Abstract: The 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.
