Working Principle<\/h2>\n

\"EVER<\/p>\n

Inside the sealed, oil-bath lubricated housing of the EP-SC404, four cascading planetary stages convert the high-speed, low-torque motor input into a reduced-speed, high-torque output at the driven shaft. A floating sun gear arrangement<\/strong> between stages automatically centres the load distribution across all planet gear contacts, compensating for minor alignment errors between the motor shaft and the driven machine. This self-centering feature extends planet bearing life in long-service installations where perfect alignment cannot always be guaranteed.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
► 4,000 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 SC404 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

Planet gears use 17CrNiMo6 carburised and profile-ground steel<\/strong>, providing superior fatigue life versus 20CrMnTi at equivalent case depth. Carburising is controlled to 0.8-1.1 mm with a core hardness of 30-38 HRC for impact resistance. The ring gear is 42CrMo4 through-hardened<\/strong> and bore-ground after hardening for dimensional stability. The planet carrier is a single-piece forged nodular iron construction<\/strong>, eliminating the flex found in welded split-type carriers. Output shaft seals are double-lip FKM<\/strong> for long life in synthetic oil service.<\/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 IP65 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
