# Industrial Specification: Lateral Drive System

## 1. Technical Definition
A mechanical system that enables precise lateral (side-to-side) movement of a treatment couch.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 mm/s lateral velocity, 0.01 mm positioning accuracy, 500-2000 N lateral force capacity**. Failure boundary: **Ball screw backlash exceeding 0.005 mm, linear guideway friction coefficient exceeding 0.003, servo motor torque ripple exceeding 2% of rated torque**, Mechanism: **Hertzian contact stress exceeding 1500 MPa in ball screw/ball nut interface causes plastic deformation; Stribeck curve transition from boundary to mixed lubrication at 0.1 m/s causes stick-slip instability**.

### 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.
