# Industrial Specification: Output Hub

## 1. Technical Definition
The rotating component in a clutch or coupling that transmits torque from the driving member to the driven shaft or system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-4500 N·m torque transmission, 0-6000 rpm rotational speed, -40°C to 150°C operating temperature**. Failure boundary: **Shear stress exceeding 350 MPa at spline interface, torsional deflection exceeding 0.15° per meter of shaft length, surface temperature exceeding 200°C at friction surfaces**, Mechanism: **Torsional fatigue failure due to alternating shear stresses exceeding the endurance limit of SAE 4140 steel (approximately 240 MPa), thermal degradation of friction material beyond 180°C glass transition temperature, fretting wear at spline connections with relative motion exceeding 25 μm amplitude**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.05 mm/mm angular offset between driving and driven shafts | 8 | Accelerated spline wear leading to backlash exceeding 0.5 mm, vibration amplitude increase to 8 mm/s RMS | Precision ground spline teeth with 0.01 mm tolerance, laser alignment during installation, flexible coupling with 3° angular misalignment capacity |
| Insufficient lubrication film thickness below 1 μm at friction interface | 8 | Boundary lubrication regime causing coefficient of friction increase from 0.12 to 0.45, thermal runaway to 250°C surface temperature | Forced oil circulation at 2 L/min flow rate, synthetic lubricant with 320 cSt viscosity at 40°C, temperature monitoring with shutdown at 180°C |
