Hi All,
I don't have an engineering background so at times I have some pretty basic but to me, fundamental questions to answer.
I can see that there cannot be introduced backlash with gearing through a timing pulley belt and very clearly backlash can be an issue when meshing two spur gears. What I cannot conceptualize is whether a spur and worm gear combination can have intrduced backlash or whether helical gear arrangements have introduced backlash.
I guess my primary question is: what gear arrangements have no backlash problems and as a subsidiary question (possibly already answered in the first part), do worm and spur combinations have backlash problems?
Finally, am I right in my assumption that timing belt pulley gearing arrangements have no backlash problems?
Although theorists might say that backlash cannot always be eliminated, I am looking for answers in practical terms.
Happy CNCing
Andy
