Analytical study of heat transfer through friction overlay of band-pad brakes

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