The work is based on the method of generalized variable operating parameters of new types of hydraulically driven disk-shoe brakes of drilling winches with forced air-nano-liquid cooling of their friction pairs, twe he following has been established the colling: Cooling occurs when operating in the range of surface-volume temperatures above the permissible ones for friction lining materials having more than 400 ºС. All this is possible due to the use of the low-melting metal nanopowders diluted with water or acetone for the liquid. This made it possible to increase significantly he thermal conductivity coefficient of the nanofluid and Based on the method of generalizing dimensional and dimensionless design and operational parameters with the involvement of calculated and experimental data, a relationship with the internal parameters of the nanofluid washing the surface of the disc friction belt of the nanofluid is established. In addition, a relationship is established between the washing surface of the disc friction belt and the external parameters of the washing air flows. All this, in turn, will make it possible to increase the durability of friction pairs of disc-shoe brakes of drilling winches and reduce the downtime of drilling rigs.
