The Liner shaker motor using two two separately driven eccentric shaft , in order to obtain a straight line shapes . Avoid the use of high-precision gear rotor forced the two excitation linking practices , so that the structure is greatly simplified.
In the ideal case ,such as the system of two identical motor characteristics , the fulcrum of the stiffness and damping are equal, nor phase exists at startup , two eccentric block synchronization reversal, can achieve linear vibration type . But in fact, because the two are not identical , and start the motor characteristics and other reasons , the two eccentric operation , it is not strictly maintain the relative position shown in Figure 2-9 , when the two eccentric centrifugal force can not be generated by Figure 2-9 superposition manner and offset to produce an unbalanced force , so that the whole screen box spring on the support movement and generate additional swing. It is due to this move and swing. Also the two eccentric automatically follow each other until they reach reverse synchronous rotation . This process is called self- synchronization process.
The shale shaker is a important equipment in the solid control equipment.Because two asynchronous motor for rotating the normal synchronization process, a sudden stop a willfully motor power.this motor sometimes can not stop turning , it is still a long term with negative 2-axis synchronous rotation . Then sieve pinch inevitable swing , is no longer a stable linear vibration . This is because a q mJ power from the motor shaft , which can be obtained during the vibration part of the energy to overcome the friction torque shaft , but its speed - fixed somewhat reduced, which necessarily and m: between emergence phase angle A. , The question arose AF force . So, still get to follow the surface of the long-term autocorrelation synchronous rotation . If the motor after a power failure during vibration energy can not be obtained in overcoming the friction torque shaft , the motor will slow down gradually . And stops rotating .

Brightway Design, installation location away from the mud shaker centroid distance, its main purpose is to make the sieve on the swing axis moment of inertia is small, that is to take reduced, Increasing j. Measures to improve the running stability.
