Turning Gear Tool

Precision, High-Efficiency, and Full-Featured Wind Turbine Turning Solutions
The turning gear tool is a specialized auxiliary system for wind turbine installation and O&M, primarily utilized for doubly-fed or semi-direct drive models. Driven by a motor through a reduction mechanism, it rotates the turbine hub to position blades at the specific angles required for technical operations. The product features mechanical locking and follow-up functionality, equipped with comprehensive safety protection and superior anti-corrosion performance.

Turning Gear Tool

  • Multi-motor synchronized operation with intelligent logic control ensures highly uniform torque distribution.

  • The PLC-based closed-loop servo control system provides high-precision positioning for the turning gear angle.

  • Equipped with dual mechanical locks and monitoring devices to prevent misoperation, ensuring maximum reliability.

  • Features a “Blade Following” function; no disassembly is required if operations stop during special circumstances.

  • Drive redundancy. In the event of a single drive failure, the remaining drive units can still complete the turning operation.

  • Multiple selectable operation modes with safety interlocks for secure handling.

  • Integrated protection against lightning, short circuits, overcurrent, and overvoltage.

PRODUCT DETAILS

Servo Motor

Utilizing closed-loop control technology, the motor enables precise adjustment of rotational speed and torque, ensuring a smooth and controllable turning process.

Gear Reducer

Featuring a planetary gear structure with high load-bearing capacity, it converts the high-speed motor input into the low-speed, high-torque output required for the turning process.

Housing

The optimized mechanical structure provides robust support for the entire unit, offering reliable protection and structural integrity for the internal transmission system.

Adapter Disc Assembly

The adapter disc is designed with a universal interface, featuring high precision in end-face runout and coaxiality to effectively eliminate additional loads and vibrations caused by installation deviations.

Reaction Arm

The reaction arm effectively transmits reaction forces to the mainframe while automatically compensating for installation angle deviations, preventing additional stress and potential equipment damage.

Electrical Control Cabinet

The control cabinet adopts a modular layout for easy maintenance and future functional expansion. It is equipped with multi-layered protection features to ensure safe and reliable turning operations.
