Vibration problem
case1n2

The energy of the transient impact was strong enough to excite the natural frequency of the floor resonance.

case1n
Solution:
The problem was solved when the damaged bearing was replaced
with a new one.

 
Problem
The production staff was alerted that the floor at the back of the reel vibrated very powerfully from time to time.

Causes of the problem
In order to determine the reasons and corrective measures, vibration properties and mechanical condition of the reel and its environment were determined by the vibration studies.

These studies indicated that the primary cause of the floor vibration was the damaged bearing of the reel drum.

The outer race of the bearing was broken and was causing transient impact at the rotating frequency of the reel drum.
