# Industrial Specification: Gearbox/Reducer

## 1. Technical Definition
A mechanical device that reduces rotational speed and increases torque within a slewing drive system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Input speed: 0-1800 RPM, Output torque: 500-15000 N·m, Temperature: -20°C to 90°C, Lubrication pressure: 0.2-0.5 bar**. Failure boundary: **Gear tooth contact stress exceeds 1200 MPa (ISO 6336 Grade 5 steel), Bearing L10 life &lt; 1000 hours, Oil temperature &gt; 110°C, Vibration amplitude &gt; 4.5 mm/s RMS**, Mechanism: **Pitting fatigue failure occurs when Hertzian contact stress surpasses material endurance limit (approximately 600 MPa for case-hardened steel), causing subsurface crack propagation. Thermal expansion mismatch between steel gears (α=11.5×10⁻⁶/°C) and aluminum housing (α=23×10⁻⁶/°C) creates binding at ΔT&gt;40°C.**.

### 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.
