I’m on team 4926 GalacTech and this off-season we are attempting to build a swerve drive. Although I will probably post the final design on here for feedback when it is done, I would appreciate some of your input on the axial/thrust loads cause by bevel gears (our current path is coaxial).
Through some calculations from a PDF I found online, I determined the axial load from the vex bevel gears and a NEO with a 3:1 reduction is about 48.6 N on the bearing that will be containing the gear. My calculations and the PDF I got my formulas from are attached (Please let me know if any part of my calculations are unclear). This result is also fairly close to the 50 N force that was calculated by the KHK gear calculator. Does this seem like a reasonable result?
Also, would a typical andymark flanged 1/2 inch hex bearing be able to take this kind of axial load? I couldn’t find any axial load data from the andymark or vex websites on this type of bearing but maybe some of you have some personal experience.
If the bearing can’t support the axial load, I will probably just put a washer between the thrust bearing and radial bearing that spreads the thrust load across the flange of the bearing rather than the inner race.
Thanks for your help!!
