I'm gonna say between the torque and the RPM the small inner circle that holds the spider together gave way. Allowing each individual part to slide its way towards outside ending up like a pile of eraser shavings, which prob didn't take too long. A tougher material +, easing edges +, little more material in center to hold together +. I didn't finish engineering school, but I did stay in a Holiday Inn on way to LS.
I learn so much from this site. Before today I had always thought this was a "Guido Coupling." Go figure.....
Are you suggesting that you use this type?The diameter of the 3 driven pins on that with the package size constraint you're working with is going to be a problem. If you "fit" that concept into the area you're working with the pins are only going to be about .375 dia? Not enough for the load you're trying to put thru it. You could fit a paddle shape like is on the Busa motorcycle alot easier but I still doubt it would carry the load considering the reduced diameter you're trying to fit it into.I think Carl has a good thought with the wimpy little ring in the middle on your current part failing and then the pads floating around and getting squished out into the grinder
U-joints...... Two little nibs that are loaded in almost perfect shear and fully supported by the bearing surrounding them. The problem with this is the flexible coupling allows the pins to be in bending unlike the u-joint.Basically I'm just comparing the factory Giubo on the Busa with the envelope you have to work in. The diameter is the key.
There is no gudio on a busa. A cushion drive,yes, but not a guido.
Polar moment of inertia will be lower.
