Mounting Positions Any mounting position is permissible.

Lubrication The PLS gearboxes are lubricated for life with high grade semi-fluid synthetic grease “Klubersynth GE 46-1200” . (Kluber Lubrication LP, - www.klueber.com -). Under normal operating conditions it is not required to change or replen-ish the lubricant. Since the NEUGART gears are honed, no run in wear occurs, there is no lubricant contamination from the wear particles during the run in period. For special requirements such as extreme high or low temperatures, USDA food grade lubricants etc., please contact Neugart USA.

Operating Temperature Temperature range is –25 to +100 degree C (-13F to 212F). Consult Neugart USA if the operating temperatures are outside this range.

Recommended Motor Flange / Motor shaft run out tolerances The Motor shaft run out and flange perpendicularity should be according to DIN 42955-R tolerances to avoid unneces-sary bearing loads and associated heat build up along with possible premature bearing wear. (visit www.neugartusa.com — >service —>FAQ, for the detailed specifications of the DIN 42955-R tolerance )

Shaft Seals Premium NBR shaft seals are used in the PLS planetary servo gearboxes. We recommend inspecting the seal after a maximum of 10,000 hrs operation. Optional VITON or Teflon based seals upon request.

Protection class The enclosure protection class of the PLS planetary servo gearboxes corresponds to class IP 65.

Lubrication PLS-HP gearboxes are lubricated for life with high grade semi fluid synthetic grease “Klubersynth GE 46-1200” . (Kluber Lubrication LP, - www.klueber.com -). Under normal operating conditions it is not required to change or replen-ish the lubricant. Since the NEUGART gears are honed, no run in wear occurs and consequently there is no lubricant contamination from the wear particles during the run in period. For extreme high or low temperatures, USDA food grade lubricants etc. please contact Neugart USA.



Shaft Seals Premium shaft seals suitable for elevated temperatures are used in the PLS-HP planetary servo gearboxes. We rec-ommend to inspect the seal after a maximum of 10,000 hrs operation.

Protection class The enclosure protection class of the PLS-HP planetary servo gearheads corresponds to class IP 65.

Lubrication PLF-HP gearboxes are lubricated for life with high grade semi fluid synthetic grease “Klubersynth GE 46-1200” . (Kluber Lubrication LP, - www.klueber.com -). Under normal operating conditions it is not required to change or replen-ish the lubricant. Since the NEUGART gears are honed, no run in wear occurs and consequently there is no lubricant contamination from the wear particles during the run in period. For extreme high or low temperatures, USDA food grade lubricants etc. please contact Neugart USA.


Operating Temperature Temperature range is –25C (-13F) to 110 C (232F). Consult Nugart if the operating temperatures are outside this range.

Recommended Motor Flange / Motor shaft run out tolerances The Motor shaft run out and flange perpendicularity should be according to DIN 42955-R tolerances to avoid unneces-sary bearing loads and associated heat build up along with possible premature bearing wear. (visit www.neugartusa.com - service -FAQ, for the detailed specifications of the DIN 42955-R tolerance )

Shaft Seals Premium shaft seals suitable for elevated temperatures are used in the PLF-HP planetary servo gearheards. We rec-ommend to inspect the seal after maximum of 10,000 hrs operation.

Protection class The enclosure protection of the PLF-HP planetary servo gearheads satisfies class IP 65 specifications.

Sizing / Selection of NEUGART Servo Gearheads

DEFINITION OF THE RATED TORQUE Torque rating of the NEUGART gearheads is in line with the applicable proven rating standards (AGMA, DIN, ISO). The listed rated torque of the gearheads is based on the endurance limit of the components (gears, shafts, car-rier, housing) which means the gearing will endure unlimited number of load cycles as long as the load torque does not exceed the gearhead rated torque.

1) Determine the required gearhead torque rating: For a reliable long gearhead operation life: TRGRT – Required Gearhead Torque Rating = TMAT - Max. Application Torque

TMAT - Max. Application Torque - is the highest torque load repeatedly occurring during a characteristic load cycle for the given application. If the number of the load cycles with the maximum torque is only a few thousand over the gearhead expected life and the duration of the max torque cycles is only a few seconds, the max application torque can exceed the gearhead rated torque.


