Description

Technical Field

[0001] The utility model relates to the field of disassembly and assembly of dampers, in particular to an auxiliary disassembly and assembly device for the centering spring rod of a yaw damper. Background Technique

[0002] ‌The yaw damper‌ is an automatic flight system, and its core function is to effectively reduce the yaw phenomenon of the aircraft caused by Dutch roll or turbulence by controlling the movement of the rudder. This system remains in an efficient working state throughout the entire flight of the aircraft and usually starts and is ready before the aircraft takes off from the ground. The main components of the yaw damper system include key components such as the rudder. These components work together to ensure the stable flight of the aircraft. In addition, the yaw damper is also called a yaw brake, and it plays an important role during the operation of the wind turbine. The main function of the yaw brake is to absorb minute free deflection oscillations, prevent premature damage of the gear teeth caused by the alternating stress of the yaw gear, and at the same time avoid excessive vibration during the yaw process of the wind turbine generator set, which may cause resonance of the entire machine. This is also one of the important functions of the yaw damper. When disassembling and assembling the damper, a disassembler is required. The disassembly and assembly of the damper is a technical task that requires professional tools and skills to complete. The damper disassembler is a professional tool or equipment for installing and disassembling the damper. The correct use of these tools is crucial for ensuring the effective operation and maintenance of the damper. The prior art requires workers to use a disassembler to remove it by manually tightening and adjusting the position.
