EP-RPR3255 Planetary Gearbox
EVER POWER 3-Stage 44,000 Nm Planetary Gearbox with Cooling Fin and High Ratio
The EP-RPR3255 combines the 3-stage torque capacity of the RPR255 series with the integrated cooling fin flange of the RPR2255, delivering 44,000 Nm at ratios up to 200:1 while maintaining safe oil temperatures in enclosed installations. Replacing Brevini riduttori RPR3255, this unit serves large marine gearrooms, large underground mining drives, enclosed offshore processing equipment and industrial furnace car drives.

काम के सिद्धांत
The 3-stage planetary train multiplies torque from input to output. The cooling fin flange on the output end bell dissipates frictional heat from the third stage, which operates at the highest torque ?? and therefore highest frictional losses ?? in the unit. A temperature bypass oil circulation groove channels hot oil from the third stage gear mesh zone past the fin flange before returning to the sump, maximising the cooling effect.
मुख्य लाभ
|
● Fin Flange + 3-Stage Torque
Best of both features ?? passive cooling AND maximum torque in one unit. |
● Oil Circulation Groove
Channels hot oil from third stage to fin flange ?? maximises cooling effect. |
|
● VAR Steel Third Stage
Maximum fatigue life at 44,000 Nm output torque. |
● 200:1 in Single Housing
Eliminates tandem gearbox in very high reduction enclosed installations. |
|
● Direct RPR3255 Replacement
Matching flange dimensions ?? direct retrofit. |
संरचना और सामग्री प्रौद्योगिकी
Third stage gears use 18CrNiMo7-6 VAR steel, carburised to 1.1-1.4 mm. The cooling fin end bell is ADC12 aluminium alloy, anodised for corrosion resistance in salt-air environments. Housing main body is GGG70 nodular iron. All output shaft seals are डबल-लिप एफकेएम rated for 130 degC continuous oil temperature.
विशिष्ट अनुप्रयोग परिदृश्य
| उद्योग | आवेदन | Key Requirement |
|---|---|---|
| अपतटीय | Large deck machinery enclosed gearroom | Fin flange manages heat in sealed gearroom without external cooling circuit. |
| खनन | Large underground ore crusher drive | 200:1 ratio + fin flange handles enclosed crusher drive in restricted tunnel space. |
| समुद्री | Large cargo vessel crane main drive | 44,000 Nm handles heavy lift crane main drive in enclosed crane house. |
| Furnace | Industrial furnace car track drive | Ultra-slow rotation of furnace car at high ambient temperature ?? fin flange essential. |
चयन मार्गदर्शिका
- आवश्यक आउटपुट टॉर्क (न्यूमीनियम मीटर) ?? Confirm peak and continuous torque requirement with appropriate safety factor.
- गियर अनुपात ?? Motor speed (rpm) divided by required output speed (rpm).
- साइकिल शुल्क ?? Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- मोटर इंटरफ़ेस ?? Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Environment ?? IP class, ambient temperature, corrosion zone, orientation.

| देश | आवेदन | प्रतिक्रिया |
|---|---|---|
| नॉर्वे | Large offshore deck crane gearroom, North Sea FPSO | “Sealed gearroom on an FPSO requires passive cooling. The oil circulation groove made the difference ?? oil temperature 15 degC lower than our previous unit.” ?? Mechanical Engineer, Stavanger. |
| Indonesia | Large underground ore crusher drive, nickel mine | “200:1 ratio in a sealed unit eliminated our previous tandem gearbox installation. Space saving was critical in the confined crusher chamber.” ?? Mine Engineer, Sulawesi. |
| दक्षिण कोरिया | Cargo vessel crane main drive, shipyard order, 6 units | “All 6 units installed without issue. CE documentation and unit test certificates were supplied with the delivery, satisfying our classification society requirements.” ?? Purchasing Manager, Busan. |
अक्सर पूछे जाने वाले प्रश्नों
Q: What maintenance does the oil circulation groove require?
A: No additional maintenance is needed. The groove is a passive channel ?? no pump or valve. Oil change intervals follow the standard schedule: first at 500 hours, then every 2,500 hours.
Q: Is the VAR steel upgrade available for stages 1 and 2 as well?
A: Yes, a full VAR steel build is available for all three stages upon request. This is recommended for extremely high-cycle or very high shock load applications.
