What reasons lead to linear vibrating screen motor base crack ?

All users know that the vibration motor is the vibration source of linear vibrating screen , it will bring inconvenience of operation if the vibration motor base cracks and damages. Here are some analysis reasons for you:
1. Too large motor power ,model selection and exciting force which exceed the normal load of vibrating screen, it will cause damage of motor base for long time operation
2. Too thin steel plate thickness design with long time operation will cause crack.
3. There is a problem with steel plate material.
4. Welding quality can not meet the requirements.
5. The installation position of the motor does not conform to the design requirements of the vibration dynamic specifications.

What shall we do to troubleshoot the noise problem of linear vibrating screen?

1.before start-up of linear vibrating screen, we should first check whether the bolts of every part are fastened properly or not, the purpose of fastening bolt is to make the parts more consolidated and reduce the unnecessary extra vibration during operation.

2. add rubber sheet on screen side plate, inlet, outlet and hopper to effectively inhibit the high frequency vibration and reduce the radiated noise. But in the actual production process of rubber ,due to heat and pressure ,it will transform or damage. So please check and replace after using a certain period of time.

3. adopt small elastic modulus ,low impact noise polyurethane sieve plate or rubber sieve plate instead of the punching steel sieve plate , rubber spring instead of steel spring.

4. damping treatment between inside and outside of the bearing housing, bearing roller can be made out to hollow roller or add some damping materials in the interior of the hollow roller.

5. Adopt flexible wheel disk gears instead of steel gears, which using rubber elasticity of gear wheel disk to transfer the torque, absorbing the vibration caused by engaging-in and engaging-out of the gear.
