⚙️ Engine Valve Train Components (Spring Retainers & Keepers)
Small precision conical/cylindrical parts with internal taper for valve stem locking, external spring seat shoulder, lightweighting grooves
Design Principles
Material: Ti-153 (Ti-15V-3Cr-3Sn-3Al) is a beta alloy offering ultra-high strength (>1200MPa) with excellent fatigue life, providing 40% weight reduction vs steel retainers for high-RPM engines.
Form: Small diameter bar stock for CNC turning of retainers and keepers. Multi-spindle automatic lathes enable high-volume production.
Engineering Trends
- ▸ Process: CNC multi-spindle turning
- ▸ Process: Heat treatment (STA)
- ▸ Process: Surface shot peening
