EP-RPR3150 Planetary Gearbox<\/h1>\n

EVER POWER 3-Stage 25,000 Nm Planetary Gearbox for Heavy Industrial Drives<\/p>\n

The EP-RPR3150<\/strong> triples the stage count of the RPR150 series to deliver 25,000 Nm<\/strong> output torque with a very wide ratio selection up to 160:1<\/strong>. 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<\/strong> where high torque and slow output speed are simultaneously required.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

The 3-stage arrangement provides cascading torque multiplication. The large-diameter ring gear<\/strong> 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<\/strong> provides triple-layer protection against slurry and dust ingress at the output shaft.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
◼ 160:1 Ultra-High Ratio<\/strong>
3-stage provides very slow output from standard motors ?? no additional reduction needed.<\/div>\n<\/td>\n
\n
◼ Wide-Face Third Stage Ring<\/strong>
Distributes high output torque across larger tooth area ?? reduces face wear.<\/div>\n<\/td>\n<\/tr>\n
\n
◼ Lip + Labyrinth Seal<\/strong>
Triple output shaft protection against slurry, swarf and dust in harsh environments.<\/div>\n<\/td>\n
\n
◼ 25,000 Nm High Torque<\/strong>
Handles large belt conveyor and marine winch applications directly.<\/div>\n<\/td>\n<\/tr>\n
\n
◼ Direct RPR3150 Replacement<\/strong>
Same flange and output dimensions as original Brevini unit.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

Third-stage ring gear is manufactured from 42CrMo4 through-hardened steel<\/strong> for maximum ring gear stiffness at large diameter. Planet gears use 17CrNiMo6 carburised<\/strong> 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 epoxy primer + polyurethane topcoat<\/strong>, 500-hour salt spray.<\/p>\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
