Morning all,

It's been a while. We have a gearbox that has been chewing up worms. Turns out the supplier has not been hardening the worm!! While this is not the problem it is easily remedied.

My problem is after 20 odd years of manufacturing this gearbox we have been told that putting the worm/worm wheel as the first stage of reduction is not recommended!

Anyone have any ideas on this or any websites that explain the whys etc?

Cheers

Colin
