Description

The 3HAC025007-001 is a high-precision reduction gearbox manufactured by ABB, specifically engineered for the third axis (J3) of the IRB 6620 and IRB 460 industrial robot series. This component serves as the critical transmission interface between the servo motor and the robot arm, converting high-speed motor rotation into high-torque mechanical movement.

Designed with a robust cast iron housing and a transmission ratio of 160:1. the 3HAC025007-001 ensures exceptional rigidity and positioning accuracy. It is the definitive solution for maintaining the structural integrity and dynamic performance of ABB’s heavy-payload robots in demanding industrial environments

.

Application Scenarios

Consider a high-volume automotive stamping plant where an IRB 6620 robot is tasked with transferring heavy steel chassis parts between presses. The robot must move rapidly, stop with absolute precision, and hold the load steady against gravity. In this scenario, the 3HAC025007-001 is the unsung hero of the operation.

Located at the robot’s J3 axis (the main arm lift), this gearbox absorbs the immense torsional forces generated by the payload. Without the precise gearing of the 3HAC025007-001. the robot would suffer from “backlash” (play in the gears), leading to inaccurate part placement or, worse, a catastrophic drop of the heavy steel component. By utilizing this reduction gear, the system ensures that the heavy payload is manipulated with the same finesse as a lightweight object, safeguarding both the production line and the equipment.
