The ball mill is a large ring gear, a large generic mass, generally a combination of two half a ring, 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 matched.
The installation method of the large tooth is commonly used to secure the ring gear 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 secure end caps and cameras to the same side of the cylindrical flanges, respectively. It has increased 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 breaks 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 for material, and the hardness of HB220 ~ 250 was treated with 35 SiMn, 45MNB, 40Cr.
The lubrication of the ring gear is released by the energy-saving ball mill. The article is for reference only)
A. Oil pump fuel-proof lubrication (dilute oil concentrated lubrication) Dilute oil concentrated lubrication is made of oil pump, valve, tubing Composed with the injector, the bottom of the gear cover and the fuel tank.
B, the large tooth ring with oil lubrication, and practice proves that this lubrication method is the worst.
C, the tanker is lubricated, and the tanker belt has no survival overcomes the disadvantage of the large ring gear with oil, so it has been applied.
