EP-RPR3046 Planetary Gearbox<\/h1>\n

EVER POWER 3-Stage Compact Planetary Gearbox ?? Higher Reduction for Automation<\/p>\n

The EP-RPR3046<\/strong> adds a third planetary stage to the RPR046 housing, raising peak output torque to 7,800 Nm<\/strong> and ratio range to 100:1 while maintaining the same external footprint as the 2-stage RPR2046. This makes it the first choice when servo or induction motors need a high reduction ratio ?? such as slow-speed rotary tables, indexing mechanisms and material handling lifts ?? without enlarging the machine frame.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Three sequential planetary stages share the same concentric axis. Stage 1 handles the high-speed motor input at up to 3,500 rpm. Stage 2 and 3 multiply torque further with each reducing input speed proportionally. The floating sun gear<\/strong> in stage 2 compensates for carrier concentricity errors between stages, eliminating the need for precision alignment at assembly and improving load sharing across all planet gears simultaneously.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
▲ 100:1 High Ratio<\/strong>
3-stage design covers slow-speed applications that a 2-stage cannot reach.<\/div>\n<\/td>\n
\n
▲ Same Footprint as RPR2046<\/strong>
No machine redesign needed when upgrading from 2-stage to 3-stage.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ Floating Sun Stage 2<\/strong>
Compensates inter-stage concentricity, improving load sharing and life.<\/div>\n<\/td>\n
\n
▲ Angular Contact Output<\/strong>
Handles combined axial and radial loads from cantilevered drive elements.<\/div>\n<\/td>\n<\/tr>\n
\n
▲ Direct RPR3046 Replacement<\/strong>
Identical flange dimensions ?? bolt-in replacement.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

The 3-stage housing is cast from GGG40 ductile iron<\/strong> for stiffness. Planet gears throughout all three stages use 17CrNiMo6 steel<\/strong>, carburised and ground to DIN 5 accuracy. Angular contact ball bearings<\/strong> support the output shaft, providing combined axial and radial load capacity for cantilevered gear or sprocket loads.<\/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
