Scraper conveyor sprocket assembly is based on a specific set of machine models to determine, but all sorts of figure, scraper conveyor sprocket assembly do have a lot of the same, known as the "borrow" in the design, the production of blowing machine makers are mainly coal zhangjiakou coal mining machinery co., LTD., shanxi coal mine machinery manufacturing co., LTD., xinzhou general machinery manufacturing co., LTD., ningxia and running of the bulls industrial group co., LTD., shandong mining group, etc, because of coal mining environment, factors such as mining bureau requirements, design different kinds of chain wheel component (also called the sprocket shaft group, sprocket assembly).
Zhangjiakou coal machine is one of the earliest manufacturers of scraper machine in China.
Scraper SGZ630\730\764\800\ 900\1000\ 1400 Sprocket shaft set, sprocket assembly, sprocket and transfer machine SZZ630\ 764\800\830\ 900\1000\1200\1400 Sprocket set, sprocket, sprocket, sprocket shaft set use the same figure number, generally is the number/number +LL to express, such as 80/05LL/90\05LL/100\04LL/120\03LL. However, some of the figure Numbers are S-series. For the figure Numbers of major main engine factories, sprocket assembly of various parts of S-series are also adopted accordingly.
The sprocket assembly is an important part of the head of the fully mechanized coal mining scraper. In coal mining, the sprocket is driven by the reducer, and the chain drives the scraper to run in the middle trough, so as to transport coal and other materials. Because the chain is in constant contact with the sprocket body, the sprocket tooth part of the sprocket is easy to wear. After the sprocket tooth is worn, it is easy to cause the failure of the scraper and chain jumping. The sprocket wheel is made of 42CrMo or 40CrNiMoA material, which is suitable for the scraper conveyer of the fully mechanized mining.
The sprocket wheel requires no cracks, interlayer, fold, forging injury, slag clamping, scar and other defects on the surface of the forgings. The sprocket wheel tooth surface has a hardness of HRC50-55, and the depth of the hardened layer is 10mm.
