# Industrial Specification: Sheave Wheel

## 1. Technical Definition
A grooved wheel that guides and supports wire rope or cable within a traveling block assembly.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 kN dynamic load, 0-15 m/s linear rope velocity, -40°C to 120°C ambient temperature**. Failure boundary: **Groove wear depth exceeding 15% of original groove radius, rope contact pressure exceeding 350 MPa, bearing temperature exceeding 150°C**, Mechanism: **Abrasive wear from wire rope micro-slip under cyclic loading, exceeding the Brinell hardness differential between sheave material (typically 200-250 HB) and wire rope (typically 400-500 HB), leading to progressive material removal and groove deformation**.

### 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**: 

### Q: What materials are sheave wheels typically made from?
**A**: Sheave wheels are commonly manufactured from alloy steel for high-strength applications or cast iron for cost-effective durability in machinery and equipment manufacturing.

### Q: How does a sheave wheel function in a traveling block assembly?
**A**: The sheave wheel's grooved design guides and supports wire rope or cable, reducing friction and wear while maintaining proper alignment within the traveling block system.

### Q: What are the main components of a sheave wheel?
**A**: Key components include the flange (side walls), groove (rope/cable channel), and hub (central mounting point) - all engineered for optimal performance and longevity.

## 6. Manufacturing Compliance
- ISO 4183:1995 - BELT DRIVES - CLASSICAL AND NARROW V-BELTS - GROOVED PULLEYS (SYSTEM BASED ON DATUM WIDTH)
