For a hammer crusher, one of the more important components is the hammer head, followed by the main shaft, so whether it is the hammer head or the main shaft of the hammer crusher, they must undergo rigorous testing and calculation during design and production, such as For the smallest diameter of the hammer crusher spindle
The shape of the shaft is roughly determined because for the spindle, the parts on the shaft and the assembly plan After confirming, the installation sequence is to install the part of the rotor in the middle, then place it on the box body, install the bearing end cover, and then the outer bearing seat. The last two ends are the pulley and the flywheel.
< The shaft diameter required by the diameter of each shaft section is related to the size of the load on the shaft. While the diameter is initially determined, the size and distribution of the bending moment cannot be determined. Therefore, it is not possible to determine the size and distribution of the bending moment on the shaft. The specific load and the stress caused by it are used to determine the diameter of the main shaft. But before the structural design of it, the torque of the main shaft can usually be obtained. Therefore, first estimate the diameter of the required shaft according to the torque of the shaft. And remember what is required at this time. The minimum diameter given out is then according to the assembly plan and positioning requirements of the main shaft, and the diameter of each shaft section is determined one by one. In addition, the shaft section with matching requirements should be as standard as possible, such as the shaft section of the device bearing, the device The shaft section of the part of the standard part should be taken as the corresponding standard diameter and the tolerance of the selected fit.
So every step in the design of the hammer-broken spindle must be strictly measured. In the calculation, the coordination between the various structures must be ensured to determine the minimum diameter of the hammer crusher spindle. It cannot be too large or too small. It is a number that has to be confirmed after many trials.
