Working Principle
EP-SL1804 uses a coaxial drive arrangement 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 18,000 Nm output torque from a compact sealed housing. Oil-bath lubrication maintains a continuous lubricant film on all gear contacts regardless of mounting orientation — horizontal, vertical or inverted — making this unit suitable for the full range of industrial machine configurations encountered in conveyor, mixer, agitator and rotating equipment drives.
Core Advantages
|
◼ 18,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
★ 4-stage Efficiency
Balanced efficiency and ratio range for the required application. |
|
► Brevini SL1804 Direct Fit
Identical mounting dimensions — installs in original machine pocket without modification. |
● Oil-Bath Lubrication
Sealed oil-bath serves all mounting orientations — horizontal, vertical and inverted. |
|
▲ 18-Month Warranty
EVER POWER’s 18-month warranty exceeds the 12-month standard of most European OEM suppliers. |
Structure and Material Technology
All gear stages use 17CrNiMo6 case-hardening steel manufactured to vacuum-degassing standards for superior core impact toughness. The output shaft is 42CrMo4 through-hardened, providing high bending stiffness for cantilevered coupling loads. A thermal monitoring boss (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 system for outdoor and marine auxiliary applications.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Cement | Vertical roller mill drive | High-efficiency drive for energy-intensive vertical grinding mill. |
| Mining | Large ore SAG mill auxiliary | High torque sustained over long continuous operating cycles. |
| Marine | Ship thruster auxiliary drive | Reliable low-speed output for large vessel thruster systems. |
| Ports | Gantry crane travel drive | High torque for loaded container gantry crane travel on rail. |
Selection Guide
- Required Output Torque (Nm) — Confirm peak and continuous torque with safety factor of 1.3-2.0.
- Gear Ratio — Motor speed (rpm) / required output speed (rpm). Range: 50:1 – 500:1.
- Stage Count — 4-stage provides ratio range 50:1 – 500:1. Higher stages = higher ratio and lower efficiency.
- Motor Interface — Flange type (SAE / IEC metric), shaft diameter and keyway.
- IP Rating — IP66 is standard. IP67/IP68 upgrade available for washdown or outdoor service.
- Mounting Orientation — Horizontal, vertical or inverted; all supported with standard oil-bath lubrication.
- Operating Temperature — Standard -25 to +80 degC; Arctic and high-temp variants available.

Frequently Asked Questions
Q: Is third-party inspection available?
A: Yes. DNV GL, Bureau Veritas, SGS, and TUV inspection can be arranged. Please specify the inspection requirement at order, as it adds approximately 1-2 weeks to the standard lead time.
Q: What is the maximum shock load capacity?
A: Standard units are rated for momentary overload torques of 2.5x the rated output torque. A reinforced variant rated for 3.0x momentary overload is available for high-shock applications such as conveyor head drives with belt sag loading.
