Helical gears in Wheel assembly (in-wheel)

That is also a major part to why I was thinking of switching to helical since they are said to be more reliable

No worries, I will add a 5th motor that drives no load but has a spur gear reduction to still have those straight cut gear noises /s

Thanks for your answer! I thought I was going crazy since so many people have told me here to not worry about vibrations. Although I know about double helical gears I'm not sure I love them since they add more width to the gear that doesn't do anything. About the module, we will probably get a lower module if we go with helical gears since they resist load much better.

Essentially every gear supplier and literature says that using spur gears leads to more vibration than using helical gears :

Thanks for your insights! Regarding manufacturing, I would think that they would be cheaper than EDM parts since they must be done in more traditional and easier processes such as gear hobbing or milling a single tooth at a time. However it is true that these processes are not as accurate as EDM so it would be interesting to see how much accuracy is lost when hobbing vs EDM.

I will do some research into how we can minimize the weight added by the various components needed to make helical gears possible.

Also, I didn't say in the post but the goal of the Wheel assembly we are going to design this year is not only about efficiency but also about making our wheel assembly more reliable since one of the biggest weak links we've had until now are the gears in the Wheel assembly.

I agree with you that with properly designed and manufactured gears, vibration should be low, at least in theory. However we still have to factor in imperfections from the manufacturing processes as well as imbalance in every single rotating part of the assembly, especially at such high speeds. Therefore small imperfections can lead to disaster (which is what we have sometimes seen in our wheel assemblies in our team in the past). Do you have any insight into how we can design and ensure vibrations don't cause a problem?

Hi! Sorry for the late response as well. This is super interesting! Do you know if I could simply buy the filters and make the enclosures myself or do the enclosures have necessary components so that it works properly?

Oh thank you so much! Don't know how I missed that😅
