Was determined the constructional parameters of brake pulley with its dynamic and heat load. Were established the change regularities of: interference overlap factor; dynamic friction factor and its stability; heat conduction factors. Were received the results of multicriterial projection of brake pulleys and the reasonable exploitation parameters of prevail brake processes with belt and block brake of drilling winch.56355635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
