CIM Motor Shaft Bending Moment
We're working on a design project, and this will require having the pinion gear on a CIM placed far out on the shaft before engaging with the gear in a gear box. I know that bending moments are undesirable on motor shafts, but most gearboxes place some bending load on the motor output (torque divided by the cosine of the pressure angle times the pitch radius) unless there's an equally spaced distribution of evenly loaded output gears and/or you're running a planetary gear box.
Does anyone have any reference for the maximum allowable bending moment on a CIM? I can't find anything like that on the application drawing, but it has to be able to take some amount of bending, or all interfacing gear boxes would need to be planetary.
Thanks.

To put it simply, its clearly become this. The teams that can score a lot, do well. Rather shocking, isn't it? It doesn't matter if you're a shooter, dumper, power dumper, gravity dumper, spitter, flinger, dunker, shumper, barfer, dropper, or whatchamacallit. Points are points. - Looking Forward [more]
