EP-RPR2046 Planetary Gearbox<\/h1>\n

EVER POWER Compact 2-Stage Planetary Gearbox for Light Industrial Automation<\/p>\n

The EP-RPR2046<\/strong> is EVER POWER’s lightest RPR series planetary gearbox, engineered as a direct replacement for the Brevini riduttori RPR2046. At 4,600 Nm<\/strong> and only 18 kg, it serves industrial automation, packaging machinery, conveyor drives and light robotic articulation<\/strong> where space, weight and positioning accuracy are the primary design constraints.<\/p>\n

Working Principle<\/h2>\n

\"EVER<\/p>\n

Input torque enters via the motor flange and drives a first-stage sun gear. Planet gears orbit the sun and react against a fixed ring gear, multiplying torque at the first-stage carrier. The carrier becomes the second-stage input, providing cumulative ratio up to 60:1. The needle-roller planet journals<\/strong> maintain precise planet positioning at high input speeds, critical for servo-motor compatibility.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
● Lightweight 18 kg<\/strong>
Aluminium housing option keeps vehicle and machine weight minimal.<\/div>\n<\/td>\n
\n
● 4,000 rpm Input<\/strong>
High input speed compatibility for servo and high-speed induction motors.<\/div>\n<\/td>\n<\/tr>\n
\n
● Low Backlash<\/strong>
Needle-roller planet journals minimise backlash for precise servo positioning.<\/div>\n<\/td>\n
\n
● IP65 Sealing<\/strong>
Dust-tight and splash-proof for indoor automation environments.<\/div>\n<\/td>\n<\/tr>\n
\n
● Direct RPR2046 Fit<\/strong>
Same flange and output bore ?? no machine modification at retrofit.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

Housing cast from ADC12 aluminium alloy<\/strong> for minimum weight. Planet gears use 20CrMnTi steel<\/strong> carburised to 0.6-0.8 mm, ground to DIN 6 accuracy. All seals are NBR compound<\/strong> for synthetic and mineral gear oil compatibility.<\/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
