# Industrial Specification: Transmission/Compound

## 1. Technical Definition
A mechanical assembly within a drawworks that transmits and modifies power from the prime mover to the drum shaft.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Input torque: 5000-25000 N·m, Output speed: 0-300 rpm, Lubrication pressure: 1.5-3.0 bar, Operating temperature: 40-90°C**. Failure boundary: **Gear tooth bending stress exceeds 350 MPa (AGMA 2001-D04), Bearing L10 life &lt; 1000 hours, Oil film thickness &lt; 1 μm (Stribeck curve transition), Shaft deflection &gt; 0.1 mm/m**, Mechanism: **Pitting fatigue (Hertzian contact stress &gt; 1.1 GPa), Micropitting from elastohydrodynamic lubrication breakdown, Scuffing due to boundary lubrication failure (λ ratio &lt; 1), Bending fatigue from cyclic loading exceeding endurance limit**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$
