EP-RPR2800 Planetary Gearbox
EVER POWER 2-Stage 82,000 Nm Extreme-Duty High-Efficiency Planetary Gearbox
De EP-RPR2800 is EVER POWER’s most powerful 2-stage RPR gearbox, delivering 82,000 Nm output torque from a 2-stage design that maximises power transmission efficiency at extreme torque. Replacing the Brevini riduttori RPR2800, this unit is the preferred choice for high-power continuous-duty applications where the efficiency advantage of 2-stage design outweighs the cost of the larger housing — large mine ventilation fan drives, ultra-large pump drives, heavy ship thruster drives and primary metal processing drives.

Arbetsprincip
Two extreme-large-module planetary stages handle up to 120 kW continuous input power. The active oil-jet lubrication with integrated oil cooler bypass valve allows the oil system to circulate warm oil through the bypass at startup — protecting bearings and gear contacts from cold oil viscosity stress before the oil reaches operating temperature. The output flange features a large-diameter precision register for accurate centering of large-bore coupling flanges without separate centering rings.
Kärnfördelar
|
◼ 82,000 Nm Extreme Torque
Most powerful 2-stage RPR gearbox in EVER POWER’s catalogue. |
◼ 2x VAR Steel — Highest Purity
Double vacuum-arc-remelted steel — maximum fatigue life at extreme continuous duty. |
|
◼ Cold-Start Oil Bypass Valve
Circulates warm oil to all contacts before cold oil reaches operating temperature. |
◼ ISO Class 4 Gear Accuracy
Highest accuracy option — minimum transmission error for large machine drives. |
|
◼ Direct RPR2800 Replacement
Same flange dimensions as original Brevini unit. |
Struktur och materialteknik
All gears use 18CrNiMo7-6 double vacuum-arc-remelted (2x VAR) steel — the highest available purity for the gear steel used in any EVER POWER product. Carburising depth is 1.3-1.6 mm; profiles ground to ISO 1328 class 4. Planet carriers are GGG70 heavy-section nodular iron forgings. The output shaft is a solid 42CrMo4 + 18CrNiMo7-6 composite forging for maximum bending stiffness.
Typiska tillämpningsscenarier
| Industri | Ansökan | Viktigt krav |
|---|---|---|
| Brytning | Ultra-large mine ventilation fan | 82,000 Nm allows direct drive of large fan impeller without belt stage. |
| Metal | Primary aluminium reduction cell stirrer | 2-stage efficiency critical for energy-intensive electrolytic reduction process. |
| Marin | Large thruster drive, heavy AHTS vessel | 2-stage minimises gearbox losses in tight engine room heat budget. |
| Water | Very large vertical turbine pump, hydroelectric plant | 82,000 Nm handles large turbine pump startup torque without soft-starter. |
Urvalsguide
- Erforderligt utgångsmoment (Nm) — Confirm peak and continuous torque requirement with appropriate safety factor.
- Utväxlingsförhållande — Motor speed (rpm) divided by required output speed (rpm).
- Driftscykel — Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Motorgränssnitt — Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Miljö — IP class, ambient temperature, corrosion zone, orientation.

Fallstudier — Fältanteckningar för ingenjörer
| Land | Ansökan | Feed-back |
|---|---|---|
| Australien | Ultra-large mine ventilation fan, deep coal mine | “82,000 Nm direct drive eliminated the belt transmission we previously used. Belt maintenance was a significant cost — now eliminated. Direct drive efficiency also measurably higher.” — Ventilation Engineer, Hunter Valley. |
| Iceland | Large geothermal pump drive, power plant | “2-stage efficiency was our primary requirement in a plant where every kWh has value. EVER POWER delivered 98.3% efficiency at rated load on our test certificate.” — Plant Engineer, Reykjavik. |
| Kanada | Large AHTS thruster drive replacement | “2x VAR documentation was required by our class surveyor. EVER POWER supplied within 3 days — faster than any European supplier we approached.” — Chief Engineer, Halifax. |
Vanliga frågor
Q: What is the maximum input speed for EP-RPR2800?
