Working Principle<\/h2>\n

\"EVER<\/p>\n

The four-stage epicyclic design of EP-SC1204 achieves maximum ratio range by stacking multiple reduction stages coaxially. Input power from the motor enters the first sun gear. The planet gears \u2014 mounted on a precision carrier \u2014 orbit the sun and react against a fixed ring gear<\/strong>, stepping down speed and multiplying torque at the carrier output. This carrier then drives the next stage input, compounding the reduction. The output shaft or hollow bore is supported by a back-to-back bearing arrangement<\/strong> providing combined axial and radial load capacity for direct sprocket, coupling or gear drive connections.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
★ 12,000 Nm Rated Torque<\/strong>
Full rated output torque for demanding continuous industrial duty cycles.<\/div>\n<\/td>\n
\n
► 4-stage Efficiency<\/strong>
Balanced efficiency and ratio range for the required application.<\/div>\n<\/td>\n<\/tr>\n
\n
● Brevini SC1204 Direct Fit<\/strong>
Identical mounting dimensions \u2014 installs in original machine pocket without modification.<\/div>\n<\/td>\n
\n
▲ Oil-Bath Lubrication<\/strong>
Sealed oil-bath serves all mounting orientations \u2014 horizontal, vertical and inverted.<\/div>\n<\/td>\n<\/tr>\n
\n
◆ 18-Month Warranty<\/strong>
EVER POWER’s 18-month warranty exceeds the 12-month standard of most European OEM suppliers.<\/div>\n<\/td>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

The one-piece GGG50 ductile iron housing<\/strong> is stress-relieved after casting and precision-bored to eliminate misalignment between gear stages. Planet journals run on needle roller bearing assemblies with hardened pins<\/strong>, providing maximum radial stiffness in the compact housing diameter. The output flange register face is precision-turned to 0.015 mm total runout<\/strong> for accurate shaft coupling or sprocket mounting without eccentricity. O-ring face seals at housing joint faces use HNBR compound<\/strong> for compatibility with biodegradable hydraulic fluids.<\/p>\n

Selection Guide<\/h2>\n
    \n
  1. Required Output Torque (Nm)<\/strong> \u2014 Confirm peak and continuous torque with safety factor of 1.3-2.0.<\/li>\n
  2. Gear Ratio<\/strong> \u2014 Motor speed (rpm) \/ required output speed (rpm). Range: 50:1 – 500:1.<\/li>\n
  3. Stage Count<\/strong> \u2014 4-stage provides ratio range 50:1 – 500:1. Higher stages = higher ratio and lower efficiency.<\/li>\n
  4. Motor Interface<\/strong> \u2014 Flange type (SAE \/ IEC metric), shaft diameter and keyway.<\/li>\n
  5. IP Rating<\/strong> \u2014 IP66 is standard. IP67\/IP68 upgrade available for washdown or outdoor service.<\/li>\n
  6. Mounting Orientation<\/strong> \u2014 Horizontal, vertical or inverted; all supported with standard oil-bath lubrication.<\/li>\n
  7. Operating Temperature<\/strong> \u2014 Standard -25 to +80 degC; Arctic and high-temp variants available.<\/li>\n<\/ol>\n
