chain drive

[Red6700]

A gearbox has an output torque of 320"# and the output shaft has a 12 tooth sprocket that chain drives (2) separate shafts with 18 tooth (driven) sprockets. What is the output torque on the (2) driven shafts? Would it be 480"# each, or 240"# each, or? Any response appreciated thanks.

Ratio of the pitch diameters of the sprockets.

Thank-you Ron. If I read you correctly you are saying that the out-put torque on both driven shafts is 480"#.

Depends on the loads on each shaft. You can't have both shafts taking 480 in-lbs or your system would rotate backwards. A better way to put it is, the sum of the torque on both shafts is 480. One could be zero and the other 480, or combination in between that sums to 480.

I am not sure what you mean by 'would rotate backwards' but yes the load is the same on each shaft.... therefore I see now that each shaft has an output torque of 240"#.
Thanks
