EP-RPR3150 Planetary Gearbox
EVER POWER 3-Stage 25,000 Nm Planetary Gearbox for Heavy Industrial Drives
Der EP-RPR3150 triples the stage count of the RPR150 series to deliver 25,000 Nm output torque with a very wide ratio selection up to 160:1. As a direct replacement for Brevini riduttori RPR3150, this unit is specified for heavy conveyor head drives, marine winch assists, heavy-duty mixing equipment and large material handling systems where high torque and slow output speed are simultaneously required.

Funktionsprinzip

The 3-stage arrangement provides cascading torque multiplication. The large-diameter ring gear in the third stage is the key structural element ?? a wider ring gear face distributes the high output torque across a greater tooth contact area, preventing gear face wear under the heavy radial loads typical of large sprocket or chain drives. A lip seal and labyrinth combination provides triple-layer protection against slurry and dust ingress at the output shaft.
Kernvorteile
|
◼ 160:1 Ultra-High Ratio
3-stage provides very slow output from standard motors ?? no additional reduction needed. |
◼ Wide-Face Third Stage Ring
Distributes high output torque across larger tooth area ?? reduces face wear. |
|
◼ Lip + Labyrinth Seal
Triple output shaft protection against slurry, swarf and dust in harsh environments. |
◼ 25,000 Nm High Torque
Handles large belt conveyor and marine winch applications directly. |
|
◼ Direct RPR3150 Replacement
Same flange and output dimensions as original Brevini unit. |
Struktur- und Werkstofftechnologie

Third-stage ring gear is manufactured from 42CrMo4 durchgehärteter Stahl for maximum ring gear stiffness at large diameter. Planet gears use 17CrNiMo6 carburised steel ground to DIN 5 throughout all three stages. The output flange is machined to register diameter 0.02 mm TIR for accurate sprocket alignment. External coating is Epoxidgrundierung + Polyurethan-Decklack, 500-hour salt spray.
Typische Anwendungsszenarien
| Industrie | Anwendung | Hauptanforderung |
|---|---|---|
| Conveyor | Heavy belt conveyor head drive, 1.2 m belt | 160:1 ratio allows small motor to drive large belt system at correct belt speed. |
| Bergbau | Bucket elevator head drive | Slow steady output speed essential for bucket chain alignment and fill efficiency. |
| Marine | Mooring winch assist drive | 25,000 Nm handles large vessel mooring line pull without separate reduction stage. |
| Recycling | Industrial shredder infeed conveyor | Triple-layer seal protects against metal swarf and debris ingress. |
Auswahlhilfe
- Erforderliches Drehmoment (Nm) ?? Confirm peak and continuous torque requirement with appropriate safety factor.
- Übersetzungsverhältnis ?? Motor speed (rpm) divided by required output speed (rpm).
- Tastverhältnis ?? Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Motorschnittstelle ?? Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Umfeld ?? IP class, ambient temperature, corrosion zone, orientation.

Fallstudien? Ingenieur-Feldnotizen
| Land | Anwendung | Rückmeldung |
|---|---|---|
| Chile | Heavy belt conveyor, copper processing plant | “160:1 ratio let us use a standard 11 kW motor on our 1.2 m main conveyor. Previous solution required a 22 kW motor. Energy cost reduction was immediate.” ?? Electrical Engineer, Antofagasta. |
| Niederlande | Mooring winch assist, large container vessel | “25,000 Nm handled our peak mooring line tension without any sign of overload. 18-month warranty was key for our vessel class approval.” ?? Chief Engineer, Rotterdam. |
| Vereinigtes Königreich | Industrial shredder infeed, waste recycling facility | “Metal shrapnel and moisture in a shredder is hostile to seals. The lip plus labyrinth combination is the only reason this unit survived 12 months without seal replacement.” ?? Maintenance Manager, Sheffield. |
Häufig gestellte Fragen
Q: What is the rated static holding torque with no motor power?
A: The unit relies on the motor’s braking torque or an external brake for static holding. No internal holding brake is fitted as standard in this model. A brake adapter flange is available for external brake mounting.
Q: Can the ring gear be replaced in the field if worn?
A: Yes. The third-stage ring gear is a removable cartridge. Replacement requires removal of the end cover and is achievable by a qualified mechanic in approximately 4-6 hours.
