# Industrial Specification: Drive Roller Assembly

## 1. Technical Definition
A mechanical assembly that provides the driving force to advance packaging material through a dispenser system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 N·m torque at 50-300 RPM**. Failure boundary: **Bearing temperature exceeding 120°C or torque transmission loss &gt;15%**, Mechanism: **Bearing seizure due to lubricant breakdown at 120°C, causing increased friction coefficient from 0.002 to &gt;0.15**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| F | Total Tractive Resistance | Engineering Constant |
