Maintenance of vibration-producing exciters
In order to ensure that the bearings and other components that make up rotating machinery can be used for a long time, it is common practice to reduce the vibrations generated by the rotary motion. Dynamic balance correction in the maintenance process maintains stable operation over a long period of time. However, some machines, known as vibratory machines, deliberately cause vibrations to carry products, and the maintenance of these machines will be introduced in this article.
Disassembling and inspecting a vibratory machine
No abnormalities were found when the lid was opened. Further dismantling of individual parts.
Condition of the shaker shaft
Repairing defective part
Repair methods were considered based on a comprehensive assessment of the characteristics of the machine intended to cause vibration and the loading conditions of the mating parts obtained from the inspection of the parts. Repair by plating and repair by weld overlay were considered to be the most effective and repairs were carried out on the respective parts.
Assembly after repair
Appropriate repairs are also carried out on special-purpose machines
Normally, the aim is to achieve long-term stable operation by suppressing vibrations, but this time we have introduced the maintenance of machines that intentionally cause vibrations. By carrying out repairs to fitted parts that take their characteristics into account, stable operation can be achieved even for machines that constantly generate vibrations.
