Processing technology of large gears, an important part of mining machinery

The large gear is an important part of equipment such as ball mills, rod mills, grinding mills, rotary kilns, and dryers. Whether it is a small or large equipment, it is inseparable from the transmission function of the large gear. In this article, Shuangwei Heavy Industry will talk about the processing technology of the large gear.

Processing technology of large gears, an important part of mining machinery

The large gear is an important part of the transmission device. As a part of the transmission device, the operation of the entire mining equipment needs to be driven by the transmission device to achieve the purpose of operation. Due to the constant staggered engagement with the pinion gear to drive the operation of the entire equipment, the large gear is also subject to more wear. Therefore, the equipment manufacturing has relatively high requirements for the wear resistance, load-bearing capacity, service life, heat generation, weight and volume of the large gear. This makes the large gear processing technology need to be more advanced and able to manufacture large gears that meet the above requirements.

The requirements of mining machinery for gear transmission devices are small size, light weight, high rotation efficiency and high power, long service life, low noise and low heat generation. In actual production, enterprises have very strict quality requirements for large gears, so the large gear processing technology is very critical. The following introduces the large gear processing technology.

Large gear processing can use a variety of process technologies from gear grinding to gear hobbing, but because gear hobbing generally has higher efficiency, gear hobbing is recommended. The first step in the large gear processing process is to put the gear blank into mechanical processing, which is mainly to prepare the basis for the next step of processing the tooth shape, so that the accuracy of the inner hole and end face of the large gear basically meets the specified technical requirements.

The second step is the processing of the tooth shape to meet the specified hardness requirements. Then there is the fine processing of the tooth shape, which is mainly to make the positioning accurate and reliable, and the excess distribution is relatively uniform, so as to achieve the purpose of fine processing.

Finally, the large gear is heat treated, so that the structure of the large gear is optimized, the hardness is improved, and the wear resistance and impact resistance of the product are greatly enhanced. The application methods of large gears in production are quite extensive, and the processing and manufacturing process is also quite strict. We all use high-quality steel as raw materials, with excellent manufacturing technology. The processed gears have reasonable structures, precise dimensions, and high quality, which has laid a good foundation for manufacturing high-quality mining machinery.
