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.
