Gearbox with foot mounting

The foundation should be designed in such a way that no resonance vibrations are created and
no vibrations are transmitted from adjacent foundations.
The foundation structure on which the gearbox is to be mounted must be torsionally
rigid. It must be dimensioned according to the weight and torque, taking into account the
forces acting on the gearbox. If the substructure is too weak, it will cause radial or axial
displacement offset during operation that cannot be measured at a standstill.
If the gearbox is fastened to a concrete foundation, use foundation blocks for the appropriate
recesses.
Align and grout the slide rails into the foundation.
Align the gearbox carefully with the units on the input and output side. Take into account the
elastic deformation due to operating forces.
Prevent displacement from external forces due to lateral impacts.
Use stud bolts or headless screws of property class 8.8 or higher for the mounting foot.
Observe the tightening torque.

Gearbox with flange mounting

Note
Siemens recommends an anaerobic adhesive to enhance the friction lock between flange and
mounting surface.
