# Industrial Specification: Container Infeed Starwheel

## 1. Technical Definition
A rotating star-shaped wheel that precisely positions and feeds containers into a high-speed rotary bottle filling machine.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 mm radial positioning tolerance at 300-1200 containers/minute feed rate**. Failure boundary: **Starwheel tip deflection exceeding 0.25 mm at 1500 N radial load or angular velocity exceeding 125 rad/s**, Mechanism: **Bending fatigue failure due to cyclic Hertzian contact stresses exceeding 450 MPa yield strength of 4140 steel at starwheel-container contact points**.

### 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 beverage container infeed starwheels?
**A**: Stainless steel (304 or 316 grade) is ideal for durability and hygiene in beverage production. Engineering plastics like Acetal or UHMW-PE offer lightweight, low-friction alternatives for specific applications.

### Q: How does a starwheel improve filling machine efficiency?
**A**: The starwheel's rotating star-shaped design precisely positions containers at consistent intervals, ensuring smooth, uninterrupted feeding into high-speed rotary filling machines, reducing jams and maximizing throughput.

### Q: What maintenance do container infeed starwheels require?
**A**: Regular cleaning to prevent product buildup, inspection of pocket inserts for wear, lubrication of drive components, and verification of alignment with guide rails to maintain positioning accuracy.
