I just posted a thread about building a 22' diameter revolving turntable. If possible, i would like to power the thing with an
electric motor. After doing some research on this site in previous threads, i still have no idea how much horsepower, torque
etc. i would need to spin the revolve. Another question thats bugging me:
If i have a motor that puts out 2000 rpms (that seems to be average) how do i use that massive amount of rotation to spin the small tire that drives my turntable? do i need a gears/belts/pulleys to reduce the rpms to a number that i can use? If i put it directly on the revolve without gear reduction, will the weight of the revolve make the motor burn out?
I was reading up on some worm gear set
ups. If i hook up the motor drive to the worm, the worm to the gear, then the gear to the tire, would this be the simplest way to power this revolve? I know worm gears greatly reduce rpms, but do they steal torque as well?
Can anyone help me?
