Direct belt drive

Postby Paradox1559 » Sun Aug 26, 2018 1:34 pm

I've been toying around quite a bit with minibikes, and farm equipment. I find myself constantly amazed by belt tensioner clutch drives. Has anyone tried a dual belt system tied into a jackshaft? I'm going to be trying it regardless, it's incredibly simple, and adaptable. It might even be slightly dangerous.

Hi I have a big lawnmower that is a walk behind, this has a double rotor blades and gearbox 4 gears + reverse. this has a clutch which is single V belt and jocky pulley. this mower is very powerful and will pull a trailer with me on it + 1/2 ton of sand. Just a point to remember the belt is a cotton covered V belt. This I presume makes it easy to slip when the tension is released. Another point to think about is engine braking, when wheel drives engine all the force is then on the jocky pulley.

My first "bike" used a belt tensioner for a clutch. At age 14 my twin brother and I stick welded an engine mount to a 20 bicycle frame. Worked like a charm. And we were happy boys.

Well, I just need to mount my motor into my frame and I can get started with my "transmission". My bike should be moving within a month.
