Hey all
I've been lurking for quite a long time and tinkering with my first ebike build (gng gen1 on a cheapish hardtail Jamis). I've been a huge lurker on the primary chain conversion thread and am planning to swap out my belt drive in the near future.
I was discussing my plans for a chain conversion with a buddy of mine who has a background in machine building/integration and he raised an idea that I haven't seen on here yet.
I'm a jack of all trades and master of none type...definitely no expert, so I'm posting here for the ES expert opinion.
His idea was to CNC or print a toothed gear drive sprocket that sleeves over the original belt sprocket and replace the main drive pulley with a larger gear for a clock-like toothed gear-on-gear drive.
Has anyone tried this/thought of this before, or has posted anything about it? I would imagine it would be louder than the belt drive but I would assume it would be a bit quieter than a chain. And direct gear on gear would make for awesome torque delivery without tensioners or chains to break or stretch.
I have a super prototyping facility at work with the ability to cnc or 3d print any plastics or metals - we have all types of printers
. I was originally planning on making some lightningrod-esk type upper plates and a new drive sprocket and chain pulley, but now I'm wondering if the toothed gear setup would be of any added benefit.
Seems like it would be massive strength with little wear, but I wanted your opinions. Anyone able to enlighten me? Is this not how cart drives work?
Thanks folks! I appreciate all the great info here! Many of you have already unknowingly helped me out of a few pickles
