EP-RPR2320 Planetary Gearbox<\/h1>\n

EVER POWER 2-Stage High-Torque Planetary Gearbox for Heavy Process Drives<\/p>\n

The EP-RPR2320<\/strong> enters the heavy process drive segment with 32,500 Nm<\/strong> 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<\/strong>, this unit maximises power transmission efficiency in high-power continuous-duty applications where energy operating costs dominate the total cost of ownership.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Two large-module planetary stages operate at high torque and moderate speed. The precision-forged one-piece sun gear shaft<\/strong> 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<\/strong> on the input housing flange accepts standard slip-type torque limiters for overload protection of the driven machine.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
▲ Integral Forged Sun Shaft<\/strong>
No coupling joint ?? eliminates the most common failure mode in reversing-torque applications.<\/div>\n<\/td>\n
\n
▲ Torque Limiter Interface Boss<\/strong>
Standard overload protection interface for downstream machinery protection.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ GGG70 Maximum-Grade Housing<\/strong>
Highest stiffness cast iron ?? resists deflection under large-module gear forces.<\/div>\n<\/td>\n
\n
▲ 42CrMo4 Ring Gears<\/strong>
Through-hardened ring gear for maximum surface hardness and wear resistance.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ Direct RPR2320 Replacement<\/strong>
Matching external dimensions ?? direct retrofit.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

Sun gear shafts are precision-forged from 42CrMo4 through-hardened steel<\/strong> ?? integral forging provides better fatigue life than separate shaft-and-gear assemblies. Planet gears use 18CrNiMo7-6 carburised<\/strong> steel, ground to DIN 5. Ring gears are 42CrMo4 through-hardened and bore-ground<\/strong>. Housing material is GGG70 nodular iron<\/strong> for maximum stiffness under large-module gear loading.<\/p>\n

Typical Application Scenarios<\/h2>\n\n\n\n\n\n\n\n\n
Industry<\/th>\nApplication<\/th>\nKey Requirement<\/th>\n<\/tr>\n<\/thead>\n
Extrusion<\/td>\nExtruder main drive, plastics processing<\/td>\nIntegral forged sun shaft handles reversing torque loads during die change.<\/td>\n<\/tr>\n
Cement<\/td>\nScrew conveyor head drive, raw meal<\/td>\nHigh-torque 2-stage drives large diameter auger at low RPM.<\/td>\n<\/tr>\n
Chemical<\/td>\nHeavy mixer main drive, viscous products<\/td>\n32,500 Nm handles startup torque of thick-product mixing at full load.<\/td>\n<\/tr>\n
HVAC<\/td>\nLarge axial fan main drive, power station<\/td>\n2-stage efficiency minimises fan house heat load in constrained enclosure.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Selection Guide<\/h2>\n
    \n
  1. Required Output Torque (Nm)<\/strong> ?? Confirm peak and continuous torque requirement with appropriate safety factor.<\/li>\n
  2. Gear Ratio<\/strong> ?? Motor speed (rpm) divided by required output speed (rpm).<\/li>\n
  3. Duty Cycle<\/strong> ?? Continuous S1 or intermittent S3\/S6; affects thermal de-rating.<\/li>\n
  4. Motor Interface<\/strong> ?? Flange type (SAE\/ISO), shaft diameter, keyway or spline specification.<\/li>\n
  5. Environment<\/strong> ?? IP class, ambient temperature, corrosion zone, orientation.<\/li>\n<\/ol>\n
