EP-RPR2320 Planetary Gearbox
EVER POWER 2-Stage High-Torque Planetary Gearbox for Heavy Process Drives
O EP-RPR2320 enters the heavy process drive segment with 32,500 Nm output torque from a compact 2-stage design, replacing the Brevini riduttori RPR2320. Designed for heavy process machinery, large screw conveyors, extruder main drives, heavy-duty mixer drives and large fan systems, this unit maximises power transmission efficiency in high-power continuous-duty applications where energy operating costs dominate the total cost of ownership.

Princípio de funcionamento
Two large-module planetary stages operate at high torque and moderate speed. The precision-forged one-piece sun gear shaft eliminates the coupling joint used in assembled sun shaft designs ?? a common failure point under reversing torque loads in extruder applications. A torque limiter interface boss on the input housing flange accepts standard slip-type torque limiters for overload protection of the driven machine.
Principais vantagens
|
▲ Integral Forged Sun Shaft
No coupling joint ?? eliminates the most common failure mode in reversing-torque applications. |
▲ Torque Limiter Interface Boss
Standard overload protection interface for downstream machinery protection. |
|
▲ GGG70 Maximum-Grade Housing
Highest stiffness cast iron ?? resists deflection under large-module gear forces. |
▲ 42CrMo4 Ring Gears
Through-hardened ring gear for maximum surface hardness and wear resistance. |
|
▲ Direct RPR2320 Replacement
Matching external dimensions ?? direct retrofit. |
Tecnologia de Estrutura e Materiais
Sun gear shafts are precision-forged from 42CrMo4 through-hardened steel ?? integral forging provides better fatigue life than separate shaft-and-gear assemblies. Planet gears use 18CrNiMo7-6 carburised steel, ground to DIN 5. Ring gears are 42CrMo4 through-hardened and bore-ground. Housing material is GGG70 nodular iron for maximum stiffness under large-module gear loading.
Cenários típicos de aplicação
| Indústria | Aplicativo | Key Requirement |
|---|---|---|
| Extrusion | Extruder main drive, plastics processing | Integral forged sun shaft handles reversing torque loads during die change. |
| Cimento | Screw conveyor head drive, raw meal | High-torque 2-stage drives large diameter auger at low RPM. |
| Produtos químicos | Heavy mixer main drive, viscous products | 32,500 Nm handles startup torque of thick-product mixing at full load. |
| HVAC | Large axial fan main drive, power station | 2-stage efficiency minimises fan house heat load in constrained enclosure. |
Guia de Seleção
- Torque de saída necessário (Nm) ?? Confirm peak and continuous torque requirement with appropriate safety factor.
- Relação de transmissão ?? Motor speed (rpm) divided by required output speed (rpm).
- Duty Cycle ?? Continuous S1 or intermittent S3/S6; affects thermal de-rating.
- Interface do motor ?? Flange type (SAE/ISO), shaft diameter, keyway or spline specification.
- Ambiente ?? IP class, ambient temperature, corrosion zone, orientation.

Case Studies ?? Engineer Field Notes
| País | Aplicativo | Opinião |
|---|---|---|
| Alemanha | Extruder main drive replacement, plastics plant | “Integral forged sun shaft solved the recurring failure at the coupling joint we experienced every 8,000 hours with the previous assembled design. 18 months and no failure.” ?? Plant Engineer, Frankfurt. |
| Índia | Large screw conveyor, cement raw meal handling | “32,500 Nm handled the startup torque on our compacted meal auger without triggering the overload protection ?? something our previous 28,000 Nm unit could not manage.” ?? Process Engineer, Mumbai. |
| USA | Large axial fan, combined cycle power station | “2-stage efficiency was verified at 97.6% at rated load on our test rig. Within 0.1% of EVER POWER’s published data.” ?? Commissioning Engineer, Houston. |
Perguntas frequentes
Q: What torque limiter types are compatible with the input boss?
A: The boss is dimensioned for standard friction-plate and shear-pin type torque limiters. Provide your torque limiter brand and model at order for dimensional confirmation.
Q: What is the reversing torque rating?
A: Rated output torque of 32,500 Nm applies equally in forward and reverse directions. Fatigue life assumes 50/50 direction split at rated torque.
