# Industrial Specification: Main Drive Gearbox

## 1. Technical Definition
The primary power transmission component that reduces motor speed and increases torque for the screw shaft in an oil extraction press.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Input speed: 1500-3000 RPM, Output torque: 5000-15000 N·m, Operating temperature: 40-80°C, Lubrication pressure: 2-4 bar**. Failure boundary: **Tooth bending stress exceeds 250 MPa (ISO 6336 Grade 6 steel yield limit), Oil film thickness drops below 1.5 μm (minimum hydrodynamic lubrication threshold), Bearing temperature exceeds 120°C (lubricant thermal breakdown point)**, Mechanism: **Pitting fatigue from Hertzian contact stress exceeding 1500 MPa at gear mesh interface, Micro-pitting initiates at surface roughness Ra &gt; 0.4 μm under boundary lubrication conditions**.

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

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

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

### Q: What materials are used in your main drive gearbox construction?
**A**: Our gearboxes feature alloy steel gears (20CrMnTi or 42CrMo) for strength and wear resistance, housed in durable cast iron casings for stability and vibration dampening.

### Q: How does this gearbox improve oil extraction press performance?
**A**: By efficiently reducing motor speed and increasing torque for the screw shaft, it ensures consistent pressure and optimal oil yield while minimizing energy consumption.

### Q: What maintenance is required for this industrial gearbox?
**A**: Regular lubrication of bearings and gears, periodic seal inspections to prevent leaks, and monitoring of gear alignment and wear patterns as outlined in our maintenance manual.
