What role does the rotor of the sand making machine play in the work of the sand making machine? Let’s take a small example to explain it! If the rotor type of the sand making machine you selected is not correct, it may affect the quality and efficiency of the production line of the sand making machine. Sometimes the motor of the sand making machine will be burnt down in severe cases. The trouble is big. So what do we do to do our best to protect the rotor of the sand making machine!
First: choose the right type when selecting the rotor bearing model. Double-row radial spherical roller bearings have the advantages of strong bearing capacity and good self-aligning performance, so they are often used as rotor bearings in the selection. In addition, the calculated life of the selected bearing should be 5000~10000h.
Second: to improve the bearing condition of the sand making machine bearings. The impact load acting on the bearing depends on the amount of impulse acting on the rotor and the support flexibility of the bearing housing. Increasing the support flexibility of the bearing housing will reduce the impact load on the bearing. To this end, we can add a rubber plate of appropriate thickness between the bearing housing and the support frame to improve the support flexibility of the bearing housing. Due to the addition of the rubber sheet, the support flexibility is increased, thereby absorbing a part of the vibration energy, improving the bearing condition of the bearing and achieving the purpose of prolonging the service life.
The role of the sand making machine rotor can be large or small, you must pay attention to the normal use of the process, regular cleaning of the sand making machine, these have a great influence on extending the life of the sand making machine.
