Abstract
Drive apparatus (1, 101), in particular for driving a worm of an injection molding machine, which worm is arranged coaxially with respect to an injection molding cylinder, having a housing (9, 109) which is mounted such that it can be displaced in an axial direction of the housing (9, 109) and is fixed rotationally, an output shaft (21, 121) which is mounted non-displaceably and rotatably in the housing (9, 109), a rotational drive (5) which is arranged in the housing (9, 109) for the rotational drive of the output shaft (21, 121), and a translatory drive (3) which is arranged in the housing (9, 109) for the translatory drive of the housing (9, 109).
Claims10
A drive apparatus for driving a worm of an injection molding machine, which worm is arranged coaxially with respect to an injection molding cylinder, comprising:
- (a) a housing which is mounted such that it can be displaced in an axial direction of the housing and is fixed rotationally;
- (b) an output shaft which is mounted non-displaceably and rotatably in the housing;
- (c) a rotational drive which is arranged in the housing for the rotational drive of the output shaft;
- and
- (d) a translatory drive which is arranged in the housing for the translatory drive of the housing,
- wherein the translatory drive comprises a spindle rotor which interacts with a spindle shaft, the spindle shaft is mounted in a rotationally fixed and axially non-displaceable manner.
