# Industrial Specification: Coupling/Belt System

## 1. Technical Definition
A mechanical system that transmits torque and rotational motion between motor and driven equipment components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 N·m torque transmission, 500-6000 RPM rotational speed, 20-120°C operating temperature**. Failure boundary: **Belt tensile strength exceeds 150 MPa, misalignment exceeds 0.5° angular deviation, belt tension exceeds 80% of yield strength**, Mechanism: **V-belt slippage due to insufficient friction coefficient (μ&lt;0.25), belt fatigue from cyclic bending stress exceeding 50 MPa, resonance at 2× rotational frequency causing amplitude &gt;0.1 mm**.

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

- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this coupling/belt system?
**A**: Our coupling/belt systems are constructed from durable materials including steel for structural components, aluminum alloy for lightweight hubs, polyurethane and rubber for flexible elements, and nylon for certain wear-resistant parts.

### Q: How does this system transmit torque between motor and equipment?
**A**: The system uses a combination of coupling hubs that connect to motor and equipment shafts, with drive belts and pulleys that transfer rotational motion through flexible elements, allowing for misalignment compensation and vibration damping.

### Q: What are the main components in the BOM for this system?
**A**: The bill of materials includes four key components: coupling hubs for shaft connection, drive belts for power transmission, flexible elements for vibration absorption, and pulleys for belt guidance and tension management.
