The robot vacuum cleaner drive wheel lifespan test bench is designed for simulating real-world usage conditions to test the aging

 and lifespan of robot vacuum cleaner drive wheels. It is controlled by a PLC and configured through a 7-inch touch screen. A DC power 

supply continuously powers the robot vacuum cleaner, and a magnetic powder brake is used to test the durability and lifespan of the drive wheel. 

The test simulates real-world usage conditions based on the number of tests and duration. Relevant test data can be exported via USB. It is versatile, easy to operate, convenient to control, and has a low failure rate.

1. Durability test of drive wheel assembly

- Continuous rotation durability: Set total mileage (such as 500km~1000km) or time

- Intermittent start-stop durability: periodic forward rotation, reverse rotation, start-stop, simulating actual use

- Inspection items: tire wear, wheel hub cracking, degumming, deformation, and skidding

2. Obstacle surmounting and impact durability test

- Climbing over obstacles of a fixed height (such as thresholds/steps of 10mm to 20mm)

- Cyclic drop impact, repeated rolling impact

- Inspection: fracture of wheel arm, deformation of bracket, looseness of bearing, and loosening of fasteners

3. Load climbing performance and durability

- Set a gradient (8°~15°) for continuous climbing operation

- Detection: motor current, torque decay, tire slip, temperature rise, transmission failure

4. Drive motor performance test

- Operating current, locked-rotor current, operating temperature rise

- Motor insulation, commutator/carbon brush wear, encoder signal stability

- After prolonged operation, there may be a decrease in rotational speed, abnormal noise, and seizure

5. Durability of transmission system

- Fatigue test of gearbox/reducer

- Gear wear, broken teeth, lubrication failure, abnormal noise, increased clearance

- Belt/drive belt stretching, slipping, or breaking

6. Tire wear resistance and friction performance

- Tire wear, thickness reduction, and surface peeling

- Changes in grip and slip ratio on dry and wet surfaces

- Material aging, hardening, and cracking

7. Vibration and noise testing

- Operational vibration value, structural resonance

- Variation of noise level over the life cycle

8. Environmental adaptability enhancement test (optional)

- Durability under high and low temperature cycling

- Operating in a dusty environment (dust-proof, anti-clogging)

- Insulation and corrosion under hot and humid conditions
