Mining machinery transmission gear is an important part, as part of the actuator, the entire operation of mining equipment are required by drive transmission means to achieve the purpose of the operation, due to the constantly engaging with the pinion driven by staggered operation of the entire apparatus, Great gear subject to wear more, therefore, equipment manufacturing for wear resistance, load-bearing, life, fever, weight and bulky gear has a relatively high demand, which makes mining machinery gear processing technology need to be more advanced , can be manufactured in large gear meet these requirements.
For mining machinery gearing requirement is small, lightweight, high efficiency, and the rotation of power, long life, low noise and less heat. In actual production, business-quality gear requirements are very strict, so much gear processing technology is critical to introduce the following mining machinery gear processing technology.
Mining machinery gear processing can be applied to the teeth from grinding roller technology more teeth, etc., but because hobbing generally have higher efficiency, it is recommended that the use of hobbing. Mining machinery gear processing technology is the first gear blanks into the machining, then mainly for further processing to prepare the ground tooth, so that the accuracy gear bore and the end to achieve the basic technical requirements.
The second step is the tooth processing, in order to achieve the required hardness. Then the tooth is finishing, mainly to ensure accurate and reliable positioning, the balance is also more evenly distributed, so as to achieve the purpose of finishing.
Finally, there is the mine mechanical gear heat treatment, so that the large gear structure optimized, improved hardness, wear resistance and impact of their products greatly enhanced.
Great gear application methods in the production of a wide range, its manufacturing process is very strict requirements. Hongxing machine large gears are made of high quality steel as raw materials, sophisticated manufacturing technology, reasonable process out of gear structure, precise size, quality, for the manufacture of high quality mining machinery created a good foundation.
