The SCP Machine serves the purpose of stamping coking coal into cake, charging it into the oven, and pushing out the resulting coke. The machine's long travel involves 8 double-wheeled bogies, with one serving as the drive wheel and the others as driven wheels. These wheels are interference fitted onto their shafts. The drive wheel sets have shaft extensions with hollow shaft gear boxes attached using shrink disc assemblies. Upon dismantling a broken shaft, it was observed that a cup and cone shape had formed in the middle, and the outer surface was severely rubbed during rotation leading to the failure. The space between the shaft and the DE side bearing showed significant wear and deformation due to rotation. The shaft and DE side bearing were sent to a scientific lab for material analysis. While moving the wheels with some load, the wheel shafts were found to get damaged, prompting an investigation to identify the issues causing the breakage under various conditions. The design and analysis of the wheel and shaft assembly were carried out using CREO & ANSYS Software, complemented by manual calculations in MS Excel.
