High-ratio conversion
The 236.36 reduction turns relatively fast motor rotation into the slower output required at axis 6. That relationship allows the wrist to develop torque without treating motor speed as joint speed.

Model Information
ABB RV-500N-236.36 3HAC048293-001 is the axis-6 reduction gear installed at the end of the upper arm on the ABB IRB 8700 robot. Its 236.36 reduction converts motor-and-pinion input into the slower, higher-torque rotation required by the robot's terminal wrist axis.
Inside the wrist drive, ABB RV-500N-236.36 3HAC048293-001 receives rotation through the axis-6 pinion and carries the reduced output to the wrist interface. Gear mounting, lubrication, sealing and the connected motor-feedback path work together; changing only one of those relationships can affect backlash, position accuracy or load transfer.
Replacement of ABB RV-500N-236.36 3HAC048293-001 requires support of the wrist and attached load, isolation of drive energy and protection of open mechanical interfaces. The gear is seated without using fasteners to pull misaligned parts together, then the axis is calibrated and tested at controlled speed.

Performance Characteristics
ABB RV-500N-236.36 3HAC048293-001 shapes the speed, torque and positional behavior of the IRB 8700 terminal wrist axis through one high-ratio mechanical path.
Rigid torque path
The pinion, reduction stages and output interface carry reversing loads through the wrist structure. Mounting faces and fastener sequence therefore influence how evenly those loads enter the gear.
Position relationship
Resolver data is measured at the motor side while the robot model interprets the geared joint position. Backlash or disturbed mounting can therefore appear as a mechanical response issue even when feedback remains electrically stable.
04
Installation Highlights
Install ABB RV-500N-236.36 3HAC048293-001 with the wrist supported and every sealing, lubrication and calibration step tied to the same axis-6 service record.
Unload the assembly
Remove payload influence, position and support the wrist, isolate energy and secure the axis before separating the motor, covers or upper-arm interface.
Seat and seal the gear
Protect open surfaces, transfer required seals and lubrication, align the gear to its locating features and tighten in sequence without using bolts to overcome misalignment.
Verify the restored path
Reconnect the motor and feedback chain, restore covers, calibrate axis 6 and run limited motion while checking sound, current, direction and repeatable return to reference.
