Why Would Gears Affect Lubrication Effectiveness During Use? Gear Manufacturers Explain.

1. Load striking: For instance, the law power emitted by the engine requires a thicker oil to prevent the immediate fracturing of the oil film and to ensure boundary lubrication, as only a small amount of lubricant can be left behind. In such cases, a lubricant containing extreme pressure additives (EP) is necessary.

2. High-viscosity oils (under high loads or pressures) can withstand heavier burdens and prevent metal-to-metal contact more effectively than thinner oils. Therefore, light loads require low-viscosity lubricants, while heavy loads demand high-viscosity lubricants.

3. Speed: The faster the sliding and rotation, the less time there is for lubricant to be squeezed into the精密 gears. Additionally, at high speeds, lubricants tend to clot and thicken more easily. Therefore, use high-viscosity (thick oil) at low speeds and low-viscosity oil (thin oil) at high speeds.

4. Temperature: As temperatures drop, lubricants become thicker. Conversely, they thin out as temperatures rise. Therefore, low-viscosity lubricating oils are required in low-temperature conditions, while heavy oils are needed in high-temperature conditions to prevent dry friction between metal surfaces.
