Bevel Gear For Tatra 813 openRC

thingiverse

This is a gear I conceptualized from scratch, using step drawings from McMaster-Carr parts for the TATRA 813 RC project. To achieve proper mounting depth on The TATRA project, measurements indicate that the total center-to-center shaft distance needs to be precisely 23.5mm. By subtracting the shaft diameter of 6mm from this measurement, you're left with a remaining space of 17.5mm, excluding gear lash. I designed this gear with enough material surrounding M3 nuts for grub screws in mind, so I modified the drawing file to print at 15.7mm instead of the original 17.5mm. To compensate, I added a 1.5mm thick washer behind the gear. Printing my attached STL file would be futile, as it's intended for reference only. Instead, I've provided the Fusion 360 file so you can experiment with printing and testing. Currently, I'm experimenting with Nylon as my print material. I've conducted limited testing on this gear, focusing solely on fitting it into a swing axle and assessing lash. However, I'm eager to see if others can replicate these results and share their findings. My current print settings are as follows: layer height of 0.12mm, Nylon material, hotend temperature at 250C, and bed temperature at 60C. For comparison, the grey and black PLA test prints shown in the image were printed using identical settings, but with a different material.
