Working Principle<\/h2>\n

\"EVER<\/p>\n

EP-SL3504 uses a coaxial drive arrangement<\/strong> where motor input shaft and output shaft share the same centreline, providing maximum torque transmission efficiency with minimum installation footprint. The four-stage planetary architecture achieves approximately 35,000 Nm output torque<\/strong> from a compact sealed housing. Oil-bath lubrication<\/strong> maintains a continuous lubricant film on all gear contacts regardless of mounting orientation \u2014 horizontal, vertical or inverted \u2014 making this unit suitable for the full range of industrial machine configurations encountered in conveyor, mixer, agitator and rotating equipment drives.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n
\n
◼ 35,000 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 SL3504 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
<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

All gear stages use 17CrNiMo6 case-hardening steel<\/strong> manufactured to vacuum-degassing standards for superior core impact toughness. The output shaft is 42CrMo4 through-hardened<\/strong>, providing high bending stiffness for cantilevered coupling loads. A thermal monitoring boss<\/strong> (G1\/4 threaded) is standard on all units with torque rating above 12,000 Nm, allowing a PT100 temperature probe to be fitted for plant DCS integration. External surfaces receive a marine-grade C4 epoxy coating<\/strong> system for outdoor and marine auxiliary applications.<\/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
