Disassembly and replacement
This section describes the disassembly and
the replacement of a planetary gearbox.
11.1 Required tools
• Bench vise with braces
• Fork wrench DIN 894 or DIN 895
• Hexagon socket wrench DIN 911
• Hook wrench
• Fork wrench
11.2 Disassembling
Proceed as follows when disassembling the
planetary gearbox:
1.
Clamp the tightening spindle at the mo-
tor carefully into a bench vise.
2.
Hold the tightening spindle tightly and
loosen the connection of the planetary
gearbox to the adapter or measurement
transducer on the output drive side.
– Size 2: Loosen the connection using
a suitable fork wrench.
– Sizes 3, 4 and 5: Loosen the union
nut of the adapter or measurement
transducer using a suitable fork
wrench and then pull the adapter/
measurement transducer out of the
mating teeth in the housing of the pla-
netary gearbox.
CAUTION
Hot surfaces possible, particularly
on motor housings and gearboxes!
Risk of injury! Risk of burns!
X
Do not touch device housing sur-
faces at heat sources! Risk of burns!
X
Do not touch housing surfaces of
motors and gearboxes! Risk of burns!
X
Depending on the operating conditi-
ons, temperatures during or after
operation may exceed 60 °C
(140 °F).
X
After switching off the motors, allow
them to cool down sufficiently before
accessing them.
X
Wear protective gloves or do not
work near hot surfaces.
NOTE
Incorrect assembly/disassembly of
planetary gearbox possible!
Material damage and malfunction of the
planetary gearbox in later operation.
X
During assembly/disassembly, it is
imperative that you hold the planetary
gearbox horizontally. Otherwise,
there is the risk of the gears and
needle bearings loosening from the
gearbox.
NOTE
Incorrect motor assembly/disas-
sembly possible!
Material damage to the motor due to in-
correct clamping into a bench vise.
X
Clamp the motor only slightly and
use extensive braces.
