# Industrial Specification: Swing Mechanism

## 1. Technical Definition
Mechanical system enabling horizontal rotation of the shovel's upper structure

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.5 MPa hydraulic pressure, 0-360° continuous rotation, 0.05-0.8 rad/s angular velocity**. Failure boundary: **Hydraulic pressure exceeding 4.2 MPa causes seal extrusion, gear tooth bending stress surpassing 450 MPa, bearing temperature exceeding 120°C**, Mechanism: **Hydraulic fluid viscosity breakdown at 120°C reduces film thickness below 1 μm, causing boundary lubrication failure; gear tooth pitting fatigue at contact stress &gt;1500 MPa**.

### 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.
