Treść
White and natural base oils are assessed as candidates for the formulation of ecological gear oils. They arecompared to ‘classical’ mineral and polyalphaolefins-based oils in scuffing four-ball and gear tests. Fourfully formulated gear oils were prepared by blending each base oil with the package of extreme pressure(EP) additives, an anti-foam additive and an anti-oxidant. It is shown that the resistance to scuffing of thewhite oil is comparable to the classical oils, but the natural (rapeseed) oil reduces resistance to scuffing,because the used EP additives may not be suited to the rapeseed ‘matrix’ producing adverse effects. Thus,rapeseed-based gear oils can be used only for the lubrication of gears working under moderate load condi-tions. It is also indicated that, when comparing the mechanisms of tribochemical action of the EP additivesin the four-ball tribosystem and meshing teeth, care should be taken, because the conditions in the contactzones are different.
