# Industrial Specification: Swing Gearbox

## 1. Technical Definition
A gearbox assembly that enables controlled rotational movement in machinery.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 kN·m torque, 0-1500 rpm input speed, -20°C to 120°C ambient temperature**. Failure boundary: **Gear tooth surface contact stress exceeding 1500 MPa (ISO 6336 Grade 6 steel yield strength), bearing L10 life &lt; 1000 hours at rated load**, Mechanism: **Pitting fatigue failure due to Hertzian contact stress exceeding material endurance limit at gear meshing interfaces, accelerated by inadequate lubrication film thickness &lt; 0.1 μm (λ ratio &lt; 1)**.

### 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.
