4.4 Fastening in the case of high shock loads
In the case of high shock loads provide additional suitable positive fastenings such as
cylindrical taper pins or spring pins.
NOTICE
Do not use spring washers, serrated lock washers, spring or toothed lock washers, cup
washers or conical spring washers as a substitute for the above positive connections
Do not subject the housing to excessive stress when tightening the fastening bolts.
4.5 Gearbox with foot mounting
NOTICE
Impermissible housing loadings when unevenness present
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 the following values:
For gearboxes up to size 88: 0.1 mm
For gearboxes as of size 108: 0.2 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 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 strength class 8.8 or higher for the foot mounting.
Observe the tightening torque.
