See the structure, material and lubrication of the ball mill large ring gear

　　The ball mill is a large ring gear, a large body weight, generally a combination of two half a ring gear, so that it is easy to disassemble. The number of teeth of the ring gear is an even number, and the opening is to be on the tooth, and the two half returns should be accurately consistent.

　　The installation of the large tooth is generally used, which is fixed to the barrel or end cover flange with bolts. Some use a row of bolts to fix the grinding end cap, the cylindrical flange and the large gear flange. The three shared a row of bolts, and it is not convenient to repair the big gear. This structure is suitable for small and medium-sized ball mills. Some use two rows of bolts to fix end caps and cameras to the same side of the cylindrical flange. It increases the size of the ring gear, which is suitable for large ball mills. The destruction of the edge transmission size gear is mainly due to the wear and bending break of the tooth surface.

　　Therefore, the gel material is required to have sufficient strength, high wear resistance and good workability. At present, the material of the large ring gear generally uses ZG270 to 500, ZG310 ~ 570, but it must be protected by normal fire before processing, and the hardness is reduced to HB170 ~ 200. The pinion was used in 35siMn, 45 mnb, 40Cr, and the hardness of HB 220 ~ 250 was retreated.

　　The lubrication of the ring gear (the article is collected by the energy-saving ball mill, the article is for reference only) A. The oil pump fuel-proof lubrication (dilute oil concentrated lubrication) The concentrated lubrication of the oil pump, valve, tubing and injector, and raw jewelry The bottom is also used as a tank. B. The big gear is lubricated, and the practice proves that this lubrication method is the worst. C. The tanker is lubricated, and the tanker belt has no moisture overcomes the disadvantage of the large ring gear with oil, so it has been applied.
