PROCEDIMIENTO DE APRIETE DE UN ENSAMBLE QUE COMPRENDE UN ELEMENTO DE ENSAMBLE ROSCADO.

摘要

A process is disclosed for tightening a joint having a threaded joint element. This invention makes it possible to apply a predetermined tightening force to the joint. The process uses the real factor of proportionality (K) between the force for tightening the joint and the screwing torque applied to the threaded element which is determined after a preliminary screwing cycle and unscrewing cycle have been performed. Application is particularly to automation of tightening of prestressed joints.
