Forged steel wheel set for 500x150 crane crane crown wheel Machine Parts
The wheel group is an important part of the crane. It runs on the rail and bears the dead weight and heavy load of the crane. Crane wheel material should have high strength, high hardness and good wear resistance. At present, 65Mn and C60 are commonly used for forging and rolling wheels. Crane wheels are generally delivered after quenching + tempering. The crane wheel made of 65Mn material is better. 65Mn contains more chemical elements manganese, nickel and copper. Manganese as the main metal element to improve hardenability, the material surface decarbonization tendency is small, after heat treatment, the mechanical properties of the material is good. In addition, manganese is mostly dissolved in ferrite, forming replacement solid solution and strengthening ferrite.
Wheel group bearing bearing adopts corner box structure, through the bolt Angle box is fixed in the trolley frame or the cart end beam on the bending plate, the structure can be used in maintenance to adjust the wheel to ensure that the wheel horizontal deflection and vertical deflection to avoid the wheel nibble rail, corner box structure is widely used in the domestic mature technology. The choice of wheel diameter and material is based on the large supporting force of the wheel under adverse working conditions to ensure that there will not be partial wheel overload. The wheel group bearing bearing adopts 45° partial structure. First, the half ring of the bearing bearing is connected with the dry trolley frame or the end of the cart, and then the whole processing of the half ring and the bearing box ring mating surface, so as to ensure the wheel assembly accuracy and the horizontal and vertical deflection of the wheels. And then install the wheel group, this structure is easy to install and disassemble, high assembly accuracy, stable operation, for the domestic advanced technology in recent years.
