Changing out for a new gearbox...
I'm looking for some advice on a gearbox and motor for my setup (I am new to motor/gear selection by the way). I've got a vertical lift, operated by a chain drive system. Right now I have a 1hp, 1700rpm motor connected to a 60:1 gearbox. Then there is a 32:13 gear externally. My problem is that the system is not capable of lifting the capacity that I need. The [U]current gearbox[/U] says that it is rated for 0.75hp and has an output torque of 1670lb-in. By my calculations, plus a little extra, I am looking for about double the torque (about 3000lb-in).
My solution is to use a [U]gearbox[/U] that is actually rated for 1hp, which has a ratio of 100:1 and an output torque of 2900lb-in (I know it's not quite the 3000 that I was hoping for, but I at least want to know if I have the right idea). Then to keep a similar operating speed I would drop the external gear ration from 32:13 to something more like 19:13.
Does this actually accomplish anything or does it put the overall performance of the system right back where it was to begin with?
What effects will I see to the system if I do this?
