Abstract

A new tightening method for the rotary shouldered connection (RSC) has been developed. In the developed method, the coefficients of friction between mating thread surfaces and between mating shoulder surfaces can be accurately and separately detected by sinultaneous loading of torque and compressive force to RSC. The tightening experiments have been achieved to verify the serviceability of the developed method. The 1/4 scale model of NC50 are used as the test model of RSC. The scatter band of axial force on RSC has been reduced within the error of ±10 % under lubricated conditions by grease with MoS2. The reliability of the method is compared with Baryshnikov's method.
