Gear unit with solid shaft
INFORMATION
If input and output elements are subject to the Directive 2014/34/EU, the input and
output elements require ATEX approval.
INFORMATION
Only use belts with sufficient electrical leakage resistance < 10

Assembling input and output elements
NOTICE
Damage to bearing, housing or shafts due to incorrect mounting
Possible damage to property.
•
Only use a mounting device for installing input and output elements (see chapter
"Using the mounting device" (→
)). Use the threaded centering bore at the
shaft end.
•
Never force belt pulleys, couplings, pinions, etc. onto the shaft end by hitting
them with a hammer.
•
During the installation of belt pulleys, make sure the belt is tensioned correctly in
accordance with the manufacturer's instructions.
•
Make sure the transmission elements are balanced after fitting and do not give
rise to any impermissible radial or axial forces. For the approved values, refer to
the catalog "Gearmotors" or "Explosion-Proof Drives".
INFORMATION
Mounting is easier if you first apply lubricant to the output element or heat it up briefly
to 80 – 100 °C.
