function.
•
Handle the VLT
®
OneGearDrive with care and do
not place it on any rough surfaces.
2.4 Mounting Arrangement
CAUTION
Depending on the reduction ratio, geared motors develop
substantially higher torques and forces than high-speed
motors of similar power.
Mounts, substructure and torque restraint must be rated
for the high forces anticipated during operation and
secured sufficiently against loosening. Cover the output
shaft(s) and any second motor shaft extension present, as
well as the transmission elements mounted on it
(couplings, chain wheels etc.), so that they cannot be
touched.
Install the drive unit as free from vibration as possible.
Observe the special instructions for installation locations
with abnormal operating conditions (e.g. high ambient
temperatures above 40
°
C). The fresh air intake must not
be restricted by unsuitable installation or by fouling.
Commercially available slip clutches are recommended if
there is a risk of blocking.
Take care when fitting transmission elements onto the
hollow shaft of the gear unit, which is finished to ISO H 7.
Use the tapped end hole intended for this purpose
according to DIN 332 if possible.
2.4.1 Mounting Procedure
1.
Fasten the drive unit by its flange.
2.
Attach the gear units with hollow shafts on to
the driven shaft using the means provided.
