IRB 6700 Wrist Pinion Assembly for the IRB 6700 system.

Product Summary

ABB RV-80 3HAC043074-002 is the pinion execution associated with the RV-80 wrist drivetrain in the IRB 6700 robot. It transmits motor rotation into the mating reduction gear and establishes the input relationship for the wrist axis.

Tooth engagement, shaft seating and the motor-side interface determine how ABB RV-80 3HAC043074-002 transfers motion. The article must be identified separately from the complete reduction gear because a pinion and a gearbox do not share the same removal, inspection or replacement scope.

After ABB RV-80 3HAC043074-002 is installed, the mating gear path is turned slowly before full motion. Contact pattern, noise, end play and feedback direction are checked, then the wrist axis is calibrated with the complete drivetrain assembled.

Product Functions

ABB RV-80 3HAC043074-002 forms the first mechanical stage between the wrist motor and reduction gear; it must transmit rotation without adding misalignment or abnormal tooth load.

Accept motor rotation

The motor-side coupling positions the pinion shaft so commanded rotation reaches the gear mesh.

Engage the reduction stage

Correct tooth contact distributes load across the mating gear rather than concentrating force at one edge.

Preserve wrist feedback

A stable input path lets encoder feedback correspond to actual wrist movement during calibration and operation.

Diagnostics and Protection

Troubleshooting ABB RV-80 3HAC043074-002 separates pinion-interface faults from problems inside the complete wrist gearbox.

Inspect tooth condition

Look for scoring, chipped edges or uneven contact that can create periodic noise and vibration.

Check seating and end play

Confirm the shaft and coupling are fully seated; movement at the interface changes backlash and feedback response.

Protect the restored mesh

Use clean lubricant and sealed covers, then monitor low-speed sound and current before loading the wrist.

Customer Questions

Q01Why should ABB RV-80 3HAC043074-002 not be ordered as the complete wrist gearbox?+

ABB RV-80 3HAC043074-002 is the pinion execution in this record; confirm the failed boundary because a pinion and complete reduction gear have different removal and replacement scopes.

Q02What tooth condition should be checked on ABB RV-80 3HAC043074-002?+

Inspect ABB RV-80 3HAC043074-002 for chipped edges, scoring, pitting and uneven contact; one-sided wear can point to shaft or housing misalignment rather than only tooth damage.

Q03How can poor seating of ABB RV-80 3HAC043074-002 be detected?+

Measure the documented seating and end play of ABB RV-80 3HAC043074-002, then turn the assembled mesh slowly; periodic resistance or changing backlash requires reinspection before power.

Q04What contamination risk matters during ABB RV-80 3HAC043074-002 installation?+

Dust, damaged seal material or mixed lubricant at ABB RV-80 3HAC043074-002 can enter the gear mesh, so the work area, tools, parts and opened housing must remain controlled.

Q05Why is low-speed observation important after ABB RV-80 3HAC043074-002 replacement?+

Low-speed reversal lets ABB RV-80 3HAC043074-002 tooth contact, noise, feedback direction and motor current be checked before high torque can amplify an assembly error.

Q06What should identify an ABB RV-80 3HAC043074-002 enquiry?+

State ABB RV-80 3HAC043074-002, robot serial, wrist axis, associated gearbox record, observed wear or noise, and whether the pinion or complete drivetrain has been dismantled.
