Diagram for input shaft quote.
Well I have finally purchased my first major part for my DIY Motion Control Rig. It's a worm gear box which will be part of the Pan Tilt Head System. The pictures I took with my phone make it look much larger the it actually is. The gearbox weighs about 1.2kg which seems fairly light compared to some of the rotary tables out there used for the same setup.
It was about $150 AUS and if it's works the way I hope, I will buy another one for a second axis. The gear box ratio is 60:1 (60 motor revs = 1 output shaft rev) to ensure I have enough resolution in my camera pans or tilts. There seems to be a bit of backlash but I will need to run some tests before I know if it's of any concern.
I still need to make an adapter shaft between the motor an the gearbox. I'm getting a quote from a local machine shop for that.
I'm thinking of going for a nema23 stepper with this setup, but still need to do a bit more research. Can't wait to try this out!
