EP-SL4001 Single-Stage Inline Planetary Gearbox
Brevini Riduttori SL4001 Compatible Replacement | EVER POWER
The EP-SL4001 is EVER POWER’s independently engineered single-stage inline planetary gearbox, designed as a direct replacement for the Brevini riduttori SL4001. Delivering approximately 4,000 Nm output torque with IP65 sealing and a mounting interface dimensionally compatible with the original Brevini unit, this gearbox serves industrial machinery, conveyor systems, mixer drives, material handling equipment and processing plant drives where reliable torque multiplication and long service life are essential. EVER POWER’s SL series inline planetary gearbox combines competitive pricing with 18-month warranty coverage and faster delivery than typical European OEM lead times.

مبدأ العمل
The EP-SL401 operates on the epicyclic planetary gear principle. A single planetary stage is coaxially arranged within the sealed housing. The input sun gear meshes simultaneously with multiple planet gears orbiting within a fixed ring gear, distributing the load across all contact points simultaneously. This load-sharing principle is why planetary units achieve significantly greater torque density than parallel-shaft designs of equivalent housing diameter. A precision-ground output shaft or hollow bore transmits the multiplied torque to the driven machine with minimal backlash.
المزايا الأساسية
|
● 4,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
▲ Single-stage Efficiency
Maximum efficiency single mesh path for the required application. |
|
◆ Brevini SL401 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. |
تكنولوجيا الهياكل والمواد
The housing is precision-cast from حديد مطاوع GGG50 and machined to H7 bore tolerances. Planet gears are manufactured from 20CrMnTi case-hardening steel, carburised to 0.7-1.0 mm case depth and profile-ground to DIN 5 accuracy. The output shaft is supported by back-to-back tapered roller bearings pre-loaded at the factory for zero axial play under combined radial and axial loads. All external shaft seals are FKM fluoroelastomer rated for synthetic gear oil service at up to 120 degC. External coating is two-coat epoxy primer + polyurethane topcoat, 480-hour salt spray rated.
سيناريوهات التطبيق النموذجية
| صناعة | طلب | Key Benefit |
|---|---|---|
| Paper | Large reel stand unwind drive | High torque for controlled unwind of heavy paper reel. |
| Recycling | Industrial shredder infeed | High starting torque handles dense material feed into shredder. |
