Possibilities of Using Ecological Fluid in Agriculture

Abstract

This paper deals with the issue of using ecological oils in the sliding pair of hydraulic and transmission systems working in the area of agriculture. The sliding pair included a B 60 bearing and a journal with contact surface made of 14 220 steel. The experimental tests were carried out with two oils: the Fuchs Plantohyd 46 S ecological oil and PP 80 reference oil (producer: Slovnaft) which is a commonly used lubricant in given conditions. The results of the experiments were statistically processed and based on them, friction coefficient and temperature, both depending on the test duration, was evaluated. Consequently, the weight loss and roughness change of both tribological elements were statistically processed.
