The gear reducer is the key equipment of the vertical mill system. Because the mission and working conditions of the gear reducer are particularly bad, it must be operated under continuous shock, vibration, and overload, and the service life requires more than 15 years, and the reliability requirements are particularly high. Therefore, the use of vertical mills puts forward higher requirements for the design and manufacture of gear reducers.
Gear reducer parts are always at room temperature during the repair process, no internal stress, no thermal deformation, cracks, annealing, softening, and no potential effects of breakage or cracking. High bonding strength, no shedding, no hard spots, high surface finish, and adjustable hardness. Suitable for 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 for repair.
The repair position is accurate and flexible, and the repair amount can be controlled with precision. It can also be repaired on-site without disassemble. After the repair, the position can be accurately restored to size by tool grinding technology. The reducer is used to grind cement, coal and other industrial materials such as construction, chemical industry, ceramics, etc. It has a series of advantages such as small size, light weight, small area, low power consumption, energy saving agreement reached more than 30%, and long service life.
