# Industrial Specification: Rotary Base

## 1. Technical Definition
The foundational rotating platform of a nozzle magazine/carousel system that enables indexed positioning of nozzles.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 rpm rotational speed, 0.01-0.05 mm radial runout tolerance, 0.1-0.3 N·m torque capacity**. Failure boundary: **Exceeding 3.0 rpm causes bearing skidding, exceeding 0.08 mm runout causes nozzle misalignment &gt;0.5°, exceeding 0.4 N·m torque causes gear tooth shear stress &gt;250 MPa**, Mechanism: **Bearing skidding at &gt;3.0 rpm due to insufficient lubricant film thickness (Stribeck curve transition), gear tooth shear failure at &gt;250 MPa stress (exceeding AISI 4140 steel yield strength), radial runout &gt;0.08 mm causing centrifugal force imbalance &gt;15 N**.

### 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.
