EP-EC4255 4-Stage Compact High-Ratio Planetary Gearbox
Brevini Riduttori EC4255 Compatible Replacement | EVER POWER
El EC4-series delivers 4-stage ratio coverage up to 400:1 in EVER POWER’s most compact RPM-series housing ?? targeting applications where both extreme ratio and minimum housing size are simultaneously required. It serves compact winch drives, small tracked machine travel drives, micro-positioning systems, compact industrial hoist units and tight-envelope high-reduction drives that cannot accommodate full-size 4-stage housing dimensions.
El EP-EC4255 reemplaza al Brevini riduttori EC4255 ?? a 4-stage compact planetary gearbox delivering approximately 102,000 Nm output torque, ratio range 30:1 – 400:1, and IP rating IP65.

Principio de funcionamiento
Four planetary stages are packed coaxially in the compact housing using thin-wall ring gear sections and optimised planet-to-ring gear clearance. The output shaft features a large-diameter bore option allowing a hollow-through shaft configuration ?? enabling the EC4 to be mounted directly on a drive shaft or screw without a separate shaft-to-shaft coupling, which is especially valuable in very compact installations.
Ventajas principales
|
★ Up to 400:1 Compact
4-stage reduction in smallest available housing diameter. |
★ Hollow Through-Shaft Option
Mount directly on drive screw or shaft ?? eliminates coupling. |
|
★ Thin-Wall Ring Construction
Maximum torque density in minimum radial space. |
★ Compact High-Ratio
Replaces tandem gearbox arrangements in space-constrained machines. |
|
★ Direct EC4-Series Replacement
Same mounting pattern as original Brevini unit. |
Estructura y tecnología de materiales
Thin-wall ring gear sections are machined from 42CrMo4 through-hardened steel for maximum stiffness in the reduced wall thickness. Planet gears use acero carburizado 17CrNiMo6, ground to DIN 5. The hollow through-shaft option uses a precision-ground bore to H6 tolerance for interference or clearance fit on the drive shaft. Seals are fluoroelastómero FKM for synthetic oil.

Preguntas frecuentes
Q: What applications benefit most from the hollow through-shaft option?
A: Ball screw drives, spindle through-feeds and cable management channels that must pass through the gearbox centre benefit most. The hollow bore eliminates the need for a separate coupling.
Q: Is the EC4 available with a brake flange?
A: Yes. An input-side spring-applied brake interface boss is available for compact hoisting and winching applications.
