    Abstract: A device for monitoring clamping of an assembly including at least one part to be clamped, an internally threaded element and an externally threaded element engaged in an internal thread of the internally threaded element. The device includes a driver to rotate one of the elements including the internally threaded element and the externally threaded element to clamp the assembly and a first sensor to measure a screwing torque of the driver, a tool for holding fixed against rotation the other of the elements including the internally threaded element and the externally threaded element, a second sensor to measure a reaction torque of the holding tool, a mechanism for determining a third parameter chosen from a time elapsed from a given time and a screwing angle from a reference position, and a calculation system to determine pre-tension in the externally threaded element.

    Abstract: A method of monitoring the clamping of an assembly by a threaded fastener. One element of the threaded fastener is rotated by a driver while the other is held stationary by a holding tool. The screwing torque and reaction torque of the holding tool are measured. Analyzing their evolution as a function of a third parameter makes it possible to determine accurately the pre-tension in the assembly. The disclosure herein further relates to a clamping method employing a real-time monitoring method of this kind. The disclosure herein also relates to a corresponding device for implementing a method of this kind.

    Abstract: A process for checking when tightening a threaded fastener that it has been tightened on the complete threads of the fastener. In order to do this the process comprises detecting different gradients in a tightening graph representing torque as a function of another parameter and comparing each gradient with predetermined values. According to the portions of graph detected and their gradient values it is possible to determine whether tightening is correct and has taken place on the complete threads of the fastener, or if not it is possible to identify a cause of failure.

    Abstract translation: 在紧固螺纹紧固件时检查其已被紧固在紧固件的整个螺纹上的过程。 为了做到这一点，该过程包括检测表示作为另一个参数的函数的扭矩的紧固图中的不同梯度，并将每个梯度与预定值进行比较。 根据检测到的曲线图及其梯度值，可以确定紧固件的紧固是否正确，并且已经发生在紧固件的整个螺纹上，或者如果不能确定故障原因。
