Circular vibrating screen bearings use heat and maintenance reasons

 1. Due to the uneven foundation or the incorrect installation of the spring seat, the abnormal movement of the screen body is caused, causing the vibrating screen to rotate or twist, and the vibration of the vibration exciter bearing is damaged.

Solution: Adjust the base to make it level. When installing, first use the level to measure whether the foundation is level. If the unevenness can be adjusted by adding the pad on the basis.

2. The error of the center of gravity of the vibrating screen is large, causing the abnormal operation of the screen body, which causes the bearing heat to be damaged.
Solution: The ideal working condition of the vibrating screen is that the whole machine runs smoothly and the amplitudes are consistent everywhere. Therefore, it is necessary to strictly control the production and installation accuracy of the products, to ensure that the position of the center of gravity is not offset, and at the same time, as much as possible.
3. The vibration stirrer fixing bolt is loose, or the anti-loose spring washer is not added, causing the vibration source center to vibrate, resulting in damage to the bearing heat.
Solution: The shaker is used for the first time. After 2h and 50h, re-check the fastening bolts and find that the looseness is immediately tightened.
4. If the lubricating oil is improperly selected or filled too much or too little, it will cause the bearing to heat up.
Solution: Under normal circumstances, the lubricating oil should be filled with 2/3 of the lubrication chamber. It is too prone to heat and must be exhausted with exhaust bolts. Generally, in the case of no oil leakage, the vibration device 80-100h is filled with lubricating oil once, the filling is not more than 1kg, and the waste oil is discharged in time.
