Re: Chain Heat Testing
When the chain is engaged with the sprocket it is effected by the chordal action (polygon effect). During engagement one of the points of that polygon pushes, causing the chain to rise and then drop back down into it's engaged position. This actually causes speed variation in the chain. It slows down and speeds up at these engagement points. I think that this is where most of the heat originates. By increasing the number of teeth in the sprocket, the number of polygon points are increased and the chordal action is decreased.
Currently I am running a 16 tooth 630 which is the largest 630 I can fit due to interference with the clutch pushrod. I could fit a 20 tooth 530 chain but I suspect it would have to be dual chains to take the load.
The question is if it will be enough of a change to make a difference in the chordal action and in turn the heat generated.
I need to get this master link BS sorted it out or try to first because it is in fact our only area of issue afterall.
