# Industrial Specification: Precision Gearbox/Coupling

## 1. Technical Definition
A high-precision mechanical transmission component that transfers torque and rotational motion between shafts in a calibration pump system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-500 NÂ·m torque, 0-6000 rpm rotational speed, -20Â°C to 120Â°C operating temperature**. Failure boundary: **Torque exceeding 550 NÂ·m causes permanent gear tooth deformation, rotational speed above 6500 rpm induces critical vibration amplitude of 0.5 mm RMS, temperature beyond 130Â°C degrades lubricant viscosity below 68 cSt**, Mechanism: **Hertzian contact stress exceeding 1500 MPa at gear meshing interface causes subsurface fatigue cracks, misalignment-induced bending moment surpassing 200 NÂ·m creates shaft deflection exceeding 0.1 mm/100 mm**.

### 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.
