5.3.1 Remedying operational malfunctions
Warning!
Gefahr
Tampering with the gearbox can lead to unintentional interruption of the power flow
between the prime mover and the driven machine.
• It is not permitted to stay in the unsecured area around the gearbox (e.g. swivel
range of a robot actuated by the gearbox nor stand under loads that are raised
with the help of the gearbox).
• Observe the gearbox temperature and allow the gearbox to cool down if neces-
sary.
• Secure the gearbox against unintentional startup or unintentional interruption of
the power flow.
• When disconnecting the gearbox from the prime mover or driven machine, the
gearbox must be disengaged from all loads. When disconnecting, any static
torques still present in the power train or external loads on the gearbox must be
taken into account.
5.3.1.1 Causes and remedies for possible fault states
Fault state
High operating temperature
Loud noise during operation
Possible causes
Gearbox unsuitable for load
High ambient temperature
Insufficient
convection, heat conduction
Motor is heating the gearbox
Deposits on the
gearbox surface
Gearbox too close to a heat
source
Gearbox unsuitable for load
Gearbox damage (bearings,
gearing, lubricant used up)
Motor attachment or radial/
axial run-out of the motor out
of tolerance
26
Potential solution
Compare the load with the
technical specifications
Ensure sufficient cooling by
convection or forced-air
ventilation
Optimize heat conduction in
the application
Check load on the motor
Clean the gearbox surface
Shield the gearbox or relocate
heat source
Compare the load with the
technical specifications
Contact our customer service
Check radial/axial run-out of
motor and remount motor
