INCREASE OF WEAR RESISTANCE IN PARTS AND ASSEMBLIES AND EFFICIENCY OF TRACTORS BY AN APPLICATION OF RATIONAL TEMPERATURES IN FUEL-LUBRICATING MATERIALS (FLM)

The work covers the assemblies and sets of the fuel systems and transmissions operating in FLM medium without temperature control. The aim is to develop the scientifically-substantiated ways to increase the wear resistance of parts and assemblies and efficieng of the tractors by an application of the rational temperatures in the fuel-lubricants. The model has been created, and the mechanism and nature of abrasive particle interaction with filter and friction surfaces have been revealed; the analytical relations of abrasive particle penetration probability into the clearance have been obtained; the procedure of wear measurement has been developed. The rational values of FL temperatures providing the intensity decrease of conjugation wear 1,2-1,3 time have been determined; the fuel system and loader designs decreasing the consumption of fuel and electric power have been developed. The investigation results are realized in the text-books for higher schools and technical secondary schools, in the Vladimir Tractor Works, in the Joint-Stock Company "Repak" (c. Penza), in the Krasnoufimsk Works. The wear resistance of conjugations was increased 1,2-1,3 time, the fuel consumption has been reduced by 3-5%Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
