【Abstract】 In this paper, the appearances of loss in effectiveness of the drilling rig brake couple are discussed. According to the principle of friction, the temperature of the friction surface is regarded as a effectiveness criterion of the brake couple. The formulas for calculating the temperature are derived. With the help of the results calculated by electronic computer, the temperature curves of brake drum friction surface,represented by the Model 130-2 rig, are set up.The achievement provides a theoretical basis and a method for correct design, rational application and further study of thermal con-dition of th,e rig brake couple.更多还原
