Description

Technical Field

[0001] This invention relates to the field of wind turbine main shaft repair technology, and more specifically, to a laser cladding repair device for wind turbine main shafts. Background Technology

[0002] As a core component of the wind turbine transmission system, the wind turbine main shaft operates under heavy loads and alternating loads for a long time, and is prone to damage such as wear, pitting, and fatigue cracks. Laser cladding has become the mainstream technology for remanufacturing wind turbine main shafts due to its small heat-affected zone, high bonding strength, and controllable repair precision. Existing laser cladding repair devices for wind turbine main shafts mostly employ single-end or double-end clamping and suspended rotation of the main shaft for processing. Wind turbine main shafts are large, long shaft workpieces, prone to radial runout, axial movement, and sagging deformation in the middle section during rotation and cladding. This causes the cladding spot and powder feeding position to deviate from the preset trajectory, resulting in uneven cladding layer thickness and reduced adhesion. Therefore, we propose an improved laser cladding repair device for wind turbine main shafts. Summary of the Invention
