well thanks for your reply , but my work here is just to study , i dont own anything , i just want approaches and help on how to do the right relative calculations .

due to the spline geometry ? its a home engineered replacement . the reducer do have a support , and i believe its the original designed one . so its taking the correct weight. they cant stop the machine mid cycle , so maximum time of operation with a failed shaft is less than 3 hours . no ...

The bearings are mounted on the shaft surface adjacent to the shoulder, u can conclude that from the 3d model above

well the machine still works , even after the failure of one of the shafts , since it has 8 of those . and the frequency is not like 1 day or 1 week .

indeed its a fatigue loading and yes i meant calculations .

im looking more in the anlysis steps , more than directly assuming the causes , cause i need to make a full analysis , but here is the photograph anyway

I’m working on an engineering project analyzing the cause of repeated shaft failure in a translation gear reducer that drives a support wheel of a 400-ton bucket wheel excavator. System Details Shaft material: 42CrMo4 Motor power: 5.5 kW , n=1000 t/min Reducer output power: 4 kW Gear ratio...
