An actuator includes a motor driving a worm, a gearbox, and a motor control module. The gearbox includes a gearbox housing, a worm wheel for meshing with the worm, an output mechanism fixed to the worm wheel. The gearbox housing defines worm chamber and worm wheel chamber. The motor control module includes a control module housing, a printed circuit board and a connector of the printed circuit board. The control module housing defines a control module chamber and the connector is mounted at an open end of the control module chamber. The control module housing is connected with the gearbox housing. The control module chamber and the worm wheel chamber are located on opposite sides of the worm chamber. An isolation slot is defined between the control module chamber and the worm chamber.

A gearbox assembly for a twin-screw extruder comprises a speed change gearbox for adjusting a screw shaft speed of two screw shafts of the twin-screw extruder, a distribution gearbox allowing the screw shafts to be coupled thereto, and a speed reduction gearbox. The speed change gearbox and the speed reduction gearbox are configured such as to be separable from each other, wherein the speed change gearbox is arranged at a driving end while the speed reduction gearbox couples the speed change gearbox to the distribution gearbox. Due to the fact that the speed change gearbox is configured as an individual gearbox unit arranged at the driving end, an adjustment of the screw shaft speed is easily possible by replacing the speed change gearbox. As a result, a high flexibility and productivity are obtained in the operation of the twin-screw extruder.

A hollow-type strain wave gearing unit (1) has a sealing member (14) for sealing a gap (15) opening to the inner peripheral surface of a unit hollow portion (5) passing through in an axis (1a) direction. The gap (15) includes a gap section (15b) between an outer peripheral side end race (48b) on the wave generator side and a boss side end face (108), both faces opposing each other in the axis (1a) direction, and the sealing member (14) is assembled therein. The gap section (15b) is formed in a state partially entering the inside of the inner ring (11b) of the second bearing (11) supporting the wave generator (4). It is possible to realize a hollow-type strain wave gearing unit with a sealing mechanism that is suitable for increasing the inner diameter of the unit hollow portion and for reducing the unit axial length.
