This is a 3D CAD model of a generic spider gear casing, commonly used in automotive differential systems to house the bevel or planetary gears (also known as spider gears). The design represents a simplified but realistic geometry suitable for educational purposes, mechanical assemblies, or FEA/CFD simulations.
The model is built in CATIA and includes features such as gear pockets, mounting surfaces, and structural contours typical of a differential gear housing. It is provided in multiple formats for maximum compatibility.
Features:
- Generic differential spider gear casing geometry
- Designed in CATIA with clean and structured features
- Ideal for transmission system layout and assembly studies
- Suitable for FEA structural simulation or topology optimization
- Compatible with most CAD platforms via STEP and IGES
Applications:
- Automotive drivetrain simulations
- Transmission system design
- Mechanical engineering education
- FEA stress or vibration testing
- CAD libraries for assemblies or part replacements
File formats:
- CATIA .CATPart
- STEP (.stp)
- IGES (.igs)
- STL (optional for meshing or visualization)
