7.1
Cleaning
If the surface of the gear unit/geared motor is dirty, sufficient heat dissipation through the ambient air is no longer
possible. As a result, impermissibly high operating temperatures could occur, which reduce the lubricating effect of the
lubricant and accelerate its aging. This has a negative effect on the service life of the gear unit/geared motor. Furthermore,
the thermal winding protection may force a shutdown of the drive before the drive has reached its nominal values.
Determine the cleaning intervals according to the expected operating conditions, but every 12 months at the latest. Clean
the gear unit/geared motor according to the following instructions.
WARNING! Moving machine parts can cause serious injuries or even death!
Before performing work, switch
off the machine with the main switch and secure the switch from being turned on again.
WARNING! Falling gravity-loaded axes or vertical axes can cause serious injuries or even death!
Move
gravity-loaded axes or vertical axes to their lowest position and lock or brace them mechanically before entering the danger
area.
CAUTION! The surface of the drive can reach temperatures over 65 °C during operation!
Allow the drive to
cool sufficiently before working on it. Wear gloves.
ATTENTION! Improper cleaning can cause damage to the gear unit/geared motor!
Do not use steam jet
cleaners, high-pressure cleaners or compressed air to clean the gear unit/geared motor, as this can result in water and dirt
entering the interior of the gear unit/geared motor through the seals and can damage it. In addition, do not use solvents, as
these can damage the seals and the nameplate. Comply with the following instructions.
§
Remove dust and chips with a suitable industrial vacuum.
§
Remove contamination from the surface of the gear unit/geared motor with a suitable industrial cleaner.
7.2
Inspection
Perform regular inspections on the gear unit according to the following specifications. Inspect the attached motor in
accordance with the documentation of the motor manufacturer.
WARNING! Moving machine parts can cause serious injuries or even death!
Before performing work, switch
off the machine with the main switch and secure the switch from being turned on again.
WARNING! Falling gravity-loaded axes or vertical axes can cause serious injuries or even death!
Move
gravity-loaded axes or vertical axes to their lowest position and lock or brace them mechanically before entering the danger
area.
CAUTION! The surface of the drive can reach temperatures over 65 °C during operation!
Allow the drive to
cool sufficiently before working on it. Wear gloves.
The gear units are filled with synthetic lubricant at the factory. With proper use, the lubricant does not need to be changed
over the entire service life of the gear unit. The specification and fill volume of the lubricant is specified on the nameplate
of the gear unit.
Interval
Task
Every 3000 operating hours or
every 6 months
Check shaft seal rings for external damage and leaks
Annually
Check paint for damage and touch up if necessary
Check tightening torques of the screw connections between gear unit/machine and
between gear shaft/drive elements (see the chapter
Tightening torques
)
