Sažetak

One of the biggest problems today is how to preserve planet from the ever growing pollution and how to preserve natural resources for future generations. The consequences are more and more noticeable through climate changes, pollution of water streams, soil and atmosphere. The big part of the environment pollution is caused by the lubricants. The annual consumption of lubricants in the world is around 40 million tons and more than 60% of it is spread without any control into the environment. The lubricants are mostly of mineral origin, they are toxic and not readily biodegradable. The catastrophe due to the intensive pollution of environment, threatening the planet Earth, draws the public attention and ecological awareness demanding the development of the ecologically acceptable lubricants. The ecologically acceptable lubricants when put into contact with the environment produce minimum of harmful effects. To be ecologically acceptable the lubricant must be biologically degradable and nontoxic. The most important raw material for the formulation of the ecologically acceptable lubricants is plant oils being biodegradable, nontoxic and represent renewable resource.
This paper presents the testing of the biodegradable oil for the lubrication of the chains in chain saws. Physical and chemical properties are tested as well as tribology characteristics on the tribometer “block on disc”. Disk material, having the diameter of 35 mm and block having the dimensions 6.3x10x15 mm3 is the steel 16MnCr5. The testing time on tribometer is 60 minutes with the load of 30, 100 and 300 N and with the sliding velocity of 0.8 m/sec. The results present tribology characteristics of formulated biodegradable oil for the lubrication of chains in chain saws compared with commercially available mineral oil.
