3. On-Site Fault Maintenance Case
Case 1: T-Series FALK Coupling Vibration and Noise Fault - Application Scenario: A conveyor system in a coal mine. Fault Phenomenon: The coupling generates obvious vibration and abnormal noise during operation, and the conveyor belt runs unsteadily. Maintenance Process: 1. Use a laser alignment instrument to detect the coupling, finding that the angular misalignment reaches 5°, exceeding the rated limit of 3°; 2. Check the elastic element, which is severely worn and cracked (caused by long-term misalignment); 3. Adjust the motor and reducer to correct the alignment, ensuring the angular misalignment is within 2°, and replace the worn elastic element with a new one of the same specification. Fault Resolution: The coupling operates stably without vibration and noise, and the conveyor system runs normally.

Case 2: ET-Series FALK Coupling Transmission Failure - Application Scenario: A food processing line's packaging machine. Fault Phenomenon: The coupling slips, leading to inconsistent packaging speed. Maintenance Process: 1. Disassemble the coupling, finding that the set screws are loose and the POM hub has slight wear; 2. Check the installation torque of the set screws, which is lower than the rated value; 3. Clean the hub and shaft surface, apply thread locking adhesive, and tighten the set screws to the rated torque with a torque screwdriver; 4. Polish the worn part of the hub slightly to ensure smooth contact. Fault Resolution: The coupling no longer slips, and the packaging machine's speed returns to normal.
