What causes excessive vibration?
Vibration can be caused by one or more factors at any given time, the most common being imbalance, misalignment, wear and looseness. Imbalance – A “heavy spot” in a rotating component will cause vibration when the unbalanced weight rotates around the machine’s axis, creating a centrifugal force.
Why is vibration bad?
Whole-body vibration Repeated exposure impacts the spinal discs, and accumulated vibrations can add up – possibly triggering lower back pain and other musculoskeletal disorders.
Why do I need vibration monitoring in my gearbox?
Another application for machine condition monitoring includes gearbox vibration monitoring. In gearboxes, impacting and friction can occur, and a single crack in a gear could cause a slight change in speed once the defective teeth are inside of the load zone.
What kind of problems can be detected by vibration monitoring?
Bearing defects can include excessive loads, true or false brinelling, over heating, reverse loading, normal fatigue failure, corrosion, loose or tight fits, and misalignment, among other potential problems. Another application for machine condition monitoring includes gearbox vibration monitoring.
How are vibrations used to mitigate design problems?
If problems can be predicted, then designs can be modified to mitigate vibration problems before systems are manufactured. Vibrations can also be intentionally introduced into designs to take advantage of benefits of relative mechanical motion and to resonate systems (e.g., scanning microscopy).
What causes vibration when stopped and in drive?
Rough Idle/Vibration when stopped in drive If I put in Neutral its smooth as silk. Very annoying, have replaced the air filter spark plugs spark plug wires replace auto transmission fluid, flushed radiator, replaced PVC Valve, dog bone motor mount, and just for the heck of it the main belt for air/Generator to.
