# Industrial Specification: Drive Hub

## 1. Technical Definition
The central rotating component of a torque limiting clutch that transmits torque from the input to the output while allowing controlled slip when torque exceeds a preset limit.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-500 N·m torque transmission, 0-3000 rpm rotational speed, -40°C to 120°C operating temperature**. Failure boundary: **Shear stress exceeding 350 MPa in spline teeth, surface temperature exceeding 200°C at friction interface, radial deflection exceeding 0.15 mm at bearing surfaces**, Mechanism: **Adhesive wear at friction surfaces due to exceeding the static friction coefficient limit (μ &gt; 0.35), torsional fatigue failure from cyclic stress exceeding the endurance limit of 4140 steel (σ_e = 280 MPa), thermal degradation of lubricant film at temperatures above 150°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.
