Belt to chain single primary reduction stage?

Post by socalfusions » May 08 2012 7:56pm

Can anyone explain what kind of applications would use or benefit from this type of reduction system? What is the reasoning to go from a belt to a chain and what benefits does it entail?

What specifically are you talking about? Are you saying a motor drives a belt which in turn drives a sprocket that has a chain on it? I've seen that arrangement. Are you asking why a belt was used for the first stage and why a chain for the second?
Belts are generally preferable to chains because they are cleaner, but you can't break a belt and you can a chain. So, some situations don't allow belts.

A belt system is also quieter, so especially on the first stage that is of interest.
New to endless-sphere? Notice a lot of signatures recommending Ebikes.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.

Which you choose depends on the speed of the chain, above a certain number of meters per second chains become very noisey so a belt would be prefereable, this is why they are chosen for the first stage reduction on high rpm rc motors. for example a chain with an half inch pitch is limited to about 3750 rpm on sprocket sizes between 17 and 25 teeth.
