Objective
- Developing new, forming-based process chains for hollow gear shafts
- Designing more resource-efficient partial processes; improving final component properties
- Exploiting lightweight construction potential (from the solid shaft to the hollow shaft, i.e. more compact gear units)
Approach
- Substitution of machining processes by more resource-efficient forming processes
- Introduction of effects from forming technology into the gear components
Development objectives
Spin extrusion:
- Raw material: 40% reduction
- Component mass: 30% reduction
- Processing costs: 10% reduction
Gear rolling:
- Raw material: 30% reduction
- Process time: 50% reduction
- Load-bearing capacities: 20% increase
Benefit
- Reduction of process times and material usage
- Improvement of final component properties (strength, wear, surface topography)
- Shortening of complete process chains
- More economic production of gear components
