DIN 5482 Splines - Is there a resource to determine lash?
DIN 5482 Splines - Is there a resource to determine lash?
(OP)
I've got existing spline connections which I am told have excessive lash. What I can't seem to figure out is if lash is somehow included in the DIN standard through tooth thickness and so on, or if the final fit is up to the original engineer to determine and specify through those same DIN parameters. The shaft is a commercial product, but the gear is strictly custom.
I'm afraid my knowledge of splines is light, so any insight into this issue would be most helpful.

DIN 5480 defines 3 types of centering, thats
- on the flanks
- on inner dia
- on outer dia
With the second and third, a lash or play between the gearflanks is functionally necessary.
Any lash or play within the spline connection is then a function of the above choice, through the manuf. dimensions.

We've sent some samples to a local gear cutter, along with the pin measurements and other critical dims from the DIN standard which I just purchased. We'll see what he comes up with, and I'll report back when I get it.
