Sprocket assembly is composed of sprocket and connecting roller. It is an important part of scraper conveyor, and it is also the most torque part of conveyor. Therefore, in the process of purchasing sprocket shaft group, many problems should be considered, and we must be very careful. Only in this way can we choose high-quality sprocket shaft group, prolong the service life of sprocket shaft group, and improve work efficiency, otherwise, In the use of the process is prone to accidents, resulting in labor and money, so what should be paid attention to in the process of purchasing sprocket shaft group? What is the price of sprocket shaft group
what problems should be paid attention to in the process of purchasing sprocket shaft group:
with the development of coal machinery and the national rectification and merger of small and medium-sized coal mines, large-scale fully mechanized mining equipment is more and more widely used in coal mines With the development of heavy-ty scraper conveyor, there are more and more types of scraper conveyor, and the models proced by major coal machine manufacturers are also different. As the main vulnerable parts of scraper conveyor, sprocket shaft group is not universal, which makes it difficult to determine when purchasing. So what problems should be paid attention to when purchasing sprocket shaft group? We summarize the following aspects
First, the main engine manufacturer of sprocket shaft group. As there are many manufacturers of scraper conveyor, the sprocket shaft group of each manufacturer can not be used in general, so when purchasing, we must first determine which manufacturer of scraper conveyor is suitable for sprocket shaft group. At present, the most important domestic scraper conveyor manufacturers are China Coal Zhangjiakou coal machinery plant, Ningxia Tiandi Benniu, Shandong mining machinery, Shanxi coal machinery plant and Zheng coal machinery Second, the determination of drawing number of sprocket shaft group. Even for the same scraper conveyor manufacturer, the sprocket shaft group applicable to the same scraper conveyor model may not be the same. Therefore, it is necessary to determine the drawing number of the sprocket shaft group. Each sprocket shaft group has only one set of drawings. As long as you find the drawing number of the sprocket shaft group and have the corresponding drawings, you can ensure that the sprocket shaft group proced will not make mistakes Third, the material selection of sprocket shaft group. Due to the increasing power and transportation volume of scraper conveyor, there are great requirements for the toughness and strength of sprocket shaft group. If the material selection is not appropriate, the sprocket shaft group will be prone to accidents in the use process, affecting the proction progress, and even safety accidents. At present, the commonly used materials are 42CrMo and 45crnimnmu. When selecting, the appropriate materials should be selected according to the transportation volume Fourthly, the manufacturing process of sprocket shaft group. Due to the high requirements for the toughness and strength of the sprocket shaft group, the manufacturing process can not be careless. At present, the manufacturing process of the sprocket shaft group mainly includes forging, casting and welding. Small ordinary mining scraper conveyor can choose casting and welding sprocket shaft group. For large fully mechanized sprocket shaft group, in order to ensure its performance requirements, only forging sprocket shaft group can be selected, and heat treatment, quenching and tempering and other processes can be carried out
when purchasing the sprocket shaft group, we should pay attention to the above aspects. Basically, the sprocket shaft group can basically meet the performance required by the current scraper conveyor, but there is another point to pay attention to, that is, when the scraper conveyor is running, we must pay attention to the wear of the sprocket shaft group at any time to avoid accidents

the above is about the problems that should be paid attention to in the process of purchasing sprocket shaft group and the price introction of sprocket shaft group manufacturer, In the purchase of sprocket shaft group must be very careful, understand all the situation before making a decision, and in the purchase can not be greedy for small cheap Oh, to buy high-quality procts is the king. At the same time, when using the sprocket shaft group, you should often check the wear of the sprocket shaft group and take preventive measures to avoid accidents. I hope the above contents can help you
