As everyone knows, the rack of the crusher machine needs to withstand the periodically dynamic pressure of the motion components when the crusher machine is in the no-load operation. The vibration force of the rack brought by the inertial force can be used to optimize the balance to reduce or eliminate the dynamic pressure of the motion components on the rack. What is the dynamic force is like when the crusher machine is in the load conditions? The experts of Henan Hongxing Mining have carried out the dynamic analysis about the motion mechanism of the crusher machine in this kind of working conditions. You can use the corresponding dynamic analysis program to obtain the stress state of the main components of the revolute four-bar mechanism of the crusher machine in the load conditions. In addition, the 3D modeling software has been used to establish a three-dimensional model of the motion mechanism of the crusher machine. We can get the following conclusions.
The first is the stress analysis about the crank. The crank not only suffers from the action force of the weight of the eccentric part of the eccentric shaft. In addition, the crank also suffers from the constraint reaction force of the kinematic pair and the hinge kinematic pair.
The second is the stress analysis of the connecting rod (moving jaw). In a crushing cycle, the crushing process occurs when the angel of the spindle is between 60 degrees to 240 degrees. The size of the crushing force and the acting point size change with the turning angel of the crank. The peak value of the crushing force is at the 2/5 height of the lower part of the crushing cavity.
The third is the stress analysis of the elbow board. In the motion process of the elbow board, the inertia force and moment of inertia will be produced. Since the value of the inertia force and the moment of the inertia are too small, they can be ignored. The elbow board can be regarded as a two-force member which also suffers from the hinge constraint forces of the kinematic pair.
