Crankshaft Run Out
Crankshaft Run Out
(OP)
Hi,
I am more electrical than mechanical, I have an application which need to be modified, the current machine checks for axial and radial runout on a crankshatf, specifically on something that is called time gear or time cogwheel (sorry but english is not my native language) the case is that this cogwheel has several teeth which are coming out of the vise with several defects like if it hasn't gone through this vise (you can see on a tooth that is not uniform or terminated). Can someone explain what exactly is axial/radial runout on a cogwheel crakshaft and how is measured. Thanks
JM

RE: Crankshaft Run Out
Try a websearch. I ran across several sites with information. One actually showed a movie (note: this is aviation related, but presumably the same):

It appears you would rotate the shaft, and measure how far in/out or back/forth the surfaces move with a dial indicator.
