The development and the use of the ball bearings with the antifrictional protective layer from polymeric composite material

Abstract

The presented article deals with the issues of environmental safety since the annual consumption of oils in the world is about 50 million tons of which only a quarter are reused, are disposed of or at least burned, the rest is merged into water bodies, soil, sewage, and is dispersed in the atmosphere. By estimates of ecologists more than 40% of the world's water is covered with a film of used oils. The purpose of the work was to develop a lubricant for rolling bearings that would not require replacement during the entire service life, and also withstand high temperatures of up to 250 ° C while being environmentally safe. As a result of the work, it was proved that the use of a protective polymer layer based on polytetrafluoroethylene and antifriction fillers in ball bearings ensures a 1.7 to 3.5-fold increase in the durability of the products, prevents jamming of the ball, and also eliminates the use of lubricants that pollute the environment.
