Use of High-Strength Gears on Drivetrain

I’m redesigning my drivetrain from a chain-and-sprocket system into a geared one. Should I use high-strength gears, regular gears, or a mix of both.

I would personally use low strength gears because they take up less space (and might have less friction? Not sure)

If you have the space I’d use high strength gears, so when your pushing something they don’t start skipping and you lose energy, I wouldn’t use high strength shafts though, those supply a larger amount of friction than low strength shafts and they’re not really necessary.

im p sure that hs gears causing more friction is a myth. however using hs axles over ls axles definitely causes more friction.

if you have space, you should, but at the same time you don’t wanna purposely re-design the drive base to have wider wheel bays just because you wanna use hs gears. if you have other reasons for widening the wheel bay, and the usability of HS gears is just an add-on, thats fine.

That’s true, if it’s working and don’t really need to change it the don’t.

Which set do you have? If you have a V5 Kit, I don’t think any of them have normal gears.

Here’s what I originally planned to build with all HS gears in order to prevent any slipping and potential gears sliding due to weakened shaft collars

From what I’m seeing, why cant you directly link the motors to the wheels?
Is there something not cadded in?

this is not related to the motor/gear setup, but it is possible to have just 1 collar and reduce the amount of friction by moving the collar to the inside.

Yes placing a shaft collar on the inside of the two cchan shown will prevent the axle from coming out of the motor or the bearings. To do this you do need to fill the remainder of the shaft (that is in between the two halves of that side of the drive), with spacers to prevent the single shaft collar from shifting around.

I want the motors as far away from the edges of the robot as possible. I might go direct drive on the front wheels, but the back wheel needs to be as far away as possible.

Just out of curiosity, but why do you want your motors as far away from the edges as possible?

Sometimes people can have claws of some type that could potentially run into our robot and break it. It’s more of a security measure rather than other means

It is not like Robot Wars, where Sir Killalot, Matilda, Shunt, and Dead Metal will shred you to pieces…

Some aluminum flats, plexi, or mesh should give you plenty of protection.

But I like your security measure thinking.
