Introduction
Technical information

Overview
(continued)
Planetary stages
Describes the gear stages between the input drive assembly
and the low speed shaft (LSS).
Input drive assembly
The input drive assembly comprises a SIMOGEAR geared motor
or a SIMOGEAR gear unit with adapter.
LSS (Low Speed Shaft)
Describes the low speed shaft of the planetary gear unit or
planetary geared motor.
This is generally the output shaft of the gear unit.
HSS (High Speed Shaft)
Describes the high speed shaft of the planetary gear unit or
planetary geared motor.
This is generally the input shaft of the gear unit.
Paint finish
FLENDER SIP planetary gear units/geared motors are painted
as standard in color RAL 5015 (sky blue). Guards and protection
devices are coated in the warning color RAL 1003
(signal yellow).
For further information about colors and the paint system,
please refer to chapter "Options for operation".
Seals
The input shaft and output shaft are sealed as standard with
radial shaft seals. The seal material is adapted to satisfy a wide
range of requirements such as resistance to low temperatures
and PG oil.
For special purposes, refillable labyrinth seals (taconite) are
available.
Cooling
The units are cooled via radiation and convection from the
housing surface up to the thermal capacity specified in chapter
"Configuration".
Additional cooling options may be available on request.
Weights, dimensions
The specified weights are average values; illustrations and
dimensions are not binding. Siemens reserves the right to make
technical changes in the context of further technical develop-
ment.
Noise behavior
SIP planetary geared motors have noise levels below the per-
missible noise limits defined for gear units in VDI Guideline 2159
and for motors in IEC 60034-9.
The associated values are listed in Operating Instructions
BA 9300.
Efficiency classes
The motors integrated in FLENDER SIP planetary geared motors
comply with international standard IEC 60034-30:2008 and are
available in efficiency classes IE1, IE2 and IE3. Further informa-
tion can be found in the SIMOGEAR Catalog MD 50.1.
Environmental conditions
FLENDER SIP are designed for indoor and outdoor operation
under a wide variety of environmental conditions.
The range of permissible ambient temperature is:
-20 °C
t
U
40 °C (optionally down to -40 °C). Please contact
the manufacturer if products are to be operated at higher or
lower ambient temperatures than those specified above
because components (such as seals) need to be adapted.
The bolted connections must be tightened at ambient tempera-
tures above -20 °C.
Please notify the manufacturer about environmental influences
such as saltwater, salty air, corrosive substances, dust, mud,
rockfall, excess pressure, extreme vibration or extreme shock,
as these factors need to be taken into account in the design.
Preservation
FLENDER SIP planetary gear units
The internal preservation is dependent on the oil used.
For planetary gear units with corrosion prevention, the following
storage times are possible:
If the storage periods mentioned are exceeded, the anti-corro-
sive agent in the planetary gear unit must be renewed.
The externally protruding shaft ends and machined surfaces are
also preserved.
SIMOGEAR geared motors
L
Gear units/geared motors that are protected by a long-term
preservation agent must not be opened before they are commis-
sioned or else the VCI corrosion inhibitor will vaporize. The oil
level must be checked before commissioning. It is recom-
mended that gear units/geared motors are stored in the position
in which they will be mounted.
For further information about storage and preservation, please
refer to the SIMOGEAR Catalog MD 50.1 and the Operating
Instructions BA 2030.
The externally protruding shaft ends and machined surfaces are
also preserved.
Maintenance
Compliance with the conditions for operation and installation is
essential. To prevent damage to the gear unit or failure of the
drive, regular inspection and maintenance must be performed
as specified in the operating instructions.
Delivery
FLENDER SIP gear units are delivered preassembled and ready
to install and are shipped with oil as standard. Shipment without
oil can be selected as an option.
The planetary gear units/geared motors are also preserved and
coated according to the selected order code for corrosion pro-
tection.
Attachment parts such as optional torque arms and shrink disks
are supplied loose.
1)
Only if mineral oil or synthetic PAO-based oil is used.
2)
Only if synthetic PG-based oil is used. Further information is available on request.
3)
A VCI (volatile corrosion inhibitor) is added to the gear unit oil.
