Gear reducer is the key equipment of vertical mill system. As the task and working conditions of gear reducer are particularly harsh, it needs to run continuously under the conditions of shock, vibration and overload, and its service life is required to be more than 15 years, which requires high reliability. Therefore, the use of vertical mill to the design and manufacture of gear reducer put forward higher requirements.
In the repair process, the gear reducer parts are always at room temperature, without internal stress, thermal deformation, crack, annealing, softening, fracture and crack potential impact. High bond strength, no shedding, no hard point, high surface finish, adjustable hardness. Repairable low carbon steel and low carbon alloy steel, medium carbon steel and medium carbon alloy steel, high carbon steel and high carbon alloy steel, high strength alloy steel, stainless steel, cast steel, cast iron, copper and copper alloy, aluminum and aluminum alloy, zinc and zinc alloy, chromium, nickel, chromium nickel steel and unknown materials.
The repair position is accurate and flexible, and the repair quantity can control the precision. It can also be repaired on site without disassembly. After repair, using tooling grinding technology can accurately restore the size. The reducer is used for grinding cement, coal and other construction, chemical, ceramic and other industrial raw materials. It has a small volume, light weight, small footprint, low power consumption, more than 30% energy saving, long service life and a series of advantages.
