The gear meshing surface is prone to wear during use, and the gears are prone to partial tooth breakage when subjected to impact loads. The laser cladding process can be used for local and selective repair. It has the advantages of a flexible process, strong bonding strength between the repair layer and the tooth surface, a small heat-affected zone, a dense structure, and a low dilution rate. It is very suitable for the tooth surface of gears. Repair application.

Due to the harsh working environment and long-term overloading, the tooth surface of the reduction gear is severely worn and pitted, and the gap between meshing is increased, resulting in impact vibration and noise exceeding the normal allowable range during operation. The common solution is to directly replace the gear shaft. However, since this type of gear shaft is not a single component and has a transmission turbine integrated at the end of the shaft, it can only be replaced as a whole. The cost is too high, but the laser cladding technology independently developed by Huirui can very well repair the reduction gear.

Repair name: Reduction gear repair
Material: 20CRMNTI
Requirement: Use inner hole laser cladding to produce a material equal to 3mm and the reduction gear.
