Management method
Gas springs were adopted because they have the advantage of being lighter and easier to replace than coil springs, but as they are devices that use high-pressure gas, natural leaks may occur, so periodic inspection and replacement by the user is required. (Reference: Main unit manual 4-2)
Inspection is performed every 6 months, and gas charging or replacement is required if the pressure drops. (Reference for details: Chapter 9 of the main unit manual).
If leakage is left unattended, it may cause damage to the gas spring and drive system (motor/reducer). (Caution: If the pressure of the gas spring is lowered, depending on the load, there is a risk of the axis falling when the servo is turned off in the maximum radius position.)
What to do under pressure
- Above 100 bar: No or little leakage. Maintain or charge to 140 bar.
- Below 100 bar:
- When gas charging is possible: If the pressure is maintained after charging, use it. If there is a rapid leak after charging, request gas spring replacement or repair. The lifespan of the gas spring is 3 to 4 years (20,000 hours), and periodic repair/replacement is recommended.
- If there is no charger: Contact Hyundai Robotics A/S. (Gas charging and exchange)
Apply monitoring software
- Provides a function to monitor the pressure of the gas spring for efficient management. (Applies to MV40.11 or higher, recommended MV40.17 or higher)
