Planetary gears

Exploded drawing PM 72
Mode of function
As the name says: planetary gears (PLGs)
function like planets. The sun wheel in thecenter is driven by the motor, transferring
its movement to three circumferential
planetary gear wheels which form a stage.
They are arranged on the axles of aplanetary carrier. The last planetary carrier
is integral to the drive shaft and so assures
the power transmission to the output. The
planetary gears are running within the gear
housing, which is called the outer ring gear.

Properties
Input and output are arranged coaxially.
The shafts turn in the same direction.
PLGs are suitable for cw and ccw rotation,
alternating, continuous and intermittent
operation and have an extremely high degreeof efficiency. Compared with other gear
designs, the compactness of PLGs offers
high performance density and high torquetransmission in the smallest of spaces.

Backlash
The backlash at the output side is increasing
based on adding the tolerances fromthe 1st to the 3rd stage. The maximum
backlash has to be mentioned.
Ball bearing
Limited through assembly conditions;the installation of the ball bearings in
the output flange is designed for a fixedbearing compared to the loose bearing
on the output shaft. Per your requirementa different design can be conducted.
Connecting flangeThis is where the PLG's flexibility really shows.
The planetary gear drives of IMS Gear canbe adapted to any (!) motor, with individual options on the input and output side.
Contact us with your specific requirements.
Delivery
IMS Gear Planetary Gears delivers units fully
assembled and tested with the motor ofyour choice, or individually with motor
pinion for assembly at your premises. We’dbe pleased to assist you in selecting the
motor.
Efficiency
The gearing efficiency takes accountof the rolling motion of the toothed gear,
whereas the gear efficiency accounts
for all the losses of the entire bearing.
This is why we always specify the gear
efficiency which is necessarily lower than
the gearing efficiency. As there are nostandardized measurement methods,
particular attention is called for whencomparing the efficiency specified bydifferent manufacturers.
Gear backlash
Gear backlash depends on a large numberof factors: type of load, number of stages,
bearing, design or material combination.
When comparing different manufacturers,
please note that there are also no standardized measurement methods. The values
specified in this catalogue were measured
with no load and with blocked input drive.
Heat treatment
The structural transformation taking
place when hardening the individual
metal components has a positive effecton the strength and the wear resistanceof the gear. IMS Gear has its own heat
treatment facility. Since we also have theentire metal machining activity in-house,
we are free to choose from a variety ofdifferent heat-treatable steel grades.

Installation position
Due to grease lubrication and the various
types of seals, the planetary gear drives of
IMS Gear can be installed in any desired
position.

Operating dynamics
High operational dynamics is achieved
with low moments of inertia, ease of
running and low wear and tear. Wherever
it makes sense, IMS Gear Planetary Gears
uses plastic instead of metal for theplanetary gears and arranges these ina well-balanced 120° angle array which,in turn, results in low moments of inertia.
We achieve ease of running with highgrade needle bearings or favorable friction
values between metal and plastic, lowwear through a special gearing designfor optimum rotational performance andby using plastic wheels. The typical IMS
Gear material mix guarantees excellent
operational dynamics (q.v. ball bearing).

Low-noise gears
Achieving the optimum acoustic
performance makes higher demands interms of true running and axial runout of
the motor bearing plate, flange and shaft.
The helical gearing causes axial forces toact on the motor shaft bearing. Adequate
dimensioning of the motor shaft bearing
must therefore be guaranteed. To counterthe grease-conveying effect of the helicalgearing, radial shaft O-rings or sealed
motor bearings are the first choice.

Operating factor CB
The mentioned operating factor CB=1.0
in the catalogue relates to constantdirection of rotation, no shock load anda daily operating time of 3 hours.

Lubrication
Our PLGs are lubricated with grease
and therefore maintenance-free during
their useful service life. Depending on
requirements, we select the best possible
lubricant from a choice of ten different
options.

Operating temperature
The operation temperature range
depends on material selection and choiceof lubricant. The temperature range of ourMounting position of gear drive
If the output shaft faces vertical additional
sealing methods can be implemented per
your requirement.

all metal versions with standard lubrication
is between –30 und +140 °C, the plastic
PK series between –15 and +65 °C.
Output shaft loads
As different manufacturers also use different
measuring methods, a comparison isdifficult and requires some attention. We'dbe pleased to calculate the maximum axial
and radial load including all parameters foryour specific application. Certain design
options also allow higher stress loads.
Output torque
The most important factor when selecting
a planetary gear drive is the output torque.
The gear reduction reduces the relatively
high motor speed to a lower output drive
speed, which increases the output torquein inverse ratio.
Overload torque
The maximum overload torque (impactload) is defined as the brief moment in time
during which the admissible output torqueis exceeded, e.g. when the motor runs up.
Peak load equals overload in plastic PLGs,
whereas the overload torque can be as

much as 1.5 times the peak load in metalplastic combinations or all metal versions.
Reduction ratios
Changing the number of teeth of thesun gear and the planet gears allows
different reduction ratios per each stage.
IMS Gear Planetary Gears combines
the reductions in as many as three stages
and so achieves a total of as many as
44 non-integer reduction ratios, allowing
an enormous variety of different gear
requirements to be realized.
Sealing modes
The protection categories are definedby DIN EN 60259. If requested, we also
supply output and motor side seals whichallow you to realize high protection
categories.
Service Life
Depending on ambient conditions andthe operational data of the drive system,
the useful service life of a PLG is between
200 and 15.000 hours. With the variety ofdifferent options in applications and use,
no generally valid statement can be givenon the useful service life.

The details given herein are recommended values. Minor variances due to reduction ratios or non-standard testing or measuring methods
etc. may occur. Please refer to pages 6 and 7 of this catalogue for basic or additional information, or contact us directly. Technical details
subject to change without notice.
