Reduce motor speed
The gear converts high-speed motor rotation through the 242.73 ratio, producing the lower output speed required by the robot joint.

ABB RV-550E 3HAC024316-001 Axis-2 Reduction Gear
A configuration-controlled RV-550E reduction gear used in the axis-2 drive train of specified ABB IRB manipulators.
01
Product Summary
ABB RV-550E 3HAC024316-001 is an axis-2 reduction gear used in specified ABB IRB 6620 and IRB 6640 manipulator configurations. Mounted between the axis motor and arm structure, the RV-550E transmits motor rotation through its 242.73 reduction ratio so the second robot axis moves with the commanded torque and position relationship.
The mechanical interfaces of ABB RV-550E 3HAC024316-001 connect the drive motor on the input side and the axis structure on the output side. Correct seating, fastener sequence and lubrication condition preserve the gear-to-axis relationship; the motor and resolver feedback remain part of the surrounding drive chain rather than the gear itself.
When ABB RV-550E 3HAC024316-001 is exchanged, the manipulator is secured against gravity movement before the motor or gear fasteners are released. After installation, the axis is checked for free mechanical movement, leakage and abnormal sound, then calibration and controlled-speed motion confirm that the drive train has returned to the recorded axis position.

Product Functions
ABB RV-550E 3HAC024316-001 performs the mechanical conversion between the axis-2 motor and the moving arm structure.
Multiply joint torque
The same reduction path increases available joint torque at the output flange while the controller continues to regulate motion through the drive system.
Hold the axis relationship
The input and output interfaces keep motor rotation, resolver feedback and mechanical joint movement tied to the same axis-2 drive train.
04
Installation Highlights
The manipulator load is secured first; gear alignment and controlled recommissioning follow after the mechanical interfaces are exposed.
Secure the arm
Place the robot in the specified service position, isolate power and support the axis so gravity cannot rotate the arm when the drive train is opened.
Transfer the gear
Mark motor and flange positions, preserve shims and fastener locations, seat the RV-550E without impact and apply the documented tightening sequence.
Verify axis motion
Restore lubrication and covers, move the axis at controlled speed, inspect for leakage or abnormal noise and complete the required calibration check.

Customer Questions
Which robot axis uses ABB RV-550E 3HAC024316-001?
ABB RV-550E 3HAC024316-001 is documented as the axis-2 reduction gear in specified IRB 6620 and IRB 6640 configurations.
What ratio is associated with ABB RV-550E 3HAC024316-001?
ABB RV-550E 3HAC024316-001 uses an RV-550E reduction ratio of 242.73:1.
Why must the arm be supported before removing ABB RV-550E 3HAC024316-001?
Removing ABB RV-550E 3HAC024316-001 opens the axis-2 drive train, so the arm must be secured against gravity-driven movement.
Does ABB RV-550E 3HAC024316-001 include the motor control electronics?
No. ABB RV-550E 3HAC024316-001 is the mechanical reduction gear; the motor, resolver and controller drive hardware are separate parts of the axis system.
What should be checked after installing ABB RV-550E 3HAC024316-001?
Check ABB RV-550E 3HAC024316-001 for correct seating, lubrication, leakage, free movement and abnormal sound before completing calibration and controlled-speed motion.
Why is the complete record ABB RV-550E 3HAC024316-001 needed?
The RV-550E type identifies the gear family, while 3HAC024316-001 identifies the exact ABB ordering record used for the documented robot configuration.
