Hello
I am interested in using G5549 Bench Mandrels - 5/8", Ball Bearing. And, the G2533 Motor 1 HP Single-Phase 3450 RPM TEFC 110V/220V. Or, the G2532 Motor 1 HP Single-Phase 1725 RPM TEFC 110V/220V. Grizzly hardware. I have not decided if torque or speed is the way to go. However, I don't know what size pulleys should be attached to the motor, in order to maintain RPM at the mandrel or in the reverse. Other than size, what difference is there between 2, 4, 5" double V pulleys. Guessing the purpose is to change speed between motor and mandrel. You really can't change RPM just by changing the size of pulley can you? SFPM changes with diameter in relation to a set RPM, but how would SFPM play into turning two different sized diameters?(pulleys) Don't see how SFPM would have anything to do with pulley stacks. I feel like an idiot here, 'cause I'm sure this would've been something covered in a high school education not learned Thank You for any assistance. |

heres a quick example , motor with 1750 rpm with 2 inch puley and mandrel with 2 inch pulley in this scenario the wheel on the mandrel will be 1750 rpm same 1750 with 2 inch pulley but 1 inch on mandrel in this scenario the wheel on mandrel will be 3500 rpm same size pulleys =same rpm smaller on motor and bigger on mandrel end =slower rpm on mandrel bigger on motor and smaller on mandrel end = faster rpm on mandrel here a link you can use to find exact ratio and also to find the size of belt you need http://www.csgnetwork.com/pulleybeltcalc.html |

Think of it this way...say the 4" motor pulley moves one rev, which say moves the belt 6" (or whatever the circumference is) along its path. It also moves 6" at the 2" tool pulley, but since the 2" pulley is only half as big, it has to move more than one rev...two revs to be exact, since it is half as big as the 4". Hope that wasn't too involved. In short, if you want the same revs, use the same size pulley at both ends. |
