What’s the highest Acceleration levels on Gears you have recorded?
Apologies for the lack of posts over the month, it’s been a very busy time with the family.
This post is a short one just inquiring what levels of Acceleration impacting you have seen in the field from a gear set. This is one I came across a couple of months ago.
Summary:
- Vibration data was collected with FMax of 10 KHz and Sample rate of 32,768.
- The shaft rotates at 2990 RPM.
- The gears are small and both have 65 teeth, their function is to transfer drive to an oil pump in a gearbox.
- We recorded a Peak to Peak of 51.67 G’s compared to another identical asset running at 9.176 G’s.
- Two weeks later the gears had a functional failure and stopped doing what they’re were designed to do.
Vibration Data:
This is the 1.3 Second Acceleration Time waveform comparing the suspect unit and an identical unit.
