If you have a motor running at a higher torque than the output (machine), shouldn't the pinion be on the machine then to make up for the higher torque of the motor?
Acme thread? an NC threaded bolt works just fine for take-up adjustment. Also, your calculation is hard to follow where does the 12 (4000) come from? Does it really matter what the diameter of the small pulley so long as there is a 2:1 ratio between both pulleys it could be like 6" small 12" larger as an example. I would be more concerned about finding a belt length to suit that is readily available to work with a 20" c/c distance that you make note of. There may not be a suitabe belt lenght for a 5" diameter to 10" diameter pulley setup. While some of this is good information you have missed a lot of steps or missed giving complete information. No such thing as a 6.5 hp motor 7.5 would be the next available to your belts need to be sized to 7.5 HP not 6.5. Check the NEMA frames. sorry but 12(4000)/3.1416/3600 is not 5.09 its 4.24". There is just so much wrong about this video
thanks for the videoBut I did not understand the step of calculating the pitch diameter ,where is the number 12 & 4000 come from.
I just want to know if , there is a calculation for the machine shaft..

I just want to now how quarter turn belt drive work
thanks very much really really i needed this video thanks again...
12(4000)? from were sir
It was very interesting, thank you
Nice video
