Product Description
The large gear of the ball mill is one of the important parts of the ball mill. Its main function is to drive the cylinder to rotate according to the set speed ratio. Therefore, there are very strict requirements on the material, hardness and processing hardness of the large and small gears of the ball mill. A qualified ball mill gear product has to go through several complicated processes, and every process must be rigorous, so that such products can meet the standards and customers can ensure normal use.
The delivery of the finished gear of the ball mill goes through the links of design, casting, rough machining, finishing, gear hobbing, etc. The main processing steps are as follows: design - model making → modeling → pouring → sand cleaning → annealing → inspection → rough machining of the joint surface → Drilling and reaming of the joint surface → paired jointing → roughing the outer circle and end face → flaw detection → inspection → performance heat treatment → repairing the joint surface → machining the outer circle and end face → rough hobbing → finishing the joint surface → finishing the outer circle and end face → fine hobbing → complete all processing → oiling → storage
Ball mill large gear installation: The ball mill large gear is large and heavy, and is generally composed of two half-gears, which is easy to disassemble and assemble. The number of gear teeth is even, and the opening should be on the tooth slot, and the two halves of the gear should be exactly matched. The installation method of the large gear is generally used to fix the gear to the cylinder body or the flange of the end cover with bolts. Some use a row of bolts to fix the grinding head end cover, the cylinder flange and the French gear flange. The three share a row of bolts, and it is inconvenient to disassemble when overhauling the large ring gear. This structure is suitable for small and medium-sized ball mills. Some use two rows of bolts to fix the end cover and the gear ring on the same side of the cylinder flange. It increases the size of the gear outline, and this structure is suitable for large ball mills.
Selection of the material of the large gear of the ball mill: The damage of the large and small gears of the edge transmission ball mill is mainly due to the wear and bending of the tooth surface. Therefore, the ball mill pinion must have sufficient strength, high wear resistance and good processing performance. At present, the material of the large ring gear of the ball mill is usually ZG270~500 and ZG310~570, but it must be normalized before processing to reduce the hardness to HB170~200. The pinion gear is made of 35SiMn, zg45# forging, 40Cr and other materials. After quenching and tempering, its hardness must be higher than that of the ball mill gear HB30-40, which can reach HB220~250.

The price of large and small gears of ball mills: The sizes and materials of large and small gears of different specifications of mills are different, and their prices are also different, so we cannot generalize. Our factory supplies standard gears at wholesale prices for a long time, including tax and excluding tax. Select, free vehicle loading. The price in different periods is different and will fluctuate according to the market price. The final price is subject to the actual quotation.
The characteristics of the large gear of the ball mill produced by our factory:
1. The large gear adopts a unique heat treatment technology, which optimizes the gear structure, improves the hardness, and greatly enhances the wear resistance and impact resistance of the product.
2. The large gear is made of cast steel for rough casting, which ensures the stability of the gear under long-term operation and prolongs the service life.
3. Self-casting blanks, self-processing, standard parts wholesale price supply, can quickly customize a single piece of 35 tons and 40 modulus ball mill large gears can be processed.
