# Industrial Specification: Gear Reduction Assembly

## 1. Technical Definition
A mechanical assembly that reduces rotational speed while increasing torque within a drive system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Input speed: 500-3600 RPM, Output torque: 50-500 N·m, Temperature: -20°C to 120°C, Lubrication pressure: 0.2-0.5 MPa**. Failure boundary: **Gear tooth bending stress exceeds 250 MPa (AGMA 2001-D04), Bearing L10 life &lt; 1000 hours, Oil film thickness &lt; 1 μm (Stribeck curve transition), Temperature &gt; 150°C (lubricant breakdown)**, Mechanism: **Pitting fatigue (Hertzian contact stress &gt; 1.5 GPa), Scuffing (flash temperature &gt; 150°C), Micropitting (λ ratio &lt; 1), Tooth bending fatigue (Lewis equation stress concentration)**.

### 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.
