ZPG-LC-500X1500 wheel type crusher rotor and its reducer structure design
Abstract: The design is ZPG-LC-500X1500 wheel type crusher rotor and its reducer structure design. It mainly content the structure design of the reducer and the tooth roll. So i start from the reducer. First, i determine the levels of transmission ration so as to have the torque and power of every shafts, then i design the corresponding gears. After these, i roughly estimate the length and width in order to design the engine base. Having the size of engine base, it is easy to design the other parts and components of the crusher. Among these, include the design of each axis and tooth plate and the choice of bearings and keys. One of the most important is the design of the shafts. For example, to the high-speed shaft, we choose the 40Cr as material because it can improve its durability. In addition,during the design, i also calculate and check the maximum service time of the components. There is no doubt that it plays an important role in improving the service time of crusher. I believe there are still many questions remained to be solved by our practice.
Key words: wheel type crusher; reducer; structure; calculate
