This fixing component is provided by the end closing cover (3), firmly connected to the drive unit (1). The retainer mounting consists of a wall retainer plate (2). The retainer plate has vertical angle plates for lateral guidance and axial fixture on the cover, and latches swinging inwards to support it. It is secured against twisting by a cam locking into a groove in the cover, or by holes enganged by stud bolts (33) screwing into the cover.</p> |
