The planetary reducer is installed in the head and tail of the conveyor to adjust the working speed of the sprocket shaft set and the carrying capacity of the scraper chain, so as to suit the working needs of different design power and rotating speed of the scraper conveyor. According to the different structural characteristics of the reducer, the use of different, its general classification is as follows: 1. According to the series of transmission, it is divided into single-stage reducer and multi-stage reducer 2. According to the type of transmission, it is divided into fixed-axis reducer and planetary reducer 3. According to the layout requirements of scraper conveyor, it can be divided into parallel layout type and vertical type Scraper reducer is mainly used for planetary reducer. Compared with fixed-shaft gear transmission, planetary gear transmission has more compact structure, more stable transmission, larger transmission ratio of the same series, and better performance in bearing capacity. But because this kind of decelerator usually has three or four planetary wheels in the planetary frame design, its structure is more complex, the parts processing precision request is higher. The main parts of scraper planetary reducer include one shaft assembly, two shaft assembly, three shaft assembly, output tie rod assembly, sun wheel, inner gear ring, box assembly, cooling device and lubrication system. Above is the scraper planetary reducer structure characteristics. Want to know more coal machine accessories, please continue to pay attention to us. Henan Shuangzhi Machinery Equipment Co., LTD.
