НАНОТРИБОЛОГИЯ ПРИ ФРИКЦИОННОМ ВЗАИМОДЕЙСТВИИ МЕТАЛЛОПОЛИМЕРНЫХ ПАР ТРЕНИЯ ЛЕНТОЧНО-КОЛОДОЧНЫХ ТОРМОЗОВ БУРОВЫХ ЛЕБЕДОК

Abstract

Illustrated nanotribology spots contacts microirregularities metal-vapor friction belt drum brakes drawworks, based on their energy loading, conductivity and friction path of the contact points and the lifetime of the films on them. It is known that the rim brake pulley is an accumulator of heat energy, and the polymer pad drive positive (ions) and negative (electron) charge. The contact film lifetime determines energy loading aggregate contacts microirregularities friction unit spots. The main requirements for the contact patch microirregularities of the metalvapor
friction unit are as follows: low contact resistance, stability and durability. It is established that the resistance varied in the reduced (amine) and oxidized (imine) form polymer. Imine groups, probably more diffusely scatters electrons conductivity as compared with amine, and therefore a higher resistance to oxidation state. When burnout binders in the surface layers of the polymer lining above the permissible temperature of the materials, i.e, in electrochemical conditions in electrolyte solutions, it is possible to change the electric (free) surface charge over a wide range, i.e, to identify more clearly the effect of the field.
