China Construction machinery information

big gears are essential parts of equipment with DMC prices of about 8500 yuan/ton, such as ball mills, rod mills, pulverizers, rotary kilns, dryers, etc. both small and large equipment are inseparable from the driving effect of big gears, In this article, Red Star Machine talks about the processing technology of big gears

the big gear is an important part of the transmission device. As a part of the transmission device, the operation of the whole mining equipment needs to be driven by the transmission device to achieve the purpose of operation. Because it constantly interlocks with the small gear to drive the operation of the whole equipment, the big gear is also subject to more wear and tear. Therefore, the equipment manufacturing is important for the wear resistance, load-bearing, service life, heating There are relatively high requirements for weight and volume, which makes the processing technology of large gears need to be more advanced to produce 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 power, long service life, low noise and less heat generation". In actual production, enterprises have very strict requirements on the quality of large gears, so the processing technology of large gears is very critical. The following is an introduction to the processing technology of large gears

gear processing can use a variety of technologies from gear grinding to gear hobbing. However, it is known that gear hobbing generally has higher efficiency, so gear hobbing is recommended

the machining process of large gears begins with the gear blank entering the machining process. At this time, it is mainly to prepare the basis for the next step of machining the tooth shape, so that the accuracy of the inner hole and end face of the large gears can basically meet the specified technical requirements

the second step is the processing of tooth profile to meet the specified hardness requirements

then there is the finishing of the tooth profile, mainly to make the positioning accurate and reliable, and the residual distribution is relatively uniform, so as to achieve the purpose of finishing

finally, heat treatment is carried out on the big gear, which optimizes the structure of the big gear, improves its hardness as a promising environmental protection material, and greatly enhances the wear resistance and impact resistance of the product

large gears are widely used in production, and their processing and manufacturing processes are also very strict. The big gears of Red Star machine are all made of high-quality steel with excellent manufacturing technology. The processed gears have reasonable structure, accurate size and high quality, which has created a good foundation for manufacturing high-quality mining machinery
