Mounting
The gearboxes are lubricated for life.
The gearboxes can be mounted in any position.
The mechanical power transmission system is maintenance-free.
Transmission elements
• Fit or remove transmission elements only using suitable equipment.
• For fitting the transmission elements use the center hole in the shaft.
• Avoid impacts and shocks.
• In case of a belt drive, tension the belt in a controlled manner according to manufacturer information.
• Be sure to carry out mounting in a manner free from distortion.
• Compensate minor inaccuracies by suitable flexible couplings.
Fastening
• Use screws with a minimum property class of 8.8.
• Observe prescribed tightening torques.
• Secure against unintended loosening.
• For alternating loads, we recommend applying anaerobic curing adhesive between flange and mounting
surface.
The mounting steps described in the following are the same for all gearbox types.
Thus, they are shown schematically as an example.
