|
Oil wedge |
An oil wedge can be formed by having a rounded leading edge. The moving block must be floating and able to tilt freely. |
|
|
Types of oil lubrication? |
- Oil baths (where the working surfaces are partly submerged, and oil is picked up and coated over the mechanism) - Splash lubrication (where rotating parts dip into the oil, and splash over all internal parts) - Forced lubrication (engine pump) |
|
|
Grease lubrication |
- Grease guns with grease nipple - Pressure/Spring fed lubricators |
|
|
Oil and grease contaminants? |
- Dirt - Salts - Fuel - Water - The wrong oil |
|
|
How do you minimise contamination? |
- Use only clean and closed cans for topping up - Always use a funnel, fitted with a gauze strainer - Always keep machinery clean - After topping up, close all oil containers and sumps - Only use grease from closed containers |
|
|
Precautions when dealing with lubricants? |
- Use the right oil - Use the right grease - Remember oil and greases are flammable - Grease guns can be dangerous - Remember lubrication routines |
