# Industrial Specification: Drive Wheels

## 1. Technical Definition
Wheels that provide propulsion and steering for trolleys through mechanical or motorized systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 kN·m torque, 0-15 km/h linear velocity, 0-100 rpm rotational speed**. Failure boundary: **Bearing fatigue failure at 10^7 cycles under 2.5 kN·m torque, gear tooth fracture at 3.5 kN·m torque, motor winding insulation breakdown at 150°C**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa causes subsurface crack initiation in bearing races; bending stress exceeding 400 MPa at gear tooth root causes brittle fracture; Arrhenius degradation of polymer insulation at temperatures above 130°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Lubricant film thickness reduction below 0.1 μm due to particulate contamination | 8 | Adhesive wear and seizure at wheel bearing interfaces | Install 10 μm absolute filtration system with pressure differential monitoring at 0.5 bar threshold |
| Permanent magnet demagnetization from 120°C Curie temperature exposure | 8 | Torque output reduction to 40% of rated capacity | Embed NTC thermistors with thermal cutoff at 105°C and ferrite core material selection with 180°C Curie point |

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

### Q: What materials are best for drive wheels in heavy machinery applications?
**A**: For heavy machinery, polyurethane and rubber drive wheels offer excellent durability and traction, while steel and aluminum provide maximum load capacity for industrial environments.

### Q: How do drive wheels differ from standard caster wheels?
**A**: Drive wheels are specifically designed for propulsion and steering systems with integrated mechanical or motorized components, while standard caster wheels are primarily for passive rolling and maneuverability.

### Q: What maintenance do drive wheel assemblies require?
**A**: Regular inspection of bearings, tire tread wear, and swivel mechanisms is recommended. Lubrication of moving parts and checking mounting bracket integrity will ensure optimal performance and longevity.
