Am I asking for trouble putting the one-way bearing usually working at under 3000 RPM into an application of working at 30,000 RPM?
I'm working on a rotorcraft project of my own design and want to use a one-way bearing in the drive train. The application used by the mfgr of the RC electric heli the motor is used in is to put the one-way bearing on the driven gear (i.e. the main rotor
gear...I'm using the motor from an 500 class electric RC heli to turn a 19 tooth module 1 (19mm Pitch Diameter) pinion at 30K RPM. For space-saving and other reasons, I want to put the bearing inside the pinion instead of on the main rotor gear. I've
seen no RPM limitation listed for the one-way bearing used in the RC heli. The gear-reduction ratio on it is 134/12, so at a motor/pinion speed of 30K rpm the main rotor gear would turn at 2687 RPM. I have seen, however speed (RPM) limitations on other
sprag clutches. So, am I asking for trouble putting the one-way bearing usually working at under 3000 RPM into an application of working at 30K RPM?
