<p>The coupling has at least two weights (12), each of whose centre of gravity is at a distance from the axis (20) of the two main shafts (2, 5) serving as input and output. The weights are rotatably mounted in bearings (7, 8) which are rigidly connected to one of the main shafts (2, 5). Disposed between the other main shaft (2, 5) and the weights (12, 13) are transmission means (17, 18) tending to rotate the weights (12, 13) in relation to a zero position which the weights take up when the main shafts (2, 5) are running off-load and in synchronism with one another. The coupling has a torsional resistance which decreases with increasing load - i.e., the coupling is a mechanical coupling which has a very soft characteristic on full load. Also, the coupling helps to obviate the transmission of torsional vibrations from one of the main shafts (2, 5)- as a rule, the input shaft (2) - to the other main shaft - as a rule, the output shaft (5). <IMAGE></p> |