The clear rating definition / rating practice allows an easy transparent and reliable gearhead sizing and selection based on the -Required Gearhead Torque Rating - TRGRT - Basic rule T N (Selected Gearhead Rating) ≥ TRGRT – Required Gearhead Torque Rating

Bearings are rated for a defined number of hrs L10 life at 100 rpm output shaft speed according the bearing rating standards. (In this definition the output shaft means the slow speed shaft.) L10 life rating: 20 000 hrs for: PLS, WPLS, PLS-HP, PLF-HP, single stage PLE and WPLE gearheads 10 000 hrs for: two and three stage PLE and WPLE gearheads

Frequently are the exact application data and the TMAT peak torque loading not known and a selected servo motor needs to be matched up with the suitable size gearhead. To determine TMAT and required gearhead rating TRGRT pro-ceed as follows:

A) - Selection for a specific servo motor - no other load and application related details are known

TRGRT = TMAT = TMpeakT x i B) - Selection for a specific servo motor - motor and load inertia and non-dynamic friction load are known.

TRGRT = TMAT = [ (TMpeak -TLR) x (1-k) + TLR ] x i

TRGRT -Required Gearbox Torque Rating; TMpeak -Motor Peak Torque; TN -Gearhead Rated Torque TL -Friction Load Torque at the output TLR = TL / i - Friction Load Torque at the input JM -Motor Rotor Inertia k -Inertia Parameter k = JM / (JLR + JM ) JLR -Reflected Load Inertia (JLR = JL / i2) ; i -Gearbox Ratio;


Sizing / Selection of NEUGART Servo Gearheads

2. Check Motor and Gearhead geometrical compatibility, output shaft loading, operation conditions

After Neugart servo gearhead size is selected based on the required gearhead torque rating TRGRT check: - check motor shaft diameter motor shaft diameter must not exceed maximum input pinion bore diameter of selected gearhead - check gearhead output shaft loading if substantial axial and/or radial loads are present in the application - check recommended maximum unsupported motor weight (support it, if required) - check max input speed, ambient (operating) temperature, required IP class

C) - Selection for application with known detailed load cycle information

C-1 - High duty cycle operation - multiple load cycles per minute and expected gearhead life more than 5000 Hrs: Apply Method B (see above)

C-2 - Low cycle operation - few cycles per hour, expected gearhead life below 500 Hrs: Submit detailed data to Neugart USA for sizing assistance.

The ratio of inertial match IMR = JLR / JM is closely related to the inertia factor k k= 1/ (IMR +1). For a fast assessment of the peak torque loading of the gearhead, as function of the inertia match and friction load in % of the motor peak torque, use the depicted curves ►

Gearhead L10 life calculation L actual = L10N x (TN / TEQ)3.3 x 100 / nEQ

TN -gearhead rated torque TEQ -mean Load (according bearing calculation standards) nEQ - mean output speed (according bearing calculation standards) L10N = 20 000 hrs for PLS, WPLS, PLS-HP PLF-HP and 1- stage PLE and WPLE units L10N = 10 000 hrs for 2 and 3 stage PLE and WPLE units

For a selected gearhead the L10 life can be determined by applying the following equation:

User friendly sizing / selection and life calculation programs are available at www.neugartusa.com - (► -service ► -calculation programs)

NOTE: the here recommended selection is based on controlled, defined acceleration and deceleration. If the application has fre-quent undefined shock or impact-loads (such as due to undefined jerk in the motion profile wit ) please consult NEUGART

CUSTOM GEARS Motor Integrated Gears


Motor Integrated Gears Majority of the modern machinery requires small size and light weight drives. The integration of a servo motor and a gear makes the assembly considerably more compact lighter. Over the years NEUGART has developed integrated solutions for a number of reputable motor manufacturers. These high quality and precision “custom-subassemblies” are manufactured to strict specifications and supplied the motor manufacturer for integration within the motor.

Comparison of a motor attached “bolt-on” gearhead

to a motor flange integrated solution. The integrated version is not only more compact, but the integrated gears have a higher torque rating and allow higher speeds than the “bolt-on” version
