Abstract

The invention discloses a damaged gear laser real-time dynamic cladding repair and stress control system, including an optical infrared coupling dynamic monitoring and measurement system, a laser cladding system, a laser impact system, and a clamping platform respectively connected to a central control system; The thermal effect of the laser realizes the cladding of the cladding material; the shock wave generated when the laser irradiates the material acts on the surface of the laser cladding layer material, realizes the strengthening of the laser cladding layer, and eliminates the cladding during the laser cladding process. Defects such as pores and sparse structures in the cladding. This repair method is suitable for failure forms such as gear fatigue cracks, pitting, broken teeth, and tooth surface wear. Through laser cladding repair, the shape of the gear tooth profile can be quickly restored without wasting cladding materials; through laser shock stress regulation, eliminating The defects generated during the laser cladding process ensure the mechanical properties of the repaired gears, and subsequent complex machining is not required, which improves the repair efficiency and reduces the cost of gear repairs.

Description

technical field [0001] The invention relates to a laser system and method for real-time repairing of damaged gears, in particular to a laser real-time dynamic cladding repair and stress control system and method for damaged gears. Background technique [0002] Gears are important transmission components in the field of mechanical applications and are widely used in the entire national production. The failure forms of the wheel mainly include tooth surface pitting, tooth wear, broken teeth, etc. For some large-sized alloy hard gears, due to the long production and processing cycle, the large amount of tool loss in the processing process, and the high price of processing materials, the cost of direct replacement of damaged gears by enterprises has increased. Therefore, there have been some researches on the process of repairing damaged gears. Common repair processes for gears include surfacing, cladding, arc deposition, and laser cladding. [0003] The invention patent with...
