# Industrial Specification: Elevation Gear Assembly

## 1. Technical Definition
A mechanical assembly of gears and related components designed to transmit torque and control angular movement for elevation adjustment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 N·m torque transmission, -20°C to 120°C ambient temperature, 0-3000 RPM rotational speed**. Failure boundary: **Tooth bending stress exceeding 250 MPa (AGMA Grade 2 steel yield strength), surface contact stress surpassing 1500 MPa (pitting limit), backlash exceeding 0.15 mm (ISO 1328-1 Class 7 tolerance)**, Mechanism: **Hertzian contact stress-induced micropitting at gear tooth interfaces due to cyclic loading exceeding material endurance limit (S-N curve fatigue failure), compounded by lubricant film breakdown below 0.1 μm thickness (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.
