If the clamping bolt [H
1
] is loosened too far or removed, the clamping ring [I] can rotate on the
clamping hub. Align it so that the clamping bolt [H
1
] is in the keyway of the clamping hub
(see table "Tbl-9").
For certain motor shaft diameters and applications, a slotted bushing needs to be installed in
addition.
For the version with
clamping bolt, eccentrical [H
1
]:
The slot of the bushing (if present) and the clamping hub must be flush with the groove
(if present) of the motor shaft; see Table "Tbl-9".
For the version with
clamping bolt, centrical [H
2
]:
The slots of the bushing (if present) and clamping hub have to be aligned with the keyway
(if present) of the motor shaft and rotated 90° from the clamping bolt, see Table "Tbl-9".
No gap is permitted between the motor [D] and the adapter plate [B].
Apply threadlocker (e. g. Loctite
®
243) to the four screws [F].
Fasten the motor [D] onto the adapter plate [B] with the four screws. Evenly tighten the screws
crosswise with increasing torque.
If the gearbox is a
single-stage gearbox (MF1)
, coat the clamping bolt [H] with threadlocker
(such as Loctite 243).
Tighten the clamping bolt [H] of the clamping hub [C].
The value for the tightening torque can also be found in Chapter 10.1 "Specifications for
mounting to a motor".
Screw the
locking screw
[A] into the adapter plate [B].
For screw size and specified tightening torque, see Table "Tbl-10".
5.4
Mounting the gearbox on a machine
Center the gearbox in the machine bed.
Apply threadlocker (e. g. Loctite
®
243) to the fastening screws.
