EP-RPR3250 Planetary Gearbox
EVER POWER 3-Stage 42,000 Nm Planetary Gearbox with Ultra-High Ratio
El EP-RPR3250 raises output torque to 42,000 Nm and extends ratio coverage to 200:1 by adding a third stage to the RPR250 housing. Replacing the Brevini riduttori RPR3250, this unit covers the most demanding segment of the RPR250 size class ?? slow-speed heavy crane drives, large offshore mooring winch main drives, heavy mixer main drives and industrial kiln drives where very high torque and very slow output speed are simultaneously required.

Principio de funcionamiento
The 3-stage architecture provides a cumulative 200:1 ratio from a single housing. The 4-planet output carrier distributes final stage torque across four simultaneous contact points rather than the standard three, reducing per-tooth stress by 25% at 42,000 Nm. A dual lip seal with intermediate grease pocket at the output shaft provides redundant sealing against the high-viscosity gear oils used at this torque class.
Ventajas principales
|
▲ 200:1 Ultra-High Ratio
Single housing replaces tandem gearbox arrangements for extreme reduction ratios. |
▲ 4-Planet Output Stage
25% lower tooth stress ?? extended fatigue life under repeated peak loads. |
|
▲ VAR Steel Output Stage
Aircraft-grade steel in output gears ?? maximum fatigue life at 42,000 Nm. |
▲ Dual Lip + Grease Pocket
Redundant output shaft sealing for long seal life with high-viscosity oils. |
|
▲ Direct RPR3250 Replacement
Same flange and port layout. |
Estructura y tecnología de materiales
Output stage planet gears use Acero refundido por arco al vacío (VAR) 18CrNiMo7-6 ?? the highest available grade ?? for maximum fatigue life at 42,000 Nm. Housing is Hierro nodular GGG70 with shot-peened bore zones for improved fatigue resistance. External coating is C5M marine epoxy (720-hour salt spray) for offshore and coastal installations.
Escenarios de aplicación típicos
| Industria | Solicitud | Requisito clave |
|---|---|---|
| Grúa | Heavy slewing crane main travel drive | 200:1 ratio allows low-speed precise positioning with standard large hydraulic motor. |
| Costa afuera | Mooring winch main drive | 4-planet output stage handles repeated peak mooring loads without tooth damage. |
| Industrial | Large industrial kiln drive | Very slow rotation (1-3 rpm) of multi-tonne kiln shell requires 200:1 ratio. |
| Mixing | Large industrial agitator | 42,000 Nm handles thick material mixing without stall at startup. |

Estudios de caso ?? Notas de campo del ingeniero
| País | Solicitud | Comentario |
|---|---|---|
| Emiratos Árabes Unidos | Heavy slewing crane main drive, construction port | “200:1 ratio in a single housing eliminated the two-stage gearbox arrangement we had before. Space saving on the crane deck was considerable.” ?? Project Engineer, Abu Dhabi. |
| Norway | Offshore mooring winch, PSV conversion | “4-planet output stage has handled repeated peak mooring loads that destroyed our previous 3-planet unit. 14 months and counting with no failures.” ?? Chief Engineer, Bergen. |
| Alemania | Large industrial kiln drive, cement plant | “VAR steel documentation was required by our process insurance auditor. EVER POWER provided the full melt certificate within 5 days.” ?? Technical Manager, Dusseldorf. |
Preguntas frecuentes
Q: Can a standard 3-planet output stage be specified to reduce cost?
A: Yes. A standard 3-planet output variant is available at reduced cost ?? recommended for intermittent duty applications where peak torque is less frequent.
Q: Is the VAR steel documentation available for third-party audits?
A: Yes. Full melt traceability certificates are provided with every EP-RPR3250 as standard.
