Synthetic cycle machine problem
Thread Content
Our synthetic cycle machine replaces the crankshaft due to wear. The original crankshaft is made of ductile iron, the new crankshaft is made of carbon steel forgings, and the counterweight iron is still the original one. Is it okay to assemble it this way/can it also be used for balance experiments? Asked for advice
Haha, it’s not okay to worry about the weight iron. Is it still balanced if the ductile iron is replaced with forgings?
Opinion: When the material of the crankshaft is changed from ductile iron to forged steel, or when a new ductile iron crankshaft is replaced, the counterweight iron cannot be dispensed with. As for whether the original one can be used, it depends on whether it can meet the "counterweight" requirements. It’s about whether a balance can be achieved.
For this problem, you should contact the original manufacturer and recalculate the unbalanced force according to the new crankshaft material to determine whether the counterweight iron is still needed and the weight of the counterweight.
The counterweight should be calculated. There is still a big difference in quality between the old and new crankshafts!
It should be re-balanced and re-weighted. The quality of the new shaft and the old shaft will not be the same. This is necessary.
