A Bumpy ride

At Indrotech we feel it our duty to educate the industry on what faults we look for on a problematic driveshaft and how and why we rectify it.

Here is a fault that we find with a typical truck drive shafts.

The fault either comes from neglect to service it, normal wear and tear and believe it or not, even as new from the Original Manufacturer. This fault creates a massive vibration causing failure to the shaft components like; universal joints, centre bearings and even the driveshaft itself. That’s why we always stress that shafts need to run geometrically true to avoid this from happening.

Our first step is to look at the overall concentricity of the assembly starting from the straightness of the tube to the concentricity of the other components welded to either end of the tube. It does get technical and tedious to fix but it must be right, otherwise we come up with the problem that you saw in the video.

The benefit of our procedures is reducing this obvious runout down to 4 thousandths of an inch, equivalent to 1/10th of a millimetre. This is a standard service we practice within our Manufacturing Process let alone our Balancing Procedure.

This procedure helps with our final balancing process that in turn eliminates any vibration in the truck that is caused by the driveshaft. In the video we are running the shaft only at a couple of hundred RPM, imagine what effect it would have running at 3 or 4 thousand RPM. It would be dangerous on the road and more than just a bumpy ride for the driver; it could be catastrophic!

Please refer to our last post so you can see how a shaft, whether a single piece, 2 piece, 3 piece or 4 piece should run. 3 piece driveshaft balancing

Quality guaranteed, Certificate of Balance upon request.

Dynamic Balancing of high speed rotating components increases bearing life, achieves smoother running conditions, increases service life and enhances the quality of the finished product.

To ensure quality workmanship, Indrotech periodically service and calibrate all balancing machines to continue to provide optimal productivity, accuracy and reliability.
