Mechanical installation
Important notes
– check that all components are safely mounted,
– fasten all transport aids (eye bolts or support plates).
Danger!
Danger due to toppling or falling loads!
¯ The payload of the hoists and load handling devices must at least
correspond to the weight of the load.
¯ The load must be secured in such a way that it cannot topple or fall
down.
¯ Do not stay under a pending load!
EN
4.2 Transport equipment for gearbox
Danger!
The motors attached to the gearbox are partially equipped with eyebolts.
These are exclusively determined for mounting/dismounting the motor
to the gearbox and must not be used for the complete geared motor!

Preparation
Stop!
Do not place gearbox onto breather valve!
No ventilation measures are required for the gearboxes g500−S130 and g500−S220.
Gearboxes which are delivered with a ventilation unit are equipped with a label on the
gearbox.
Remove the transport locking device on the vent valve before the first commissioning.

Note!
Lenze delivers motors with condensation drain holes with sealed
condensation drain holes. The holes are sealed with a plastic plug or a
locking screw. This does not affect the type of protection and the motor is
protected against the ingress of foreign substances during transport and
operation. Further information, ( 36).

Coupling hubs
Note!
Standard hubs, clamping hubs and clamping ring hubs are
maintenance−free.We recommend checking the star−shaped spider and
system components when inspecting the drive.
Mounting the standard hub / clamping hub
1. Fit motor key (2).
– Fit enclosed key for drive sizes C, E, F.
2. Push the coupling hub over the motor shaft, mounting dimension m (see Fig. 2
and Tab. 2) must be observed.
EN
3. Secure coupling hub against axial movement using the fixing screw or clamping
screw (1).
4. Lay spider in the coupling claw on the gearbox side.
5. Align claws of the motor−side coupling hub with its counterpart.
6. Slowly push on motor, and bolt on to the gearbox flange.

1. Grease the contact surfaces of the motor shaft using a thin−bodied oil, e. g.
Castrol 4 in 1" or Klüber Quitsch Ex"!
Stop!
Do not use oil or grease with molybdenum−disulphide or high−pressure
additives, or grease pastes!
2. Push the coupling hub over the motor shaft, mounting dimension m" (see Fig. 2
and Tab. 2) must be observed.
3. Align the hub and tighten the clamping screws until they have contact.
4. Tighten the clamping screws evenly and crosswise with gradually rising torque
until the indicated tightening torque (see Tab. 2) is reached at all clamping screws.
In the intermediate steps, this procedure should also be repeated until the
indicated tightening torque is reached at all clamping screws.
5. Lay spider in the coupling claw on the gearbox side.
6. Align claws of the motor−side coupling hub with its counterpart.
7. Slowly push on motor, and bolt on to the gearbox flange.

Mounting
Attachment of gearboxes with hollow shafts and keyway
Stop!
Each screw must only be loosened by half a revolution per pass! Unscrew
all clamping screws by 3 − 4 threads.
2. Remove the screws next to the forcing threads and screw them into the other
threads until they have contact.
3. Tighten the screws in the forcing threads crosswise and step−by−step so that the
clamping ring is loosened.
4. Clean and grease all contact surfaces including threads and head of the clamping
screws before reassembly.
4.4.4 Attachment of gearboxes with hollow shafts and keyway
EN
1. Draw the gearbox with hollow shaft onto the machine shaft to be driven:
– Apply the supplied assembly paste (Fig. 4) on the shaft and in the hollow shaft
bore.
GT−GNG−GKR−011.iso GT−GNG−GKR−011_a.iso
Fig. 4 Application of assembly paste against fretting corrosion (included in the scope of supply)
Stop!
Take up forces only via the hollow shaft, and not via gearbox housing.
2. Secure the gearbox axially:
– The hollow shaft has snap ring grooves for axial securing. Parts used to fix the
shaft are not included in the scope of supply.

