When choosing the raw material of ring gear, we should consider the following principles.

  1. Firstly, the mechanical and physical properties of the steel should meet the requirements of the working conditions to ensure the safety. In general, the working atmosphere is rough, so high axial loads, radial loads and titling loading moments are required. While transmitting through the ring gear, raceway and gears. Therefore, the materials are required to have high tensile, compressive, shear, fatigue strength and quenching hardness, and have sufficient tensile and wear resistance. If the slewing ring is operated in a corrosive atmosphere, the material is also required to have certain corrosion resistance.
  2. Ring billets are required to have good processing and heat treatment processing. During the processing, such as rough rolling, casting, forging, cutting, is likely to be done. During the heat treatment, it is less likely to be overheated, deformed, cracked, decarburized, and has good harden ability and proper quenching and tempering performance.
  3. Under the premise of ensuring the safety, materials with low price and sufficient supply are popular.
  4. Considering the application, light metal materials are widely used to reduce the weight of the parts. For example, Fenghe slewing bearing produces special material with flanged type, which greatly reduces the waste of materials and the weight of the whole machine.
