Use of biological oils for agricultural machinery

Purpose. Improvement of tribotechnical properties of organic oil to ensure the reliable operation of nodes and units of functional systems of mobile agricultural machinery. Methods. The methods of estimation of tribotechnical properties of lubricants of biological origin were used. Results. The methodology of improvement of tribotechnical properties of biological oil for mobile agricultural machinery is considered. As a result of the conducted researches it is established that materials that work in the environment of biological lubricants have the best resistance to wear, in addition, the wear in the environment of biological oils is practically independent of the tribosystem load. However, organic oil is prone to negative processes that lead to polymerization and oxidation. To improve the tribotechnical properties of organic oil, it is necessary to introduce special additives and additives in it, which will allow to level these processes. Conclusions. 1. It is established that the use of blended oil is promising. The widespread use of vegetable oil in the production of lubricants will solve some of the complex environmental problems. 2. The chemical and tribotechnical properties of organic oil are better than those of mineral oils, but they are inferior to the resistance to oxidation, so it is advisable to introduce multifunctional additives and additives to improve its basic characteristics. However, additives to organic oils have structural components of different origin, they are unsystematized and have no scientific justification to ensure the wear resistance of the surface layers of friction pairs of nodes and aggregates of mobile machinery. 3. As a result of the researches it was established that the wear of the samples for friction steam “spool – the valve body” decreased in the environments: rapeseed oil by 62.5%, and with 1.0% by the addition of ICF-18 by 75%; of sunflower oil by 62.5%, and with 1.0% by the addition of MKF-18 by 80%.