4.4.5 Mounting the shrink disc with a rotating cover
EN
Stop!
Do not dismantle new shrink disc.
Never tighten clamping screws before the machine shaft is pushed in.
Otherwise the hollow shaft may be deformed plastically. Protect the
shrink disc against contact while in operation by appropriate measures
(e.g. cover).
Degrease hollow shaft bore and machine shaft!

3. Thoroughly clean and degrease hollow shaft bore and machine shaft.
Note!
Thoroughly degrease the bore over the entire hollow shaft length to
make sure that remainders of the anticorrosion agent will not be carried
off into the area of the shrink disc when pushing on the machine shaft.
4. Slightly loosen clamping screws (2) one after the other, do not unscrew!
5. Push drive onto machine shaft.
6. Slightly tighten clamping screws manually.
7. Tighten clamping screws (2) one after the other (see Fig. 7) in several passes, with
rising torque, evenly until the indicated screw−tightening torque (see Tab. 5 ) is
reached at all screws.

Fig. 7 Explanation: "one after the other"
Tip!
Several (in general more than 5 ) passes are necessary until the full
tightening torque is reached at all screws!
The shrink disc is mounted correctly and fixed when the faces of the outer ring and the
inner ring are aligned (Fig. 8). Minimum misalignments are permissible.

tightening torque has priority over the value indicated in the table.

Tip!
For finding out the cause of non−reached torques of the shrink disc
connection, please go through the troubleshooting list in chapter 8.

Dismounting

Mounting
Mounting the shrink disc
Danger!
Loose drive components or drive components falling down may cause
injury to persons or damage to the machine. Secure the drive
components before disassembly.
1. Remove protective cap (1).
2. Loosen clamping screws (2) evenly one after the other each by ¼ revolution in
several passes. Do not unscrew clamping screws completely to prevent accidents!
3. Press off outer ring (see Fig. 8), if necessary. For this, loosen the outer ring using
the forcing threads and some clamping screws (number corresponding to the
forcing threads in the inner ring). For loosening the outer ring, screw in the screws
evenly to prevent canting. Press off the outer ring until loosened completely.
4. Remove the drive from the machine shaft.
EN
Stop!
Dismantle the shrink disc only for cleaning purposes. Afterwards, grease
bevel surfaces and screws using a solid lubricant with a friction factor of
m = 0.04.
¯ Suitable lubricants on molybdenum−disulphide lubricant (MoS2) basis are, e.g.:
– Molykote G Rapid (company Dow Corning)
– Molykote BR2 Plus (company Dow Corning)
– Molykombin UMFT1 (company Klüber Lubrication)
Usually, disassembly problems only occur if:
¯ the connection is spinning due to overload or a too low friction factor and fretting
corrosion has occurred,
¯ the shrink disc has been tightened too much leading to a plastic deformation of
components,
¯ the components are corroded.

4.4.7 Foot mounting
The foot on the g500−S130 S660 gearboxes can be mounted in three positions (3, 4,
5) using the supplied screws. It is mounted on side 6 using 4 screws and additionally on
side 1 using 2 screws. The screws must be mounted according to the hole pattern on the
foot (see figure) depending on the foot position.
Mounting order: depending on the mounting situation and installation space, the foot
can first be screwed to the machine housing and then to the gearbox or vice versa. The
foot can be mounted to the machine using studs or screws (not included in the scope of
supply).
EN
Aligning the gearbox with the foot: independent of the mounting order, the gearbox
must be aligned with the machine shaft.

¯ Take safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
6.2 Before switching on
Please check:
¯ Drive function - machine function assignment
¯ The direction of rotation of the drive shaft

7.1 Important notes
Note!
¯ Gearboxes below 200 Nm are lubricated for life.
¯ The mechanical power transmission system is maintenance−free.
7.2 Maintenance intervals
¯ In case of gearboxes > 200 Nm, the lubricant must regularly be replaced.
– The type of lubricant is indicated on the nameplate. Replace the lubricant only
with the same type of lubricant.
– The lubricant maintenance interval depends on the lubricant temperature, see
Fig. 9.
