# Industrial Specification: Star Wheel

## 1. Technical Definition
A rotating mechanical component with star-shaped protrusions used for precise bottle positioning and transfer in packaging lines.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 N·m torque at 15-60 RPM, 0.01-0.05 mm radial runout tolerance**. Failure boundary: **Material yield strength exceeded at 350 MPa stress concentration at star tip fillets, 0.1 mm wear on positioning surfaces**, Mechanism: **Contact fatigue from Hertzian stress cycles exceeding 10⁷ cycles at 2.5 N·m loading, abrasive wear from glass-on-steel coefficient of friction μ=0.15**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

- **Caution**: 

### Q: What materials are best for star wheels in high-speed packaging applications?
**A**: For high-speed applications, stainless steel offers durability and precision, while engineering plastics like Acetal (POM) provide smooth operation, reduced noise, and resistance to wear without damaging bottles.

### Q: How do pocket inserts enhance star wheel performance?
**A**: Pocket inserts are replaceable components that fit into the star points/arms, allowing for easy customization to different bottle sizes and shapes, reducing downtime and maintenance costs while ensuring secure handling.

### Q: Can star wheels be customized for specific packaging line configurations?
**A**: Yes, star wheels can be customized with specific hub designs, star point counts, pocket insert shapes, and mounting hole patterns to match your machinery's speed, bottle type, and spatial requirements for optimal integration.
