Gearbox With Foot Mounting - Siemens SINAMICS G115D Operating Instructions Manual

Additional information on the SIMOGEAR geared motor
11.3 Specific data gearbox
When biodegradable oils or oils for the food-processing sector are used, the gearbox is filled
completely with operating oil. The gearbox is closed air-tight with a sealing plug or a pressure
venting with transport fixture.
Do not lower the oil level during short-time commissioning for 10 minutes in no-load
operation.
11.3.8

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 deviation in flatness of the gearbox's contact surface may not exceed the following
values:
For gearboxes up to size 89: 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 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.
