Mix-Kneader Main Shaft (FEA Simplified)

Create an editable 3D CAD model for a Mix-kneader shaft assembly intended for finite element analysis in ANSYS Mechanical. **Known dimensions from the research paper:** - Main shaft: 425 mm overall length, 50 mm diameter. - Pinion: 260 mm diameter. - Gear: 390 mm diameter. - Bearing location: 150 mm from the left end of the shaft. **Modelling requirements:** 1. Use millimetres as the unit system. 2. Create the shaft as a clean, solid cylindrical body. 3. Represent the pinion and gear using simplified smooth cylindrical bodies, without gear teeth. 4. Keep components as separate solids wherever practical. 5. Include the bearing, coupling and blade attachment only where their geometry and positions are sufficiently supported by the reference information. 6. Make the model suitable for export to STEP format and subsequent import into ANSYS Mechanical. 7. Avoid unnecessary decorative details and tiny features that could complicate meshing. **Important accuracy requirements:** - Do not invent missing dimensions, component positions, shaft shoulders or mounting details. - Do not assume that the gear, pinion and bearing are all mounted at specific locations unless those locations are supported by the reference. - If a required dimension or assembly relationship is missing, list it explicitly and ask for clarification. - Clearly distinguish the simplified geometry from an exact reproduction of the published assembly. First generate the shaft using the known dimensions. Then identify the additional information required to complete the assembly accurately.
