# Industrial Specification: Take-up Pulley

## 1. Technical Definition
A pulley component within a take-up system that maintains proper tension and alignment of moving materials or belts.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 kN belt tension, 0.1-5.0 m/s belt speed, -20°C to 80°C ambient temperature**. Failure boundary: **Bearing fatigue failure at 1×10⁶ cycles under 4.5 kN radial load, belt slip at 0.35 friction coefficient, shaft deflection exceeding 0.15 mm/m**, Mechanism: **Hertzian contact stress exceeding 1.8 GPa in bearing races causes subsurface fatigue cracking; belt-pulley friction coefficient reduction below 0.35 initiates slip; shaft bending moment exceeding 450 N·m induces plastic deformation**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.
