Tribological Properties of Biodegradable Universal Tractor Transmission Oil
Journal Title: Tribology in Industry - Year 2016, Vol 38, Issue 2
Abstract
The annual consumption of lubricants in the world is around 40 million tons out of which less than 40 % are collected and properly processed meaning regeneration, re-refining and controlled incineration while the rest is disposed without control thus contaminating soil, water and atmosphere. It's one of the reasons that the last twenty years the environmentally friendly lubricants are more and more used. For the production of environmentally friendly lubricants are mostly used vegetable oil. In the field of the application of environmentally friendly lubricants attention should be given to the technical requirements including protection from the wear, corrosion protection, high load carrying properties and fulfilment of all the requirements imposed by the producer of the mechanical system. This paper presents development and testing of the biodegradable universal tractor transmission oil (UTTO) based on the vegetable oils. Tribological properties of the oils based on rapes oil, sunflower and soya, after corresponding testing, compared with the features of the commercially available mineral universal tractor transmission oil.
