<p>The reduction gear unit, particularly for use in twin-screw extruders comprises an input shaft (10), a first output shaft (12) and a second output shaft (14) located parallel to and close to each other and associated 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 longer 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.</p> |
