Force Analysis of Main Parts of Jaw Crusher

OCP is a professional manufacturer of jaw crushers. Based on the theory of kinematics and dynamics, our company has analyzed the dynamics and mass balance of jaw crushers. The stress of the four-bar mechanism of the machine hinge and its main components.

Analysis conclusion of jaw crusher:

1. The force condition of the main bearing of the jaw crusher under the full load condition of the machine depends on the structural characteristics of the machine and the state of the crushing force, and the force and moment are not stable; no matter whether the machine is full load or no load Under working conditions, the direction of the maximum force is directed downward to the main bearing seat, which is beneficial to the bearing capacity of the main bearing seat and cover to the crushing force. For the convenience of installation and maintenance, the main bearing seat is determined to be installed horizontally.

2. The lower support of the toggle plate of the jaw crusher no matter whether the machine is under full load or no-load condition, the direction of its maximum force is directed to the lower support of the toggle plate. The bracket seat is determined to be installed horizontally, and the bracket is determined to be installed vertically.

3. The structural size of the flywheel of the jaw crusher can be optimized through dynamic optimization design. Through the counterweight, the unbalanced centrifugal force of the eccentric shaft group can be completely eliminated, but the centrifugal couple moment cannot be completely eliminated at the same time. When the speed fluctuation rate is between 0.020 and 0.025, the value of the flywheel structure size is: the diameter is 1720 mm, the weight is 2880 kg, the flywheel counterweight is 120 kg, and the distance between the center of mass of the counterweight and the center of the flywheel is 700 mm.

Through the above introduction, I believe that everyone has a detailed understanding of the "force analysis of the main parts of the jaw crusher", and I hope it can help you.
