ABB 3HAC043073-003 / 3HAC060576-002 — IRB 6700 Axis Reduction Gear | ABB Robotics Drive Train
Engineering Background
The ABB IRB 6700 is ABB Robotics’ flagship heavy-payload articulated robot platform, engineered for demanding manufacturing environments including automotive body-in-white, foundry, and heavy material handling. The axis reduction gear is a precision-critical drivetrain component that directly governs repeatability, torque transmission, and service life of the robot arm.
Product Positioning

System Architecture & Signal Flow
The IRB 6700 drivetrain routes motor torque through a servo motor → reduction gear → output flange chain. The reduction gear (3HAC043073-003 / 3HAC060576-002) sits between the axis servo motor and the mechanical arm linkage, providing the gear ratio necessary to convert high-speed, low-torque motor output into the low-speed, high-torque motion required for precise arm positioning. Correct installation torque, lubrication specification, and axis calibration per ABB Service Manual (3HAC028284-001) are mandatory post-replacement steps.
