Impact load caused by feeding in rolling bearing of explosion proof vibration motor

The running track of explosion-proof vibration motor is that the vibration of vibration body is produced by two groups of excitation systems, and its vibration form is called compound vibration. Generally, there are two types of dual frequency compound and double frequency compound. For some vibration screening equipment with special performance, two kinds of explosion-proof vibration motors with different rotating speeds are installed at the feed end and the discharge end of the screening machine, which makes the feeding end vibrate at a large amplitude and low frequency, and outputs the materials at the same time. There are small amplitude and high frequency vibration at the end, and two kinds of vibration overlap in the middle of the screen, which makes the screen play a more effective role in screening.

Explosion proof vibration motors sometimes fail. I don't know if you found them. In fact, most of the faults are caused by the wrong operation of the explosion-proof vibration motor. So, what to do when the explosion-proof vibration motor fails? Let's take a look at the following.
 
Unreasonable bearing selection.
 
In the working process of the rolling bearing of the explosion-proof vibration motor, the impact load caused by feeding is large, the centrifugal force and centrifugal acceleration produced by the high-speed rotation of the eccentric block are also large, and there are more dust in the working environment. More, so the type of bearing used, the limit speed is 2. The requirements of fitting size, clearance and self-lubricating performance are relatively high. Under such bad working conditions, ordinary bearings are easy to be damaged. If the bearing is not selected correctly in the initial design, the bearing life will be shortened.

method:
 
Special bearings are used for explosion-proof vibration motors. The commonly used explosion-proof vibration motor bearings are cylindrical roller bearings and self-aligning roller bearings. Cylindrical roller bearing has large radial bearing capacity, high limit speed and strong bearing capacity for dynamic and static loads.
