# Industrial Specification: Drive Assembly

## 1. Technical Definition
The mechanical power transmission system that provides rotational force to operate a rotary feeder or screw feeder.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 kW at 1500-3000 RPM with torque 3.2-32 N·m**. Failure boundary: **Bearing temperature exceeding 120°C or vibration amplitude surpassing 7.1 mm/s RMS**, Mechanism: **Thermal expansion mismatch between steel shaft (α=11.5×10⁻⁶/K) and aluminum housing (α=23.1×10⁻⁶/K) causing bearing seizure at ΔT&gt;80K**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$
