According to the analysis of the working principle, working condition and failure reason of the sprocket shaft group, the quality of the sprocket shaft group is not only related to the processing technology, but also to the material. The material and performance of the sprocket shaft group must meet the processing technology requirements of the sprocket shaft group. When selecting material of sprocket shaft group, its material performance shall meet the following aspects:

Higher hardness

The sprocket shaft group needs to be tempered during the processing, and the hardness after tempering should reach hb250 to hb280. The sprocket body and sprocket shaft need to be quenched, and the hardness after quenching should reach HRC50 to HRC55.

Good toughness

The toughness of the material determines the service life of the sprocket shaft group. The toughness of the material is good, which can effectively prevent the macro fracture of the sprocket and other problems, and also can inhibit the material removal caused by the fracture mechanism. Because the sprocket shaft group is used under high load, it is easy to produce fatigue cracks. The high plasticity and toughness of the material can reduce the generation of cracks.

Excellent hardenability

For the sprocket shaft group, good hardenability improves the ability to obtain martensite, which is conducive to improving the uniformity of quenching structure.

High wear resistance

In the process of working, the sprocket should be meshed with the ring chain, which will cause serious contact wear. Good wear resistance can improve the service life of the sprocket.

Material 42CrMo

The material of each drawing number sprocket shaft group produced by Luoyang vision is 42CrMo. Because 42CrMo is alloy quenched and tempered steel, its mechanical properties are better. After normalizing, tempering and heat treatment, the material has good hardenability, oxidation resistance, corrosion resistance, service life growth and is suitable for working face with bad working environment.

Material and technology are the key factors affecting the quality of sprocket shaft group. When purchasing each drawing No. sprocket shaft group, select the material suitable for the working face according to the material and performance requirements of the drawing No. sprocket shaft group. Luoyang vision mining equipment Co., Ltd. was founded in 1996, is a 24-year experience of coal machinery equipment experts. Many products produced by the company, such as scraper conveyor and scraper transfer machine, have obtained the national safety mark certificate of mining products. The quality and safety of products have been recognized, and the use of customers has also been guaranteed.
