Ecology In Tribology: Selected Problems of Eliminating Natural Oil-Based Lubricants from Machine Friction Couples
Abstract
The elimination of mineral oil-based lubricants from machines has multiple beneficial effects on the natural environment. Firstly – these lubricants are a direct threat to the environment in the event of leaks; secondly – their elimination reduces the demand for crude oil from which they are obtained. In addition, in many cases, e.g. when replacing traditional lubricants with water, friction losses in the bearings can also be reduced due to the lower viscosity of the water, which reduces the energy dissipation in machines. On the other hand, the introduction of self-lubricating materials or water-lubricated bearings causes problems related to the need to adapt the design of machines and materials used to new operating conditions and changed properties of the lubricants. In the paper, selected examples of problems related to the use of ecological lubricants are discussed. The high cost of PEEK based polymers resulted in the emergence of cheaper substitutes on the market; however, in the conducted research, the substitutes presented worse properties than those declared by their manufacturers
