# Industrial Specification: Bottle Positioning Starwheel

## 1. Technical Definition
A rotating mechanical component within a capping station that precisely positions bottles for cap application.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 NÂ·m torque at 15-60 RPM rotational speed**. Failure boundary: **Exceeds 3.0 NÂ·m torque at 75 RPM or experiences &gt;0.1 mm radial runout**, Mechanism: **Bending fatigue failure due to cyclic stress concentration at starwheel pocket edges (Ïƒ_max &gt; 250 MPa yield strength of 304 stainless steel)**.

### 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**: 
- **Caution**: 

### Q: What materials are used in bottle positioning starwheels?
**A**: Bottle positioning starwheels are typically constructed from corrosion-resistant stainless steel (grades 304 or 316) or durable engineering plastics like Acetal or UHMW-PE for smooth operation and longevity.

### Q: How does a starwheel improve capping accuracy in beverage manufacturing?
**A**: The starwheel's rotating design with precisely machined pockets positions bottles at exact intervals, ensuring consistent alignment with capping heads for secure, uniform cap application and reduced production errors.

### Q: What are the main components of a bottle positioning starwheel?
**A**: Key components include the main body/disc that rotates, a mounting hub for secure attachment to machinery, and replaceable pocket inserts that cradle bottles during the capping process.
