Currently, industrial technology is becoming increasingly mature, enabling various mechanical devices to achieve integrated operations. Couplings, as crucial components in the transmission of power for wind power equipment, require high quality to perform effectively. Therefore, when many owners choose couplings, quality often ranks first.
The wind turbine coupling is an important component of the wind turbine, serving as a connecting piece between the gearbox and the generator. It plays a crucial role in transmitting torque and rotational speed, while also compensating for misalignment between the gearbox output shaft and the generator input shaft, and providing overload protection for the transmission chain. The main accidents that occur during the use of wind turbine couplings are coupling breakage and slippage.
The treatment method for coupling slippage requires targeted measures based on the specific cause of the fault, including tightening connecting parts, replacing worn components, and adjusting installation accuracy.
Core steps for handling coupling slippage
1. Check and tighten connecting parts
Immediately inspect fasteners such as bolts and nuts, and retighten them to the standard torque if any looseness is found.
If the bolt is broken or the thread is damaged, replace it with a high-strength bolt and avoid overload operation.
2. Replace the failed component
Elastic components (such as rubber pads and pin rollers) should be replaced promptly when they become worn or aged. It is recommended to choose materials that are resistant to high temperatures and aging.
If the tooth surface of the gear coupling is found to be worn or glued, it is necessary to repair the tooth profile or replace the coupling, and strengthen lubrication.
3. Adjust the installation accuracy
Use a dial gauge for two-axis alignment inspection. If the vertical deviation exceeds 0.05mm/m, adjustments should be made by adding or removing shims.
When the axial deviation is too large, the three-meter measurement method is used to eliminate the influence of axial play, ensuring that the coaxiality is ≤0.1mm.
Treatment plan for special working conditions
Overload protection: Apply finite element analysis technology in the coupling of wind turbines to monitor and predict failure risks through the slip angle of friction plates.
High temperature environment: Check the temperature of the coupling every 2 hours, and activate the forced cooling system when it exceeds 80℃.
