Hi all I am using spur pinion and driven gear mechanism to rotate a cylinder. Outer diameter of pinion is 30mm and that of driven gear is 60mm. Mass of cylinder is 500 grams. I have to select a motor of suitable torque for this purpose. Will anybody help me how to calculate torque???
For starters, I think you need the P.D. of both gears, not the O.D. You also need the radius of gyration for the cylinder and a definition of what the load is and the friction it is resisting. Finally, you need a better definition of the problem. For instance, a long small diameter 500g cylinder spinning at constant speed with ball bearings is going to require a lot less torque than a 500g cylinder with no bearings and a large O.D. starting at rest and needing to come up to speed in 0.1 second.
You can use calculation software from WITTENSTEIN for the drive train. Check: http://www.wittenstein-alpha.de/en/cymex.html or for direct download: http://www.wittenstein-engineering.c...ittenstein.exe Have fun.
Hi, I looked at this site. Very interesting! It appears the screenshot of the SW is in German, do they offer a SW version in English??
Hi twebb, In the software there is a tab "Sprache" (if it is in german), where you can select to english (or another language).
