EP-SC4004 4-Stage High-Ratio Planetary Gearbox
Brevini Riduttori SC4004 Compatible Replacement | EVER POWER
When a Brevini SC4004 needs replacement, EVER POWER’s EP-SC4004 delivers a dimensionally compatible solution at a fraction of the OEM cost. This 4-stage high-ratio planetary gearbox produces approximately 4,000 Nm output torque from a sealed IP65-rated housing that installs directly into the original machine mounting without modification. Serving cement, mining, chemical, food processing, paper and marine auxiliary drive applications, the EP-SC4004 from EVER POWER offers a cost-effective alternative backed by ISO 9001:2015 quality management and CE certification.

Принцип роботи
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 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.

Структура та технологія матеріалів
Planet gears use 17CrNiMo6 carburised and profile-ground steel, 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 and bore-ground after hardening for dimensional stability. The planet carrier is a single-piece forged nodular iron construction, eliminating the flex found in welded split-type carriers. Output shaft seals are double-lip FKM for long life in synthetic oil service.
Типові сценарії застосування

Часті запитання
Q: What is the minimum oil change interval?
A: With synthetic ISO VG 220 oil: first change at 500 hours, then every 2,500 hours or 12 months, whichever comes first. Lifetime lubrication is available as an option for sealed-for-life configurations in applications with limited maintenance access.
Q: What ambient temperature range is supported?
A: Standard range is -25 degC to +80 degC. A low-temperature variant with Arctic-grade PAO oil and cold-rated FKM seals is available for service below -25 degC. A high-temperature variant for up to +100 degC ambient is available on request.
