# Industrial Specification: Carriage (Y-axis)

## 1. Technical Definition
A movable component that travels along the Y-axis of a bridge or gantry machine structure, typically carrying the tool head or workpiece.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 m/s linear velocity, 0.01-0.05 mm positioning accuracy, 100-5000 N load capacity**. Failure boundary: **Linear guide rail deformation exceeding 0.1 mm/m deflection, ball screw backlash exceeding 0.005 mm, recirculating ball bearing temperature exceeding 80°C**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa at ball/rail interface causes plastic deformation, thermal expansion mismatch between aluminum carriage (23.1×10⁻⁶/K) and steel rails (11.0×10⁻⁶/K) induces binding at ΔT&gt;40°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Lubricant starvation in linear guideways below 0.1 μm oil film thickness | 8 | Increased friction coefficient from 0.002 to &gt;0.1 causes servo motor overload at &gt;150% rated torque | Integrated oil-air lubrication system with 0.3 MPa pressure monitoring and 5 mL/hour flow rate per bearing block |
| Ball screw preload loss below 2% of dynamic load rating due to nut wear | 8 | Positioning error accumulation exceeding ±0.01 mm over 1 m travel distance | Double-nut preload mechanism with 10 N·m torque maintenance and laser interferometer calibration at 0.001 mm resolution |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for Y-axis carriages in machinery manufacturing?
**A**: Our Y-axis carriages are available in cast iron for maximum rigidity and vibration damping, welded steel for strength and cost-effectiveness, and aluminum alloy for lightweight applications requiring high-speed movement.

### Q: How does the carriage assembly ensure precise Y-axis movement?
**A**: The carriage integrates linear guide blocks for smooth, low-friction travel along the Y-axis rails, combined with a ball screw nut bracket that converts rotary motion to precise linear movement with minimal backlash.

### Q: What maintenance do Y-axis carriages require in industrial environments?
**A**: Regular lubrication of linear guides and ball screws is essential. Way covers (bellows) protect critical components from chips, coolant, and debris, significantly reducing maintenance needs and extending service life.
