more often in agricultural machines. The main advantages are: lubrication free operation meaning a method of environment protection, low weight (fuel economy and reduction of soil compression by machines) and wear resistance [1]. Generally some types of polymers are considered to be excellent anti-wear materials, but the detailed wear effects of different soils on polymers are not clarified yet. [2, 3] At our research tests we examined the abrasive wear behaviour of polymer/steel gear pair, contacting seven different soil types. The article gives a brief review about the results and conclusions.
