The material has a great influence on the sprocket and shaft set of the scraper. The high quality material and good processing technology can make the sprocket and shaft set of the scraper achieve good performance. Henan Shuangzhi carries out strict quality inspection on the sprocket shaft group of the plate scraper. The sprocket shaft group shall meet the following performance requirements before delivery:

1. Good hardness

The quenching and tempering process is very important for the sprocket shaft set. The hardness of the tempered sprocket shaft set should reach HB260-300. After quenching the sprocket body of the sprocket shaft set, the hardness shall reach HRC50-55.

2. Good toughness

The service life of sprocket shaft set is also greatly affected by the toughness of materials. If the sprocket shaft assembly has good toughness, it can reduce the brittle fracture of the sprocket and reduce the material removal caused by the fracture mechanism. Under the influence of the working condition and working environment of the sprocket shaft set, the toughness of the sprocket wheel can be adjusted to reduce the generation of cracks and wear.

3. Good hardenability

The good hardenability of sprocket is helpful to obtain martensite of sprocket and improve the uniformity of quenching.

4. High wear resistance

During the operation of the scraper, the sprocket is in direct contact with the chain of the scraper, which is prone to wear. Once the wear is serious, it will affect its operation. Improving the wear resistance of sprocket shaft set is helpful to improve the service cycle of sprocket.
