Patent ID: 7527422

Claim:
A drive unit for a twin-screw machine with two screw shafts ( 5 , 6 ), which are rotationally drivable in the same direction, and which have an axial spacing a, with two output shafts ( 8 , 9 ), which have mutually parallel axes ( 15 , 16 ) with an axial spacing a, which are configured for coaxial connection to the screw shafts ( 5 , 6 ) and which in each case are provided with a crown gear ( 40 , 41 ) which does not collide with the adjacent output shaft ( 8 , 9 ), and with a drive motor ( 24 , 25 ) which is configured as a torque motor and has a stator housing ( 32 , 33 ), a rotor ( 34 , 35 ) which has an axis of rotation ( 28 , 29 ) and which is rotatably arranged in the stator housing ( 32 , 33 ) and at both ends of the rotor ( 34 , 35 ), outside the stator housing ( 32 , 33 ), in each case a driven pinion ( 36 to 39 ) which in each case is coupled with one of the crown gears ( 40 , 41 ).
