Why are the vibrating motors installed in different locations?
The structure of linear vibrating screen is relatively simple, mainly composed of a damping spring, a screen box, motor pedestal, vibration motor, screen, screen frame, a support frame, and the installation method of motor linear vibration shaker can according to different customers, the size of the material characteristics of the site, flexible selection of equipment installed on the top, on both sides of the bottom, etc..
The internal structure of the vibrating motor is the same as that of the ordinary motor. The main difference is that the vibration motor is equipped with a set of adjustable eccentric blocks at each end of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to obtain the exciting force. The vibration motor is more reliable than the ordinary motor in mechanical and electrical aspects.Similarly, the power levels of the vibration motor rotor shaft than the same class of ordinary motor shaft much more thick. This is the main difference in order to meet the requirements of the actual working conditions.
In fact, the vibration of the motor production, clearance between shaft and bearing and the general motors is not the same, must be close coordination between the motor shaft and the bearing clearance, and axial vibration motor and bearing is sliding fit between 0.01--0.015mm gap in maintenance will certainly feel the shaft will produce about string. In fact, the gap coordination has its important role.The vibration motor is by itself to generate high-frequency vibration, vibration, so in the working time, the motor itself will have very high temperature, it is due to the clearance of the existence of expansion in the temperature rise after the vibration of the motor shaft, the shaft and the bearing is expanded to close cooperate to achieve the normal working state, if the gap is not 0.01--0.0115mm, so the vibration of the motor in the working temperature reaches a certain temperature will cause a series of problems, even stopped or burned vibration motor. Therefore, we should pay attention to this problem in the maintenance of vibration motors.

In these problems, the majority of failures are caused by the failure of customers to understand the installation and use of vibrating motors or vibrating screens.
