# Industrial Specification: Indexing Drive Unit

## 1. Technical Definition
A precision mechanical drive component that provides controlled rotational indexing motion to a turntable system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 NÂ·m torque, 0.1-5.0 rpm rotational speed, Â±0.01Â° angular positioning accuracy**. Failure boundary: **Torque exceeding 4.2 NÂ·m causes gear tooth shear failure at 350 MPa stress, angular error exceeding Â±0.05Â° triggers system shutdown**, Mechanism: **Hertzian contact stress exceeding 1.1 GPa at cam-follower interface causes pitting fatigue, thermal expansion mismatch (Î”Î±=12Ã—10â»â¶ Kâ»Â¹) between steel and aluminum components induces binding at Î”T&gt;80Â°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.
