Gearbox vibration in a live axle setup, is this a problem?
Hi,
Looking for some comments from people who have experience with live axle drive systems.
We are powering our drive wheels with a live axle straight from toughbox nano gearboxes, using a rigid coupling from McMaster.
when running the motors, vibration in the motors and gearboxes is evident, beyond what is normal for a CIM motor to vibrate in a standard chain drive.
This is our first year running live axles, so we have no experience with acceptable vibration levels (if any).
Is it normal for a live axle setup to have some vibrations in it? or should it be just as rock solid as a standard setup?
I'm mostly concerned about fatigue in the aluminum chassis surrounding the drive system, and excessive wear on the gears since the load on them is varying and repetetive.
Your comments are very much appreciated.
