Product Name: Remanufactured High-Life Sprocket Shaft Assembly
Technical Features: Remanufacturing of sprocket shaft assemblies is a core technology for the remanufacturing and maintenance of scraper conveying equipment, covering the repair of components such as sprocket discs, shafts, bearing housings, spline shafts, and floating seal cavities. A robotic welding system and Cold Metal Transfer (CMT) welding technology are adopted, with programming for the above components performed using 3D modeling software (Creo) and offline programming software. This enables precise welding of arc surfaces for sprocket disc remanufacturing, equal-layer additive surfacing, and direct forming of chain pockets, delivering corrosion resistance and impact resistance. The chain pocket hardness is ≥ HRC53, with a small hardness gradient and uniform microstructure, and the service life is 1.5 times that of ordinary quenched sprockets. The overall cost is approximately 45% of new products, the overall service life reaches more than 95% of the performance of new products, the surfacing qualification rate reaches 100%, efficiency is increased by 155.8%, 100% recycling of scrap metal is realized, and more than 90% of wear scenarios can be covered, resulting in wider applicability.
