In this video I took on the complex job of trying to fix a gearbox design a customer has had multiple failures with. This 4 gear set 3 shaft bevel gearbox has a clear weakness involving the support design of the lower bearing and pinion. Rather than try to weld back in the next to nothing piece of cast that keeps breaking I decided to alter the box to take as big of a slug of steel as I could fit to try to maximize the strength and minimize the likely hood of me seeing this job again. Because of all the various angles intersections and fits plus the tight tolerances of multiple bearing fits and having to achieve proper gear lash and mesh on all the gear sets this was a very complicated and time consuming job. I hope you enjoy following along on the redesign and getting to see the simultaneous axis milling to produce the 45deg clearance on my part something I don't think I have ever seen another you tuber do. :-) Also probably not a lot of good footage of drill bits exploding either but you get some of that as a bonus!! Be careful out there but enjoy the shop and keep watching and tell your friends to watch too! Thanks!
Brian and Baily.
