EP-EC2155 2-Stage Compact Planetary Gearbox
Brevini Riduttori EC2155 Compatible Replacement | EVER POWER
De EC2-series delivers the efficiency and ratio range of a 2-stage planetary design in a radially compact housing specifically engineered for tight-envelope OEM installations. The reduced housing diameter versus the ED2-series makes EC2 units the first choice for motor-integrated drives, AGV wheel hubs, linear actuator heads, robot joint drives and space-constrained automation equipment.
De EP-EC2155 replaces the Brevini riduttori EC2155 ?? a 2-stage compact planetary gearbox delivering approximately 16,150 Nm output torque, ratio range 8:1 – 40:1, and IP rating IP65.

Arbetsprincip

The compact design uses a thin-ring construction ?? the ring gear bore and housing outer diameter are minimised through careful gear module selection, reducing the housing diameter by up to 15% versus the standard ED2 series at the same torque rating. Both stages use needle-roller planet journals for maximum radial stiffness in the reduced-diameter housing, maintaining planet-to-ring gear mesh accuracy under cantilevered load conditions.
Kärnfördelar
|
◆ Compact Radial Envelope
Up to 15% smaller OD vs ED2 ?? fits tight machine bores and hubs. |
◆ Needle Roller Planet Journals
Maximum planet radial stiffness in thin-ring housing. |
|
◆ Motor-Integration Compatible
Short axial length suits motor-gearbox integrated units. |
◆ 5,000 rpm High Input Speed
Servo and high-speed motor compatibility. |
|
◆ Direct EC2-Series Replacement
Same mounting dimensions as Brevini original. |
Struktur och materialteknik

Housing is machined from 7075 aluminium alloy or GGG50 iron depending on size. Planet gears use 20CrMnTi carburised steel, ground to DIN 6. Thin-ring construction requires press-fit ring gear installation with Loctite 638 retaining compound for permanent bore fixation. Output shaft seals are double-lip NBR for dust and oil retention in compact housings.
