EP-EC2320 2-Stage Compact Planetary Gearbox
Brevini Riduttori EC2320 Compatible Replacement | EVER POWER
The 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.
The EP-EC2320 replaces the Brevini riduttori EC2320 ?? a 2-stage compact planetary gearbox delivering approximately 43,700 Nm output torque, ratio range 8:1 – 40:1, and IP rating IP65.

動作原理
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.
主な利点
|
◆ 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. |
構造と材料技術
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.

よくある質問
Q: How much smaller is the EC2 housing compared to ED2?
A: The EC2 outer diameter is typically 12-15% smaller than the equivalent ED2 unit at the same torque rating. Axial length is also reduced by approximately 10%.
Q: Is the EC2 available with hollow through-shaft output?
A: A hollow output bore option is available for most size classes. Specify bore diameter and keyway at order.
