I know there is a ton of info out there on belt conversions for gearhead mills but mine isn’t like any I have seen,at least not on the surface, but the internals may all be basically the same.
I have a 1-1/2 hp 3 phase motor im going to install on it to replace the 3/4 hp motor, and since I will have variable speed I want to do away with the sloppy noisy gears that I believe are causing horrible finishes. I know the much bigger motor is not necessary and over kill, but it was free so I’m not going to buy a 3 phase 3/4.
My machine is a g0791 lathe/mill combo. I know rigidity was a problem before but anyone who thinks that rigidity is the cause of the horrible finish I will assure you that is not the case. I skinned the base with 1/2 steel plate and have a heavy I beam welded to that that is secured to the concrete below and the base and column are both filled with my own mixture of epoxy granite. I might add gussets to the column but don’t see much benefit bc the mods I’ve done so far have blew me away with the results. But the gearhead has so much slop, it bangs around , and twice I’ve had it lock up when the gears didn’t mesh properly. I had to switch from reverse and forward multiple time real fast to get it to unlock and that was a really uneasy feeling.
So I’m going to replace all the gears with a single speed belt system but with a variable speed controlled motor, so I need recommendations on where to start and what is the best way to go about it? Like pilot size and belt types? Should I go with a cogged belt with cogged timing pukka or just v belts? Any help is welcome. Thanks
