Date May 15, 1997The reduction gear unit, particularly for use in twin-screw extruders comprises an input shaft (10), a first output shaft (12) and a second out put shaft (14) located parallel to and close to each other and associate with a respective worm screw, and a first gear train (16) and a second gear train (18) for connecting the input shaft (10) to the first output shaft (12) and to the second output shaft (14) respectively. The second output shaft (14) is long than the first output shaft (12) and is connected to the second gear train (18) by a part which is not alongside the first output shaft (12). Moreover, the input shaft (10) has a torsionally resilient portion (40) between its parts connected to the first gear train (16) and the second gear train (18) respectively. |
