Prerequisites for installation
NOTICE
Damage to the gear unit/gearmotor due to improper installation.
Damage to property.
• Observe the following notes.
Make sure that the following requirements are met before you start installing the unit:
• The drive has not been damaged during transportation or storage.
• The entries on the nameplate of the gearmotor match the voltage supply system.
• In case of abrasive ambient conditions, the output end oil seals must be protected
against wear.
• Output shafts and flange surfaces must be completely free from anti-corrosion
agent and any kind of pollution. Use a commercially available solvent to clean the
flange surfaces. Note that solvent damages the oil seal. Do not let the solvent
come into contact with the sealing lips of the oil seals.
•
For standard drives:
– Check if the gear unit/gearmotor is designed for the ambient temperatures. For
the application limits refer to the technical documentation, the nameplate or the
lubricant table (see chapter "Lubricant table (
– Make sure the environment contains no hazardous substances (oils, acids,
gases, vapors, dusts,...) or radiation.
•
For special designs:
– Check if the gear unit/gearmotor is designed for the ambient temperatures. You
find the application limits on the nameplate.
•
With helical-worm/SPIROPLAN
®
gear units:
– Note that no large external mass moments of inertia must be present, which
could exert a retrodriving load on the gear unit.
– Note the self-locking at η’ (retrodriving) < 0.5.
Calculation of η’: η’ = 2- 1/η
•
Servomotor mounting:
– The drive may only be mounted if it is ensured that after the mounting the drive
will be sufficiently ventilated. Ventilation prevents heat build-up.
4.1.1
Required tools/resources
The following tools and resources are required for the mechanical installation:
• Wrench
• Torque wrench for:
– Gear unit mounting
– Shrink disks
– Motor adapter AQH or EWH
– Input shaft assembly with centering shoulder
