Hello.
I am trying to calc the output torque of a gear reducer consisting of a bunch of spur, pinion gears in the gear train. Assuming 100% gear efficiency, is the output torque simply a ratio: Torque(in) x RPM(in)/RPM(out)= Torque(out)? I know Torque(in)= 34.29 g-cm @ 4,000 rpm I know RMP (out)= .71 rpm Is there a typical efficiency for a well design gear train I can use or are there just too many variables? Strictly for a coarse estimate of output torque. Thanks,
|

Is it just me, or assuming 100% effeciency, have you answered the calc problem? in/out x torque 4000/.71 = 5633.8028 x torque..... I tend to use 75% efficiency as a "safety factor" coverage. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them. |
