Abstract

The invention discloses a laser real-time dynamic cladding repair and stress control system of damaged gears. The system comprises an optical-infrared coupled dynamic monitoring and measuring system, a laser cladding system, a laser impact system and a clamping table respectively connected with a center control system; the cladding of cladding materials is realized through the heat effect of cladding laser; and impact waves generated by impacting on laser radiated materials are acted on the material surface of a laser cladding layer to realize reinforcement of the laser cladding layer and to eliminate such defects as air holes and loose structures generated in the cladding layer in the laser cladding process. The repair method is suitable for such failure forms as gear fatigue cracks, pitting, gear breakage and gear surface wear, and quickly realizes the shape recovery of gears through laser cladding repair without wasting classing materials; and through laser impact stress control, the defects generated in the laser cladding process are eliminated, the mechanical performances of the repaired gears are guaranteed, subsequent complicated machining is not needed, the repair efficiency is improved, and the gear repair cost is reduced.

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 wi...
