4.4 Gearbox with foot mounting
4.4
Gearbox with foot mounting
NOTICE
Do not subject the gearbox to excessive stress when tightening the fastening bolts
The foundation must be level and free from dirt.
The levelness deviation of the gearbox support must not exceed 0.1 mm.
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, which cannot be measured at a standstill.
When using foundation blocks to fasten the gearbox to a concrete foundation, suitable
recesses should be made in the foundation.
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 strength class 8.8 or higher for the foot mounting.
Observe the tightening torque.
4.5
Gearboxes in foot or flange version
NOTICE
Do not subject the gearbox housing to excessive stress by adding add-on elements to the
foot or flange
Add-on elements must not transmit forces, torques and vibration to the gearbox.
The gearbox must only be mounted at either the flange or the foot to transmit force and
torque in order to prevent excessive stress on the gearbox housing, see Gearbox with foot
mounting (Page 20).
