Harmonic Drive Gearbox Applications

ATO harmonic drive gearboxes can be used to optimize the shape of robots, increase precision, increase strength, improve flexibility, etc., and are widely used in industrial robots, numerical control equipment, medical instruments, military and other fields.

Harmonic drive applications

Tips: Harmonic Drive Gearbox Troubleshooting

During use, the vibration of the harmonic drive gearbox increases, and the noise increases. The main reason is that the components inside the case are too worn or damaged.
The gear tooth surface is worn, the gear shaft hole or keyway is worn; the screw hole at the bearing hole is worn; the shaft surface is worn. The precision of parts can be restored by electroplating.

In order to ensure the service life of the hard tooth surface harmonic reducer, it is necessary to strictly select the type, ensure its safety factor, and operate in strict accordance with the instructions, so as to prolong the service life of the harmonic reducer.

Installation Manual

ATO Harmonic Drive Gearbox Installation Manual

Precautions for installation

When the harmonic drive gearbox is in use, if the output end is horizontally downward, the lubricating grease injected into the inner wall space of the flexspline must exceed the meshing tooth surface.
The installation plane of the rigid wheel and the rigid wheel connection and the installation plane of the flexible wheel and the flexible wheel need to be statically sealed to ensure that the grease will not leak during the use of the harmonic drive gearbox and avoid the reducer from working with little or no oil Time damage.
During the installation process, please do not knock the parts of the harmonic drive gearbox with hard objects, or apply strong pressure to avoid damage to the parts.
If you have any questions during the inspection, please contact ATO.

Tips for using a harmonic drive gearbox

Please use it in the specified environment.
Observe the following conditions when using a harmonic drive gearbox:
Ambient temperature: 0-40 degrees Celsius, no splashes of water, oil, etc.; no corrosive, explosive gas; no dust such as metal powder,
Please use the prescribed method for installation.
Please implement the installation method correctly according to the harmonic drive gearbox manual. If it is not installed correctly, it may cause vibration, loss of accuracy, shortened service life, damage and other failures.
Please use the specified lubricant.
Failure to use the specified lubricant may result in reduced harmonic drive gearbox life.
Please do not disassemble or reassemble the product, otherwise, it will not be able to restore its original performance.
Do not exceed the allowable torque during use, otherwise, it may cause harmonic drive gearbox failure.

Existing reviews of 138 mm Strain Wave Harmonic Drive Gearbox, Ratio 50~120

What are the lead times for drive gearbox?

Thank you for your reply. The custom specs are TBD . But let's say for example, I would want the specs of the 138mm harmonic gearbox with 50 gear ratio but with maximum allowable average load torque to be in the 120~130 nm range in a 70~80mm outer diameter gearbox. Is this something that is possible?
If so, what are generally the lead times for these orders? Thank you!

ATO Responded

Unfortunately, we do not provide such specifications. If the maximum allowable average load torque of the gearbox is required to reach 120~130nm, the outer diameter of the gearbox can only be 138mm or 142mm, not 70-80mm.
