Beschreibung
Zusammenfassung:	The invention concerns a device for the relief of dynamic torsional deformation of a transmission shaft of the type which provides at least a proximity sensor (11 and 12) suitable for detecting the passing of the teeth of a gear wheel (10) keyed onto the shaft in question, at least a pulse height analyser (30) capable of generating a signal proportional to the instant speed of the transmission shaft. According to the invention, the said device provides: a) a circular buffer (110) equipped with as many memory locations as there are teeth of the above mentioned gear wheel, in which the apparent instant speeds are stored, which are generated by the imperfections of the gear wheel, b) means for transmitting the said instant apparent speeds to a subtractor (50), which the instant speed measured by the proximity sensor (single figure) reaches synchronously.
