Vibration has long been a concern for engineers. For a machine to function smoothly and efficiently, which is every engineer’s desire, the use of vibration isolators is critical. The thing is, all machines with moving parts will vibrate to some degree. Even the laptop that you think is working smoothly and silently also vibrates. You may not notice some of these vibrations because they vary significantly from one machine to the other.
Vibration can create loads of problems for the user, company, and engineer. It can develop a form of imbalance, create excess noise, and even lead to damage and loss of functionality. In a company where increased productivity is of utmost importance, having a tool that is unable to function to capacity can lead to loss of revenue. On the other hand, a well-designed machine with adequate vibration solutions incorporated will contribute to smoother operations and better production results.
Examples of effective vibration solutions can be found through Isolation Technology. If vibration has started to become a problem for your company’s production and maintenance, the following information will help.
Factors Responsible for Sudden Vibration in Mechanical Devices
There are many manufacturers that will create a fantastic product only to install a defective isolator in it. This is why vibration issues are rarely traced back to the machinery itself, even if mechanical devices appear to starts vibrating out of the blue. Instead, the cause of the vibration is more likely due to the issues below.
- Connection Issue
No matter how tight your bolts and screws are, they will eventually become loose after some time. It happens a lot. In short, bearings can also loosen in situations where they are not well tightened or once you have made use of them for a certain period. The list of things that can cause vibration due to a poor connection is a long one. Even cracked welds can lead to vibration of mechanical devices.
- Imbalance of the Machine
If you are dealing with a mechanical device that rotates, ensure the machine has proper balance. When there is an imbalance, a centrifugal force will be automatically formed, thus creating vibration. And the higher the speed of rotation of the said mechanical device, the higher the vibration would be.
- Wear of the Machine
When dealing with a machine that rotates, have in mind that vibration can occur at any time. It can also become more severe as the damage worsens. For instance, the bearing in the machine can become pitted after using the device for a certain period.
What to Consider Before Choosing Isolating Vibrations
Before choosing some form of vibration isolators, there are things one must consider. First, you have to pay attention to the weight and size of the mechanical device you want to isolate. Another factor to consider is the center of gravity. You may need isolating materials with certain load capacity, so you must be able to determine the center of gravity and other factors before choosing your isolating material.
The main point is for engineers and users to acknowledge the fact that no mechanical device is beyond the problem of vibration. All machines vibrate, most especially when they have been in use for quite a long time. But, you shouldn’t allow the vibration to persist as an unavoidable factor. More serious issues can result if you are not proactive. Use the right isolating material to prevent vibration and further damage to your machine and you’ll have solved a potentially costly issue.
