3.8 Flange version gear units (option: F, FK, VL2/3/4/5, KL2/3/4)
NOTICE!
Risk of gear unit damage from distortion
• Flange version gear units must only be bolted to the flange of the driven machine.
• The bolting surface of the driven machine must comply with the tolerances in section 7.5
"Tolerances for bolting surfaces".
• The flange of the driven machine must be free of vibration and torsionally rigid
• The bolting surfaces of both flanges must be clean.
The diameter of the hole circle and the size of the threaded holes on the flange of the gear unit must
be obtained from the specific dimension sheet for the order.
3.9 Motor base frame (option MF)
A motor base frame is a steel structure for pre-assembled drive packages in a horizontal position. It
serves for jointly mounting the gear unit, (hydro) coupling, motor, and, where applicable, also a
mechanical brake, and it includes the necessary protective devices (e.g. hood). The steel structure is
supported by several fastening feet.
