splines are tight in bevel gear
splines are tight in bevel gear
(OP)
Dear all
we got a problem in axle shaft. some of the axle shafts are tight in bevel and in some bevel is not enetering.axles are induction hardened.is there any way we can repair splines which are not entering.or tight.
Regards

I'd investigate for the "tight" spots with dykem ( thick ) or black Sharpie ( thinnner ) etc.
To see if a little deburring is all that is required, or some significant distortion is the problem.

You don't know enough now to determine if some of your bevels are too large (and won't go into properly made in-tolerance slots), some of the slots are too small (and won't allow properly made, in-tolerance bevels to fit inside deep enough), or only a few too-small slots won't let a few too-large bevels to fit in.
So MEASURE THE GROUPS of many parts and figure out what is changing. Basic root cause analysis - Don;t build an assembly without it! Then, figure out what is causing the difference in machining (tool wear, poor fit in the grinder/gear lathe, bad casting or bad bearing or bad bearing tolerance or whatever) that is causing your parts to go out of tolerance.
Or, fix the requirements and require more tightly machined accuracy: make you tolerances closer.
Now, for the short term, AFTER you have decided what the real fix will be, you can salvage some of your parts by fitting too-big bevels into assemblies with too-big-slots, and put the too-small bevels into correct-sized slots, etc. But remember, that's what caused the tremendous expense of the first mass-produced muskets and rifles: hand-fitting and hand-carving machine parts is very slow, very expensive, and means each assembly is unique and can't be repaired with nornal parts later.
