EP-RPR2250 Planetary Gearbox<\/h1>\n

EVER POWER Heavy-Duty 2-Stage Planetary Gearbox for High-Efficiency Industrial Drives<\/p>\n

The EP-RPR2250<\/strong> delivers 25,500 Nm<\/strong> in a 2-stage layout, engineered to replace the Brevini riduttori RPR2250. Its 2-stage design provides the best efficiency figure in the RPR250 size class ?? important for energy-intensive applications such as cement mill drives, large fan drives, pump drives and heavy machine tool main spindles<\/strong> where electrical energy cost over the product life significantly exceeds the purchase price.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Two large-module planetary stages handle the high input torque from primary motors rated up to several hundred kilowatts. The forged planet carrier<\/strong> in each stage is a single-piece construction ?? avoiding welded split-type carriers that can flex under peak loads and cause uneven planet load distribution. A thermal monitoring boss<\/strong> on the housing allows a PT100 probe to be fitted for oil temperature surveillance in energy-intensive continuous duty installations.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
● High Efficiency 2-Stage<\/strong>
Minimum energy loss ?? critical for high-power continuous-duty installations.<\/div>\n<\/td>\n
\n
● Forged One-Piece Carrier<\/strong>
No weld-line flex ?? even planet loading under peak torque.<\/div>\n<\/td>\n<\/tr>\n
\n
● Thermal Monitoring Boss<\/strong>
PT100 probe port for DCS integration and oil temperature trending.<\/div>\n<\/td>\n
\n
● GGG70 High-Grade Housing<\/strong>
Maximum stiffness for large-module gear loading in heavy-duty installations.<\/div>\n<\/td>\n<\/tr>\n
\n
● Marine C4 Epoxy Coating<\/strong>
Outdoor and industrial environment corrosion protection.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

All gears are forged from 18CrNiMo7-6 alloy steel<\/strong>, vacuum-degassed, carburised to 1.0-1.3 mm and ground to DIN 5. The ring gear is press-fitted into a GGG70 nodular iron housing<\/strong> ?? the highest iron grade in EVER POWER’s housing series ?? providing maximum stiffness for large module gear loading. External coating is marine epoxy C4 standard<\/strong> for outdoor and factory floor environments.<\/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
Cement<\/td>\nCement raw mill drive<\/td>\nHigh continuous power; thermal monitoring boss allows integration with mill DCS.<\/td>\n<\/tr>\n
HVAC<\/td>\nLarge centrifugal fan main drive<\/td>\n2-stage high efficiency reduces fan house energy consumption.<\/td>\n<\/tr>\n
Water<\/td>\nLarge vertical pump drive<\/td>\nAny-axis mounting allows direct coupling to vertical pump shaft without bevel gear.<\/td>\n<\/tr>\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
