# Industrial Specification: Gear Set

## 1. Technical Definition
A collection of two or more gears that work together to transmit motion and torque between rotating shafts within a drive system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Contact stress 0.8-1.5 GPa, bending stress 200-400 MPa, temperature -40°C to 120°C, rotational speed 100-10,000 RPM**. Failure boundary: **Contact stress exceeds 2.0 GPa (Hertzian contact yield strength), bending stress exceeds 600 MPa (gear tooth yield strength), temperature exceeds 150°C (lubricant breakdown), rotational speed exceeds 12,000 RPM (centrifugal force deformation)**, Mechanism: **Hertzian contact fatigue (pitting) at stress concentrations exceeding material endurance limit, bending fatigue (tooth breakage) from cyclic loading exceeding Goodman diagram limits, thermal expansion mismatch causing binding at differential CTE &gt; 15 ppm/°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.05 mm/mm shaft deflection | 8 | Uneven tooth contact pattern leading to localized pitting and spalling | Precision ground shafts with 0.01 mm tolerance, crowned gear teeth with 0.02 mm crown height, rigid housing with stiffness &gt; 10^7 N/m |
| Insufficient lubrication film thickness &lt; 0.5 μm (λ ratio &lt; 1) | 8 | Boundary lubrication causing adhesive wear and scuffing | EP additive gear oil with viscosity &gt; 220 cSt at 40°C, forced lubrication system with flow rate &gt; 2 L/min per gear mesh, surface finish &lt; 0.4 μm Ra |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

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

### Q: What materials are available for your gear sets?
**A**: Our gear sets are manufactured in steel, cast iron, bronze, and plastic to suit various industrial applications and operating conditions.

### Q: What components are included in a standard gear set?
**A**: Each gear set includes a pinion gear, gear wheel, gear shaft, and bearing - all precision-engineered to work together seamlessly in drive systems.

### Q: How do gear sets transmit motion between shafts?
**A**: Gear sets work by meshing two or more gears together to efficiently transfer rotational motion and torque between different shafts within machinery drive systems.
