Block Diagram
A block diagram is a graphical representation of a system where the principal parts or functions are represented by blocks and connected by lines that show the relationships of the blocks.

Key Elements of a Block Diagram
- Blocks: Represent the components or processes within the system. 1. Block diagram – Wikipedia en.wikipedia.org
- Lines: Indicate the flow of information, signals, or materials between blocks. 1. Understanding the Basics of a Block Diagram – Creately creately.com
- Arrows: Often used on lines to show direction of flow. 1. What is a Block Diagram and How to Create One – Miro miro.com
Purpose of Block Diagrams
- Visual Representation: Provides a clear and concise overview of a system. 1. Learn about Block Diagrams, See Examples – SmartDraw www.smartdraw.com

block diagram of a lubricating oil system for reduction gearing
Components and their functions:
- Oil Sump: Reservoir for storing the lubricating oil.
- Oil Pump: Circulates the oil through the system.
- Oil Filter: Removes contaminants from the oil.
- Oil Cooler: Maintains the oil temperature within operating limits.
- Oil Pressure Gauge: Monitors the oil pressure in the system.
- Oil Temperature Gauge: Monitors the oil temperature in the system.
- Reduction Gear: The main component to be lubricated.
- Oil Return Lines: Returns the oil to the sump after circulating through the system.
- Safety Valve: Prevents excessive oil pressure.
- Pressure Relief Valve: Protects the system from overpressure.
Additional Components:
- Oil Level Sensor: Monitors the oil level in the sump.
- Oil Condition Sensor: Monitors the condition of the oil (e.g., wear particles, water content).
- Oil Heater: Used in cold climates to maintain oil temperature.
This block diagram provides a basic overview of a lubricating oil system for a reduction gear. Actual systems may include additional components or variations based on specific requirements.
