Abstract: An assembly for mounting a driven machine and drive includes a support frame on a foundation. The drive is secured to a set of mounting plates which are disposed directly on the support frame. The driven machine is carried by a set of mounting units each of which comprises a pair of spaced carrier elements and a mounting plate arranged between the carrier elements. The carrier elements and the respective mounting plates have cooperating guide means which enable the mounting plates to be adjusted relative to the support frame. In mounting the driven machine and its drive, the two are roughly aligned by shifting the mounting units and/or the mounting plates for the drive on the support frame. Once the driven machine and its drive have been roughly aligned, the mounting units as well as the mounting plates for the drive are anchored in the foundation and welded to the support frame.
