Eufy Robovac with caries

thingiverse

My Eufy robot vacuum has started to get extremely loud. Upon investigation, it turned out that the gearbox of the front right side brush suffered from tooth loss. The peculiarity in this case is that the outer larger gear rim has helical teeth and the smaller gear rim has normal teeth. To recreate the combined gear, I created the individual gears in FreeCad, because the helical gearing can also be carried out easily here. Since the module size was not recognizable, it was assumed to be 0.5, as was the angle for the inclined teeth, which was included here at 10°. The merging of the two gear parts was then accomplished with Designspark mechanical. Printing was done with 100% filling and a layer height of 0.1mm. The result was usable until the flanks of the helical teeth had to be reworked or cleaned with a key file. Since then, the Robovac has been used again with its original noise level. I had to rework the gears because it didn't last in the long run. The current version is printed in PETG with 100% filling. The "broom gear" is now included and also has the recesses to accommodate the clamping spring. All in all, this combination works and is also smoother.
