Description
EP-RPR3600 Planetary Gearbox
EVER POWER 3-Stage 98,000 Nm Ultra-Heavy Planetary Gearbox
Le EP-RPR3600 is one of EVER POWER’s most powerful RPR series gearboxes, achieving 98,000 Nm output torque with a 3-stage VAR-steel planetary design and ratio range extending to 250:1. Replacing the Brevini riduttori RPR3600, this unit is specified for the most demanding large-scale industrial installations — large cement raw mill and clinker mill main drives, large ship propulsion gearboxes, large slewing ring drive systems, sugar mill main drives and large industrial press drives.

Principe de fonctionnement
Three extra-large-module planetary stages operate with full oil-jet lubrication. The integrated oil cooling heat exchanger — a plate-type oil-to-water cooler built into the housing base — maintains oil temperature below 75 degC even at 98,000 Nm continuous duty in tropical ambient conditions. The output shaft arrangement uses a split-type shrink disc coupling interface for direct connection to large solid shafts without machining the driven shaft.
Principaux avantages
|
▲ 98,000 Nm Ultra-High Torque
One of the highest torque ratings in EVER POWER’s RPR product catalogue. |
▲ Integrated Oil-to-Water Cooler
Plate cooler built into housing base — maintains oil below 75 degC at tropical ambient. |
|
▲ Shrink Disc Coupling Interface
Direct connection to large solid shafts without shaft machining. |
▲ 316 SS Oil Cooler

Technologie des structures et des matériaux
All gears throughout three stages use 18CrNiMo7-6 VAR steel, ground to DIN ISO 1328 class 5. Planet carriers are massive GGG70 nodular iron forgings — not weldments — for maximum structural integrity. The integrated oil cooler body is 316 stainless steel for compatibility with cooling water from various sources including sea water if required.
Scénarios d'application typiques
| Industrie | Application | Exigence clé |
|---|---|---|
| Ciment | Large clinker mill main drive | 98,000 Nm sustained at 6,000+ annual hours — requires VAR + oil-to-water cooler. |
| Sucre | Sugar mill main crushing drive | 250:1 ratio drives crushing rolls at correct surface speed from large motor. |
| Marin | Large ship propulsion gearbox assist | Integrated oil cooler critical in engine room ambient temperatures up to 55 degC. |
| Press | Large industrial hydraulic press drive | 98,000 Nm peak torque on press down-stroke handled without overload. |
Guide de sélection
- Couple de sortie requis (Nm) — Confirm peak and continuous torque requirement with appropriate safety factor.
- Rapport de transmission — Motor speed (rpm) divided by required output speed (rpm).
- Cycle de service — Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Interface moteur — Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Environnement — IP class, ambient temperature, corrosion zone, orientation.

Études de cas — Notes de terrain d'ingénieur
| Pays | Application | Retour |
|---|---|---|
| Egypte | Cement clinker mill main drive, large plant | “Integrated oil cooler eliminated the external oil cooling unit we previously had on the mill platform. Space saving was significant. Oil temperature now stable at 68 degC even in summer.” — Plant Director, Cairo. |
| Cuba | Sugar mill main crushing drive, state refinery | “250:1 ratio allowed us to use our existing motor without replacement. Capital saving was decisive for our budget-constrained modernisation project.” — Technical Director, Havana. |
| Corée du Sud | Large marine propulsion gearbox assist | “316 SS oil cooler was required for sea water cooling circuit compatibility. EVER POWER confirmed this specification without additional cost.” — Marine Engineer, Ulsan. |
Foire aux questions
Q: What cooling water flow rate is required for the plate cooler?
A: Standard flow rate is 15-20 litres/minute at inlet temperature below 30 degC. Sea water service requires reduced flow rate — contact our engineering team for a cooling calculation.
Q: Is the shrink disc coupling included?
A: The shrink disc interface boss is standard. The shrink disc itself is sourced separately and matched to the customer’s shaft diameter — EVER POWER can supply or provide the coupling specification.
