The tapered screw joints are widely used in the formation of the drill string. They consist of two parts - a box and a pin. during the process of screwing box and a pin the contact pressure between thread surfaces arises, the magnitude of which affects the intensity of wear on these surfaces. For the first time, the authors offer in this work to ch...

 Finding the coefficient of rolling friction (CRF) by the inclined plane method is similar to the manner used in establishing the coefficient of sliding friction. For the rolling case, the difficulty arises from the fact that the usual devices employed in angular measurements present errors greater than the effective angle. The paper surmounts...
