dc.description.abstractThe paper analyses the operating conditions of band-pad brakes of drilling winch, materials and coatings for strengthening the metal elements of friction pairs. Methods of researching the thermal and stress-strain state of elements of brake friction units are considered. The problem of the development and theoretical research of the properties of new polymer materials with gradient properties for the production of friction overlays of band-pad brakes with improved operational characteristics is singled out. A mathematical model heat transfer through friction overlays of band-pad brakes of drilling winches with a variable coefficient of thermal conductivity of the material based on the thickness of the specified overlays has been developed. According to the developed mathematical model, an analytical study of the process of heat transfer through the friction overlays of band-pad with variable coefficient of thermal conductivity of their polymer material according to the thickness of the friction overlays was carried out according to different laws. It was established that the highest intensity of heat removal from the friction zone of the brakes is ensured when the thermal conductivity coefficient changes according to the law described by a second-order polynomial. Keywords: polymer brake overlay, thermal conductivity coefficient, wear, functionally gradient material, coating, mathematical model.en_US
