In the course of use, automobile gears will inevitably wear out, and cracks will occur over time. At this time, they cannot be manually repaired, but must be repaired with reference to professional gear technology. The professional gear maintenance process includes a total of ten parts, including: digging, grinding, cleaning the surface, phosphating the surface, burning alloy powder, cladding welding repair, grinding welding layer, correction, polishing, acceptance. The operating process and gear production process are comparable in accuracy requirements.
Gearbox crack repair has always been a problem in motor repair. The reasons for this include the following: First, design and production reasons; second, random momentum impact from the outside world; and third, non-uniform engine operation and inconsistent wind pressure lead to cracks.
Traditional repair methods include:
One is to ensure normal use of 500 hours, you can use ordinary welding electrode repair technology;
The second is to ensure the normal use of 700 hours, you can use the method of combining ribs with common electrode repair welding;
The third is to ensure the use of 4,000 hours, you can use ordinary welding rods and sleepers combined method;
Fourth, the effect is not very good high-strength steel repair welding, but easily lead to uneven intensity, resulting in new cracks around it, the result is edge welding edge cracking, high precision requirements, expensive car repair is not recommended. At present, a new method uses the method of adding a spring rubber seat to reduce the effect of vibration.
