EP-EC2250 2-Stage Compact Planetary Gearbox
Brevini Riduttori EC2250 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-EC2250 replaces the Brevini riduttori EC2250 ?? a 2-stage compact planetary gearbox delivering approximately 30,400 Nm output torque, ratio range 8:1 – 40:1, and IP rating IP65.

Жұмыс принципі
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.
Негізгі артықшылықтары

Құрылым және материал технологиясы
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.

Жиі қойылатын сұрақтар
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.
