Friction is the force that opposes motion between two surfaces in contact. In U-joints, friction is generated as the various components move against each other. Friction can lead to wear, heat generation, and reduced efficiency.

13.2. Types of Wear

There are several types of wear that can affect U-joints, including:

• Adhesive Wear: Occurs when two surfaces stick together and then separate, causing material to be transferred from one surface to the other.
• Abrasive Wear: Occurs when hard particles or surfaces scratch against softer surfaces, removing material.
• Corrosive Wear: Occurs when chemical reactions corrode the surfaces of the U-joint components.
• Fatigue Wear: Occurs when repeated stress causes cracks to form and propagate, eventually leading to failure.

13.3. How Lubrication Reduces Friction and Wear

Lubrication reduces friction and wear by creating a thin film between the moving parts of the U-joint. This film separates the surfaces, preventing direct contact and reducing the amount of friction generated.

13.4. Properties of Effective Lubricants

Effective lubricants for U-joints should possess the following properties:

• Viscosity: The lubricant should have the appropriate viscosity to maintain a stable film between the moving parts.
• Extreme Pressure (EP) Additives: EP additives help to prevent wear under high loads and pressures.
• Corrosion Inhibitors: Corrosion inhibitors protect the U-joint components from corrosion.
• Oxidation Stability: The lubricant should resist oxidation, which can lead to sludge formation and reduced performance.
• Water Resistance: The lubricant should resist water washout, maintaining its lubricating properties even in wet conditions.

13.5. The Impact of Temperature

Temperature can significantly affect the performance of lubricants. High temperatures can cause lubricants to thin out and lose their lubricating properties, while low temperatures can cause them to thicken and become less effective. Choose a lubricant that is designed to perform well in the temperature range your U-joints will be exposed to.
