| 摘要 |
The invention relates to a drive unit for at least one traction means (8), particularly in stage technology, comprising a winding drum, which is supported rotatably about a winding axis (4) and has at least one receiving region (6), on (each) of which a traction means that can be wound or unwound is received. A cylindrical driving region (14), on which a windable or unwindable belt-shaped driving means (12) is received, is arranged axially adjacent to the receiving region on the winding drum. Said driving means can be unwound from the winding drum and wound on a drivable driving drum (18), a driving torque acting on the winding drum thus being produced, or conversely can be unwound from the driving drum and wound onto the winding drum, rotation of the winding drum thus being permitted. Two drive motors (30) are provided, each having a drive shaft (34), the axes of rotation (37) of which extend in a drive plane arranged perpendicular to the winding axis. A drive wheel (38) is provided, which has a drive connection to the drive shafts and the axis of rotation (40) of which extends parallel to the winding axis, wherein the drive wheel has a drive connection to the driving drums (18). |
